Power comes in two forms: alternating current (AC) and direct current (DC), each having its own applications and benefits. While the predominant form of electricity usage today is AC, both renewable sources including solar and fuel cells, and an increasing number of loads including LED lighting, high efficiency HVAC, data centers and electric vehicles are DC. In addition the distributed nature of these sources and loads requires increased use of distributed storage, such as lithium and flow batteries, that are also DC. The future interconnection of these DC sources, loads and storage will inevitably involve DC microgrids, where the costs, complexity and losses associated with AC grid connections are eliminated. ARDA Power is developing an innovative technology designed for commercial and industrial sites that can benefit from the use of flexible and scalable DC microgrids. Compared to other DC microgrid technologies, the plug-and-play nature of ARDA’s solution will result in a significant reduction of non-recurring engineering costs required for the design of a new system while preserving all of the cost and efficiency benefits of DC. This project will provide a proof-of-concept for the ARDA DC Microgrid system, demonstrating its plug-and-play nature via the use of standardized components, as well as its efficiency, its resiliency – in the form of back-up generation and extended battery storage, and its ability to shift AC grid load and operate on a stand-alone basis in the event of conventional grid failure.
