Enabling the Technologies for Incorporating Battery Energy Storage System with Standalone Microgrid

摘要

The incorporation of energy storage system with distributed generation supports the islanded microgrid in remote location. The chapter is intended to develop control framework for battery storage system and incorporate it with the standalone microgrid to present the concept of microgrid as a potential provider of electricity to gridless society. The regulation of the voltage and frequency is the two key aspects of the standalone microgrid. The abrupt load changing scenario directly affects voltage and frequency parameters and it gets deviated from their nominal value results to inaccurate sharing of the apparent power. The energy storage system assists the islanded microgrid and regulates the voltage during change in load condition. The cascaded control mechanism achieves the desired value of voltage with voltage-current, P-f and QV droop. The paper presents the utilization of three droop mechanism to establish the nominal voltage. The robustness of the designed proposed strategy is established through simulation result of MATLAB.
