The promotion of distributed photovoltaic power generation is still facing many difficulties, in addition to the cost factor, the equipment utilization rate is low, the function is simple, and it has low awareness. To promote the popularization and application of distributed photovoltaic power generation system, in-depth comparative analysis of photovoltaic systems, active power filter and off-line UPS was conducted, functional expansion for distributed photovoltaic systems was proposed. New system configuration and control strategy proposed not only can achieve functions of APF and PV grid connected generation at the same time, but also can compensate the voltage interruption to ensure uninterrupted work for load when the power interruption occurs. Validity and feasibility of the proposed method were proved by the results of experiment and simulation.
