分布式电源与电动汽车充电站共同接入配电网,对配电网规划和运行具有重要的影响。提出一种综合协调规划方法,该方法能够实现分布式电源选址定容、充电站位置及容量、配电网架建设和改造的综合优化规划。考虑风光资源和负荷的随机波动性,以配电系统投资、运行维护和环境成本的随机期望值最小为目标,建立了含分布式电源与充电站的配电网协调规划模型,采用改进遗传算法进行求解。以一个待扩展的辐射状配电网络为例,仿真计算结果表明,对含分布式电源与充电站的配电网进行综合协调规划,能够提高电网的经济和环境效益,得到的规划方案更为合理。

The jointly accessing of distributed generation and electric vehicle charging stations to the distribution network has a significant impact on operation and planning. A comprehensive coordinated planning method is proposed, with which the optimized synthetic planning can be realized including sitting and sizing of distributed generation, position and capacity of charging station, and construction and retrofit of distribution network. Considering environmental factors, randomness of resources and load, the coordinated programming model of distribution network is presented. The objective is to minimize stochastic expected value of costs about investment, operation, maintenance and environment, and the model is solved by improved genetic algorithm. A radial distribution network for expansion is selected as the example. Simulation results show that the economic and environment benefits are effectively improved by the coordinated planning, and planning scheme obtained is more reasonable.
