This research examines the feasibility of combining photovoltaic (PV) systems with flywheel energy storage systems (FESS) to maintain power generation even when PV systems are intermittent. The effectiveness and challenges of such integrations are evaluated by combining recent studies with industry experiences. One of the main advantages is that it compensates for intermittent power from PV systems by using FESS's fast reaction capabilities, ensuring a constant power supply. It highlights how the system might improve electricity stability, lessen reliance on unreliable renewable sources, and how high setup cost, limits on energy density, and integration difficulties can be mitigated by optimizing energy management using improved control systems. This integrated strategy is set to revolutionize sustainable energy solutions and provide a steady power supply regardless of solar power availability.
