【摘要】：隨著世界范圍內(nèi)常規(guī)化石能源的日趨枯竭以及環(huán)境問題的日益突出，清潔、綠色的可再生能源得到了廣泛的關(guān)注。由于風(fēng)力發(fā)電具有技術(shù)成熟、適宜規(guī)�；_發(fā)以及成本相對較低等特點(diǎn)，近年來發(fā)展十分迅速，具有良好的發(fā)展前景。但是風(fēng)力發(fā)電具有隨機(jī)性和波動性的特點(diǎn)，隨著風(fēng)電裝機(jī)容量的快速增加和風(fēng)電場規(guī)模的不斷擴(kuò)大，大規(guī)模風(fēng)電并網(wǎng)將對電網(wǎng)調(diào)峰帶來一定的影響。 本文從電網(wǎng)調(diào)峰能力的角度來研究風(fēng)電消納能力，針對風(fēng)電并網(wǎng)后電網(wǎng)調(diào)峰充裕性評估問題展開研究。首先介紹了國內(nèi)外風(fēng)電行業(yè)的發(fā)展?fàn)顩r，指出了研究風(fēng)電接入對電力系統(tǒng)調(diào)峰能力影響的重要性，簡述了風(fēng)力發(fā)電的特點(diǎn)，介紹了風(fēng)電并網(wǎng)方式，，分析了風(fēng)電接入對電網(wǎng)調(diào)峰的影響以及影響風(fēng)電并網(wǎng)系統(tǒng)調(diào)峰能力的因素。然后論述了蒙特卡洛模擬法的基本思想和理論基礎(chǔ)，對其特點(diǎn)和應(yīng)用范圍進(jìn)行了分析。最后，在分析風(fēng)電并網(wǎng)后系統(tǒng)調(diào)峰需求變化的基礎(chǔ)上，以計(jì)及風(fēng)電隨機(jī)波動和常規(guī)機(jī)組隨機(jī)停運(yùn)等不確定性因素為導(dǎo)向，基于序貫蒙特卡洛模擬法，提出了適用于大規(guī)模風(fēng)電并網(wǎng)的系統(tǒng)調(diào)峰充裕性評估方法，根據(jù)系統(tǒng)調(diào)峰不足概率評價(jià)調(diào)峰充裕性，以IEEE-RTS79系統(tǒng)作為算例進(jìn)行仿真分析，驗(yàn)證了所述方法的可行性和有效性。
[Abstract]:With the depletion of conventional fossil energy and the increasingly prominent environmental problems, clean and green renewable energy has received extensive attention. Because of the mature technology of wind power generation, Suitable for large-scale development and relatively low cost, it has developed very rapidly in recent years and has a good prospect. However, wind power generation has the characteristics of randomness and volatility. With the rapid increase of wind power installed capacity and the continuous expansion of wind farm scale, large-scale wind power grid will have a certain impact on peak-shaving. In this paper, the wind power absorption capacity is studied from the point of view of the peak-shaving ability of the power grid, and the evaluation of the power grid peak shaving adequacy after the wind power is connected to the grid is studied. Firstly, the development situation of the wind power industry at home and abroad is introduced. This paper points out the importance of studying the influence of wind power access on the peak-shaving ability of power system, briefly describes the characteristics of wind power generation, and introduces the mode of wind power grid connection. This paper analyzes the influence of wind power access on the peak shaving of power grid and the factors that affect the peak shaving ability of wind power grid connected system. Then the basic idea and theoretical basis of Monte Carlo simulation method are discussed, and its characteristics and application range are analyzed. On the basis of analyzing the change of peak shaving demand after wind power is connected to grid and taking into account the uncertain factors such as random fluctuation of wind power and random outage of conventional units, the sequential Monte Carlo simulation method is used. In this paper, a method for evaluating the peak-shaving adequacy of a system suitable for large-scale wind power grid connection is proposed. The feasibility and effectiveness of the proposed method are verified by using IEEE-RTS79 system as a numerical example to evaluate the peak-shaving adequacy according to the probability of system peak-shaving.
