GALLEGO PAREJA, Luis Alfonso; ROMERO, Rubén Augusto  and  LOPEZ LEZAMA, Jesús María. Transmission network expansion planning considering contingencies and uncertain demand. Rev.fac.ing.univ. Antioquia [online]. 2009, n.48, pp.188-200. ISSN 0120-6230.

This paper presents a methodology and a mathematical model to solve the expansion planning problem that takes into account the effect of contingencies in the planning stage, and considers the demand as a stochastic variable within a specified range. In this way, it is possible to find a solution that minimizes the investment costs guarantying reliability and minimizing future load shedding. The mathematical model of the expansion planning can be represented by a mixed integer nonlinear programming problem. To solve this problem a specialized Genetic Algorithm combined with Linear Programming was implemented.

Keywords : Transmission planning; genetic algorithms; power system reliability; uncertain demand.
