【摘要】：研究基于多代理系統(tǒng)的孤島型微電網(wǎng)二次電壓和頻率控制策略。首先建立孤島型微電網(wǎng)電壓和頻率控制數(shù)學(xué)模型,利用狀態(tài)反饋得到輸入-輸出線性化模型;然后簡要介紹所需的基本圖論原理,并利用內(nèi)模設(shè)計(jì)原理設(shè)計(jì)分布式協(xié)調(diào)二次控制器,避免了集中控制結(jié)構(gòu)下對中央控制器的依賴�；诙啻硐到y(tǒng)的分布式二次控制器通過一定的有向通信網(wǎng)絡(luò)連接,每個(gè)代理只需本地及相鄰節(jié)點(diǎn)信息。最后在PSCAD/EMTDC中建立孤島微網(wǎng)的測試系統(tǒng),通過仿真對所提控制策略的有效性進(jìn)行驗(yàn)證,結(jié)果表明所提策略能夠使頻率和電壓恢復(fù)額定值,同時(shí)保證有功功率分配的準(zhǔn)確性。
[Abstract]:The secondary voltage and frequency control strategy of isolated microgrid based on multi-agent system is studied. Firstly, the mathematical model of voltage and frequency control of isolated microgrid is established, and the input-output linearization model is obtained by using state feedback, and then the basic graph theory principle is briefly introduced. The distributed coordinated quadratic controller is designed based on the principle of internal model design, which avoids the dependence on the central controller under the centralized control structure. The distributed quadratic controller based on multi-agent system is connected by a certain directed communication network. Each agent only needs local and adjacent node information. Finally, an island microgrid testing system is established in PSCAD/EMTDC, and the effectiveness of the proposed control strategy is verified by simulation. The results show that the proposed strategy can restore the frequency and voltage rating and ensure the accuracy of active power allocation.
