Since DG units have a small capacity compared to central power plants, the impact is minor if the penetration level is low (1%-5%). However, if the penetration level of DG units increases to the anticipated level of 20%-30%, the impact of DG units on voltage stability will be profound.This paper discusses some important aspects related to maximum loadability in electrical power systems. The effectiveness of the analyzed method is demonstrated through numerical studies in IEEE 14 bus test systemand an optimal location of wind farm is determined using particle swarm optimization.
