基于“双碳”目标的光热电站调峰能力规划研究

Driven by the dual carbon target, China's new energy will develop more rapidly with the tenser system peak shaving capacity and the more accelerating demand for the peak shaving power supply. As a self-contained heat storage new energy power station, the exertion of the peak shaving capacity of a solar thermal power station is of far-reaching significance for promoting new energy consumption. Therefore, the system peak shaving demand of the system should be fully considered for the heat storage capacity and the concentrated heat collection configuration of the solar thermal power station. Firstly, based on the characteristic parameters of the new energy, the consumption objectives and the actual dispatching operation experience, this paper improves the traditional net load curve and puts forward the measurement indexes of the system peak shaving demands such as the equivalent minimum load rate and the equivalent daily load rate. Then, the peak shaving capacity of the solar thermal power station is planned and studied from the perspective of the whole system and a configuration of the main technical parameters of the solar thermal power station is proposed. Finally, the effectiveness of this method is verified by a simulation example of an actual power grid in Northwest China. The research conclusion will provide a reference for the evaluation of peak shaving capacity of the power system and the optimal design of the solar thermal power station project.
