摘要：
Virtual synchronous generator has power oscillation problem in the process of dynamic response. In view of the problem,a control strategy based on improved virtual synchronous generator was proposed in this paper. Mathematical model of the virtual synchronous generator was studied,and rotational inertia effect on active power in the process of dynamic response was analyzed in detail. Based on the traditional virtual synchronous generator,the feed- forward compensation control strategy is further adopted,and an improved virtual synchronous generator control strategy is proposed. By adjusting the adjustable parameter of the compensation link could be modified to achieve the goal of reducing system order can be reduced. It can restrain the power oscillation effectively in the process of transition. Simulation and experiment results verify the feasibility and effectiveness of the proposed control strategy. © 2020, Solar Energy Periodical Office Co., Ltd. All right reserved.
