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
风力发电是风能利用的主要形式。风电作为不同与火电、水电等常规的电源,其输出功率与该时刻的风速密切相关,具有间歇性和波动性。风电的大规模并网会对原电网的稳定性和电能质量[1-2]造成巨大影响,甚至会导致电网崩溃,风电输出不稳定成为了限制风电并网的重要原因。增加储能设备可以为风电并网提供有效的支撑,增强电网的调频、调峰能力,有效解决风能的随机性和波动性的问题[3-4]。……
