1、XX丸學(xué)題目：微電網(wǎng)協(xié)調(diào)運行控制策略木文主要通過進(jìn)行了理論研究、仿真平臺搭建，研究微電網(wǎng)綜合協(xié)調(diào)控制策略，，仿真結(jié)果分析，為后續(xù)微電網(wǎng)的深入研究奠定了基礎(chǔ)。木文設(shè)計了PQ控制器、基于下垂特性的V/f控制器，并對逆變器輸出濾波器進(jìn)行了設(shè)計。同時，針對PI控制器的不足，利用模型預(yù)測控制方法設(shè)計了微網(wǎng)小分布式微電源逆變器的PQ模型預(yù)測控制策略和基于下垂特性的V/f模型預(yù)測控制策略，并在MATLAB/Simulink中建立了仿真模型，對單個微電源分別采用PI控制和MPC控制時的不同場景進(jìn)行了分析，證明了MPC控制器的效果
2、。最后，建立了微電網(wǎng)的模型，用風(fēng)力發(fā)電機組、光伏以及蓄電池三種微電源的模型代替直流電壓源，并設(shè)計相應(yīng)的控制策略，在MATLAB/Simulink中，搭建了整個系統(tǒng)的模型，分別在風(fēng)機和光伏陣列出口處配置蓄電池，用于平抑并網(wǎng)功率并在孤島下提高電壓和頻率支撐，仿真結(jié)果驗證了控制策略的可行性。關(guān)鍵詞：微電網(wǎng)；綜合協(xié)調(diào)控制；風(fēng)光儲；逆變器；模型預(yù)測控制StudyontheCoordinationControlStrategyofWind-Solar-StorageMicro-gridAbstractThispapermai
