Exponential Based Load Model for Baghdad Distribution Feeder

Abstract

Distribution feeders in Baghdad comprise different load classes, those classes differ in load component, characteristics and sensitivity to network variables. In view of this fact, applying any dynamic study to those feeders requires proper modeling of loads, otherwise, unfavorable results obtained. Realistic load component varies in relation to both system voltage and frequency, and this variation is related to load type and sensitivity, that may alter studies by deliveringnon -desired results. Proper modeling leads to desirable decisions,correct and realistic results, and undoubtedly will reduce efforts and expense of the un-justified network modifications. In this work, residential load mix feederisstudied,the load characteristic is acquired, and thennetwork componentsand loads are presented using voltage-frequency dependable exponential load model. The results obtained arerecommended to be implemented in distribution network studies and dedicated software within Baghdad network.
