Peak Shaving Control of EV Charge Station with a Flywheel Energy Storage System in Micro Grid

In this study, peak shaving control is applied for load balancing using micro grid and flywheel energy storage system (FESS). The proposed method is applied to an EV charge station with an unbalanced load curve. FESS is charged during the low energy demand period and discharged during the high energy demand period. The FESS is determined by considering the required energy capacity, input power, and output power. When the Peak shaving control has been performed using the specified FESS, it has been noticed that an unbalanced load between 7 and 230 kW could be successfully balanced. It has been observed that the balanced load fluctuates between 13 and 123 kW. Thus, a more balanced load demand for the EV charge station has been generated from the electricity grid.
