【摘要】：針對(duì)微電網(wǎng)在外界干擾情況下的動(dòng)態(tài)穩(wěn)定性問題,提出了基于多智能體系統(tǒng)的微電網(wǎng)分散協(xié)調(diào)控制策略。多智能體系統(tǒng)構(gòu)建為兩層,在下層智能體中,各分布式發(fā)電單元的分散控制設(shè)計(jì)為雙環(huán)就地控制器,即由基于下垂特性的外環(huán)功率控制器和基于分?jǐn)?shù)階PID的內(nèi)環(huán)電壓電流控制器組成;在上層智能體中,微電網(wǎng)協(xié)調(diào)控制設(shè)計(jì)為H∞魯棒控制器。構(gòu)建了微電網(wǎng)電壓穩(wěn)定性評(píng)估指標(biāo),當(dāng)微電網(wǎng)承受小干擾時(shí),評(píng)估指標(biāo)在安全域內(nèi),此時(shí)則僅依靠分散控制策略來維護(hù)系統(tǒng)的電壓;而當(dāng)有大干擾發(fā)生時(shí),評(píng)估指標(biāo)超出安全域,此時(shí)則起動(dòng)協(xié)調(diào)控制,并與分散控制一起維護(hù)電壓穩(wěn)定。最后,仿真結(jié)果驗(yàn)證了控制策略的有效性。
[Abstract]:Aiming at the dynamic stability of microgrid under external disturbance, a decentralized coordinated control strategy for microgrid based on multi-agent system is proposed. The decentralized control of each distributed generation unit is designed as a double loop local controller, which is composed of an outer loop power controller based on droop characteristics and an inner loop voltage and current controller based on fractional PID. The coordinated control of microgrid is designed as H 鈭，
