A Novel Direct Approach to Load Flow for Distributed System using Voltage Stability Index

  Kanwarpal Singh,  Prof. Rajni Bala

Load flow has always been a critical problem and has been approached by several researchers. The techniques like Newton Raphson and Gauss Siedel works well but has severe computational disadvantages.The purpose of this paper is to analyse the voltage stability of electric power distribution system. A new method is established for computing voltage stability index (VSI) for each nodes of any distribution network. The most sensitive node is that node which having minimum value of voltage stability index. This paper proposes a novel direct method to load flow for distribution systems. The system has been simulated for constant power load considering losses. The methodology has been implemented on MATLAB R2013b and voltages of each bus are found out and real and reactive losses are calculated. Also the most sensitive node is found out. The results shows an improvement over traditional methods
