【摘要】：現(xiàn)今，隨著經(jīng)濟(jì)的發(fā)展，電力系統(tǒng)的發(fā)展越來越快，，而目前來說我國電力系統(tǒng)的建設(shè)仍然相對(duì)滯后，存在很多問題，其中電力系統(tǒng)無功優(yōu)化是一個(gè)引人關(guān)注的問題，其對(duì)保證系統(tǒng)安全性和經(jīng)濟(jì)性有著十分重要的意義，因此越來越多的電力工作者開始研究如何在滿足電力需求以及保證供電可靠性的前提下，充分依靠無功功率來降低網(wǎng)絡(luò)損耗，提高系統(tǒng)運(yùn)行經(jīng)濟(jì)性，最終達(dá)到提高供電電能質(zhì)量的目的。 本文首先深入研究了電力系統(tǒng)無功優(yōu)化計(jì)算的背景知識(shí)和GAMS（GeneralAlgebraic Modeling System），即通用數(shù)學(xué)模型系統(tǒng)軟件。在無功優(yōu)化計(jì)算的背景知識(shí)這部分中，不僅研究了電力系統(tǒng)消耗無功功率的設(shè)備與補(bǔ)償裝置，而且還簡單的介紹了電力系統(tǒng)的兩種無功控制方式；介紹常用的無功優(yōu)化控制模型。在GAMS軟件這部分中，分別介紹了GAMS的開發(fā)背景、基本特征、模型與結(jié)構(gòu)以及模型的分類、GAMS常用的求解器，并且研究了基于GAMS的電力系統(tǒng)無功優(yōu)化的基礎(chǔ)。最后以一個(gè)8節(jié)點(diǎn)的系統(tǒng)為例進(jìn)行了GAMS建模的示例，十分直觀的展示了GAMS程序編寫的方法和流程。 其次，建立了連續(xù)無功優(yōu)化的數(shù)學(xué)模型，包括目標(biāo)函數(shù)、等式約束和不等式約束。對(duì)WardHale6和IEEE14系統(tǒng)兩個(gè)算例按照GAMS的建模的方法研究分析，確定了狀態(tài)變量和控制變量，建立了一個(gè)可以描述為非線性規(guī)劃問題的數(shù)學(xué)模型。以系統(tǒng)有功損耗最小為目標(biāo)函數(shù)，以電力系統(tǒng)功率平衡為等式約束，以電容器補(bǔ)償容量和節(jié)點(diǎn)電壓為不等式約束，通過研究看出通過無功優(yōu)化，有功功率損耗明顯減少，達(dá)到了優(yōu)化效果，證明了方法的實(shí)用性。然后，研究了地區(qū)電壓無功控制的三種基本方式，并在連續(xù)無功優(yōu)化的基礎(chǔ)上建立了基于GAMS的地區(qū)電壓無功控制的數(shù)學(xué)模型，并利用GAMS對(duì)IEEE14系統(tǒng)進(jìn)行研究，表明用GAMS進(jìn)行計(jì)算能使綜合經(jīng)濟(jì)效益有所提高。 最后，介紹了用JAVA進(jìn)行GAMS二次開發(fā)的基本方法，介紹了代碼編寫的流程和用法。最后通過實(shí)際算例驗(yàn)證了將GAMSAPI引入Eclipse中，使用GAMS的底層算法，對(duì)GAMS進(jìn)行二次開發(fā)是成功的。通過將GAMS二次開發(fā)與InterPSS相對(duì)接，可以充分展示基于GAMS開發(fā)電力系統(tǒng)實(shí)用優(yōu)化程序的巨大潛力。
[Abstract]:Nowadays, with the development of economy, the power system is developing more and more rapidly, but the construction of power system in our country is still lagging behind, there are many problems, among which reactive power optimization of power system is a problem that attracts much attention. It is of great significance to ensure the safety and economy of the system. Therefore, more and more electric power workers begin to study how to meet the power demand and ensure the reliability of power supply. Reactive power can be used to reduce the network loss and improve the operation economy of the system. Finally, the power quality of power supply can be improved. In this paper, the background knowledge of reactive power optimization calculation and GAMS (GeneralAlgebraic Modeling System), (General Mathematical Model system) software are studied. In the part of background knowledge of reactive power optimization calculation, not only the equipment and compensation device of reactive power consumption in power system are studied, but also two reactive power control modes of power system are introduced simply. The common reactive power optimal control model is introduced. In the part of GAMS software, the development background, basic characteristics, model and structure of GAMS, classification of model, common solver of GAMS are introduced, and the foundation of reactive power optimization based on GAMS is studied. Finally, taking an 8-bus system as an example, an example of GAMS modeling is given, and the method and flow of GAMS programming are shown intuitively. Secondly, the mathematical model of continuous reactive power optimization is established, including objective function, equality constraint and inequality constraint. According to the modeling method of GAMS, two examples of WardHale6 and IEEE14 systems are studied and analyzed. The state variables and control variables are determined, and a mathematical model which can be described as a nonlinear programming problem is established. Taking the minimum active power loss as the objective function, the power balance of the power system as the equality constraint, and the capacitor compensation capacity and the node voltage as the inequality constraints, the study shows that the reactive power loss is significantly reduced by reactive power optimization. The optimization effect is achieved and the practicability of the method is proved. Then, three basic methods of regional voltage and reactive power control are studied, and the mathematical model of regional voltage and reactive power control based on GAMS is established on the basis of continuous reactive power optimization, and the IEEE14 system is studied by GAMS. It is shown that the comprehensive economic benefit can be improved by GAMS calculation. Finally, the basic method of GAMS secondary development with JAVA is introduced, and the flow and usage of code writing are introduced. Finally, a practical example is given to verify the success of the secondary development of GAMS by introducing GAMSAPI into Eclipse and using the underlying algorithm of GAMS. By docking GAMS secondary development with InterPSS, the great potential of developing practical optimization program for power system based on GAMS can be fully demonstrated.
