Control with grid forming of a PV-BESS system for a 4-wire residential microgrid
This paper deals with a battery energy storage system (BESS) with a 4-wires residential microgrid based on photovoltaic and batteries. The key idea is to ensure a gridforming control able to adjust microgrid voltage and frequency while maintaining the equilibrium at the midpoint of the DC bus connected to PV and BESS. In addition, the control algorithm considers the inertia emulating. Simulation results demonstrated the performance of the grid forming with power droop control with PSIM. Experimental results are given to prove the effectiveness of the proposed algorithm with 20 kVA prototype.
