Research of loss reduction scheme for regional distribution grids based on G1-GRA

Abstract

Abstract-this paper proposed a comprehensive loss reduction evaluation method for regional distribution grids based on G 1 method and grey relational analysis (GRA). The method is good at avoiding the prominent disadvantages of analytic hierarchy process (AHP) by determining the weights of evaluation indices. Otherwise, the method of grey relational analysis was used for dimensionless processing. Therefore, the authors put forward an implementation scheme about the preferred area for loss reducing and the optimal index, which is proved to be practical, significant, and applicable.
