Analysis of voltage stability in radial distribution system for hybrid microgrid

Abstract

The hybrid microgrid is growing in India for rural electrification due to potential benefits in providing shape, reliable and sustainable electricity from renewable energy resources. As we know, the renewable energy resources are depending on nature and on the other hand, the loads on microgrid are variable. Due to instability in generation and load, voltage instability problem occurs. In this paper, we are discussing voltage stability by radial distribution network in microgrid with computational recursive method and implementing load flow analysis on 10-node system with simulation approach for voltage stability index (VSI). The critical node in microgrid is identifying with help of VSI.
