Article
To match supply and demand, shifting of load from peak period to off-peak period is one of the effective solutions. Presently flat rate tariff is used in major part of the world. This type of tariff doesn’t give incentives to the customers if they use electrical energy during off-peak period. If real time pricing (RTP) tariff is used, consumers can...

Residential and commercial sector share up to 40% demand of power grid. For optimal power scheduling of appliances in this sector, power grid must be intelligent enough so that using Information and Communication Technology (ICT), peak demand and Peak to Average Ratio (PAR) can be decreased. Such upgraded grid is called as Smart Grid. In Smart Grid...

Induction motor for many years has been regarded as the workhorse in industrial applications. An induction motor can run only at its rated speed when it is connected directly to the main supply. However many application need variable speed operations. With the invention of variable voltage variable frequency drives (VVVF), the use of an induction m...
Article
Multi-level inverter technology has emerged recently as a very important alternative in the area of medium-voltage high-power energy control. Due to higher number of dc voltage sources, lower EMI, requirement of semiconductor power devices with less blocking voltage, lower % THD in output voltage and less stress on insulation, they are widely used....

The COVID-19 pandemic has affected the health systems severely. It is very difficult task for the all countries of the entire world to make isolated wards and treat the patients in this pandemic situation. Although majority of people of the world have taken vaccine, third wave is started in the majority part of the world. Vaccines are thought to be...

The system presented in this work can be operated from anywhere in the world. It is not required for farmer to be present at farm for irrigation purpose. Farmer can operate the system and know the status of farm regarding irrigation at anytime from anywhere in the world using his mobile. This low cost smart irrigation system with some modification...
Article
Gradually, the share of renewable energy will required to increase in the grid due to bad environmental impact of conventional fuel. Solar and wind energy share major part among renewable energy sources. As the PV (Photo Voltaic) solar power plant is having static equipments and components, its overall efficiency is higher than other types of renew...
Article
Due to a harmful effect on the environment of fossil fuels and limited resources it, non-conventional energy sources are required to integrate with present power grids. Gradually, the share of renewable power will required to increase in the grid. India is one of the fastest growing countries in the world for the installation of the renewable energ...

This paper discusses the simulation and experimental work of small Smart Grid containing ten consumers. Smart Grid is characterized by a two-way flow of real-time information and energy. RTP (Real Time Pricing) based tariff is implemented in this work to reduce peak demand, PAR (peak to average ratio) and cost of energy consumed. In the experimenta...
Article
The concept of shaping domestic and commercial loads can be an effective way of controlling the load profile of a distribution company. Flat energy rates don’t provide incentives to customers to use power as would be optimal from a utility point of view. Price of energy should be fluctuating according to peak or off peak load condition. Smart meter...

Performance of multi-level inverters is highly superior to conventional two-level inverter, so they have been widely used for high-power high-voltage applications. Due to higher number of dc voltage sources, lower EMI, requirement of fewer devices with less blocking voltage, lower %THD in output voltage and less stress on insulation, they are widel...

Third wave of Covid-19 is started in the world and in this wave corona cases rise around five times faster than the second wave. World will see some more waves in the coming years. We can’t say clearly at this stage when this pandemic will end. In such situations sometimes the healthcare system works under stress. So automation is very much helpful in this pandemic. For this purpose one simple low cost robotic vehicle is designed and presented here. Using this robotic vehicle we can sanitize the ward or part of the ward of the hospital. We can also mount a camera on the vehicle for surveillance purposes. We can do many types of modification as per requirement.
