【摘要】：當(dāng)前，配電系統(tǒng)的擴(kuò)建投資大、建設(shè)周期長(zhǎng)以及日益凸顯的峰谷差值，僅僅依靠配電網(wǎng)擴(kuò)容難以滿足快速增長(zhǎng)的負(fù)荷需求。分布式發(fā)電技術(shù)具有高效、靈活、環(huán)保的優(yōu)點(diǎn)，引起了全球范圍內(nèi)的廣泛關(guān)注。同時(shí)，需求側(cè)管理能夠緩解電網(wǎng)短期容量短缺，推遲電網(wǎng)改造投資的目的，因此,在集中式發(fā)電和大電網(wǎng)運(yùn)行的基礎(chǔ)上,大力發(fā)展分布式發(fā)電和需求側(cè)管理技術(shù),建立含有分布式發(fā)電和需求側(cè)響應(yīng)的新型配電網(wǎng)將成為未來智能電網(wǎng)發(fā)展的必然趨勢(shì)。但是,隨著分布式能源和需求側(cè)管理等電網(wǎng)新技術(shù)的應(yīng)用和逐步深入，傳統(tǒng)的配電網(wǎng)規(guī)劃方法面臨著前所未有的挑戰(zhàn)。 本文結(jié)合實(shí)際工程提出了考慮分布式電源和需求側(cè)響應(yīng)的配電網(wǎng)綜合規(guī)劃的方法。首先，考慮分布式電源對(duì)配電網(wǎng)規(guī)劃的影響，在分布式電源個(gè)數(shù)、位置和單個(gè)電源容量均不確定的情況下，通過折算到每年的分布式電源的投資及運(yùn)行費(fèi)用、網(wǎng)損費(fèi)用、引入分布式電源后購電費(fèi)用、環(huán)境效益幾個(gè)方面確定目標(biāo)函數(shù)；其次，在進(jìn)行分布式電源規(guī)劃后，通過可中斷負(fù)荷電價(jià)進(jìn)行需求側(cè)響應(yīng)，把用戶側(cè)資源也引入配電網(wǎng)規(guī)劃模型中實(shí)行聯(lián)合規(guī)劃；最后運(yùn)用Matlab軟件編寫了支持向量機(jī)和粒子群算法的混合智能算法程序，并通過該改進(jìn)的算法對(duì)目標(biāo)函數(shù)進(jìn)行計(jì)算尋優(yōu)，，得到了經(jīng)濟(jì)性和可靠性最優(yōu)的聯(lián)合規(guī)劃方案。 通過對(duì)清新區(qū)某實(shí)際饋線進(jìn)行簡(jiǎn)化處理，得到42節(jié)點(diǎn)配電系統(tǒng)。針對(duì)三種情景下的規(guī)劃方案進(jìn)行經(jīng)濟(jì)性和可靠性指標(biāo)計(jì)算，結(jié)果對(duì)比分析得到含DG及需求側(cè)響應(yīng)的綜合規(guī)劃方案能改善負(fù)荷特性，優(yōu)化電網(wǎng)運(yùn)行，推遲配電網(wǎng)線路擴(kuò)容建設(shè)和帶來一定的環(huán)境效益，為清新區(qū)接入分布式電源和實(shí)施需求側(cè)管理提供指導(dǎo)建議。
[Abstract]:At present, distribution system expansion investment, long construction cycle and increasingly prominent peak and valley difference, only relying on distribution network expansion is difficult to meet the rapid growth of load demand. Distributed generation technology is efficient and flexible. The advantages of environmental protection have attracted worldwide attention. At the same time, demand-side management can alleviate the shortage of short-term capacity of power grid and delay the purpose of investment in power grid transformation. On the basis of centralized generation and large power grid operation, distributed generation and demand-side management technology are developed vigorously. The establishment of a new distribution network with distributed generation and demand-side response will become an inevitable trend in the future smart grid development. However, with the application and gradual deepening of new grid technologies such as distributed energy and demand-side management. The traditional distribution network planning method is facing unprecedented challenges. In this paper, a method of integrated distribution network planning considering distributed generation and demand-side response is proposed. Firstly, considering the influence of distributed generation on distribution network planning, the number of distributed generation is considered. In the case of uncertain position and capacity of a single power supply, by converting to the annual investment and operation costs of distributed power generation, network loss costs, the introduction of distributed power generation after the cost of power purchase. The objective function is determined in several aspects of environmental benefit; Secondly, after the distributed power generation planning, demand side response is carried out through interruptible load price, and the user-side resources are also introduced into the distribution network planning model to implement joint planning. Finally, the hybrid intelligent algorithm program of support vector machine and particle swarm optimization algorithm is written by using Matlab software, and the improved algorithm is used to calculate and optimize the objective function. The optimal joint programming scheme of economy and reliability is obtained. By simplifying a real feeder in Qingxin District, a 42-node distribution system is obtained. The economic and reliability indexes are calculated for the planning scheme under three scenarios. Results the comprehensive planning scheme with DG and demand-side response can improve the load characteristics, optimize the power grid operation, delay the construction of distribution network line expansion and bring certain environmental benefits. To provide guidance suggestions for access to distributed power generation and implementation of demand side management in Qingxin District.
