Loading balance of main transformers and distribution feeders using the immune algorithm

This paper examines the application of the immune algorithm for the problem of transformer and feeder loading balance. This algorithm prevents the possibility of stagnation in the iteration process and achieves the fast convergence for the global optimization. A Taipower distribution system with 12 main transformers and 68 feeders is selected for computer simulation to demonstrate the effectiveness of the proposed methodology for solving the optimal switching operation of distribution systems to enhance the loading balance of distribution feeders and transformers.
