Source storage cooperative control method and system for stabilizing power fluctuation

The invention provides a source storage cooperative control method and system for stabilizing power fluctuation, and the method comprises the steps: predicting the photovoltaic power generation power, and obtaining the predicted value of the photovoltaic output power at each moment before the day; processing the obtained prediction result and taking an obtained power curve as a grid-connected reference power curve; comparing the real-time operation data of the power station with the grid-connected reference power to obtain fluctuation power; after the fluctuation power exceeds the grid-connected standard, when the forward grid-connected fluctuation power at the sampling moment exceeds a set value, the photovoltaic working mode is switched to a power-limited operation mode, and the photovoltaic working mode is switched to a maximum power point tracking mode after working until output returns to normal; when the reverse grid-connected fluctuation power at the sampling moment is out of limit, the photovoltaic po
