【摘要】:為減小微電網(wǎng)對通信系統(tǒng)的依賴性,實現(xiàn)分布式電源和負荷的即插即用,結(jié)合微電網(wǎng)不同運行模式,研究了微電網(wǎng)對等控制策略。在對等控制策略中,分布式電源采用下垂控制,調(diào)節(jié)分布式電源的輸出電壓和頻率;下垂控制器中的P-f和Q-U具有線性的下垂特性。建立了對等控制策略下的微電網(wǎng)運行模型,分析了并網(wǎng)和孤島運行模式之間切換、孤島模式下切/增負荷及孤島模式下切/增微電源三種運行狀況下的微電網(wǎng)運行特性,基于Matlab/Simulink仿真結(jié)果,研究了微電網(wǎng)母線電壓、DG頻率和功率的變化規(guī)律,驗證了控制策略的正確性和可行性。
[Abstract]:In order to reduce the dependence of microgrid on communication system and realize the plug and play of distributed generation and load, the peer-to-peer control strategy of micro-grid is studied. In the peer-to-peer control strategy, the distributed power supply adopts droop control to adjust the output voltage and frequency of the distributed power supply, and the P-f and Q-U in the droop controller have linear droop characteristics. The operation model of microgrid under peer-to-peer control strategy is established, and the operation characteristics of microgrid under switching between grid-connected and islanding operation mode, cutting / increasing load in islanding mode and cutting / increasing micro-power supply in isolated island mode are analyzed. Based on the simulation results of Matlab/Simulink, the variation rules of bus voltage, DG frequency and power are studied, and the correctness and feasibility of the control strategy are verified.
