Optimal Allocation of Electric Power Distributed Generation on Distributed Network Using Elephant Herding Optimization Technique

Abstract

This paper deals with optimal allocation of distributed generation in the electrical distribution system. Due to rapidly increasing energy demand on the distribution network, the system is experiencing disturbances like equipment overloading, voltage sags and swell. In this paper, the thermal and power loss constraints are considered for optimal operation. Elephant Herding Optimization (EHO) technique is applied for optimal placement and sizing of distributed generation on electric distribution network. The conventional optimization technique fails due to its complexity while solving the nonlinear problems. The EHO technique is tested on 5 bus radial distribution system. The intelligent and precise allocation of distributed generation in electric distribution network by using EHO reduces the overloading of the equipment, voltage swell & sag, active power, reactive power and production cost of electricity. Furthermore, the suggested optimization technique is expanded to 24 bus radial distribution and practical Indian system.
