Abstract

The solar thermal power station power prediction system comprises a meteorological monitoring and forecasting system The historical meteorological database, the meteorological data prediction system,the meteorological data prediction and correction system and the power station operation mode optimization system, a power grid dispatching system, a photovoltaic power station power generation powerprediction system and a photovoltaic power station control system; the meteorological monitoring and forecasting system, a historical meteorological database, a meteorological data prediction systemand a meteorological data prediction and correction system are used for monitoring and forecasting meteorological data, a power station operation mode optimization system and a power station operationmode optimization system, wherein the power station operation mode optimization system, a power grid dispatching system and a photovoltaic power station power generation power prediction system according to the forecast meteorological data, and the power grid dispatching instruction is used for optimizing the operation mode of the photo-thermal power station, and then the electricity generatingpower is predicted the photovoltaic power station control system controls the operation of the power station according to the operation mode parameters; the historical and current meteorological parameters are combined; the dependence of the prediction system on meteorological data of the meteorological station is reduced, and the operation cost of the system is reduced.

Description

technical field [0001] The invention belongs to the technical field of solar thermal utilization, and in particular relates to a power prediction system and an operation method of a solar thermal power station. Background technique [0002] Compared with photovoltaic power generation and wind power generation technology, a solar thermal power station (also known as a photothermal power station) equipped with sufficient heat storage capacity can stabilize the disturbance of external changeable weather conditions. With the aid of a scientific operation mode, the solar thermal power station can achieve continuous and stable Operation, therefore, is seen as one of the most promising renewable energy utilization technologies. [0003] However, during the operation of the solar thermal power station, due to the random changes in the direct solar radiation and the dynamic operating state of the solar thermal power station, the power generation of the solar thermal power station oft...
