【摘要】：近年来微电网大力发展,由其为子单元的多微网(multi-microgrids,MMGs)渐成为一种新型电网.作为结构及控制模式更加复杂的微电网群落,研究安全有效地黑启动以进入正常运行状态对提高供电可靠性具有重要意义.在分析含单三相复合混联的多微网结构及控制系统基础上,为使主电源高效运行,提出一种考虑三相不平衡度约束的多微电网黑启动策略,考虑源荷网条件选择最优的储能系统作为黑启动主电源,以先独立分散恢复再集中协调恢复的方式实现多微网的源荷网恢复.所提策略经验证有效可靠,可为多微网黑启动恢复提供一定的借鉴意义.
[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.
