不确定环境下江苏500kV立体电网新能源互联层研究

Study on Interconnect Layer of New Energy in Jiangsu 500 kV Stereoscopic Power Grid with Uncertainty

为了充分利用新能源出力间的互补特性,减小不确定性因素对电网带来的影响,结合江苏地区新能源出力特性,分析了江苏各新能源基地出力间的Spearman相关性,并根据新能源基地间的互补特性,提出了500kV立体电网新能源互联层的构建方法。对含新能源互联层的立体电网的分析结果表明,构建新能源互联层的江苏500kV立体电网中过江通道潮流分布更为合理,新能源接纳能力得到一定的提升。

In order to take full advantage of the new energy complementary characteristic between outputs and to reduce the effect of the uncertain factors on the power grid,combining with the new energy outputs characteristic in Jiangsu area,this paper analyzed Spearman correlation between outputs in each new energy base of Jiangsu and proposed the construction method of 500 kV stereoscopic power grid new energy interconnect layer.The results of this study show that with the new energy interconnect layer,the power flow distribution in pathway crossing rivers is more reasonable and the consumptive abilities of new energy are improved.
