Questions related to Power Generation
How will renewable power generation be affected by climate change?
Can energy management and its conversion through electromagnetic conversion into electricity reduce and benefit from its environmental risks and impacts?
The global community has a responsibility to address the environmental concerns for energy purposes by replacing existing coal and hydrocarbon methods with sustainable and efficient energy systems. Hence, current power generation systems are constrained by physical laws that reduce performance by converting more energy into heat. Similarly, the revolution and widespread implementation of renewable energies worldwide have shown that electromagnetic transfer is a viable option for harnessing the induced mechanical energy provided by wind or water into exergy. Exergy focuses on the efficiency of the second law of thermodynamics with the aim of ensuring the availability and quality of energy in energy management systems. Therefore, it is necessary to reduce energy demand by building highly efficient electrical appliances and increasing the quality of energy with the output power generation systems. This chapter provides a single diagram for developing new models and designs for power generation with the aim of developing variable efficiency power systems. In addition, an analysis of magnetism, electromagnetic induction, and magnetic materials will be conducted for design, optimization, and implementation in current power cycles.

Power system operators maintain the stability of the grid through several key measures and strategies. These include:
1. Load Balancing: Power system operators continuously monitor the supply and demand of electricity on the grid. They ensure that the power generation matches the load requirements to maintain a balance between supply and demand. Load forecasting techniques are used to predict future demand, enabling operators to make necessary adjustments in power generation and distribution.
2. Frequency Control: Power system operators closely monitor the system frequency, which is an indicator of the balance between supply and demand. They employ automatic generation control (AGC) systems to adjust the output of power generators in real-time to maintain a stable frequency. If the frequency deviates from the standard range, corrective measures are taken to restore it to the desired level.
3. Voltage Control: Maintaining stable voltage levels is crucial for the efficient operation of the grid. Power system operators utilize voltage control devices, such as transformers, capacitors, and voltage regulators, to regulate and stabilize voltage levels. These devices are adjusted in real-time to ensure that voltage remains within acceptable limits, preventing voltage fluctuations that could disrupt the grid's stability.
4. Reactive Power Compensation: Reactive power is required to maintain voltage levels within acceptable limits. Power system operators employ reactive power compensation devices, such as synchronous condensers and static VAR compensators (SVCs), to provide or absorb reactive power as needed. By managing reactive power flow, operators can maintain grid stability and voltage control.
5. Grid Monitoring and Control: Power system operators utilize advanced monitoring and control systems to continuously monitor the grid's performance. Supervisory control and data acquisition (SCADA) systems, along with real-time data from sensors and meters, provide operators with detailed information on grid conditions. This enables them to identify potential issues and take corrective actions promptly.
6. Grid Planning and Expansion: Power system operators also play a role in long-term grid planning and expansion. They analyze future load growth, renewable energy integration, and infrastructure requirements to ensure that the grid remains stable and reliable. This involves assessing the need for new transmission lines, substations, and power generation capacity to meet future demand.
7. Emergency Response and Restoration: In the event of disruptions or emergencies, power system operators are responsible for coordinating emergency response efforts. They work to quickly identify and isolate faults, reroute power, and restore the grid's stability. This involves close coordination with grid operators, power generation companies, and other stakeholders to minimize the impact of disruptions.
Is it moral, socially and environmentally ethical for large dominant power companies generating energy mainly from burning coal and lignite to turn off other RES-based energy sources, is it consistent with climate policy and is it consistent with human rights?
In a situation of rising energy prices and the need to accelerate the processes of green transformation of the economy, is it moral, social and environmental to shut down the large dominant power companies that generate energy mainly from burning coal and lignite other sources of energy, including mainly the cheapest and emission-free generation of electricity, shutting down power plants based on photovoltaic panels, not accepting periodic increases in energy production generated from the sun and wind, so as not to reduce energy production from dirty, high-emission energy based on burning coal is moral, socially and environmentally ethical, is in line with climate policy and is in line with human rights?
I ask because such an irrational situation exists in the country where I operate. In my opinion, in a situation of rising energy prices and the need to accelerate the processes of green transformation of the economy, the shutdown of power plants based on photovoltaic panels by the large dominant power companies that produce energy mainly from the combustion of coal and lignite other sources of energy, including mainly the cheapest and emission-free production of electricity, not adopting a periodic increase in energy production generated from the sun and wind, so as not to reduce energy production from dirty, high-emission coal-burning power plants is not moral, socially and environmentally ethical, not in line with sound climate policy and not in line with human rights. The key problem with climate, environmental and energy policy is that it is not conducted fairly. Instead, it is conducted haphazardly, shortsightedly, unstrategically and is politicized in the negative sense of the word. Despite the fact that most of the mining sector, coal and lignite mines, companies in the energy sector and the country's largest fuel and energy company, which holds more than 90 percent of the domestic market share in the sale of motor fuels, are state-owned companies and could carry out in an efficient, comprehensive and strategic manner the process of green energy transition, they unfortunately do not do so. There are many indications that climate, environmental and energy policies are being conducted haphazardly and short-sightedly. The full synergy and correlation that should occur between these policies is missing. Unfortunately, economic aspects are also not key, as they are mixed with political aspects, in which the economic calculus is not treated as a principled factor, and this is in addition to the high level of indebtedness of the state's public finance system and the growing level of the budget deficit in the central state budget. The government has pledged to implement the green transformation of the economy in accordance with the European Union's Green Deal plan. The country receives subsidies from the European Union for the implementation of this plan, including subsidies from the National Reconstruction Plan, which should be allocated mainly to efficiently carried out green investments to carry out the green transformation of the energy industry and achieve the goal of building a sustainable, emission-free energy industry in the shortest possible time. However, this is not happening. Onshore wind power development is still administratively and normatively largely restricted. On sunny, cloudless days and when the wind is blowing, additional energy is generated from already installed photovoltaic panels and wind farms, which is not collected from prosumers by large power companies due to unsuitable transmission networks. Besides, the dominant power companies in the market do not collect clean energy from the mentioned RES sources in order not to reduce the production of energy generated by the conventional method of burning coal and lignite. In addition, the dominant energy companies are lobbying in the political sphere to restrict the development of RES and are causing restrictions on the process of issuing permits for citizens to make further connections to the power grid of prosumer wind turbines and/or photovoltaic installations built by citizens. In addition, there is another extension of the start of construction and implementation of the project to build the first nuclear power plant in a country where the energy industry still relies 3/4 on conventional energy production, i.e. on the basis of burning fossils, much of which is imported, there are situations of energy shortages and eggs to buy from abroad, and the quality of air due to the dominance of combustion energy in the heating season is among the worst in Europe. On the basis of my research, I conclude that this activity is immoral, socially and environmentally unethical, does not comply with climate policy and is not compatible with human rights. Confirmation of the aforementioned thesis is provided by the results of the research I described in my publications given below.
In the following article, I have included the results of the research conducted on the connection of the issue of sustainable development, the genesis and meaning of the Sustainable Development Goals, the essence of sustainable development in the context of social, normative, economic, environmental, climate, and human rights aspects, etc. The research also addressed the issue of key determinants of human existential security as an element of the concept of sustainable development.

