【摘要】：直流斷路器的優(yōu)化配置對提高直流配電網(wǎng)可靠性、降低用戶停電損失具有重要意義。基于最小割集法提出了直流負(fù)荷點區(qū)域劃分方法,建立了計及電力電子設(shè)備功能故障的停電損失費用計算模型。以開關(guān)設(shè)備投資運行費用和停電損失費用之和最低為優(yōu)化目標(biāo),配置斷路器數(shù)目為階段數(shù),配置斷路器位置組合為狀態(tài),針對直流斷路器造價隨技術(shù)發(fā)展下降空間較大的特點,提出了一種考慮價格變化的直流斷路器配置動態(tài)規(guī)劃算法。以手拉手型直流配電網(wǎng)為例進(jìn)行了計算分析,結(jié)果表明該方法能夠?qū)χ绷鲾嗦菲鲀r格進(jìn)行區(qū)間劃分,并得到各區(qū)間所對應(yīng)的最優(yōu)配置方案。
[Abstract]:The optimal configuration of DC circuit breakers is of great significance to improve the reliability of DC distribution network and reduce the power loss of users. Based on the minimum cut set method, a method of dividing DC load points is proposed. A model for calculating the cost of power outage loss considering the functional failure of power electronic equipment is established. With the minimum sum of investment operating cost and outage loss cost of switchgear as the optimization objective, the number of circuit breakers is arranged as the number of stages. With the position combination of circuit breakers as the state, the cost of DC circuit breakers decreases greatly with the development of technology. A dynamic programming algorithm for the configuration of DC circuit breakers considering the change of price is proposed. Taking the hand-held DC distribution network as an example, the results show that the method can divide the prices of DC circuit breakers. The optimal allocation scheme corresponding to each interval is obtained.
