【摘要】：由于風的間歇性和隨機性,大規(guī)模風電廠內(nèi)部的調(diào)度規(guī)劃面臨著一些困境。風電廠的調(diào)度規(guī)劃的根本目的是在滿足電網(wǎng)需求的同時,盡可能地最小化風電廠運營的總成本,并且保證電網(wǎng)的運行安全。本研究針對這個問題提出了一個動態(tài)經(jīng)濟調(diào)度模型和相應的解決方法。此次研究的目標函數(shù)是風電廠的運營總成本,其中包括電力短缺成本、風機運維成本和風機啟動成本。為了求解文中提出的調(diào)度規(guī)劃模型,本文應用了PSSWO算法,這是一種將傳統(tǒng)的粒子群優(yōu)化(PSO)算法與小世界網(wǎng)絡結(jié)構(gòu)相結(jié)合的強化算法。此外,本文還引入了一種溝通機制來進行半封閉群落之間的信息交換,以達到探索和利用之間的平衡。 之后,本研究設(shè)計了兩個仿真實驗來驗證和分析由模型產(chǎn)生的優(yōu)化調(diào)度規(guī)劃方案。為了評估優(yōu)化方案的效果,設(shè)定了一個基準規(guī)劃方案,用總成本收益比來說明經(jīng)過優(yōu)化后的方案優(yōu)于基準規(guī)劃方案的程度。實驗結(jié)果表明,通過模型計算得到的優(yōu)化調(diào)度規(guī)劃方案的表現(xiàn)要優(yōu)于基準規(guī)劃方案。通過分析優(yōu)化后的規(guī)劃方案,可以看出,并不是所有高功率的風機都一直處于運行狀態(tài)就能滿足風電廠運營的要求,這是因為總成本的三個組成部分之間存在著一種微妙的平衡,必須對風機的啟停有所判斷,才能達到總成本最小化的目的。 最后,本文根據(jù)澳大利亞—新西蘭風險管理標準AS/NZS4360提出的標準過程,從風險的識別、分析、評估、控制、監(jiān)控和反饋等方面提出了一系列管理策略和措施,為未來的風電廠調(diào)度規(guī)劃和風險管理提供有益的啟示。
[Abstract]:Due to the intermittent and randomness of wind, the internal scheduling planning of large-scale wind power plants faces some difficulties. The fundamental purpose of the scheduling planning of wind power plants is to minimize the total operating cost of wind power plants while satisfying the demand of the power network. In order to solve this problem, a dynamic economic dispatching model and corresponding solutions are proposed. The objective function of this study is the total operating cost of wind power plant, including the cost of power shortage. In order to solve the scheduling planning model proposed in this paper, the PSSWO algorithm is applied, which combines the traditional particle swarm optimization (PSO) algorithm with the small-world network structure. This paper also introduces a communication mechanism to exchange information between semi-closed communities in order to achieve a balance between exploration and utilization. Then, two simulation experiments are designed to verify and analyze the optimal scheduling scheme generated by the model. In order to evaluate the effect of the optimization scheme, a benchmark planning scheme is set up. The degree to which the optimized scheme is superior to the baseline planning scheme is illustrated by the total cost-benefit ratio. The experimental results show that, The performance of the optimal scheduling plan obtained by the model calculation is better than that of the benchmark planning scheme. Through the analysis of the optimized planning scheme, it can be seen that, Not all high-power fans can meet the operational requirements of wind power plants if they are always in operation. This is because there is a delicate balance between the three components of the total cost, and it is necessary to judge the starting and stopping of the fans. In order to achieve the goal of minimizing the total cost. Finally, according to the standard process proposed by Australia New Zealand risk Management Standard (AS/NZS4360), this paper puts forward a series of management strategies and measures from the aspects of risk identification, analysis, evaluation, control, monitoring and feedback. For the future wind power plant scheduling planning and risk management to provide useful inspiration.
