    Abstract: The internal power unit of the island micro-grid communicates through a wireless network, and the wireless communication network is susceptible to disturbances and has link failure problems, which leads to continuous changes in the communication topology and makes the power unit control signal update failure. In order to eliminate voltage and frequency deviations caused by droop control, a distributed secondary control strategy under switching topology is proposed for islanded micro-grids with communication network switching. The strategy is to increase the switching topology on the basis of droop control to achieve secondary adjustment, and the form is simple, and it can be implemented with simple hardware. Under the action of the proposed secondary control, the frequency and voltage can converge to the expected value at an exponential speed, which ensures the performance of active power distribution. This article uses Matlab/Simulink simulation to verify the effectiveness and feasibility of the secondary control strategy.
    Key words: islanded micro-grid; secondary control; distributed control; switching topology
