摘要：
To achieve long-term stable operation of islanded microgrid, a control strategy is proposed for photovoltaic (PV)-diesel-storage microgrid with virtual synchronous generator (VSG). A PV-storage system is formed by equipping energy storage on photovoltaic generator side and VSG is used to control inverter. The system is simulated as a synchronous generator (SG). By designing energy management, PV instantaneous output and charge state of storage is feedback to VSG control to adjust active power and frequency output of the system. PV-storage system and diesel generator (DEG) are controlled equally to participate in primary frequency regulation and maintain active power balance of microgrid. Meanwhile, secondary frequency regulation is undertaken by DEG. Maximum PV output and storage state control is realized and flexible control and stable operation of islanded microgrid is ensured. Finally, relevant analysis and the proposed strategy are verified with Matlab/Simulink simulation. © 2017, Power System Technology Press. All right reserved.
