Static expansion planning of electric power transmission systems using sensitivity indice

This paper presents a proposal aimed at the initialization of the multimodal optimization process to solve the problem of static expansion planning of electric power transmission systems. In order to, the proposed methodology uses a constructive heuristic algorithm based on an indice, in which the expansion decisions are relaxed and represented through the hyperbolic tangent function. The electric power transmission network is represented by a linearized load flow, direct current model (DC). The final expansion plans obtained by the proposed methodology were enough, showing that the use of the hyperbolic tangent function added to the adopted heuristic yielded an effective decision strategy. IEEE 24-bus system, real equivalent South Brazilian system and real Colombian System are tested by the methodology.
