摘要
可调负荷、电动汽车等各种负荷侧资源快速发展,对其进行精准调控是目前重要的研究热点.为充分发挥配电网柔性负荷的调节能力,提出一种基于改进交替方向乘子法的配电网柔性负荷分层集群调控方法.首先,采用综合层次聚类算法对柔性负荷进行分层集群;其次,基于纳什谈判理论,将原问题分解为成本最小化和收益分配 2 个子问题,建立配电网柔性负荷集群调控模型;然后,引入自适应变参数加速因子,提出改进的交替方向乘子法;最后,通过模拟算例验证所提方法的有效性.结果表明,所提方法能够有效实现大规模柔性负荷接入情况下的集群调控,收敛性能较常规方法有所提高.
Abstract
With the rapid development of various load side resources such as adjustable loads and electric vehicles,how to accurately regulate them has become an important research point.In order to give full play to the regulation ability of flexible loads in distribution networks,a hierarchical cluster regulation method for flexible loads in distribution networks based on improved alternating direction multiplier method is proposed.Firstly,the flexible loads are clustered hierarchically using the BIRCH clustering algorithm.Secondly,based on Nash negotiation theory,the original problem is decomposed into two sub problems:cost minimization and revenue allocation,and a flexible load cluster regulation model for distribution networks is established.Then,an improved alternating direction multiplier method is proposed by introducing an adaptive variable parameter acceleration factor.Finally,a simulation example is used to verify the effectiveness of the proposed method.The results show that the proposed method can effectively achieve cluster regulation under access of large-scale flexible loads,and its convergence performance is better than the conventional methods.
