【摘要】：電力系統(tǒng)在近幾十年來飛速發(fā)展,各地區(qū)電網(wǎng)相互聯(lián)同,電網(wǎng)規(guī)模日益擴(kuò)大。電網(wǎng)負(fù)荷變化波動(dòng)較大、負(fù)荷峰谷差值較大等問題都對(duì)電力系統(tǒng)安全經(jīng)濟(jì)運(yùn)行提出了更高的要求。本篇論文主要結(jié)合稀疏矩陣技術(shù)利用經(jīng)典法對(duì)電力系統(tǒng)有功優(yōu)化中負(fù)荷經(jīng)濟(jì)分配問題展開研究,進(jìn)行了理論分析、通過計(jì)算機(jī)編程來用算例對(duì)本算法進(jìn)行驗(yàn)證。文章系統(tǒng)的對(duì)網(wǎng)絡(luò)潮流計(jì)算進(jìn)行了推導(dǎo)分析,基于稀疏矩陣技術(shù)對(duì)節(jié)點(diǎn)導(dǎo)納矩陣提出了新的存貯方式、對(duì)求解阻抗矩陣的過程以及對(duì)牛頓法潮流中雅克比矩陣形成過程提出了新改進(jìn)。在計(jì)算時(shí)間以及儲(chǔ)存空間上得到了極大的優(yōu)化,并且基于稀疏矩陣技術(shù)對(duì)牛頓拉夫遜和直流潮流算法分別提出了簡(jiǎn)化快速求解方法并依次進(jìn)行驗(yàn)證。文章的最后建立了計(jì)及網(wǎng)損的有功負(fù)荷經(jīng)濟(jì)分配研究模型,考慮系統(tǒng)網(wǎng)損并對(duì)現(xiàn)有的幾種有功網(wǎng)損微增率的算法進(jìn)行推導(dǎo)改進(jìn)和計(jì)算比較,并將改進(jìn)后的算法應(yīng)用到電力系統(tǒng)負(fù)荷經(jīng)濟(jì)分配中。文章的最后就是通過對(duì)IEEE-5節(jié)點(diǎn)、IEEE-14節(jié)點(diǎn)算例對(duì)改進(jìn)經(jīng)典法進(jìn)行了驗(yàn)證和比較。
[Abstract]:With the rapid development of power system in recent decades, the scale of power grid is expanding day by day.Many problems such as large fluctuation of load and large difference between peak and valley put forward higher requirements for the safe and economical operation of power system.This paper mainly uses sparse matrix technology to study the load economic distribution problem in power system active power optimization using classical method, and carries out theoretical analysis, and verifies this algorithm by computer programming examples.In this paper, the network power flow calculation is deduced and analyzed systematically, and a new storage method of node admittance matrix based on sparse matrix technique is proposed.The process of solving impedance matrix and the forming process of Jacobian matrix in Newton power flow are proposed.The computation time and storage space are optimized greatly. Based on sparse matrix technique, a simplified and fast algorithm for Newton Raphson and DC power flow is proposed and verified in turn.At the end of the paper, the economic distribution model of active power load considering network loss is established. Considering the system network loss, several existing algorithms are deduced and improved, and the calculation results are compared.The improved algorithm is applied to load economic distribution of power system.At the end of the paper, the improved classical method is verified and compared with the IEEE-5 node IEEE-14 node.
