Optimized operation method considering mirror field area and heat storage capacity of photo-thermal power station

Abstract

The invention particularly relates to an optimized operation method considering the mirror field area and the heat storage capacity of a photo-thermal power station, and the method comprises the steps: combining an optimal load reduction model of an electrothermal coupling system and a multi-state reliability model of the photo-thermal power station based on the photoelectric capacity ratio, the heat storage time and the load loss cost of system load reduction of the photo-thermal power station; establishing an optimal configuration model considering the mirror field area and the heat storage capacity of the photo-thermal power station; performing clustering processing on direct solar radiation data, namely DNI data, of the photo-thermal power station through a hierarchical clustering method; and solving an optimal configuration model considering the mirror field area and the heat storage capacity of the photo-thermal power station by combining a particle swarm algorithm with the clustered DNI data to obtain a corresponding model optimal solution result, and applying the model optimal solution result to the optimal operation of the photo-thermal power station. According to the method, the mirror field area and heat storage capacity parameters of the photo-thermal power station are incorporated into operation optimization planning, so that the influence of the parameters of the photo-thermal power station on the overall reliability of the system can be considered on the basis of ensuring the operation economy of the system.

Description

technical field [0001] The invention relates to the technical field of photothermal power generation, in particular to an optimized operation method taking into account the mirror field area and heat storage capacity of a photothermal power station. Background technique [0002] Solar energy is in an important position in the development of renewable energy because of its breadth and sufficiency. Meanwhile, solar thermal power generation is also one of the important foundations for large-scale power generation of renewable energy in the future. Looking at the development history of solar thermal power generation technology for more than 30 years, it has made great progress in the aspects of concentrating light tracking, heat collection, transmission, storage, and conversion, and is developing towards industrialization and large-scale development. However, due to the late start and commercialization is not common, CSP still faces high investment costs. Therefore, in order to...
