Centralized expansion planning of the transmission network in competitive markets. A solution based on a hybrid approach

In the framework of the electric industry where the generation is competitive, the regulation visualizes different schemes of transmission network expansion planning, among them the Centralized Transmission Expansion Planning CTEP is recognized, which is important in the Latin American environment. Very little effort has been assigned to solve the dynamic model of the CTEP, because of the complexity of the optimization problem, which has been simplified in static and multi-stage models to reduce the calculation time, but from this viewpoint the commissioning year in service has been ignored. In this research, a methodology for the decision-making in the CTEP solution process, under a deterministic framework is proposed. A hybrid approach in order to solve the dynamic model of the CTEP is developed, based on: a meta-heuristic evolutionary algorithm, a heuristic procedure and the classic dynamic programming method.
