Aiming at control problem of independent micro-grid with distributed energy resources (DERs), its virtual and logical partitions of control device are analyzed. The local stability based on virtual packet and overall rapid stability is achieved. The mathematical model of control strategy and method reducing regulation error are given. RTDS simulation model for micro-grid is built. Effectiveness of rapid stability control method for frequency and voltage of micro-grid is validated. Finally, advantages of the proposed rapid control method for independent micro-grid are summarized. ©, 2015, Power System Technology Press. All right reserved.
