Abstract :
This paper presents a practical distribution state estimation (DSE) method and an optimal setting method for voltage regulators in distribution systems using modern heuristic techniques. The proposed DSE method utilizes hybrid particle swarm optimization (HPSO) and handles nonlinear characteristics of the practical equipment and actual measurements in distribution systems. The proposed optimal setting method for voltage regulators utilizes reactive tabu search (RTS) and enumeration method, and handles variation of load flow by introduction of distributed generation. The feasibility of the proposed methods is demonstrated on practical distribution system models
