Research on reactive compensation and grid connected photovoltaic control strategy of a nRYHO type energy storage Quasi z source inverter
A combined control strategy of photovoltaic grid connection, reactive power compensation and energy storage was proposed for a novel energy storage quasi z source inverter. According to the different state of the battery, the system applies different control schemes. Based on the control strategy of the battery under normal conditions, this paper analyzes and discusses the unit power facto grid connected while ensuring the maximum utilization of photovoltaic cell energy efficiency and enhancing the stability of grid connected power, and compensates the load with reactive power. Finally, simulation and experiment verify the effectiveness and correctness of the proposed strategy.