POLAND'S 2022 ENERGY CRISIS AS A RESULT OF THE WAR IN UKRAINE AND YEARS OF NEGLECT TO CARRY OUT A GREEN TRANSFORMATION OF THE ENERGY SECTOR
In view of the above, I address the following question to the esteemed community of scientists and researchers:
In a situation of rising energy prices and the need to accelerate the processes of green transformation of the economy, does the shutdown of other sources of energy by the large dominant power companies that produce energy mainly from the combustion of coal and lignite, including mainly the cheapest and emission-free production of electricity, shutting down power plants based on photovoltaic panels, not accepting periodic increases in energy production generated from the sun and wind, so as not to reduce energy production from dirty, high-emission power generation based on burning coal is moral, socially and environmentally ethical, is in line with climate policy and is it compatible with human rights?
Is it moral, socially and environmentally ethical for large dominant power companies that generate energy mainly from burning coal and lignite to shut down other RES-based energy sources, is it consistent with climate policy and is it consistent with human rights?

Hello Experts. Generating solar energy using PV systems results always in the variable power generation due to the effects of intermittency. What parameter is mostly affected by solar intermittency on the grid and what techniques do grid operators use to mitigate such effects.
I'm working on a single chamber microbial fuel cell with air-breathing.
Its voltage already reached approximately 400 mV under OCV conditions, but when I used a 1000 ohm external resistor the voltage immediately drops to zero.
I already used a 10K resistor but the voltage hardly reached 30 mV and it's very low.
I don't know what the problem is!

