摘要

提出了一种考虑冷负荷冲击影响的电动汽车辅助孤岛复电方法。该方法中，首先提出对任意给定的冷负荷变化模型和电动汽车放电衰减模型进行离散化，进而在混合整数线性规划的框架下，以缺失电量最小化为目标，建立了考虑离散冷负荷模型和电动汽车放电模型的最优孤岛复电规划方法。所提方法在IEEE RBTS-BUS6系统上进行了测试，分析了冷负荷冲击对孤岛供电的影响，以及电动汽车放电对增强孤岛供电恢复的辅助作用。同时，研究了电动汽车场总放电功率利用率和失电负荷能量恢复率之间的量化关系。

Abstract

A method of restoring electric power supply for isolated island with the auxiliary of electric vehicles is proposed considering cooling load impact. Firstly a discretization methodology is used to deal with any given dynamic cooling load models and discharge attenuation models of electric vehicles. Then

under the framework of linear programming of mixed integers

a planning method of restoring electric power supply for optimal isolated island is proposed

which aims to maximize the recovered energy of interrupted end-users in terms of discretized cooling load models and discharge models of electric vehicles. The proposed method is tested on the IEEE RBTS-BUS6 system

and the analyses are made on the impacts of cooling load on energy restoration of isolated island

and the assistant effect of electric vehicles on restoring electric power supply for isolated island. Moreover

the especial quantitative relationship is studied between the utilization rate of total discharging power of an electric vehicle parking lot and the rate of restored energy with respect to the total lost energy.
