Optimized switching using heuristic algorithm to support the restoration of distribution systems

This paper presents a methodology for switching optimization in the distribution network on the occasion of a fault, or to proceed a scheduled outage to make a preventive maintenance service. Additionally, a correspondent software (called CEMOP) has been developed for reconfiguration purposes due to forced or scheduled outages on distribution networks, considering parallel interconnection with other feeders. This project has been developed in partnership with CEMAR, an electric utility located at the northeast of Brazil which supplies approximately 1.8 million customers (approximately 6.6 million inhabitants), in the state of Maranhão, in Brazil.
