Abstract
Growing population and expanding industry set off the demand for electrical energy and issues, such as the problem of peak load demand, emerge. To balance the supply and load demand problem, the energy management system has the vital role of Electric Peak shaving with the integration of microgrid into the utility grid. The combination of demand-side management with storable energy sources helps us resolve the matters concerned with the peak load demand. However, in a microgrid, whenever the distributed energy sources are interconnected, the DC bus link voltage will vary due to the inherent behavior of each source as they mainly depend on geographical conditions. This work proposes voltage droop control strategy to keep the DC bus link voltage at a constant value. Also, it gives an overlook of the present power sector scenario of India and a reassessment of the demand side management system and how it is utilized in electrical peak shaving.
Highlights
Electrical energy is the backbone and the most essential factor for world growing technology and economic development
Renewable energy sources depend on environmental conditions and can cause variations in the output voltage, which may lead to changes in the DC bus link voltage and increase of the circulating currents in parallel operating converters
The flow of circulating currents will affect the degradation of battery state of charge
Summary
Electrical energy is the backbone and the most essential factor for world growing technology and economic development. RESs take an all-important share in India’s energy generation sector [2] Due to their irregularity in nature, RESs do not always help in reducing the peak demand when generation and consumption mismatch problems occur. High solar irradiance and wind speed when the demand is low can cause issues like voltage regulation, frequency regulation, and system losses in the distribution and transmission networks [3]. Solutions for these issues should overcome by bringing into effective action the comparison of the Demand Side Management (DSM) and Energy Storage System (ESS).
