电动汽车的主动管理及其对配网的影响建模

随着智能配电网的快速发展,大量分布式能源的接入使得配电网面临一些新的挑战。文章首先介绍了主动配电网的含义和结构,然后针对电动汽车作为主动负荷的特点,提出了以电动汽车整合实体为中心的分层控制结构。基于电动汽车及其主动管理对电网稳态运行的影响和效益分析,提出针对不同充电策略情况下评估电动汽车对低压和中压配电网影响的方法,建立相应的数学模型和算法流程,并进行了相关的仿真实验和结果分析,为将来配电网中电动汽车的主动管理与控制提供了理论基础。

Active management of electric vehicles and modeling its impact on distribution network

With the rapid development of smart distribution network, the access of a large number of distributed gen-eration makes the distribution network face some new challenges.In this paper, the meaning and structure of the ac-tive distribution network are introduced firstly.Then, for electric vehicles as the active load, the hierarchical control structure based on entity-centric is proposed to integrate electric vehicles.Based on the analysis of the effect and ben-efit of electric vehicles and its active management on the steady operation of power grid, the method for evaluating the impact of electric vehicles on the low voltage and medium voltage distribution network under different charging strate-gies is proposed, and the corresponding mathematical model and algorithm flow are given.The related simulation ex-periments and results analysis are also carried out.It provides a theoretical basis for the active management and con-trol of electric vehicles in the distribution network.
