ABSTRACT Fast charging of electric vehicles (EVs) with renewable energy is key to a cleaner and more sustainable transportation future, significantly reducing carbon emissions. However, the intermittency of renewable sources challenges reliable power supply during peak demand, while large‐scale fast charger integration can strain the electricity grid. To address these issues, this study proposes an analytical model for a photovoltaic (PV)‐powered fast‐charging station incorporating a flywheel energy storage system (FESS). A new control strategy is developed for simultaneous intermittency filtering and peak shaving, ensuring smooth PV output and stable power delivery. The fluctuation filtering strategy (FFS) leverages inclination angle measurements to mitigate solar variability, while the peak shaving strategy (PSS) regulates the voltage at the common AC bus. A dynamic relationship between FESS state‐of‐charge, filtering intensity and voltage regulation is also established. Results demonstrate that the proposed FFS effectively filters PV fluctuations without the memory effect or over‐smoothing seen in traditional moving average (MA) approaches. Meanwhile, PSS ensures voltage stability within operational limits. This simultaneous control approach enhances affordability, reliability and power quality, mitigating grid issues such as harmonic pollution, voltage fluctuations, instability and excessive stress on power conversion equipment — paving the way for scalable EV fast‐charging infrastructure.
