Embodiment 1

[0101] The present invention proposes a medium and long-term new energy resource database construction method based on multi-source data reanalysis technology. The overall technical route is as follows figure 1 and 2 As shown, there are 4 steps:

[0102] Step 1: Obtain traditional meteorological data (conventional weather stations, satellite data, etc.) and new energy meteorological data (wind measurement data, photometric data); obtain FNL, CFSR, and MERRA climate reanalysis data with coarse global temporal and spatial resolution. Construct multi-source input datasets suitable for climate reanalysis techniques.

[0103] (1) Multi-source database construction

[0104]This method uses observation data to carry out data assimilation in climate numerical simulation, and uses meteorological devices installed in new energy stations to obtain historical monitoring data of wind, irradiance and other resources in new energy stations in RWD format; using World Meteorological Organiza...

Abstract

The invention relates to a medium-and-long term new energy resource database construction method and system, and the method comprises the steps: carrying out the climate data simulation based on a pre-constructed multi-source meteorological data assimilation database and a re-analysis database, and generating a climate simulation data set; and integrating the climate simulation data set accordingto a preset classification scale to generate a medium-and-long-term new energy resource database. The medium-and-long-term new energy resource database construction method based on the multi-source data re-analysis technology is used for predicting the medium-and-long-term distribution condition of new energy resources, supporting large-scale development of new energy and avoiding a large amount of wind curtailment and light curtailment.

Description

technical field [0001] The invention relates to the field of new energy power generation, in particular to a method and system for constructing a medium- and long-term new energy resource database. Background technique [0002] New energy sources such as wind power and photovoltaics use wind energy and solar energy resources as the driving force. Forming a new energy resource database is the basis for mastering the operating characteristics of new energy and doing a good job in new energy consumption and management. However, the new energy resource database has not yet been established and analyzed. The evaluation work is not deep enough, and the phenomenon of wind and solar abandonment occurs frequently, which has a certain impact on the operation and management of new energy. [0003] Scientific evaluation of resource status has become an important link in the current new energy operation management that needs to be improved. Only by scientifically evaluating the resource ...
