Performance Analysis of Unbalance Radial Feeder with Time Varying Composite Load

Abstract

The focus of this paper is to present performance indices for unbalance radial feeder having dif-ferent characteristic and composition of time varying static ZIP load models. These provide a framework for benchmarking of distribution automation projects. 15 minutes characteristics time interval for load flow and load modeling are considered to meet smart grid implementation crite-rion. A forward-backward sweep method is employed for load flow solution. Developed perfor-mance indices were illustrated on modified IEEE 37 node test feeder. Performance indices are useful for analysis, operational, planning and integration of stochastic renewable sources.
