Smart Controller Design for Solar Grid Integration and LVDC Distribution System

Nowadays Direct Current (DC) Distribution Systems have started to attract a lot of attention as they offer a natural interface to generation and consumption units such as renewable energy sources, energy storage systems and end-user electronic loads. However, a number of technical challenges related to integration of renewable energy sources and their control must be overcome. This paper presents a smart controller based design for efficient and cost effective operation of a LVDC Distribution System. This paper mainly focuses on solar energy as it is the most abundantly available renewable energy source. This paper basically presents a smart controller based design for cost effective operation of solar-grid tied LVDC system. The control strategy used in this system helps to achieve the maximum efficiency as utilization of dump power is also considered. This system is defined to fill the necessity of regions where solar power is used only as backup purposes to charge the battery and is actively dumped during the presence of active grid. The system has been tested for a solar panel with a battery backup storage and its effectiveness has been observed. The battery backup is made to operate during the Grid cutoff. 
