摘要: 考虑电动汽车、空调负荷等柔性负荷的无序接入对电网造成的不利影响,提出一种计及电动汽车供电资源态势分析的台区负荷弹性优化调度方法。首先,对电动汽车的充电需求进行概率预测,通过量化分析电动汽车负荷的特性指标,提出了台区电动汽车供电资源的态势感知模型,通过集成学习算法训练进行供电资源态势评估;接着,基于供电资源态势感知情况提出对电动汽车充电需求进行弹性伸缩的优化调度策略,将电动汽车充电需求与空调负荷削减量作为控制量,建立带弹性约束的多目标调度计划优化模型,采用改进多目标粒子群算法求解得到优化调度计划;最后,通过台区算例分析验证了所提优化调度方法能实现对电网负荷的削峰填谷,协调解决柔性负荷需求与资源闲置状态下存在的冲突,对电动汽车充电和空调用电负荷进行有序调度,以实现供电资源利用率最大化。

Abstract: Considering the adverse impact of the disorderly access of flexible loads such as electric vehicles (EVs) and air conditioning loads on the power grid, an elastic optimal scheduling method for load in supply region is proposed, which takes into account the situation analysis of EV power supply resources. Firstly, the probability prediction of the charging demand of EVs is carried out. Through quantitative analysis of the characteristic indicators of EV loads, a situation awareness model for regional EV power supply resources is proposed, and the situation assessment of power supply resources is performed through  training of integrated learning algorithms. Then, according to the situational awareness result, this paper proposes an optimal scheduling strategy that flexibly controlling the charging demand of EVs. It takes the charging demand of EVs and the reduction amount of air conditioning load as control amounts, establishes a multi-objective scheduling optimization model with elastic constraints, and improves multi-objective particle swarm optimization. The algorithm is solved to obtain the optimal scheduling plan. Finally, the analysis of regional examples verifies that the proposed optimal scheduling method can achieve peak regulation of the power load, coordinately resolve the conflicts between the demand for flexible loads and idle resources, orderly dispatch   EVs charging  and air-conditioning   load to maximize the utilization of power supply resources.

Key words: electric vehicle charging requirements, situation awareness of power supply resources, integrated learning, flexible optimal scheduling
