Substation Locating and Sizing in Rural Power System Based on GIS and Modified Differential Evolution Algorithm

A modified differential evolution (MDE) algorithm is introduced to solve the problems of substation location optimization based on GIS. Numerical study is carried out by using three test-functions to the MDE algorithm which introduces inertia scaling factor, and the result is compared with that of dynamic differential evolution .Analysis results show that the efficiency of modified differential evolution is significantly improved for adjusting the inertia scaling factor F scope purposefully to different function. The model of the problem involving the geographic information, the rural power network characteristic and its located complex geographical environment make the given solution more effective and feasible.
