Generic Switching Actions of Distribution System Operation Using Dynamic Programming Method

The distribution system configuration can be modified using line switches. This approach enables the loading of line segments and distribution feeders to be adjusted to obtain the load balance and enhance the system performance due to loss minimization resulting from the presented generic switching actions. This paper develops the optimal switching actions for the 22.8KV underground distribution system within the Taichung distribution automation system (DAS) in the Taiwan Power Company (Taipower) system. The dynamic programming method (DP) is designed to determine the optimal switching actions for a single day via feeder reconfiguration.
