Técnicas de otimização aplicadas a sistemas elétricos de distribuição

Abstract

This work presents three techniques for optimization of systems of distribution of electric energy using optimal power flow based in the primal-dual methodology of interior points. The objective consists of getting the minimum of losses of active power in the feeders. The techniques are based on an algorithm for reconfiguration of the radial distribution feeders, a model for optimal localization of capacitors and taps adjustment of the voltage regulators. The gotten problems of optimization are of nature not linear mixing entire, the discrete variable are represented by functions continue and the physical and operative limits of the system are considered. The treatment of the discrete variable is formulated through a heuristic model step by step based in the coefficients of Lagrange. The techniques proposals are applied the diverse systems of the technical literature and also to a real large scale distribution system.
