摘要：孤島型微電網的內部電力單元通過無線網絡進行通信，無線通信網絡易受擾動并且存在鏈路失效問題，導致通信拓撲不斷變化，使得電力單元控制信號更新失敗。為了消除下垂控制導致的電壓與頻率偏差，針對存在通信網絡切換的孤島電網，提出在切換拓撲下孤島型微電網的分布式二次控制策略。該策略是在下垂控制的基礎上增加切換拓撲的情況以實現二次調節，并且形式簡單，可用構造簡單的硬件來實現。在提出的二次控制作用下可以使頻率和電壓以指數的速度收斂至期望值，保證了有功功率分配性能。利用Matlab/Simulink仿真驗證了該二次控制策略的有效性和可行性。

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
