Planeamiento multiobjetivo de la expansión de la transmisión considerando seguridad e incertidumbre en la demanda

This paper presents a methodology for resolving the transmission expansion planning problem by considering single contingency criteria (N-1). Each bus bar in the power system considered future demand uncertainty. The planning problem was divided into an investment problem (calculating investment costs) and an operative problem (resolving power flows). A modified evolutionary elitist non-dominated sorted genetic algorithm (NSGA-II) was used for resolving the investment problem, determining several investment proposals where feasibility was evaluated by solving the operative problem. On the other hand, a high order interior point (HOIP) method was proposed for solving load flow problems. The methodology was tested by using two systems found in the specialised literature: IEEE-24 bus and Garver or IEEE-6 bus systems. The results, when compared with traditional ones, showed the proposed method's power and the multi-objective technique's convenience.
