Analysis of Radial Distribution System Optimization with Facts Devices Using Hybrid Heuristic Technique

Distribution networks transport electric energy to the end user from distribution substations. Power utilities are looking for improved power delivery performance. The performance of the delivery system is measured by the power loss of the system. The increase in power loss increases the operating cost of the distribution system. This paper presents an algorithm to minimizing the power loss of the distribution system. Self Adaptive Hybrid Differential Evolution (SaHDE) technique combined with sensitivity factors has been practiced to find the optimal location and the size of FACTS devices to reduce the operating cost of Radial Distribution System (RDS). The locations of the FACTS devices are located by the sensitivity factors. The amount of reactive power component generation/absorption by the FACTS devices at the identified locations has been calculated through SaHDE. The effectiveness of the proposed technique is validated through 10-bus, 34-bus and 85-bus radial distribution systems.
