Research on electric vehicle consumption wind power in aggregator mode

电动汽车协同新能源共同规划为新能源的充分利用带来新机遇。文章研究了聚合商模式下的电动汽车消纳弃风的调度策略;设计了聚合商、电动汽车车主、风电场三方共同获利的合作方法;提出了包含电动汽车的可信度和剩余电量的电动汽车可调度潜力评估方法;对参与聚合商充放电控制的电动汽车进行排序,建立了考虑风电出力不确定性的聚合商协同风电场消纳弃风的优化调度模型。该模型以聚合商收益最高为目标函数,在分析购电分时电价、电动汽车充电分时电价的基础上,结合各类基础参数对模型进行求解。文章以上海某区域为研究对象进行算例仿真,验证了所提策略既能使三方获利,又能取得消纳部分弃风和减轻电网负荷高峰的效果。

The joint planning of electric vehicles and new energy brings new opportunities for the full utilization of new energy. This paper studies the dispatching strategy of electric vehicles in the agglomeration mode to eliminate wind and abandon winds;designs a cooperative method for the agglomeration of aggregators, electric vehicle owners, and wind farms;and proposes an electric vehicle that includes the credit and remaining power of electric vehicles. The schedulable potential assessment method is used to classify the electric vehicles participating in the charge and discharge control of the aggregator, and an optimal scheduling model for the agglomeration of wind farms considering the wind power output uncertainty is established. The model takes the highest income of the aggregator as the objective function. Based on the analysis of the time-of-use electricity price and the electric vehicle charging time-sharing electricity price, the model is solved by combining various basic parameters. The paper uses a certain area of Shanghai as the research object to simulate the example and verifies that the proposed strategy can not only benefit the three parties but also achieve the effect of eliminating some of the wind and reducing the peak load of the power grid.
