Questions related to Power Generation
One technology, carbon capture and storage (CCS), stands tall for its ability to help energy-intensive sectors like power generation and heavy industry reduce their emissions. In fact, the International Energy Agency has said without CCS, achieving the world’s lower-emission targets will be virtually impossible. While the technology isn’t new, it is increasingly coming to the forefront of the climate conversation. But what is carbon capture and storage?
It is well-understood that depends on the power system strength or system inertia in addition to the speed protection system settings.
I just would like to see some typical values for such imbalance either normalized or in MW.
Class C oscillators have advantages of lower phase noise and power consumption. Searching in the literature I cannot find any single ended Class C oscillators. Though, there are Class C single ended power amplifiers. I was wondering if anyone have seen any single ended design, or even if it is possible to have or not?
I'll really appreciate your kind responses.

I have been working on Restoration Plan for the Eastern Grid of Bhutan. this project focuses on restoration procedures in case there is a total blackout in the system. I have been studying the frequency in each restoration step. however, I have not been able to plot the active power generated by each of the plants.
Stabilizing techniques for transistor amplifiers are well known, and as we know the frequency of operation we can make sure of stable operation in that band. However, in oscillators and specifically parallel oscillators which oscillation frequency is wished to be defined by feedback loop length (phase delay) we end up with existing multiple oscillation modes. e.g. equivalent series feedback mode at low frequency.
my question is that in such oscillators how can we make sure of other modes suppression? of course we can check startup condition for modes, how ever this is an analysis technique not synthesis.
my intuition is that as oscillation starts from DC we should keep amplifier stable all the way to oscillation frequency. but I am not sure.
I appreciate it if you share your experience with others.
thanks a lot

Many developing countries utilize various multiple methods for power generation. such as gas and oil turbine, windmill, thermal, nuclear, and hydroelectric depends on topography and natural resources.
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?

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?

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.
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!

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

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
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
