【摘要】：近年來微電網(wǎng)大力發(fā)展,由其為子單元的多微網(wǎng)(multi-microgrids,MMGs)漸成為一種新型電網(wǎng).作為結(jié)構(gòu)及控制模式更加復(fù)雜的微電網(wǎng)群落,研究安全有效地黑啟動以進(jìn)入正常運(yùn)行狀態(tài)對提高供電可靠性具有重要意義.在分析含單三相復(fù)合混聯(lián)的多微網(wǎng)結(jié)構(gòu)及控制系統(tǒng)基礎(chǔ)上,為使主電源高效運(yùn)行,提出一種考慮三相不平衡度約束的多微電網(wǎng)黑啟動策略,考慮源荷網(wǎng)條件選擇最優(yōu)的儲能系統(tǒng)作為黑啟動主電源,以先獨(dú)立分散恢復(fù)再集中協(xié)調(diào)恢復(fù)的方式實現(xiàn)多微網(wǎng)的源荷網(wǎng)恢復(fù).所提策略經(jīng)驗證有效可靠,可為多微網(wǎng)黑啟動恢復(fù)提供一定的借鑒意義.
[Abstract]:With the rapid development of micro-grid in recent years, multi-micro-grid (multi-microgrids,MMGs), which is a sub-unit, has gradually become a new type of power grid. As a microgrid community with more complex structure and control mode, it is of great significance to study the safe and effective black start-up to enter the normal operation state to improve the reliability of power supply. Based on the analysis of the multi-micro-grid structure and control system with single-phase and three-phase hybrid connection, a black start-up strategy for multi-microgrid considering the constraint of three-phase unbalance is proposed in order to make the main power supply run efficiently. Considering the source load condition, the optimal energy storage system is chosen as the black start main power supply, and the source load recovery of the multi-microgrid is realized by the way of independent decentralized recovery and centralized coordinated recovery. The empirical evidence of the proposed strategy is effective and reliable, which can be used for reference for the start-up recovery of multi-microgrid black.
