摘要：儲能技術的發(fā)展為風電的大規(guī)模并網(wǎng)后造成的電能質量問題提供了有效解決方法。合理的儲能設備容量不僅能夠提高儲能設備的利用效率，也能平滑風電輸出，改善電能質量。本文考慮計及儲能設備減少旋轉備用容量的風電場經(jīng)濟效益及功率波動的平衡性，采用多目標粒子群算法進行風電場儲能裝置的容量優(yōu)化，以Pareto最優(yōu)解集的形式表示儲能設備帶來的風電場經(jīng)濟性與穩(wěn)定性多目標的兼顧。并通過某地的風電場典型日出力情況作為仿真實例，驗證優(yōu)化所得結果的有效性，可為風電場的儲能裝置容量選擇提供實用的參考方案。

Abstract：The development of energy storage technology provides an effective method for solving power quality issue caused by large scale grid-connected wind farm. Rational capacity of energy storage device can not only enhance utilization efficiency of energy storage device, but also smooth wind power output, and improve power quality. In this paper, by considering that the economical profit of wind farm for rotating backup capacity can be reduced by energy storage device and the balance of power fluctuation, multi-objective particle swarm optimization algorithm is used to optimize capacity of storage equipment for wind farm, and both the economic and stability of wind farm brought by energy storage device can be reflected by using Pareto optimal solution set. By taking classical day power output for one wind farm as simulation case, the effectiveness of proposed method is verified, and the works in this paper can provide reference applicable scheme for selecting capacity of energy storage device for wind farm.

Keywords：wind power farm;energy storage device;capacity optimization; particle swarm optimization;the multi-objective optimization

0引言

風力發(fā)電是風能利用的主要形式。風電作為不同與火電、水電等常規(guī)的電源，其輸出功率與該時刻的風速密切相關，具有間歇性和波動性。風電的大規(guī)模并網(wǎng)會對原電網(wǎng)的穩(wěn)定性和電能質量[1-2]造成巨大影響，甚至會導致電網(wǎng)崩潰，風電輸出不穩(wěn)定成為了限制風電并網(wǎng)的重要原因。增加儲能設備可以為風電并網(wǎng)提供有效的支撐，增強電網(wǎng)的調頻、調峰能力，有效解決風能的隨機性和波動性的問題[3-4]。……
