Model correction based wind power forecasting system and method

Abstract

The invention relates to a model correction based wind power forecasting system and a method. The model correction based wind power forecasting system comprises a numerical weather forecasting server, a fan, an anemometer tower, a wind power forecasting server, a database server and a wind power forecasting system client. The model correction based wind power forecasting method comprises the following steps: firstly using a numerical weather forecasting model provided by the meteorological department to forecast the weather situation of a wind power plant, and then building a real-time forecasting model, and converting the forecasting value of the numerical weather forecasting model to power output of the wind power plant. The system and the method are adopted to reduce various model errors and ensure the accuracy rate of forecasting results.

Description

technical field [0001] The present invention relates to a wind power forecasting system and method, in particular to a model correction based wind power forecasting system and method. Background technique [0002] During the period when the installed capacity of newly-added wind farms in my country is rising rapidly, the development of the wind power industry has caused difficulties to the safety and dispatch of the power grid. In order to meet the needs of the power grid and improve the utilization efficiency of wind power, relevant national departments have issued a series of standards and requirements, and it is imperative to install and use wind power forecasting systems in various large wind farms. [0003] At present, the development time of my country's wind power industry is relatively short, and the main wind power forecasting methods and forecasting systems in the industry are in the initial stage of exploration and development. According to the regulations of rel...

[0007] 2. Use the manufacturer's guaranteed wind turbine power curve to predict the power of the wind farm: In the actual wind farm, there are differences between the actual power curve and the theoretical power curve of the wind turbine, which is mainly due to the actual wind farm operating conditions of the wind turbine and the theoretical test conditions. There are large differences in working conditions. In addition, the nacelle wind speed power curve (NACP) of the fan is also different from the actual power curve. In some wind power forecasting systems in the industry, the power curve provided by the manufacturer is directly used for prediction, and the accuracy of the result is difficult. ensure
