Optimum location and sizing of capacitor banks using VOLT VAR compensation in micro-grids

Abstract

In this work, a mathematical model was implemented to solve optimally the location and sizing of capacitor banks in a micro-grid of electrical distribution. The proposed method is by particle swarm optimization (PSO), the solution will be obtained with dynamic programming, implementing an algorithm that will be developed entirely in MATLAB. The algorithm calculates the optimal solution satisfying the necessary requirements to guarantee the reliability of the system, as a case study will be used a model of a micro-grid typical of 5 bars, however, the algorithm was implemented General way and can respond correctly to multi-bar systems. As a final analysis we made a comparison of the system data without compensating and the system data compensated, highlighting an improvement in the voltage profiles, minimizing the losses in the lines, minimizing the total losses of the system, improving The power factor, decreasing the maximum voltage deviation and average voltage deviation, complying with a minimum possible cost restriction criterion.
