Wind power cluster prediction method and device

Abstract

The invention provides a wind power cluster prediction method and device. The wind power cluster prediction method comprises the steps of selecting a numerical weather prediction point location according to a pre-divided wind farm region; building a regional power prediction model according to the numerical weather prediction point location; and calculating a power prediction value of the power grid according to the regional prediction model. The wind power cluster prediction device comprises a selection unit, a calculation unit and a modeling unit. The technical scheme provided by the invention can accurately and comprehensively predict the regional wind power, and provides reliable technical support for improving the wind power absorption capacity of the whole province.

Description

technical field [0001] The invention relates to wind power cluster forecasting technology, in particular to a wind power cluster forecasting method and device. Background technique [0002] The difference between wind power and conventional energy is the randomness and intermittent nature of wind power. With the increase of wind power installed capacity, the power grid dispatching department must deploy a wind power forecasting system to ensure the safety and stability of the power system and guide the formulation of dispatching plans. [0003] Wind power forecasting is a technology to predict the fluctuation of wind power in the future by establishing a mathematical model. The existing wind power forecasting system takes a single station as the prediction object, and the wind power prediction results of administrative provinces are obtained by accumulating the prediction results of single stations. . However, the construction speed of wind farms across the country is fast ...

AI Technical Summary

Problems solved by technology

However, the construction speed of wind farms across the country is fast and the basic conditions are uneven. The wind power prediction method with a single station as the prediction object is difficult to accurately cover the wind power prediction of each administrative province. The start-up plan was made, so the key to improving the wind power consumption capacity is to overcome the current situation of insufficient coverage of wind power forecasting on the dispatching side. Therefore, it is necessary to provide a technology for establishing a wind power area forecasting model to achieve rapid coverage of grid-connected wind farms across the province. plan
