1. A method of predicting electrical wind power output for one or more wind turbines comprising:
- measuring first wind speeds at wind speed sensors over a first period of time;
converting the first wind speeds to first electrical power data;
determining weights for each data point in the first electrical power data for each corresponding one of the wind speed sensors based on the first electrical power data and published wind power data for a region encompassing the wind speed sensors;
measuring second wind speeds at the wind speed sensors over a second period of time;
converting the second wind speeds to second electrical power data; and
generating weighted electrical power data by multiplying the second electrical power data by the corresponding weights.

Abstract
This disclosure describes systems, methods, and apparatus for predicting electrical power output from wind farms using statistical methods and measured wind speeds near boundaries of control volumes that encompass the wind turbines of interest. These systems, methods, and apparatus can provide electrical power output predictions of up to 6, 12, 24, or 48 hours in advance of actual power reaching the grid.

17. A system comprising:
-
a memory for storing; first wind speed data for a first time series, measured by a plurality of wind speed sensors; and second wind speed data for a second time series, measured by the plurality of wind speed sensors; a power conversion module configured to convert the first and second wind speed data into first and second electrical wind power output data; a weighting module that; determines a weight to assign to each wind speed sensor; and multiplies each weight times a portion of the second electrical wind power output data associated with each weight to produce weighted electrical wind power output data; and a summation module that sums the weighted electrical wind power output data for the plurality of wind speed sensors. - View Dependent Claims (18, 19)
