【摘要】：面對大規(guī)模風(fēng)電并網(wǎng)運行時接入容量受限、棄風(fēng)量大的情況,通常的做法是考慮利用儲能系統(tǒng)來提高電網(wǎng)接納風(fēng)電能力,但如何評價其整體效益是必須解決好的問題。為此分析了抽水蓄能系統(tǒng)的投資成本、經(jīng)濟效益及其運行約束,揭示了風(fēng)電-抽水蓄能聯(lián)合系統(tǒng)綜合效益和儲能容量之間在地區(qū)電力系統(tǒng)最優(yōu)化運行條件下的隨動機理,建立了求取綜合效益的數(shù)學(xué)模型,提出了綜合效益的評價方法。該方法基于相互匹配的火電機組出力曲線、風(fēng)功率曲線和電網(wǎng)負(fù)荷特性,結(jié)合火電機組裝機情況,并利用系統(tǒng)頻率與負(fù)荷或發(fā)電變化之間的關(guān)聯(lián)關(guān)系,量化分析了抽水蓄能系統(tǒng)的容量、運行年限、成本、收益等因素的變化對綜合效益和風(fēng)電接納容量的影響。實例分析表明文中所提評價方法是有效的。
[Abstract]:When large-scale wind power is connected to the grid, the access capacity is limited and the wind capacity is high. The usual method is to consider using energy storage system to improve the capacity of the grid to accept wind power. However, it is necessary to solve the problem of how to evaluate its overall benefit. Therefore, the investment cost, economic benefit and operation constraints of pumped storage system are analyzed. This paper reveals the following mechanism between the comprehensive benefit and the energy storage capacity of the combined wind-pumped storage system under the optimal operation conditions of the regional power system, and establishes a mathematical model to obtain the comprehensive benefit. A comprehensive benefit evaluation method is put forward, which is based on the matching power curve, wind power curve and load characteristics of power grid, combined with the installation of thermal power units. Based on the correlation between system frequency and load or generation change, the capacity, operation life and cost of pumped storage system are analyzed quantitatively. The influence of the change of income and other factors on the comprehensive benefit and the capacity of wind power acceptance is discussed. The analysis of examples shows that the evaluation method proposed in this paper is effective.
