Statistical Impact Analysis of Integration of different types of WTG on Radial Distribution System

A nation's ability to obtain electrical energy determines its socio economic progress. While keeping in mind different operational and technological restrictions, planning for distribution system expansion considers the services that must be installed for the distribution networks to manage the expected load demand. When distributed generation sources (DGs) are integrated, distribution network efficiency is increased, power losses are decreased, and voltage magnitude is also enhanced. In this paper, Wind Turbine Generator (WTG) as renewable energy source of four different types are integrated under two unique control scheme in conventional radial distribution topology. A statistical analysis of WTG integration is carried out for conventional 34 bus radial distribution system using ETAP simulation package on single and multiple locations. Voltage magnitude were analyzed under critical, marginal and nominal level before and after integrating DGs in test system. In addition to this loss reduction is also noted and analyzed while incorporating different types of WTGs.
