摘要
建立了电动汽车区间负荷模型和充换放储一体化电站(简称一体站)区间负荷紧急支撑模型,提出一体站区间负荷紧急支撑策略及其孤岛区间负荷供电范围划分策略。基于区间理论分析,以系统孤岛负荷、开关动作次数和网损分别作为不同层的优化目标,建立主动配电网故障恢复多层优化区间模型。提出混沌模拟退火帝国竞争算法对故障恢复区间模型进行优化,并提出基于仿射数的区间Dist-Flow法用于潮流计算。算例结果表明所提方法快速、有效。
An interval load model of electric vehicles and an emergency support model of interval load for a charging-swappingdischarging-storage integrated power station(CSDSIS)are established.An emergency support strategy of interval load and an island partition strategy for power supply range of interval load for a CSDSIS are proposed.Based on the analysis of interval theory,a multi-layer optimization interval model of fault recovery for active distribution network(ADN)is established by taking the island load of system,times of breaker switching and power loss as the optimization objectives,respectively.Chaotic simulated annealing imperialist competitive algorithm is proposed to optimize the fault recovery interval model,and an interval Dist-Flow method based on affine number is proposed for power flow calculation.Results of the example show that the proposed method is fast and effective.
