摘要:
提出了 一种兼顾径向功率分配系统(RDS)的可靠性和效率的优化方案,目的是在网络重构 (DNR)的过程中使有功功率的损耗降低到最小.本文实质上是基于改进后遗传算法的网络分支故障分 析,即在暂态过程中重点分析保护系统对故障和恢复系统的响应.具体方法是首先采用基于分支可靠性 的非连续蒙特卡罗仿真方法对网络结构的可靠性进行预测,然后利用遗传算法,进行可实现的结构重构 和高效搜索.此外,本文在无投资的情况下分析了 RDS,将这种算法应用在一个69条线路的网络上,实 验结果证明了改进遗传算法的优越性.
Abstract:
This study focused on an optimization method that combined simultaneously the reliability and the efficiency of radial power distribution systems ( RDS) , minimized active energy losses, through a process of network reconfiguration. The study based on the failure analysis on network branches, with a special concern on the protection system response to faults and the service restoration procedures, in the emergency state. A non-sequential Monte Carlo simulation based on the branch reliability was used to evaluate reliability of the network configurations. Due to a large number of possible configurations and the need of an effcient search, the optimization was made through an improved genetic algorithm (IGA) . In a first step, the method analyed the RDS considering the absence of investment, and in a second step, the possibility of placing a limited number of new tie-switches in certain branches, according to the definitions made by a decision maker. The effectiveness of the proposed methodology was demonstrated through the analysis of a 69 bus RDS and by comparison against other reported methodologies.
