A multiobjective Var/Volt Management System in Smartgrids

Abstract This paper presents a methodology for optimal Var/Volt management of Distributed Generation (DG) and FACTS units in power networks. The methodology is based on Genetic Algorithm in order to achieve the desired system reliability requirements taking into account voltage stability limits. Results indicate that the proposed formulation could be used to determine the optimal points in which the incorporation of DG units and connection of FACTS devices would allow a voltage stability enhancement, minimizing, at the same time, real power losses and minimizing the investment cost of the FACTS devices.
