Compensación VOLT-VAR mediante despacho óptimo de generación en microrredes eléctricas con alta penetración de generación distribuida

Abstract

In the present work, an active and reactive power compensation model was developed, in an electric microgrid to which an optimal power flow was implemented, for a precise analysis of the flow circulating through the microgrid, favoring the integration of generation sources of renewable origin. The proposed method is by mixed integer linear programming (MILP), to which distributed generation (GD) was incorporated in one or more established bars. The algorithm calculates an optimal solution, which satisfies the necessary requirements to guarantee reliability and quality in the microgrid; developed in the GAMS tool minimizing operating costs in the system as an objective function. As a final analysis, a comparison of data from the system without GD and with GD was carried out, highlighting an improvement in the voltage profiles, reduction of the losses of active power in the lines, an improvement in the power factor and angular behavior; that complies with the restrictions set forth at a minimum operating cost. To model the problem, the IEEE 9-bar system was used.
