The invention discloses a prediction method for the charging and discharging capacity of an energy storage power station and a power supply method of the energy storage power station. The prediction method comprises the following steps of: determining a charging and discharging start date, a charging and discharging start time point and duration of an energy storage power station prediction target; determining the type of the charging and discharging start date; determining n dates of the same type as the charging and discharging start date, acquiring data of time points corresponding to n dates, and then performing mean value processing to obtain a predicted chargeable / dischargeable capacity; obtaining corresponding chargeable / dischargeable power according to the chargeable / dischargeable quantity predicted at the charging and discharging start time point and the duration time; and if the chargeable / dischargeable power is smaller than the corresponding rated power of the energy storage power station, keeping the predicted value of the chargeable / dischargeable power unchanged, otherwise, updating the predicted value of the chargeable / dischargeable power into the product of the corresponding rated power and the duration. The prediction method and the power supply method provided by the invention are more accurate in charging and discharging prediction, so that the peak load shifting operation mode of the energy storage power station is more efficient.
Description
technical field [0001] The invention relates to the technical field of charging and discharging of an energy storage power station, in particular to a method for predicting the charging and discharging capacity of an energy storage power station and a power supply method for the energy storage power station. Background technique [0002] my country's electricity supply and demand are generally loose, but more and more local areas begin to experience electricity shortages during peak hours of electricity consumption. Demand response means that when the power supply is tight, the power grid is seriously faulted, or the safety and reliability of the system is at risk, after receiving the service compensation notice of inductive load reduction, the power user changes the inherent power consumption habit and reduces or postpones the power consumption for a certain period of time. Load, so as to ensure the short-term behavior of safe and stable operation of the power grid. Althou...
