摘　　要：提出了一种基于功率交换和截断总体最小二乘法的线损预测方法,对多区域间的输电网电力配置具有重要指导意义。构建了结合功率交换的线损预测模型,根据各投标区域的位置、区域间联络线的传输容量及具体电价求解功率交换预测值。考虑了各区域的电力需求、供应和风电的总水平以及与相邻区域的功率交换等多种因素的共同作用,提出了基于截断总体最小二乘法的线损预测算法。利用公开数据集和采集的实测数据集验证了文中方法的有效性。A line loss prediction method based on power exchange and truncated total least square method is proposed,which is of great significance for guiding the power allocation of transmission network among multiple regions.Firstly,a line loss prediction model combined with power exchange is constructed,and the power exchange prediction value is calculated according to the location of each bidding area,transmission capacity of interconnection lines between regions and the specific electricity price.Secondly,considering the power demand,supply and the total level of wind power in each region,as well as the power exchange with adjacent regions,a line loss prediction algorithm based on the truncated total least square(TTLS) method is presented.Finally,the effectiveness of the proposed method is verified by the open data set and the collected measured data set.
