The present invention discloses a new energy power station auxiliary power prediction and generation power application method and system. For a photovoltaic new energy, a three-layer distributed architecture is employed to carry out auxiliary power prediction and power generation application, through establishing an auxiliary power prediction and power generation application architecture with the basis of a unit layer, a matrix layer, and a plant station layer in a new energy plant station, the problem of low timeliness caused by a condition that the current large scale new energy power station power prediction is not high and plant station AGC system power generation distribution is lack of individual difference pertinence is solved as to improve the prediction accuracy of a new energy power station power prediction system and the rationality and economical efficiency of each matrix power distribution by a plant station AGC system, and the improvement of the economic operation level of the new energy plant station is facilitated.
Description
technical field [0001] The present invention relates to the field of new energy power generation automation, in particular to a method and system for new energy photovoltaic power prediction auxiliary power prediction and power generation application applied in large-scale new energy photovoltaic power plants. Background technique [0002] With the promotion of renewable new energy, especially photovoltaic new energy power generation technology in China, the power generation capacity of new energy and its proportion in the entire power grid have increased significantly. The current power prediction system in new energy plants and stations is based on numerical meteorological weather forecast data and a small number of individual weather instrument sensor data distributed in the photovoltaic area, combined with historical power generation data of some plants and stations, to predict and calculate the photovoltaic power generation value of the entire station. The current power...
