    摘要:

    配电网中分布式新能源、可控负荷等柔性资源参与电网需求响应已成为新型电力系统削峰填谷的重要手段,而如何考虑用户响应度和平衡多主体利益十分关键。为此,文中首先建立用户响应度的模糊控制模型,并给出考虑用户响应度模糊性的供电方、负荷聚合商、用户等多主体需求响应参与方效益函数模型;进而以日负荷曲线偏差最小和系统成本最小为优化目标,上层优化采用供电方最优需求响应方案,下层优化在供电方及负荷聚合商之间求得最优任务分配,从而建立供电方、负荷聚合商、用户等多主体协同需求响应双层模型,并提出基于Stackelberg博弈理论和k-means聚类算法的求解方法;最后以某地区历史数据进行模拟仿真。结果表明文中模型在考虑用户响应度和协同多主体利益下能有效筛选优质需求响应资源,平抑负荷波动。

    Abstract:

    In the distribution network,the participation of flexible resources such as distributed new energy and controllable load in demand response has become an important measure of load adjusting in the new power system. How to consider the uncertainty of user responsiveness and balance the interests of multiple participants is very critical. In this paper,the fuzzy control model of user responsiveness is established firstly,and the benefit function model of multi-agent demand response participants such as power supplier,load aggregator and user is given considering the fuzziness of user responsiveness. Furthermore,with the objectives of minimizing the deviation of daily load curve and minimizing the system cost,the upper optimization adopts the optimal demand response scheme of the power supplier. The lower optimization obtains the best task allocation between the power supplier and the load aggregator,so as to establish the two-layer model of multi-agent collaborative demand response of the power supplier,the load aggregator and the user. A solution method based on Stackelberg game theory and k-means clustering algorithm is proposed. Finally,the simulation results of historical data in an area show that the model can effectively screen high-quality demand response resources to suppress load fluctuation under the consideration of user responsiveness and collaborative of multi-agent interests.
