電力市場的輸電阻塞管理
摘要
本文取材選自2004年全國大學(xué)生數(shù)學(xué)建模競賽B題，采用兩種方法研究電力市場的輸電阻塞管理問題，并通過建立相應(yīng)的模型進(jìn)行求解。
本論文分為兩大部分。第1部分是基于經(jīng)濟(jì)調(diào)度的阻塞管理方法。分4個問題來說明，問題1我們采用多元線性回歸方法求出了線路有功潮流相關(guān)各機(jī)組的出力表達(dá)式；問題2中，根據(jù)市場交易規(guī)則，本著安全、簡明、合理和公平的原則提出了兩種計(jì)算阻塞費(fèi)用的規(guī)則；針對問題3，我們遵循電力市場交易原則，對給定的負(fù)荷要求制定出力預(yù)案；問題4中，根據(jù)預(yù)案檢驗(yàn)是否出現(xiàn)阻塞，按步驟提出了解決阻塞管理的.規(guī)劃模型。模型采用MATLAB中的單目標(biāo)規(guī)劃函數(shù)linprog和多目標(biāo)規(guī)劃函數(shù)fgoalattain進(jìn)行求解。
第2部分是基于最優(yōu)潮流的阻塞管理方法。阻塞管理模型是在雙邊交易合同市場的條件下建立的，借助于最優(yōu)潮流這個工具，根據(jù)市場報(bào)價調(diào)整實(shí)時平衡市場的電廠出力，在必要時可通過競價手段削減某些雙邊合同量，目標(biāo)函數(shù)為調(diào)整費(fèi)用最小，并且采用5節(jié)點(diǎn)模擬電力系統(tǒng)對該模型進(jìn)行了檢測。
關(guān)鍵詞：輸電阻塞管理；linprog；fgoalattain；經(jīng)濟(jì)調(diào)度；最優(yōu)潮流。
Abstract
The paper gets material from the test B in the national university students mathematics setting up mold contest on 2004. We studies the problem of transmission congestion management on the electric power market, and built up the homologous model to solve.
This paper is divided two parts. The first part is based upon economic dispatch about the method of congestion management. Its divided four problems to explain. In the first problem, we defines the expression with the relation between electric power generating and current flow value with the method of linearity regression;Problem two, based the principle of market business with the principle of safety,conciseness,reason and fair ,we bring forward two rules to counting congestion charge; To problem three, followed the electric power market bargain principle,we draw up contribute beforehand case for ordered burthen ;Problem four, according to beforehand case examination appears to jam or not, we press step to put forward the programming model that solve the congestion management.The model is introduced the single target programming function “l(fā)inprog” and many targets function “fgoalattain” in MATLAB to solve.
The second part is based upon Optimal Power Flow (OPF) about the method of congestion management.The model on congestion management is build up under the condition of the bilateral bargain contract market, recur to the tool of OPF, lift a hand to according to the power station of the equilibrium market for the market offer to adjust solid, can cut down the some and bilateral amount of contract through the competing price means as occasion requires, the target function for adjust the expenses minimum, and adopted the 5 nodes simulation electric power system to carried on the examination to that model.
Keywords: transmission congestion management; linprog; fgoalattain;economic dispatch; Optimal Power Flow(OPF).
