摘要为加快配电网故障恢复速度,并在恢复过程中考虑各个参与主体的利益,提出一种基于博弈思想的主动配电网故障灵活分层恢复策略,并建立一种基于博弈思想的包含参与层和均衡层的主动配电网故障灵活分层恢复模型。根据故障恢复的参与主体,将参与层又划分为负荷层、联络开关层和分段开关层三个子层次。在负荷层,提出基于电量拍卖模型的切负荷策略;在联络开关层,以恢复可能性指标值最大为目标进行联络开关和分布式电源的联盟;在分段开关层,以网损最小为目标调用改进的蚁群算法进行寻优。在均衡层,将各个子层的策略进行组合,以实现各参与恢复主体总收益最优的目标。基于上述分层策略构建的多代理恢复系统和VIKOR算法进行合作博弈决策求得纳什均衡解。根据故障失电场景的不同,灵活调用相关的参与层进行恢复方案的制定,降低恢复方案的冗余,提高计算的快速性。最后,通过IEEE 69节点算例验证了所提策略的灵活性和有效性。

Abstract：In order to accelerate the recovery calculation speed of the distribution network and consider the interests of all decision-makers, a flexible layered restoration strategy of active distribution network based on game theory is proposed, and the related model is also established including a participant layer and a Nash equilibrium layer. According to the main body involved in fault recovery, the participant layer is divided into three sub-layers: a load layer, a tie switches layer, and a sectional switches layer. At the load layer, a load shedding strategy based on the power auction model is proposed. At the tie switches layer, a coalition of tie switches and distributed generations is carried out to maximize the restoration possibility index. At the sectional switches layer, the improved ant colony algorithm is used to minimize the network loss. In the Nash equilibrium layer, the strategies of each sub-layer are combined to maximize the total interest of every participant. Based on the above mentioned layered strategy and VIKOR (VlseKriterijumska Optimizacija I Kompromisno Resenje) algorithm, a multi-agent recovery system is used to determine the Nash equilibrium solution. According to different fault scenarios, related layers are invoked flexibly to make restoration schemes, which reduces the redundancy of restoration schemes and improves the speed of calculation. Finally, IEEE 69-node system has verified the proposed strategy.
