Abstract
In view of the change of micro-grid mode switch control strategy, this paper proposes an adaptive switching control method based on virtual synchronous generator model which is suitable for the two operation modes of micro-grid.To satisfy the requirements of distributed power in power grid operation under the two operation modes, this method adds an analog low-pass filter module and reactive power control module.In order to guarantee the stable oper-ation of the micro-grid, angular velocity and active power electric become the control variable of stability controller. Simulation and hardware experiment show that this method can not only ensure the smooth transition between the oper-ating modes, but also can effectively improve the frequency regulation effect during the disturbance on the islanded state .The strategy reduces the impact of the micro-grid pattern conversion that benefits the operation of the micro pow-er grid stability.关键词
