含分布式电源的配电网检修计划优化方法研究

Research on Optimization Method for Maintenance Plan of Distribution Network Containing Distributed Power Generation

针对可再生能源为基础的分布式能源大量接入配电网,对配电网的检修计划造成一定影响的问题,建立了一种考虑配电网分布式电源接入的配电网检修计划优化模型,以IEEE33节点配电网系统为例进行算例分析。数值结果表明,该优化模型能够充分利用分布式电源的发电能力,与联络开关的倒闸操作相配合,有效减少配电网的检修总费用,提高电力系统运行管理水平,进而保证电力系统的正常运行。

Distributed energy based on renewable energy has been connected to the distribution network in large numbers in recent years,which has a certain impact on the maintenance plan of the distribution network.This paper considers the access of distributed energy in the distribution network,and establishes an optimal model for the maintenance plan of the distribution network.Take the IEEE33-bus distribution network system as an example to analyze the calculation example.The numerical results show that the optimal model can make full use of the power generation capacity of distributed energy,cooperate with the switching operation of the tie switch,effectively reduce the total maintenance cost of the distribution network,improve the operation and management level of the power system,and ensure the normal operation of the power system.
