MODEL FOR OPTIMAL SWITCHING DEVICES BASED ON IMMUNE ALGORITHM IN ELECTRIC DISTRIBUTION NETWORKS

This paper presents a model based on immune algorithm(IA) for optimal switching devices(OSDs) in electric distribution networks(EDNs). The model considers the investment, maintenance and outage costs. It is formulated as a combinatorial constrained optimization problem with non-linear and non-differentiable objective function. The IA based solving algorithm for OSD is proposed. Reliability, investment and outage loss, and the optimal number and location of switching devices of EDNs can be determined by the proposed algorithm. The test of RBTS-BUS6 and practical EDNs show that the proposed algorithm is suitable for switching optimization. The comparisons between IA and genetic algorithm(GA) for OSD are also illustrated. The numerical results prove IA to be good convergent.
