Design and Development of Energy Management System for Hybrid Microgrid

Microgrid is a key solution for integrating distributed generation and energy storage systems. An energy management system can achieve an efficient and optimal operation of microgrids. In this paper, an advanced energy management system algorithm is proposed for the hybrid microgrid to enable diverse energy management goals, including peak shaving, flat power flow, self-consumption, and zero import. Moreover, the controller is developed to discharge/charge the battery energy storage system to achieve goals. The microgrid is modeled in MATLAB/Simulink with a photovoltaic generation system, battery energy storage system, grid, and variable load. The proposed algorithm and controller have been tested in different case studies using actual photovoltaic generation and load data. The simulation results show that the proposed algorithm and controller effectively perform all energy management system operation modes.
