Study on Mode adaptive control strategy of a Low voltage microgrid
In view of the microgrid mode switch control strategy change, this paper proposes an adaptive switching control method based on virtual synchronous generator model which is suitable for the two operation modes of microgrid . To satisfy the distributed power in power grid operation under the two operation modes of requirements, this method adds an analog low-pass filter module and reactive power control module. In order to guarantee the stable operation of the microgrid, angle, 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 operating mode, also can effectively improve the frequency regulation effect during the disturbance on the islanded state.The stragety reduces the impact of the microgrid pattern conversion that benefits the operation of the micro power grid stability.
