Dc distribution system for home and office

Abstract

Direct current (dc) electrical distribution system has been very popular recently due to several advantages inherent in the system compared to conventional alternating current (ac) distribution system. Increasing number of dc appliances in our home and office, and the renewable energy generation which mostly generate dc are some of the reason. This project provides a design framework of dc powered house. Initially, Homer software is used to find the most optimum combination of electrical sources wheather a hybrid system or stand alone power sources system. Homer simulation result is used to implement and design the power electronics system. The design of the complete power electronics converter that intergates the source with the dc distributed system is done in Matlab/Simulink. Load test simulation is performed to show the effect of load changes. The simulation also shows the effect of the system with or without controller to regulate the output voltage.
