Analysis of Performance Enhancement for DC Distribution for Residential Distribution Network using hybrid AC DC Distribution Network

In the present times the use of DC loads is increasing rapidly. Depletion of fossil fuels like coal and petroleum is pushing us towards the usage of smart technologies by using renewable resources. This in turn results in the growth and usage of PV (photo-voltaic) cells for generation of DC electricity and DC micro grids. The implementation of dc micro grids provides an opportunity to integrate the renewable energy resources such as PV system and fuel cells without any need of converting into AC. The devices like computers, florescent lights, variable speed drives, households, business need DC power supply for their operations but all these need AC power conversions into DC for their use, and the majority of the rectifiers are inefficient. These DC- AC power conversion stages results in substantial energy losses and efficiency. In order to avoid this loss of energy and efficiency, a system has been implemented where DC can be directly supplied from a socket in residential buildings for DC loads, thereby reducing the loses due to AC-DC conversion, and for AC loads, the existing AC socket system is to be used.
