A Renewable Based Direct Current Building Scale Microgrid

This renewable-based direct current (DC) microgrid will connect on-site generation with loads and provide a low cost, energy-efficient solution to save costs. Solar PV will be directly connected to energy-efficient DC lighting, DC energy storage systems, and ventilation on a 380 V DC bus to form a DC building microgrid. This microgrid system proposed for the Honda Distribution Center in Chino, California reduces the need for inverters for PV and rectification equipment in the loads, thus improving the overall utilization of solar energy by 7-10% as compared to conventional AC systems, while lowering component complexity and costs.
