【摘要】：大系統(tǒng)理論是專門研究為了求解大規(guī)模系統(tǒng)的理論,其核心思想是通過模型簡(jiǎn)化、降階、分解協(xié)調(diào)或者分散控制等手段,把一個(gè)大規(guī)模系統(tǒng)拆分為小系統(tǒng)后再去求解,避免直接求解大系統(tǒng),進(jìn)而避免了“維數(shù)災(zāi)”的發(fā)生。風(fēng)水火電站聯(lián)合調(diào)度系統(tǒng)是一個(gè)典型的大系統(tǒng),它由三類電站組成,電站之間相互關(guān)聯(lián)。通常以火電機(jī)組煤耗量最小為目標(biāo)函數(shù),并且需要同時(shí)考慮火電機(jī)組、水電站和風(fēng)電場(chǎng)的約束條件。因此是一個(gè)典型的高維、非凸、多約束的復(fù)雜規(guī)劃問題。本文從大系統(tǒng)理論出發(fā),針對(duì)風(fēng)水火電站聯(lián)合調(diào)度大問題,提出了一種通用的大系統(tǒng)分解協(xié)調(diào)兩層求解模型：上層是協(xié)調(diào)層,負(fù)責(zé)更新和發(fā)送協(xié)調(diào)變量；下層是風(fēng)、水、火電站子問題。從而把風(fēng)水火電站聯(lián)合調(diào)度“大”問題分解成了單獨(dú)的風(fēng)、水、火電站“小”問題。下層子問題中,火電機(jī)組子問題通過動(dòng)態(tài)規(guī)劃法求解。針對(duì)不同的水電站模型,梯級(jí)水電站子問題通過大系統(tǒng)分解協(xié)調(diào)算法求解；單獨(dú)水電站子問題通過啟發(fā)式算法求解。風(fēng)電場(chǎng)子問題通過建立風(fēng)電功率預(yù)測(cè)輸出模型求解。上層協(xié)調(diào)層中,使用擬牛頓法(BFGS)更新協(xié)調(diào)變量,既保證了算法的收斂精度,又保證了算法的收斂速度。通過兩類風(fēng)水火電站聯(lián)合調(diào)度問題模型的實(shí)例仿真,驗(yàn)證了通用大系統(tǒng)分解協(xié)調(diào)模型求解風(fēng)水火電站聯(lián)合調(diào)度問題的可行性和通用性。
[Abstract]:The theory of large scale system is specially studied in order to solve the theory of large scale system. Its core idea is to divide a large scale system into a small system and then solve it by means of model simplification, order reduction, decomposition coordination or decentralized control. Avoid solving large system directly, and then avoid the occurrence of "dimension disaster". The wind-water power station joint dispatching system is a typical large-scale system, which is composed of three kinds of power stations, and the power stations are related to each other. Usually, the minimum coal consumption of thermal power units is taken as the objective function, and the constraints of thermal power units, hydropower stations and wind farms need to be considered at the same time. Therefore, it is a typical high-dimensional, non-convex, multi-constraint complex programming problem. Based on the large-scale system theory, this paper presents a general two-layer solution model of large scale system decomposition and coordination, which is responsible for updating and transmitting coordination variables. There are wind, water and thermal power station problems at the bottom. Thus, the "big" problem of the combined operation of the feng shui thermal power station is decomposed into a separate "small" problem of the wind, water and thermal power stations. In the lower subproblem, the subproblem of thermal power generating unit is solved by dynamic programming method. For different hydropower station models, the sub-problem of cascade hydropower station is solved by large-scale system decomposition and coordination algorithm, and the sub-problem of single hydropower station is solved by heuristic algorithm. The wind farm sub-problem is solved by establishing the wind power predictive output model. In the upper layer of coordination, the quasi-Newton method (BFGS) is used to update the coordination variables, which not only guarantees the convergence accuracy of the algorithm, but also ensures the convergence speed of the algorithm. The feasibility and generality of the general large-scale system decomposition and coordination model for solving the joint dispatch problem of the power plant are verified by the simulation of two kinds of wind power plant joint dispatch problem models.
