基于博弈思想的需求响应视角下的主动配电网故障恢复

Active distribution network fault restoration based on game theory in demand response perspective

为实现主动配电网故障后失电负荷的最大限度恢复,并考虑供电侧与用户侧利益均衡,本文基于博弈的思想,提出需求响应视角下的主动配电网故障恢复策略。在需求响应视角下,供电侧和用户侧建立非合作动态博弈模型优化故障时的峰谷分时电价,抑制高峰负荷需求,减少用电高峰时故障恢复的压力。在主动配电网故障恢复中,基于优化后的负荷曲线,供电侧和用户侧建立合作博弈模型,双方以共同的收益函数作为目标,利用馈线、电动汽车、分布式电源和可控负荷进行协同恢复。分别采用逆向回归算法和改进的蚁群算法求解以上两个博弈模型。本文以IEEE33节点模型和某实际配电网为例,分别对小面积失电和大面积失电情况进行故障恢复求解,验证了本文所提策略的有效性。

In order to maximize the recovery of the load loss after the failure of the active distribution network and coordinate the common interests of supply side and user side,based on game theory,a fault recovery strategy in demand response perspective is proposed.In the perspective of demand response,non-cooperation dynamic game is built between supply side and user side to optimize the peak-valley time-of-use price in the fault period,restrain load demand and reduce the pressure of the fault recovery in the peak period.In the restoration of active distributed network,based on the optimized load curve,cooperation dynamic game is built between supply side and user side,with the object of both common benefits of collaborated restoration scheme of feeder,electric vehicle,distributed generation and controllable load.The inverse regression algorithm and improved ant algorithm are used to solve both games above.This paper takes IEEE33 node model and actual distribution network as examples to carry out service restoration in both small and large outage area,and the effectiveness of the proposed strategy is verified.
