Mixed Integer Linear Programming Model for Optimal Allocation and Sizing of Substations Considering the Impact of Distributed Generation

Abstract

This study addresses the challenge of optimal planning of electrical energy distribution systems in the face of population and industrial growth and the disorderly installation of distributed generators. Aiming to improve the stability and quality of energy supply, a mathematical mixed integer linear optimization model is proposed for the optimal allocation of substations considering the insertion of renewable energy sources (distributed generators). One of the purposes is to identify the effects of including distributed generation in substation planning. The inclusion of renewable energy sources, such as distributed generators, is an aspect of great importance for improving electrical systems. The study also addresses the insertion of distributed generators in different proportions in order to enable not only comparison with the base case, but also with other cases and evaluate the best result in matters of improvement in system parameters and economic benefit.
