Abstract

The present invention provides a method for smoothing output of a solar-thermal power station, comprising: obtaining a data set composed of power prediction values ​​of a solar-thermal power station; using a polynomial fitting algorithm to fit the data set to obtain an ideal smooth output formula; according to the ideal The smoothed output formula calculates the ideal smoothed output value; the actual smoothed output value is determined according to the magnitude relationship between the ideal smoothed output value and the predicted power value of the solar-thermal power station. In the present invention, polynomial fitting is performed on the power prediction value of the solar-thermal power station in the entire planned output range, and the actual smooth output curve finally obtained will not lag behind. method, the present invention has a more optimized smooth output effect.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method for smoothing power output of a photothermal power station. Background technique [0002] The solar thermal power station adopts the "light-heat-electricity" power generation method based on the principle of solar thermal power generation, and reflects sunlight to the surface of the heat absorber on the top of the solar tower through thousands of heliostats to form a high temperature, and then Steam is generated through the heat transfer medium to drive the steam turbine to generate electricity. Compared with photovoltaic power plants, solar thermal power plants have a lower cost of power generation and have developed rapidly in recent years. [0003] Solar energy is currently a relatively mature renewable clean energy that can be used for power generation, but due to the randomness and volatility of solar energy resources, it brings a series of impacts on the p...
