摘要
围绕叶尔羌河流域喀什地区水光可再生能源发电互补特性分析与量化问题,基于Pearson、Spearman秩、Tau-b相关系数,提出一种互补系数计算方法,研究该地区莎车、英吉沙、叶城网架节点的水光出力互补规律.以优先消纳光伏出力前提下的源-荷匹配系数最小为目标,建立水光互补联合调度模型,对水电出力过程进行优化调整.结果表明:在小时尺度上,3 个相关系数值范围为-0.849～-0.407,英吉沙、莎车节点的水光互补系数分别为 0.715、0.501,表明水光出力具有一定的互补性;在日尺度和月尺度上,各节点的水光互补性相对较弱.通过水光互补模型优化后,水光出力的互补性提高,在小时尺度、日尺度、月尺度上,水光互补系数分别提高至0.750、0.755、0.621,相对于原互补系数分别提高了 37.6%、221.3%、37.4%.
Abstract
Focusing on the analysis and quantification of the complementary characteristics of hydro-solar renewable energy power generation in Kashgar Prefecture of the Yarkand River Basin,based on the correlation coefficients of Pearson,Spearman rank and Tau-b,a method for calculating the complementarity coefficient of hydropower and optoelectronic was proposed to study the complementary law of hydro-solar out-put at the grid nodes of Shache,Yingjisha and Yecheng in the area.With the goal of minimizing the source-load matching coefficient under the premise of giving priority to the consumption of photovoltaic output,a joint scheduling model of hydro-solar complementation was estab-lished to optimize and adjust the hydropower output process.The results show that on the hourly scale,the values of the three correlation coef-ficients range from-0.849 to-0.407,and the hydro-solar complementarity coefficients of the Yingisha and Shache nodes are 0.715 and 0.501,respectively,indicating that the hydropower and optoelectronic have a certain complementarity.On the daily and monthly scales,the complementarity of hydropower and optoelectronic at each node is relatively weak.After the optimization of the hydro-solar complementation model,the complementarity of hydro-solar output is improved,and the hydro-solar complementation coefficients increase to 0.75,0.755 and 0.621 on the hourly,daily,monthly scales,respectively,which are 37.6%,221.3%and 37.4%higher than the original complementation coefficients.
