针对目前电动汽车的快速普及与发展以及环境污染严重、能源急剧紧缺等问题,研究电动汽车与分布式电源接入配电网,联合参与配电网的优化调度对配电网所产生的影响。首先建立了电动汽车接入配电网的充放电模型,得到电动汽车接入后配电网的负荷曲线;其次,以发电成本最小化为优化目标建立配电网优化调度模型,通过粒子群优化算法对模型求解,最后,分别计算优化调度前后配电网各项特性指标,进而得出结论。
In view of the rapid popularization and development of electric vehicles as well as serious environmental pollution and drastic energy shortage, this paper studies the impact of electric vehicles and distributed generation access distribution networks, and the joint participation of distribution networks in optimal distribution on distribution networks. Firstly, the charge and discharge model of EV access distribution network is established, and the load curve of EV distribution network is obtained. Secondly, the optimization scheduling model of distribution network is established with the goal of minimizing generation cost. By using Particle Swarm Optimization Algorithm to solve the model. Finally, calculate the various characteristics of distribution network before and after optimal scheduling indicators, and then draw conclusions.
