摘要
中国经济发展和风电资源的分布不均衡特点决定了大规模风电需要通过特高压专用通道远距离输送至东、中部负荷中心,选择合理的落点是一个复杂的多目标决策问题。提出了大规模风电特高压专用通道落点优选方法,分析了基于熵权决策理论的决策过程,建立了可以全面评估大规模风电接入受端电网的安全稳定水平、电力电量需求、网架结构和经济性等重要因素的评价指标体系。将该方法应用于中国某省接纳北方大规模风电特高压专用通道的落点优选实际案例,结果表明该方法可以有效评估大规模风电接入受端电网的影响,可为风电落点优选决策提供参考。
Uneven distribution characteristics of economic and wind energy decide that large scale wind power should be delivered to northern or eastem load centers in China. It＇s a complicated multiple objective decision making problem to select an appropriate wind access point. This paper introduced a selection method of optimal access point for large scale wind power through the ultra-high voltage （UHV） lines and analyzed its decision process based on decision theory of entropy weight. A comprehensive index system to evaluate the access point of large scale wind power was established which took into account the power demand, network frame structure, level of safety and stability, economy of the receiving end and etc. This method was used to select an access point for one province receiving large scale wind power from northem part in China through UHV channel. The result indicates that this method can evaluate the influences of large scale wind power on the receiving system and provide reference to the selection of optimal access point for wind power UHV channel
