Reserch of load modelling for distributed generation planning

YUAN Yue,QIAN Ke-jun(School of Electrical Engineering,Hohai University,Nanjing 210098,China)  
Increasing the penetration level of Distributed Generation(DG) into the distribution system is a new challenge for traditional electric power systems.Although it is generally recognised that DG has the potential of reducing energy losses in power systems,inappropriate modelling can lead to a misleading predictions for power loss reduction in DG planning.This paper presents an investigation into the impact of load models on the calculation of energy loss,and proposes detailed modelling of load in DG planning,where load is divided into three categories: residential,industrial and commercial.A comparative study of real and reactive power losses for various load models and load levels is carried out using the methodology proposed in this paper.A sample power system is adopted to analyse the system performance under various DG scenarios and at various load levels.Simulation results indicate that load models can significantly affect the load losses calculation in DG planning.
