Abstract:This report proposes the technology of a DC-Microgrid as a solution for the energy transition of a gas station. Some of the major concerns addressed by this alternative are the environmental impact caused by the insertion of Electric Vehicles (EVs), the resulting shortage of public charging infrastructure for the users, and the technical limitations of the current electrical infrastructure. Extensive research on the building blocks of a Microgrid was summarized. Then, four Microgrid designs were dissected and reflected upon. Finally, a step-by-step design process was described for a DC-Microgrid capable of providing fast DC-charging and single-phase AC-charging with a maximum output power of 50 kW and 7.4 kW respectively. This power is provided by a mixture of Distributed Energy Resources (DER). The mean power demand is covered by the grid and a PV-module arrangement while the Energy Storage System (ESS) deals with the peak power demand. MATLAB was used to calculate the most optimal values for some of the proposed specifications such as the size of the ESS, energy demand, and power demand. The proposed solution was found to be a great alternative for the future of energy distribution. It is preferred for the insertion of renewable energy resources due to the fewer transformation steps required. And its superior controllability of power flow and power level allows for increased output powers while maintaining high safety and relatively low costs.
