摘要:
In the normal operation of a distribution system, substation main transformer and feeder load balancing is important since it can reduce the risk of overloads due to load changes. Load balancing is usually achieved by reconfiguring the distribution feeders and redistributing the load currents among feeders and transformers. In the early studies on feeder reconfiguration, transformer load balancing and feeder load balancing were usually performed individually. A heuristic search approach in which transformer load balancing and feeder load balancing are performed simultaneously has been recently proposed by the authors in order to improve efficiency. However, the solution obtained by using the aforementioned algorithm may be a local minimum. In this paper, a refined heuristic search approach for substation main transformer and feeder load balancing is proposed, in order to reach a better solution.