As the penetration of grid-connected solar energy increases, is it technically possible to replace most of the conventional power generations including coal, gas and natural gas in modern power grid? Is there any critical technical challenges we need to overcome? There are various researches ongoing such as virtual inertial (VI)-based inverter, maximum power point tracking (MPPT) and hybrid energy storage system (ESS) to address voltage/frequency instability, IV & PV non-lineality and solar energy non-availability during night time respectively.
Plus, there are many technologies like artificial intelligence (AI), smart grid, blockchain and other advanced terminologies available for solar energy. From these perspectives, will the solar energy eventually replaces conventional power generation or it will be limited as a supplementary energy source for existing power system which is ideal for remote and vast area?
Welcome to exchange your valuable perspectives on the future of solar energy.

I'm trying to simulate a power generation cycle by adsorption / desorption of ammonia in salt / metal (SrCl2..MnCl2) in a bed. Does anyone know that can i use aspen adsorption or not?
i means it is possible to define the specific reaction between ammonia and for example SrCl2?
I'm a graduate student at McMaster University. Now, I'm doing a system optimization project. I'm interested in optimizing the energy storage system applied to Wolfe Island Windfarm. I'd like to make sure where I can obtain the exact power generated by the wind farm in each hour during the whole year. Also, I need the hourly power prediction (power commitment) data for the next hour.
If you have more than one source of power generation, how to select the operating one and exclude another? What is the common technique for optimizing the power source? Is there a technique like this?
This discussion aims to show how the world's investment in power generation is. In Brazil, the current investment is made more in photovoltaic and wind power.

Hello, everyone. Anyone know how to set power generated by the synchronous generator in PSCAD? I tried many ways, but don't understand what determines the limit of generated power.
Hi all,
I am looking for a source to download wind power generation data. The data should fulfill the following requirements:
- measured (not simulated) power generation
- of an individual wind turbine or farm (not country-level or TSO-level data)
- in hourly (or at least daily) resolution
- that spans at least one month (better multiple years)
- that is downloadable (I don't want to see the data, I want to use it)
- free of charge (for academic use)
The geographical scope is open but European data would be optimal. So far, I checked the following sources:
- https://www.energy-charts.de has data for two parks in Germany but I do not see a way to download it
- https://transparency.entsoe.eu has some data but one can only download one day at a time
- https://www.bmreports.com has detailed data for UK but again, downloads are only possible for one day at a time
Alternatively, recommendations for a Python library that can retrieve this kind of data are welcome (specialized libraries - not general web scraping libraries like Selenium, BeautifulSoup, etc.).
For prediction solar energy i need solar power generation data.

I'm currently using Nafion 211 for the proton exchange membrane in my microbial fuel cell experiment. I found lots of articles recommended to use Nafion 117 instead. My experiment was failed, there was no power generated by the fuel cell and I suspect the Nafion 211 can not facilitate the proton exchange in the MFC.
I'm wondering what the difference between 117 and 211 is and could Nafion 211 use for MFC?
I have data on power generation and other variables (e.g Irradiance, temp & wind speed) of last two years(on daily basis). I want to forecast the power generation using SVR so I need its MATLAB code which is easy to understand.
I am looking forward to work on System Modeling and Control theory in Power generation, Aerospace or in Robotics. This is a completely new field for me and i need to do a lot to build the foundation stronger to carry out innovative research. Currently, i am reading books to understand relevant concepts as well as i am reading latest research papers to be familiar with new research in the field. Unfortunately, i am still clueless about this new field.
I need some expert advises from experts in this field that how can i master the concepts and bring the concepts into something which is called innovation.
Looking forward to get the brief answers from you guys.
Thanks
Synchronous generators are rated in MVA where as when we refer to a power plant we refer to their MW rating? Why is this so?
Renewable utility-scale power generation, such as wind, solar, etc, has become much cost-effective and more and more important in the past few years. However, the lower energy transition efficiency and the periodic generating feature constrains the development of renewable energy. These years, energy storage has become a hot research topic. My questions are: Is energy storage really the solution of future energy? If the answer is yes, which kind of energy storage will be the best available technology or the most promising technology for utility-scale power generation? Are there any technical issues that constrain the application of energy storage technologies? When will energy storage technologies become widely applicable?
There are more number of power generation plants like steam, hydroelectric, nuclear, biomass, solar etc. The supply of power from these plants depends on the utilization. Each plant has some advantages and disadvantages for power generation. In this context, what could be the preferred power generation plant?
In Digsilent software,why are the values of current(pu) in a bus connected to this equipment different, when the "Nominal Apparent Power" in generator specifications and the "Rated Power" in transformer specifications are not equal?
What is the benefit of using a physical model to model the power generation (i.el solar field with parabolic trough collectors)? A data-driven method could potentially achieve similar accuracy with massive training data?

