Embodiment Construction

[0027] The present invention is described in further detail below in conjunction with specific embodiments, but is not intended to limit the present invention.

[0028] The photovoltaic power generation output power prediction system includes a database server, a numerical weather forecast processing server, a power prediction server and a user interface server connected to the database server. The database service realizes the storage and interaction of data. The numerical weather forecast processing server downloads the numerical weather forecast data from the internet network, and generates the meteorological element data of the required forecast time period, and stores the data in the database server. The power prediction server retrieves the meteorological element data, and processes the output power of the time period in which the meteorological element data is generated. The user interface server retrieves the processing result of the power prediction server from the d...

Abstract

The invention discloses a power generation output power prediction system of a photovoltaic power station. The power generation output power prediction system comprises a database server, a numerical weather prediction processing server, a power prediction server and a user interface server, wherein the database server is used for performing storage and data interaction of data; the numerical weather prediction processing server is used for processing numerical weather prediction data downloaded from a network to generate meteorological element data of a prediction time interval at the place where the photovoltaic power station is positioned and transmitting the meteorological element data into the database server; the power prediction server is used for calling the meteorological element data from the database server, obtaining power generation output power of the photovoltaic power station at the prediction time interval corresponding to the meteorological element data according to relation of the meteorological element data and the output power and transmitting a result into the database server for storage; and the user interface server is used for calling a processing result of the power prediction server from the database server to realize interaction with a user. The system provided by the invention is simple and practical and has high accuracy.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a photovoltaic power station power generation output power prediction system. Background technique [0002] Solar photovoltaic power generation is a form of power generation that uses the photovoltaic effect of solar cells to directly convert solar radiation energy into electrical energy. At this stage, the promotion and application of solar energy is increasingly showing an emerging world trend, and the solar energy industry has become one of the new energy industries that are booming in the world. The development and utilization of clean, safe and environmentally friendly solar energy has become a common choice for human society to alleviate the increasing energy shortage and a living force to control severe environmental pollution. The stable operation of the power grid needs to maintain a certain balance between the supply and demand sides, that is, acc...
