【摘要】：隨著全球工業(yè)化的不斷深入，對化石能源的需求也不斷上升。但是，因為化石能源是不可再生能源，同時會對環(huán)境造成非常大的污染。所以，大力發(fā)展新能源來替代傳統(tǒng)能源是大勢所趨。風(fēng)能作為一種綠色清潔且可再生的能源受到了各個國家的青睞。近年來，隨著一些大型風(fēng)力發(fā)電場的并網(wǎng)運行，風(fēng)電對整個電力系統(tǒng)的影響也會越大。通常認為風(fēng)電的輸出功率會對電價產(chǎn)生一定程度的影響，因此，在大型風(fēng)電場并網(wǎng)后，需要分析風(fēng)電輸出功率的變化將對電力市場中用戶的價格響應(yīng)以及清算價格產(chǎn)生怎樣的影響。 本文介紹了需求側(cè)響應(yīng)的基本理論以及電價的基本概念和定價方法，研究的主要內(nèi)容如下： 第一，通過構(gòu)造短期供給曲線確定現(xiàn)貨定價模型，同時從風(fēng)電供給曲線、常規(guī)發(fā)電供給曲線得到市場短期復(fù)合供給曲線。結(jié)合這兩個方面，研究風(fēng)電供應(yīng)與電力現(xiàn)貨價格的關(guān)系，，論證了風(fēng)力發(fā)電是如何影響電力市場短期供給曲線，從而進一步的影響到市場的每個小時的價格。 第二，建立一個電力需求價格響應(yīng)的模型，使用電力需求的交叉價格彈性系數(shù)和自身價格彈性系數(shù)來使模型參數(shù)化，同時對一系列的情況進行詳細的分析。重點是對價格的短期影響進行分析。 第三，模擬和分析了負荷時間序列和價格之間不斷地調(diào)整直到最后平衡的過程，研究了風(fēng)電上網(wǎng)對于負荷和市場清算價格的影響。 最后，以算例形式模擬分析了某電力系統(tǒng)一天內(nèi)負荷對價格的響應(yīng)行為。 綜上所述，本論文研究解決的問題對于增強社會對風(fēng)力發(fā)電的認識，完善風(fēng)電等新能源發(fā)電項目的技術(shù)經(jīng)濟評價理論，促進我國新能源發(fā)電事業(yè)健康持續(xù)發(fā)展具有重要的理論與實踐作用。
[Abstract]:With the deepening of global industrialization, the demand for fossil energy is also rising. However, because fossil energy is non-renewable energy, at the same time will cause great pollution to the environment. Therefore, the development of new energy to replace traditional energy is the general trend. Wind energy as a kind of green clean and renewable energy has been favored by all countries. In recent years, with the grid-connected operation of some large-scale wind farms, the impact of wind power on the whole power system will become greater. It is generally believed that the output power of wind power will have a certain effect on the electricity price. Therefore, after the large-scale wind farm is connected to the grid, It is necessary to analyze how the change of wind power output will affect the price response and liquidation price of consumers in the electricity market. This paper introduces the basic theory of demand-side response and the basic concept and pricing method of electricity price. The main contents of the study are as follows: first, the spot pricing model is determined by constructing short-term supply curve, and the spot pricing model is determined by wind power supply curve. Conventional power supply curve to obtain the market short-term composite supply curve. Combined with these two aspects, this paper studies the relationship between wind power supply and spot price of electricity, and demonstrates how wind power generation affects the short-term supply curve of electricity market, thus further affecting the price of every hour of the market. Secondly, a model of electricity demand price response is established. The cross-price elasticity coefficient of electricity demand and its own price elasticity coefficient are used to parameterize the model. At the same time, a series of situations are analyzed in detail. The emphasis is on the analysis of the short-term impact of prices. Thirdly, the process of adjusting load time series and price to the final equilibrium is simulated and analyzed, and the influence of wind power access on load and market clearing price is studied. Finally, the response behavior of a power system load to price in one day is simulated and analyzed by a numerical example. To sum up, the problems studied and solved in this paper can enhance the society's understanding of wind power generation and improve the theory of technical and economic evaluation of new energy generation projects, such as wind power. It is important to promote the healthy and sustainable development of new energy power generation in China.