Hello everyone.
I am trying to solve this problem where i need to calculate the optimum capacity of PGU in combined cooling heating system (CCHP) using Genetic algorithm.
I have these equations:
The natural gas consumption by the PGU with respect to time can be expressed using the following equation:
Fpgu_t = Epgu_t/ηpgu_t .........(1)
where Fpgu is the natural gas consumed by the PGU.
The efficiency of PGU which is ηpgu, can be calculated as follows:
ηpgu_t = a+bf_t+cf_t^2..............(2)
where a, b, and c are the constant coefficients, and f_t is the partial load rate with respect to time which is the ratio of electricity generated by the PGU to the maximum output (PGU capacity) and can be defined as:
f_t = Epgu_t/(Ecap)...........(3)
A common linear relationship exists between the gas consumption and electricity generated by the PGU , which is widely used to optimize the CCHP systems and is expressed as follows:
Fpgu_t = α×Epgu_t+β........(4)
here i have the values of a,b and c for equation 2 and α and β for equation 4. Also i have common linear relation between the fuel consumption (Fpgu_t )and electricity generated by PGU (Epgu_t) which i have attached.
Other than that i also have a load profile which will be used to calculate the optimum capacity of PGU.
Please anyone can help me with that? I have consulted many different journal papers but i am still very much confused in this part.
Please help. Thanks everyone.

I really need calculations on steam electric power generator
Dear fellow researchers,
is there anyone who has access to, or who can provide me with a good reference of, curves that can provide me with quantitative information about how the electric and thermal power generated by a Solid Oxide Fuel Cell in combined heat and power mode vary with the load of the fuel cell system?
To be more specific, what I would need are curves of the type:
electrical efficiency vs SOFC load
exhaust temperature vs SOFC load
exhaust mass flow vs SOFC load.
I am trying to test the potential use of an SOFC for transportation purposes, and it would be very helpful to have access to this type of information
Currently, I am selecting a power generator for Dielectric barrier discharge (DBD) reactor. I am wondering between 02 devices: AC sinusoidal power generator or Pulse power generator. Which power supply device provides the best performance on the DBD reactor? And in accordance with the method of calculating discharge power DBD using V-Q curve Lissajous (Because I currently have high voltage probes 1000x and monitor capacitors. I don't want to use the high current probe to calculate the discharge power for some reason I don't have this device right now)
If I want to change both voltage V and frequency F for DBD reactor, I need to choose which power supply device. Please suggest me some specific power generator supplies.
I sincerely thank you and wish all the best!
Utilization of solar energy is always one of the meaningful research areas. But most researches are about one or two utilization aspects, such as for cooling, heating, heat storage, power generation, water uptaking, and so on. Is there any completed or ongoing research about the integrated utilization of solar energy to combine all these applications into one whole system?
Greetings,
I need for a simple document ( Paper ) explains the calculations of wind energy power generation..
Thanks

