Summary: This paper proposes a multi-hour ahead wind power forecasting system, which includes a physics-based model, a multi-criteria decision making scheme, and two artificial intelligence models. The system utilizes a WRF model for wind speed forecasts, constructs a 5-in-1 ensemble WRF model using a TOPSIS scheme, and employs ANFIS models to correct wind speed forecasts and determine a power curve model. Validation using historical wind speed data from a wind farm in China demonstrates that the system provides good wind speed and power forecasts for 30-min to 24-h time horizons.

Summary: Wind speed is the main meteorological factor affecting wind turbine power generation. Existing wind speed fluctuation division algorithms only consider the wind speed changing process, but there is strong uncertainty in the wind speed-power conversion, which follows a multi-power transfer relationship under wind speed fluctuation. Therefore, a wind speed power transfer fluctuation partitioning (PTFP) algorithm is proposed to refine wind power forecasting by considering both the wind speed variation and power transfer characteristics.
