摘要：
In view of the fact that there are difficulties in the adjustment of network voltage and frequency and the seamless switching during fault occurred in distribution network it is hard for traditional current-controlled inverter to cope with the high penetration caused by connecting a lot of distributed generations to distribution network. For this reason, a control strategy based on single-phase voltage-controlled inverter is proposed. Through the design of control loop and setting of control parameters, the equivalent impedance is controllable accurately, besides, its external characteristics can simulate the frequency and voltage control characteristic of synchronous generator to make the inverter possessing the function of adjusting both network voltage and frequency, thus the ability of distribution network to accommodate distributed generation is enhanced. The effectiveness of the proposed control strategy is validated by results of both simulation and experiments.
