| description | The embodiment of the invention provides a method of dynamically optimizing an energy storage capacity of an optical storage micro-grid system. The method mainly comprises steps: according to forecasted photovoltaic power output and load power output, a power output curve of an energy storage battery is calculated, the maximal energy storage power value and the minimal energy storage power value of the energy storage battery in an entire sample data cycle are acquired, and an initial energy storage battery capacity for smooth fluctuation is further acquired; according to the total capacity of the energy storage battery, the minimal energy storage capacity value for emergency and the initial energy storage battery capacity for smooth fluctuation, a final energy storage capacity for emergency and the energy storage capacity for smooth fluctuation are determined. According to the embodiment of the invention, according to results of photovoltaic power generation output forecasting and load forecasting, the capacity ratio of power fluctuation for emergency and smooth grid site connection in the energy storage system is calculated, and dual effects of smoothing power fluctuation of the optical storage micro-grid system and the grid-connected sites and improving the energy storage utilization rate can be achieved. |
