Spatial electric load forecasting based on AHP and TOPSIS method

The key problem of the spatial load forecasting is how to select the load density. As the existing methods to obtain load density hardly meeting the accuracy requirements in actual project, the theory of AHP and TOPSIS is introduced to calculate the load density. The presented method not only adopts the theory of AHP to determine the weight of evaluation indicators, but also makes use of the TOPSIS to standardize and calculate the sorting for evaluation indicators. The influence factors of load density are quantitied to choose the appropriate load density by the theory of AHP and TOPSIS. Moreover, the method of similar degree was used to modify the load density. The model and the method in this paper were used in a large number of actual projects. The results showed that proposed method can calculate the load density quickly and maintain requirement precision
