Embodiment Construction

[0052] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0053] A new energy generation power prediction system with an adaptive time scale, including: a numerical weather forecast receiving host, a local weather forecast host, and a power forecast host;

[0054] The numerical weather prediction receiving host is used to receive external weather forecast data from the meteorological department. The forecast time interval of external meteorological forecast data is fixed, usually every 15 minutes to half an hour.

[0055] The local weather forecast host is used to establish a weather forecast model through external weather forecast data and environmental monitoring data, and obtain refined local weather forecast data;

[0056]Local meteorological mod...

Abstract

The invention discloses a new energy power generation power prediction method and system with an adaptive time scale, including: step 1: perform power prediction at equal intervals according to external meteorological data; step 2: calculate adjacent power prediction results according to step 1 The absolute value of the power slope between two power prediction time points; Step 3: Perform nonlinear normalization processing on the absolute value of the slope; Step 4: Calculate the prediction time interval according to the results of the nonlinear normalization processing; Step 5: According to the step 4. Calculate the generated power data of each prediction point separately for the obtained prediction time interval. In the present invention, when the change trend of wind power and photovoltaic power generation is relatively large, the frequency of power prediction is increased; when the change trend of wind power and photovoltaic power generation is stable, the frequency of power prediction remains unchanged, which solves the problem that the existing prediction system has a fixed prediction time interval. Accurately reflect the changing trend of wind power and photovoltaic power generation.

Description

technical field [0001] The invention relates to the technical field of new energy power generation, in particular to a new energy power generation power prediction method and system with an adaptive time scale. Background technique [0002] New energy mainly includes: wind power generation, photovoltaic power generation. New energy power generation such as wind power and photovoltaics has the characteristics of strong intermittent, high randomness, and weak dispatchability. After large-scale connection, it will have a more obvious impact on the operation of the power grid. [0003] Wind power and photovoltaic power forecasting systems have become an indispensable part of the power system as a national mandatory requirement. It is of great significance to optimize the management of wind farms, optimize the operation and management level of wind farms, arrange maintenance plans reasonably, and improve the economic benefits of wind power and photovoltaic operating enterprises:...
