Abstract: Electric power consumption is on the rise. Electrification of transportation, houses, offices and more continues worldwide. These loads and sustainable sources have one thing in common: Direct Current. To successfully respond to this growing usage of direct current (DC) systems it is important to provoke an evolution in the provision of DC infrastructure. At present, there are doubts about the safety, efficiency, reliability and economical aspects of DC grids. Even when considering the implementation of a DC grid there is still confusion on parameters such as used voltages, converters or plugs.
In this paper, optimal parameters are defined for a DC Micro Grid design, mainly focusing on student and domestic environments. But also office spaces, industrial and agricultural environments can use the same basic parameters. The proposed parameters are evaluated on their sustainable impact and benefit. This paper proposes a 350 VDC micro grid, based on its energy efficiency, savings of raw materials and an improved reliability. Connecting electronics consuming less than 100 W is possible by the development of a smart plug close to the consumer. This plug, based on USB Power Delivery, is able to apply a variable voltage determined by the device, communicate with other connected devices and act as a smart breaker at the load.
These proposed parameters are a guide for future work and standardization of concepts for DC grids. The guidelines can be used in future DC initiatives in order to guarantee safety and efficiency.
