Active and reactive power optimization control of photovoltaic and energy storage based on grid forming inverters

Currently, grid forming inverters are used to support frequency and voltage in distribution networks. Hence, grid forming inverter is very important for active and reactive power optimization control. This paper first introduces the virtual synchronous generator control method. The Successive Quadratic Programming (SQP) algorithm and particle swarm optimization (PSO) algorithm are respectively used to optimize the active and reactive power control parameters. The simulation results validate that the optimization algorithm can improve the frequency and voltage dynamic performance of the system.
