Setting up of Chinese Wind Power Prediction System

The experience in advanced wind power countries indicates that wind power forecasting (WPF) technology is one of the effective measures to mitigate peak-load regulation pressure, reduce reserve capacity and increase wind power accommodation capacity for power grids. Recently, the leading countries in wind power in Europe and the United States have already established impeccable management mechanism in WPF, and their forecast is performed both in wind farm side and dispatching facility side. But in China, the WPF systems, though, are popular in dispatching side; the WPF systems in wind farm side are still blank. This report, combining the international experience and national situation, studies on the tailor-made wind power forecasting system framework and implementation plan in China. Based on the deep investigation of international experiences and the complete analysis of the main responsibility of the shareholders, combining the current status of the WPF technologies in china, the research proposes a tailor-made framework and implementation plan of the wind power prediction system with Chinese characteristic. The research results will develop the advantages of all the participants to boost the development and application of WPF technology.

Development of Short-term Wind Power Forecasting System for Inner Mongolia Power Group

A wind power prediction system is installed for the Inner Mongolia Electric Power Group (IMPG), and a one-year short-term wind power prediction service is provided by the project. The system includes a total of 8 wind farms with the total installed capacity of 756.1MW. The set of wind power prediction system can be applied directly to the planning of the power grid dispatching department, which helps to reduce the negative impact of wind power, and improves the security, stability and economy of the grid operation; Meanwhile, through comparation with international forecasters, the various factors that affect the prediction accuracy are analyzed to improve the accuracy of prediction results, the existing prediction models and algorithms are evaluated and the forecasting techniques are continued to be improved to narrow the gaps with similar international systems. The project is underway currently.

Establishment of Wind Turbine Certification Capabilities (China Classification Society)

The project aims to establish the WTGS model certification and project certification capacities, according to the quality and safety standards of the international WTGS. The model certification includes the design assessment, quality management assessment and the prototype testing from the design institutions. The project certification is based on the model certification, including the wind farm site assessment, wind turbine assembly monitoring, wind turbine transportation, installation, witnessing the inspection, and the regular monitoring. The model certification and project certification are the important foundation of China’s wind power industry competing in the domestic and overseas markets. The stage tasks of the project are to establish and improve the technology rule system of the wind turbine model certification, to make the wind turbine model certification approved by CNCA; and the wind turbine model procedure approval of CNAS can be obtained.
