AI Technical Summary

Technical Problem

The existing control methods of photoelectric power stations fail to effectively consider the impact of discharge of energy storage systems on the power prediction system, resulting in a large deviation between the actual output of the photoelectric power station and the prediction curve.

Method used

By predicting the photovoltaic power curve and the energy storage power curve, the deviation value between the actual curve of the power of the photovoltaic power station and the prediction curve is calculated, and the charging and discharging process of the energy storage unit is adjusted according to the deviation value to reduce the influence of the photovoltaic power generation power deviation.

Benefits of technology

This method reduces the deviation between the actual output of the photovoltaic power station and the prediction curve, and uses the adjustment function of the energy storage system to further reduce the error of the actual power generation power of the photovoltaic, making the actual output of the photovoltaic power station closer to the prediction curve.

Abstract

The invention discloses a regulation and control method of a grid-connected optical storage power station, a storage medium and computer equipment. The regulation and control method comprises the following steps: predicting a photovoltaic power curve and an energy storage power curve of the optical storage power station according to a predetermined strategy; obtaining a power prediction curve of the optical storage power station according to the photovoltaic power curve and the energy storage power curve, wherein the power prediction curve of the optical storage power station is used as the target power of the optical storage power station; obtaining an actual power curve of the optical storage power station and calculating a power deviation value between the actual power curve of the optical storage power station and the power prediction curve of the optical storage power station; and adjusting the charging and discharging process of an energy storage unit in the optical storage power station according to the power deviation value. According to the method, the influence of the energy storage system is considered, the deviation between the preliminarily predicted power curve and the actual power curve of the optical storage power station is reduced, and then the influence caused by the error of the actual photovoltaic power generation power is further reduced by using the adjusting function of the energy storage system, so that the actual output of the optical storage power station is closer to the power prediction curve.
