Benefit Evaluation of Solar Thermal Power Generation in Qinghai Power Grid from the Perspective of Absorbing Capacity of other New Energy Sources
Vigorously developing new energy power generation is an important goal for the development of China's power industry,but only relying on wind power and photovoltaic to complete the consumption ratio of new energy requirements will lead to a high rate of power abandonment.The heat storage link of solar thermal power generation has the ability to adjust,and the use of solar thermal power generation instead of wind power and photovoltaic can reduce the rate of wind power and photovoltaic power abandonment,while playing the capacity benefit,reducing the installed scale of thermal power and coal consumption.However,the high cost of solar thermal power generation limits the development of solar thermal power generation.How to evaluate the benefits of solar thermal power generation in the power system is of great significance to the development of solar thermal power generation.This paper proposes a method for evaluating the benefits of solar thermal power plants under the constraint of equal new energy consumption capacity,which can comprehensively consider the replacement benefits of new energy installed in solar thermal power generation,reduce the capacity benefits of thermal power installed,and reduce the coal consumption benefits of thermal power generation,so as to comprehensively evaluate the benefits of solar thermal power generation in the system.The research results can provide reference for the benefit evaluation of solar thermal power generation in Qinghai Province.
