Abstract:

Aiming at the new energy power generation of distributed photovoltaic (PV) grid system, this paper mainly studied the core of the inverter part in grid connected power generation system. Design a new kind of two-stage grid connected inverter with energy storage device. In addition, aiming at the problem of electricity peak valley when the distribution network load demand change, studies a peak shaving control strategy for the distributed grid-connected PV system with energy storage devices. Present a peak load shaving control strategy based on Point of common coupling voltage compensation. Finally, the parameter design of the whole system is finished, and through software simulation and hardware experiment, the rationality of the two-stage grid connected inverter design is verified. Improve the operation efficiency of PV system, effectively solve the problem of peak load shaving and system stability. Provides technical reference for the design of the distributed photovoltaic grid power system.

Key words: Distributed photovoltaic, flyback inverter, soft switch, battery energy storage system, peak load shaving
