考虑电力负荷需求和分布式电源不确定性的配电网重构OA北大核心CSTPCD

Distribution network reconfiguration considering power load demand and distributed power source uncertainty

中文摘要英文摘要

随着可再生能源和可变负荷在配电系统中比例的逐步提高,配电网中电力流向的不确定性对最优网络拓扑结构的影响越来越显著.由于分布式发电和需求响应受时间因素影响,按单时段建模所得到的拓扑结构在一天中的不同时段难以达到最优.为解决这种不确定因素的影响,文章提出了一种基于二阶锥优化的配电网重构模型,进行计及需求响应的多时段潮流分析.基于实际配网系统所存在的"源-储-荷"结构,建立了以网络运行成本和开关运行成本为目标的约束条件,利用二阶锥松弛将非凸形式搜索空间转化为凸可行域,从而进行快速求解.在改进的IEEE 33节点配电网上进行测试分析,结果表明,文章提出的方法比传统方法具有更高的准确性和更快的求解速度.

As the proportion of renewable energy and variable loads in the distribution system gradually increases,the uncertainty of power flow in the distribution network will affect the optimal network topology.Since distributed generation and demand response are affected by the time factor,the topology obtained by modeling at a single time period is difficult to be optimized at different times of the day.To address this uncertainty,this paper proposes a second-order cone optimization-based distribution network reconfiguration model for multitemporal tidal flow analysis for billing and demand response.By considering the"source-storage-load"structure of the actual distribution system,an optimization problem with the objectives of network operation cost and switching operation cost is established,and the second-order cone relaxation is used to transform the nonconvex search space into a convex feasible domain for fast solution.Experimental results on an improved IEEE 33 node distribution network show the superiority of the proposed method over traditional methods in terms of accuracy and solution speed.
