Multi objective Optimization for Enhancement of Technical-economic and Environmental Benefits of Radial Distribution Networks using GTO algorithm

Abstract

In a Modern electric distribution utility structure, create a new opportunities and technological innovations for development of existing Radial Distribution System (RDS). Integration of DG based on PV panel and DSTATCOM with RDS provides more benefits interims of technically, economically and environment point of view. From the background, this paper maximizes the technical, economical and environmental benefit of RDS by proper sitting and sizing of DG and DSTATCOM in a combined manner. The benefits such as are Active Power Loss Level (APLL), Short Circuit Level (SCL), Voltage Deviation Level (VDL), Net Saving Level (NSL), and Environmental Pollution Reduction Level (EPRL).are taken in account. This problem consider as a Multi-Objective Optimization Problem (MOP) and solved by an innovative best metta-heuristic approach of Group Teaching Optimization (GTO) algorithm. The GTO effectively identify the optimal location and required value of DG and DSTATCOM by various phases of GTO..This paper also improves the voltage profile and reduces the network losses in RDS. Case study with IEEE 33 system is consider and simulated results are tabulated. The output results are compared with other similar approaches and reported in literature.
