Abstract: Microgrid-based energy management system (EMS) is designed and implemented in this paper to manage the energy balance between renewable resources and the load, i.e., supply-demand balance of energy. Wind energy generation is done through PMSG using the method of vector control of synchronous generator. Further, the investigation of modelling and control of state of charge (SOC)-based battery management system (BMS) in microgrid for autonomous/islanding mode is presented in the form of aggregated battery model. Since BMS is critical in maintaining the optimum performance of battery and hence, a battery system has been designed in the present work. The results of the comparative study of the proposed MPPT techniques, i.e., CSA, ANN, FLC with conventional P&O using MATLAB/SIMULINK in terms of accuracy, electric power efficiency, duty cycle, DC link voltages, and load power of proposed techniques are presented in the present work. The working of the proposed EMS for hybrid PV-wind-battery system is verified through simulation results using various control algorithms.
