Method of coordinating and stabilizing the delivery of wind generated energy
First Claim
1. A method of coordinating and stabilizing the delivery of wind generated power, comprising:
- using a wind farm having a plurality of windmill stations, wherein said wind farm comprises a predetermined number of immediate use stations dedicated to providing energy for immediate use, energy storage stations dedicated to storing energy for later use, and hybrid stations dedicated to providing energy for immediate use and/or storage;
forecasting or obtaining a forecast of wind speed conditions at the wind farm for an upcoming period of time;
using the forecasts to predict the wind speed conditions and the resulting wind power availability levels for the upcoming period of time;
preparing an energy delivery schedule based on the predictions for wind speed and wind power availability levels for the upcoming period, utilizing energy derived from both immediate use and energy storage windmill stations, and as necessary, the hybrid stations; and
using the delivery schedule to set a reduced number of constant power output periods during the upcoming period of time, during which time energy delivery levels can remain substantially constant, despite fluctuations and oscillations in wind speed and wind power availability levels.

Abstract
The invention relates to a method of coordinating and stabilizing the delivery of wind generated power, such as to a power grid, so as to avoid sudden surges and spikes, despite wind speed fluctuations and oscillations. The method preferably uses a plurality of windmill stations, including a number of immediate use stations, energy storage stations, and hybrid stations, wherein energy can be used directly by the power grid, and stored for later use when demand is high or wind availability is low. The method contemplates forming an energy delivery schedule, to coordinate the use of direct energy and energy from storage, based on daily wind speed forecasts, which help to predict the resulting wind power availability levels for the upcoming day. The schedule preferably sets a reduced number of constant power output periods during the day, during which time energy delivery levels remain substantially constant, despite fluctuations and oscillations in wind speed and wind power availability levels.
