Scheduling Strategy for “Wind-Network-Vehicle” Joint Accommodation Based on Electric Vehicle Clustering

  • 摘要: 为解决电动汽车的大规模实时优化调度问题,在建立电动汽车状态矩阵的基础上,提出电动汽车状态集群划分新方法。定义功率满意度及时间满意度,加权和为用户满意度,并以经济收益与满意度最大为目标,构造基于电动汽车分群的“风-网-车”实时联合消纳调度模型。针对并网运行的风电场出力与电动汽车负荷不确定性问题,研究可信性理论与模糊机会约束的融合,引入可信性测度指标,对模糊机会约束条件进行清晰化等价处理。最后,采用考虑外点罚函数法并带收缩因子的粒子群优化算法对调度模型进行优化求解,通过算例验证该模型及调度策略的优越性。

     

    Abstract: In order to solve the large-scale real-time optimization scheduling problem of electric vehicles, a new method is proposed for dividing electric vehicles into several state clusters based on establishment of the electric vehicle state matrix. The power satisfaction and time satisfaction are defined in this paper, and their weighted sum is the user’s satisfaction. By taking the maximum economic benefit and satisfaction as the goal, a “wind-network-vehicle” real-time joint accommodation scheduling model is constructed based on the electric vehicle clustering. Aiming at the problem of grid-connected wind farm output and the uncertainty of electric vehicle loads, this paper studies the fusion of credibility theory and fuzzy opportunity constraints, introduces credibility measures, and makes clear and equivalent treatment of fuzzy opportunity constraints. Finally, a particle swarm optimization algorithm with a shrinkage factor considering the outlier penalty function method is used to optimize the scheduling model, and a case is used to verify the superiority of the model and its scheduling strategy.
