Optimal penetration of renewable sources for distribution system performance improvement

In recent years the integration of renewable energy sources to distribution system is gaining attention worldwide. However, the intermittent nature of renewable sources creates challenges in integration of Distributed Generation (DG) units. In this paper, a Genetic Algorithm (GA) based methodology has been proposed for optimal penetration of different types of renewable DG units in the distribution system for minimizing annual energy loss and improving the voltage profile considering the intermittent nature of renewable DG units and load. The simulation results verify the suitability of the proposed methodology for all operating scenarios.
