This paper presents a mathematical model of the problem of the planning of systems of electrical distribution which considers the location and sizing of new feeders and substations, and the reconductorazing of existing feeders. The mathematical model used is of the type Lineal Mixed Integer Programming (LMIP) and to solve it, an algorithm of Branch and Bound is used. In order to test the proposed algorithm, the electrical system of the city of Pereira is used. [ABSTRACT FROM AUTHOR]

Abstract
This paper presents the long term planning analysis of a power transmission system as a nonlinear integer mixed optimization problem that includes in the objective function the expected power not served as index that explicitly measures the reliability. This problem is solved combining the techniques of genetic algorithms for the optimization part and the state space enumeration for the reliability. As a real example, an expansion study of the power transmission system that serves the city of Pereira in Colombia is presented. [ABSTRACT FROM AUTHOR]
