Modeling and Simulation of DC distribution system based on Photovoltaic Energy Conversion System for home LED lighting

The practical effectiveness of DC distribution system and efficieny of LED lighting system makes them a highly feasible solution for home lighting requirements. A DC distribution system having a integrated Photo Voltaic Energy system running LED light load for an average Korean house is modeled using Simulink/SimPowerSystems. An AC to DC convertor and a PV charge controller running Maximum Power Point Tracking algorithm is designed. Power efficiency and performance of the LED lighting system is evaluated and compared with conventional AC lighting system. The benefits of using PV system are highlighted.
