        摘 要:針對風(fēng)力發(fā)電、光伏發(fā)電具有受天氣影響大、電壓穩(wěn)定性差的特點(diǎn),STATCOM (靜止同步補(bǔ)償器) 可以動態(tài)地向風(fēng)光儲互補(bǔ)系統(tǒng)注入無功功率從而解決電壓降落的問題。建立含 STATCOM 的風(fēng)光儲互補(bǔ)系統(tǒng)模型,采用線性自抗擾技術(shù)用于 STATCOM 的控制策略,仿真結(jié)果表明,該控制策略能夠釋放更多的無功功率,改善電壓降落問題。
        關(guān)鍵詞: 風(fēng)光儲互補(bǔ)系統(tǒng);電壓降落;靜止同步補(bǔ)償器;控制策略

        Abstract: Wind power generation and photovoltaic power generation have the same characteristics of being affected by weather change and poor voltage stability. However, STATCOM could dynamically inject reactive power into the wind-solar-storage complementary system to solve the voltage drop problem. This paper constructed a wind-solar-storage complementary system model with STATCOM and used the linear active disturbance rejection technology in the STATCOM control strategy. Simulation results show that the control strategy could release more reactive power and improve the voltage drop problem.
        Key words: wind-solar-storage complementary system; voltage drop; static synchronous compensation( STATCOM); control strategy
