随着新能源大量接入配电网,新能源出力的不确定性和波动性给配电网规划带来了巨大挑战.在配电网规划中综合考虑源网荷储,可减少新能源不确定性和波动性对规划结果的影响.提出了一种考虑动态重构和智能软开关接入的配电网源网荷储联合规划方法.首先,根据密度峰值聚类的思想提出了基于密度峰值改进的近邻传播聚类算法,对风光荷联合场景进行聚类获得典型日曲线.然后,以规划总费用最小为目标函数,建立了考虑动态重构和智能软开关接入的配电网源网荷储联合规划模型,并基于二阶锥理论,将原非凸非线性规划模型转化为混合整数二阶锥规划模型.最后,在Portugal 54算例上进行仿真验证,证明了所提模型和方法的有效性.
Joint Planning of Source-Network-Load-Storage in Distribution Network Considering Dynamic Reconfiguration and Intelligent Soft Open Point
With a large number of new energy being connected to the distribution network,the uncertainty and volatility of new energy output have brought great challenges to the distribution network planning.The impact of uncertainty and volatility of new energy on planning results can be reduced by comprehensively considering the source-network-load-storage.Based on this,a joint planning method of source-network-load-storage in distribution network considering dynamic reconfiguration and intelligent soft open point is proposed.First of all,according to the idea of density peak clustering,an improved affinity propagation clustering algorithm based on the density peak is proposed to cluster the combined scenes of wind power,photovoltaic and load to obtain the typical daily curve.Then,taking the minimum of the total planning cost as the objective function,a joint planning model of source-network-load-storage in distribution network considering dynamic reconfiguration and intelligent soft open point is established.Based on the second-order cone theory,the original non convex nonlinear planning model is transformed into a mixed integer second-order cone planning model.Finally,the validity of the proposed model and method is verified by simulation on the Portugal 54 numerical example.
