| Abstract: | In view of problem of the existing inverter control method for photovoltaic power system, a kind of the control strategy for parallel switches hierarchical group round robin switching to photovol- taie array/inverter was put forward. The method can make the system power efficiency optimization and enable running time of the grid - connected inverter more balanced, and can improve the lifespan of the grid - connected inverter and the system. MATLAB simulation, validation indicate the control strategy has superiority in energy saving. |
