To meet the greenhouse gas reduction targets and address the uncertainty introduced by the surging penetration of stochastic renewable energy sources, energy storage systems are being deployed in microgrids.
Isolated microgrids can be of any size depending on the power loads. In this sense, MGs are made up of an interconnected group of distributed energy resources (DER), including grouping battery energy storage systems (BESS) and loads.
The combination of energy storage and power electronics helps in transforming grid to Smartgrid . Microgrids integrate distributed generation and energy storage units to fulfil the energy demand with uninterrupted continuity and flexibility in supply. Proliferation of microgrids has stimulated the widespread deployment of energy storage systems.
A shunt active filter algorithm for improving the power quality of grid is also implemented with power flow management controller. The overall management system is demonstrated for on grid and off grid modes of microgrid with varying system conditions. A laboratory scale grid–microgrid system is developed and the controllers are implemented. 1.
