NOVELTY - The method involves obtaining a penalty measurement for wind power change of rate. A forecasted wind power production, an actual wind power production from a wind power producer, a variable price of power measurement, a power storage battery state and capacity measurement and the penalty measurement for wind power change of rate are analyzed to determine a consistent rate at which wind power is to be exported from the wind power producer to a grid. Power is exported to the grid at the determined consistent rate for smoothing a wind power output from a wind farm.    USE - Method for smoothing a wind power output from a wind farm to a grid.    ADVANTAGE - The method enables wind generators to make active participation in day-ahead markets by facilitating quoting of an accurate amount of power and price based on a wind power curve output and in real-time (RT) markets by outputting power at a piece-wise constant rate, thus providing increased or maximized revenue for wind produced in an economical-efficient manner, and hence enabling independent system operators (ISOs) to utilize more green power and reducing dependence on non-renewable sources of power. The method enables the forecasted wind power production, the actual wind power production from the wind power producer, the variable price of power measurement, the power storage battery state and capacity measurement and the penalty measurement for wind power change of rate to be analyzed to determine the consistent rate at which wind power is to be exported from the wind power producer to the grid so as to export the power to the grid at the determined consistent rate, thus smoothing the wind power output from the wind farm in a cost-effective manner.