I have data on wind speeds stretching over 5 years. I want to use it to estimate average annual power generation capacity of a 5kW wind turbine.
In February 2018, Trinidad and Tobago signed on to the Paris Climate Change Agreement.
The Ministry of Planning and Development has indicated that "Trinidad and Tobago is committed to conditionally reduce its cumulative carbon emissions by 15% in the power generation, transport and industrialised sectors by 2030".
What initiatives are underway to meet this commitment?
I have a hard form of the book with me. I am looking to have a .pdf version of it. Please share any link where I can have it.
Thank you
Hi All
How exactly is the air or wet cooled condenser sized and controlled in a power plant?
For example, for a wet cooled condenser, is the design/nominal exhaust turbine pressure calculated based on the 1- max wet bulb temperature experienced onsite 2- average wet bulb temperature 3- or average max?
Also, while the plant is operating, say one day the wet bulb temperature was higher than the design value, do plant operators simply increase the cooling water flow rate to ensure the exhaust pressure is fixed or let the turbine exhaust pressure increase which would slightly hurt its power generation?
In other words, do we size and/or control the condenser such that the turbine exhaust pressure is fixed or the exhaust pressure is allowed to float based on weather conditions?
Thank you all
Let's talk about Dose of plasma!
How can we measurment it(in J.cm^-2)?
The energy that we talk about is plasma energy & it related to power of generator?
or we can use the light fiber or ICCD to take spectrum and then compute the energy of the gas(for example argon)?
Is the energy same as radiant exposure?
Many presidents in the Middle East in general and the Arab world in particular, assume power in general elections. But later on, they become dictators and remain in power for tens of years. They even change the terms and items of the constitution for their interests to remain ruling the country as if they are the only ones qualified to be presidents. Your comments are highly appreciated.
Need of a wind energy data-set depending on features like generation amount ,climatic & weather condition,speed of wind etc.
Hello dear scholars,
in the context of the hydropower generation, what is the limit of power generation?
Should I see it limited by the nominal capacity of generators, from above?
Because, I see that in the Turbine Hill-Chart, and its safe operation region, it can produce way more than nominal capacity of the generators of the power plant.
let me know if I could not express my question, clear enough.
Thank you
Am investing the wind and wave activities over the Atlantic with view of ascertaining areas suitable for power generation. What are those factors I should consider?
You can also share with me relevants and helpful materials.
Im doing research on temperature rise in solar cell during open circuit condition or partially loaded. Im sure that when solar cell is in open circuit the energy generated will be transferred as heat and the same will cause degradation of solar cells. Can you help me out with formula or methodology to find the rise in temperature when power generated in solar cells are unused? How long it will take to cool the developed temperature?
We use solar pannel in roof top system for electrical power generation. I wants to know the size that panels.
I'm currently working on a design of a hydroelectric system that can be free of environmental and economic concerns and reliable to operate in Ocean and Sea.
It is a huge project In planning. If you are an expert or have experience in this area, I would greatly appreciate your support to make this project happen.
How do we calculate the voltage dip of a DG Set during the starting of the largest KW motor.?
What are the factors which effects the Vdip value.
Any relevant Standard which can be refereed preferably IEC/IEEE?
Once such formula for calculation the Vdip, I came across was
DG KVA raing required during Starting=1.1 * ((1 - Vdip) / Vdip) *( (Xd' + Xd') /2 )*starting KVA of Largest Motor
where,
Vdip- Voltage Drop during starting of largest motor (here Vdip is considered as 15% )
Xd' - Transient Reactance of the DG
Xd"- Sub Transient Reactance of the DG
Is there any relevant standard for the above formula.

I need a low to medium cost setup to measure solar energy over a long period to evaluate a site for installing small solar or hybrid power generation systems.
We are considering installing 30 MW SPV power generation facility, connected to 11 kV power grid. Th e system is required to supply energy upto 5 MWh during six to seven hours after sun-set per day. We are exploring practical options for neat and clean storage of electricity at the site. The site has more than 300 sunny days in a year. It is desired that system will be operated such that the battery bank will be charged on priority during the day, and excess power will be supplied to grid at the site.
I know its very basic but I have data available for Solar Power Generation from Panels but they are in Watts. Available data is in 15 mins interval. While consumption data available is in Watt hours.
Here is the problem: Generation and consumption data are from different meters hence both have different resolution (timestamps) i wanted to plot these two parameters on same graph but due to difference in resolution i cannot convert Solar power into Watt hours.
How would i convert Solar power into energy (Wh) accurately?
Help would be appreciated. Thanks
coil wound alternators are used everywhere to Generate electric power in all kind generating stations.Though it is demonstrated by vande graf (static generator) it is is not popular in power generation. Let me know the limitations and constraints if any
- It was developed almost 20 years ago for hydrogen storage to be used in power generation.
I am aware of the droop control but i cannot figure out how to implement this in MATLAB. I find papers about the droop control in case of distributed generation units which are connected to the grid by means of an inverter. Here, you can decouple the active and reactive power, generate the reference voltage accordingly and control the power sharing according to the droop control principle. This is no possible in case of synchronous generators where you can change the input power (governor control) and field excitation (excitation control).
Please, I kindly would like to know if it is better to use predictions and measurements for the control of hybrid systems using EMS ? In case of only using measurements of the generated powers and generating the control signals, does the controller gives good results?
Thanks in advance !!
For an undergraduate level course, I need a simple tool for solving optimal economic dispatch (OED), and combined optimal economic and emissions dispach (CEED) based on classical optimization methods. Offline (i.e. without the need of Internet) tools are preferable.
Since the time of Independence India has been deriving its electricity from coal, Hydro and thermal based power plants. the efficiency of power plants and there output is an important aspect, after certain time period it starts to decline.
My query is, does India has some policy to regulate and replace these old power plants and to setup new efficient plants that can fulfill the energy needs. Under what policy these plants are replaced and what is the time duration. Where does the technology for this power plants in India are made is it licensed from other countries or manufactured through joint ventures.
To get active power of the generator to zero but reactive power should be injected to the system for voltage stability.
