Energy storage system in microgrid

Abstract

The energy storage systems (ESS) integrated microgrid have grown attention and acceptance because it has power reliability and sustainable energy utilization capability. Several ESS has been introduced with significant characteristics such as performance, size, life cycle, charging/discharging, safety, reliability, capacity, and cost. This chapter comprehensively reviews the types of ESS technologies, configurations, classifications, features, energy conversion, life cycle, and advantages and disadvantages. Moreover, the power electronics converter interfacing the microgrid has also been briefly studied. The present review critically demonstrates the interfacing circuits of ESS to microgrids. The mathematical modeling of bidirectional DC-DC converter interfacing the ESS to DC microgrid is presented developed. Moreover, the modeling and control of VSI interfacing the BESS to a three-phase grid is also demonstrated. The simulation model for both systems is also developed in MATLAB-Simulink. A critical review of the obtained simulation results is presented to show the ability of the DC-DC converter and VSI system for charging the BESS and delivering the power to the microgrid as per the requirement assigned by the higher-level controller of the microgrid. © 2022 Scrivener Publishing LLC.
