Embodiment Construction
[0067] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0068] The method for confirming the rate of the energy storage battery provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the grid system 10 communicates with the server 20 through a network. The server 20 receives the actual charge-discharge depth data, actual charge-discharge rate data, and actual cycle life data of the energy storage battery input by the user through the serial port line, analyzes them, and confirms the target rate of the energy storage battery. When the simulation system of the server needs...

The present application relates to a method, device, computer equipment and storage medium for confirming the rate of an energy storage battery. The method includes: performing data fitting on the actual charge and discharge depth data, the actual charge and discharge rate data, and the actual cycle life data of the energy storage battery, obtaining the mapping relationship between the rate charge and discharge times and the rate of the energy storage battery, using the mapping relationship and the energy storage The total cost of battery investment determines the cost of a single charge and discharge. According to the cost of a single charge and discharge and the rate, the target rate of the energy storage battery is determined, so that the target rate is used to charge and discharge the energy storage battery in batches without frequent charge and discharge. Extend the service life of the energy storage battery and increase the number of times the battery is used, thereby reducing the cost of a single charge and discharge and improving the overall benefit.
Description
technical field [0001] The present application relates to the technical field of energy storage grids, in particular to a method, device, computer equipment and storage medium for confirming the rate of an energy storage battery. Background technique [0002] It is an important function of the energy storage battery to participate in the frequency regulation of the power grid. Through its high-quality power regulation ability, it can effectively improve the operation status of the system. When the power disturbance occurs in the system, the frequency changes accordingly, and the conventional unit responds to the frequency through inertial response, primary frequency modulation and other means. Compared with conventional units, energy storage frequency modulation has the characteristics of quick response and flexible adjustment, and can provide faster and more effective power support in a short period of time. However, the existing energy storage frequency modulation operati...
