Presented at B4 Poster Session, 2:30 PM Tuesday Giovanni Marin, Diego Tauta, Diego Henao, Andres Londoño, Andres Toro, Edgar Uribe, Alejandro Duque, and Mario Patino The growth in demand, the high penetration of small, distributed generation plants, and the increasing changes in power flow patterns typical of deregulated schemes are commonly the drivers for overloads in transmission system assets. This paper shows the planning process to eliminate the overloads found in the Valle de Aburrá region expansion plan in Medellín, Colombia, the planning process, and the successful results of the pilot project of the first D-FACTS installation in Latin America. In this project, it was possible to verify the operational reliability, performance, flexibility, and potential of D-FACTS on existing infrastructure. The study also emphasizes the social, environmental, and technical benefits the technology provides, including better rates for end-use customers. The authors compile lessons learned to encourage the incorporation of D-FACTS technology into the Colombian National Interconnected System (SIN).
