An Approach of Substation Location and Capacity Planning Considering Geographical Constraints

In order to address the issue of substation location and capacity planning under geographical constraints, an approach to substation location and capacity planning considering geographical constraints is suggested. Firstly, the process for substation location and capacity planning considering geographical constraints is given, and a substation site and capacity planning model including geographical penalty coefficient and minimum target annual cost is established. Then, a hybrid algorithm combining particle swarm optimization and differential evolution is proposed for solving the model, and its optimization performance is improved by improving the inertia weight coefficient. The validity of the suggested algorithm can be confirmed by contrasting the standard test function with other algorithms. Finally, an example is provided to illustrate the feasibility of the proposed model and solution method.
