GA based Simultaneous Optimization of hybrid Distributed Generation in the Power System Network

The distribution system in the Power System network is to provide excellent Power supply to the consumers. Due to increase of power demand in present scenario, hybrid power generation have been increased in distributed system, so small DG units are placed to improve the voltage profile through various loads connected to feeders. Wind/solar alone does not fulfil the requirement of uniform voltage to load because it is intermittent in nature so DG along with diesel generator will be required to have maximum benefit. An intelligent technique that employs GA approach to achieve the objective function. The voltage stability index would determine the candidate bus for optimal location of these devices. This approach is tested on IEEE 57 bus system and Indian utility system NTPS 17 bus system with different types of loads through the feeders.
