摘要
配电网的无功功率流动存在不合理性,影响了电网电压的稳定性.通过构建多目标优化数学模型对状态变量控制装置的位置和数据进行计算,同时增设无功补偿点并基于马尔可夫链蒙特卡罗方法对增设的无功补偿点进行无功变量编码的约束优化,以此实现对配电网综合电压无功优化的高效与精准控制.在算例分析中,经过无功优化后的节点电压波动值最大只有0.1455p.u..
Abstract
The unreasonable reactive power flow of distribution network affects the voltage stability.By constructing a multi-objective optimization mathematical model,the position and data of the state variable control device were calculated,and reactive power compensation points were added and constrained optimization of reactive power variable coding was car-ried out on the additional reactive power compensation points based on Markov chain Monte Carlo method,so as to achieve efficient and accurate reactive power compensation and bi-level voltage management.In case calculation analysis,the pro-posed reactive power compensation method achieved node voltage fluctuation of lower than 0.1455p.u..
