The invention discloses a wind-light-water-fire storage system power smooth control method and system, and the method comprises the steps: carrying out the spectral analysis of the real-time fluctuation power of a wind-light-water-fire storage system through obtaining the prediction data of wind power and photovoltaic power, and correcting the filtering cut-off frequency; and after a power control signal for stabilizing the high-frequency component, a power control signal for stabilizing the low-frequency component, a thermal power adjustment amount and a hydroelectric power adjustment amount are calculated, the system voltage is calculated according to the power control signal for stabilizing the high-frequency component, the power control signal for stabilizing the low-frequency component, the thermal power adjustment amount and the hydroelectric power adjustment amount. And when the voltage reaches a preset condition, a control target is sent to each power generation unit for power generation. By using the
