Characteristic analysis of weather loads for East China Power Grid

Based on the analysis of weather document and historical loads of provinces covered by East China Power Grid,the key weather factors influencing the weather load of the Grid were found out,and the relation model was established.The load fitted by the model is compared with the weather load obtained by the "typical day" method,and based on that the fitting relation between the weather load of East China Power Grid and the key weather factors are deduced.
