Heuristic Approach for Distribution Systems Feeder Reconfiguration to Line Maximum Loadability

International Journal on Electrical Engineering and Informatics, 2012
This paper presents a heuristic approach for optimal feeder reconfiguration of radial distribution systems (RDS). Optimal feeder reconfiguration involves the selection of the best set of branches to be opened by considering the all tie switches, such that the resulting RDS has the desired performance. Amongst the several performance criteria considered
