【摘要】：電力系統(tǒng)負(fù)荷需求的增長(zhǎng),電網(wǎng)規(guī)模的不斷擴(kuò)大,使得系統(tǒng)短路電流水平不斷升高,影響了電網(wǎng)運(yùn)行的安全穩(wěn)定性。系統(tǒng)短路電流水平與電網(wǎng)結(jié)構(gòu)息息相關(guān),而傳統(tǒng)的輸電網(wǎng)規(guī)劃通常在網(wǎng)架確定后對(duì)短路電流進(jìn)行校驗(yàn),忽略了短路電流對(duì)電網(wǎng)規(guī)劃的重要導(dǎo)向作用,也未能從電網(wǎng)規(guī)劃層面考慮短路電流限制措施的應(yīng)用。因此,如何協(xié)調(diào)輸電網(wǎng)規(guī)劃建設(shè)與限流措施的應(yīng)用、合理平衡輸電容量和短路容量具有重要研究意義�；�于上述背景,本文重點(diǎn)研究了考慮短路電流限制的輸電網(wǎng)擴(kuò)展規(guī)劃方法,主要完成以下工作:(1)調(diào)研了國(guó)內(nèi)外關(guān)于輸電網(wǎng)規(guī)劃、短路電流限制措施應(yīng)用、短路電流計(jì)算標(biāo)準(zhǔn)等方面的研究現(xiàn)狀;(2)建立了以限流措施應(yīng)用成本最小為目標(biāo),計(jì)及含限流措施的潮流平衡約束、節(jié)點(diǎn)電壓約束、線路路潮流約束和限流措施應(yīng)用約束的電網(wǎng)典型限流措施優(yōu)化配置模型,并提出基于篩選策略的改進(jìn)離散粒子群算法進(jìn)行求解;(3)基于雙層規(guī)劃理論,將電網(wǎng)典型限流措施引入輸電網(wǎng)規(guī)劃當(dāng)中,分別選取線路開(kāi)斷措施和加裝限流電抗器措施,建立了考慮線路開(kāi)斷限流的輸電網(wǎng)雙層擴(kuò)展規(guī)劃模型和考慮限流電抗器優(yōu)化配置的輸電網(wǎng)雙層擴(kuò)展規(guī)劃模型,并利用自適應(yīng)遺傳算法、改進(jìn)離散粒子群算法求解上、下層規(guī)劃問(wèn)題。(4)以新英格蘭39節(jié)點(diǎn)系統(tǒng)為例驗(yàn)證了電網(wǎng)典型限流措施優(yōu)化配置模型及其求解算法的有效性,以Garver 6節(jié)點(diǎn)系統(tǒng)驗(yàn)證了考慮線路開(kāi)斷限流的輸電網(wǎng)雙層擴(kuò)展規(guī)劃模型的合理性,以18節(jié)點(diǎn)系統(tǒng)和基于18節(jié)點(diǎn)系統(tǒng)擴(kuò)展的19節(jié)點(diǎn)系統(tǒng)驗(yàn)證了考慮限流電抗器優(yōu)化配置的輸電網(wǎng)雙層擴(kuò)展規(guī)劃模型的合理性。
[Abstract]:With the increase of power system load demand and the expansion of power network scale, the level of short-circuit current is increasing, which affects the safety and stability of power system operation. The level of system short-circuit current is closely related to the structure of power network. However, the traditional transmission network planning usually verifies the short-circuit current after the grid frame is determined, neglecting the important guiding role of short-circuit current to the power network planning. Also failed to consider the application of short-circuit current restriction measures from the power network planning level. Therefore, how to coordinate the transmission network planning and construction and the application of current limiting measures. Reasonable balance of transmission capacity and short-circuit capacity is of great significance. Based on the above background, this paper focuses on the method of transmission network expansion planning considering short-circuit current constraints. The main work is as follows: 1) the research status of transmission network planning, application of short-circuit current limitation measures, short-circuit current calculation standard and so on has been investigated. 2) taking the minimum application cost of the current limiting measures as the goal, considering the power flow balance constraints and the node voltage constraints of the current limiting measures. The optimal configuration model of typical current limiting measures for power network with line power flow constraints and current limiting measures is proposed, and an improved discrete particle swarm optimization algorithm based on screening strategy is proposed to solve the problem. Based on the bilevel programming theory, typical current limiting measures are introduced into transmission network planning, and line breaking measures and additional current limiting reactor measures are selected respectively. The bilevel expansion programming model of transmission network and the bilevel expansion programming model of transmission network considering the optimal configuration of current limiting reactor are established, and the adaptive genetic algorithm is used. Improved discrete Particle Swarm Optimization (DPSO), the lower layer programming problem. 4) take the New England 39-bus system as an example to verify the effectiveness of the optimal configuration model of typical current limiting measures and its algorithm. The Garver 6-bus system is used to verify the rationality of the bilevel expansion programming model of transmission network considering the line breaking and limiting current. Based on the 18-bus system and the 19-bus system based on the 18-bus system, the rationality of the bilevel expansion programming model of the transmission network considering the optimal configuration of the limiting reactor is verified.
