    摘要:

    为提高供电恢复效果,更好地应对当前有源配电网信息-物理耦合程度不断加深的形势,提出了一种考虑信息流、能量流、业务流多流融合以及智能软开关(soft open point,SOP)作用的孤岛划分算法,基于该算法实现供电恢复策略。首先,为保证负荷的可靠恢复,该策略深入研究信息-物理耦合并建模,对节点信息重要度排序,讨论其对负荷恢复的影响;其次,构建了SOP的稳态模型,分析了SOP的工作原理及控制模式;接着,为了更大程度、更加灵活地恢复负荷,考虑SOP的作用,建立考虑光伏时变性及负荷运行特性的有源配电网孤岛划分模型;最后,算例仿真验证所提策略的有效性。

    Abstract:

    In order to improve the power supply recovery effect and better cope with the situation of the deepening of the information-physical coupling degree of active distribution network, an island partitioning algorithm considering the multi-flow fusion of information flow, energy flow, service flow and the function of intelligent open point (SOP) is proposed. First, in order to ensure reliable load recovery, the strategy deeply studies the information-physical coupling and models it, ranking the importance of node information, and discussing its impact on load recovery. Secondly, the steady-state model of SOP is constructed, and the working principle and control mode of SOP are analyzed. Then, in order to restore the load to a greater degree and more flexibly, considering the role of SOP, the active distribution network island division model considering the PV time variability and load operation characteristics is established. Finally, a simulation example is given to verify the effectiveness of the proposed strategy.
