Method and system for hybrid wind power generation
First Claim
1. A method for operating a hybrid wind system comprising a wind farm having a plurality of wind turbines and one or more energy storage units to decrease a frequency of replacement of the one or more energy storage units, the method comprising:
- acquiring actual wind power data associated with one or more dispatch windows;
determining, by a processor, forecasted wind farm power estimates corresponding to the one or more dispatch windows using a plurality of forecast schemes;
computing, by the processor, difference values by comparing the forecasted wind farm power estimates to the actual wind power data;
identifying, by the processor, a wind power forecast scheme based at least in part on the computed difference values;
determining, by the processor, a damage equivalent quantity of the one or more energy storage units based at least in part on the forecasted wind farm power estimates for a dispatch window of the one or more dispatch windows determined based on the identified forecast scheme and the actual wind power data for the dispatch window of the one or more dispatch windows,wherein the damage equivalent quantity for a respective energy storage unit is given by equation;

Abstract
A method for optimizing a hybrid wind system including a wind farm having a plurality of wind turbines and one or more energy storage units, is presented. The method includes acquiring actual wind power data associated with one or more dispatch windows. The method includes determining forecasted wind farm power estimates corresponding to the dispatch windows using a plurality of forecast schemes. The method includes computing difference values by comparing the forecasted wind farm power estimates to the actual wind power data. The method includes identifying a wind power forecast scheme based at least in part on the computed difference values and balancing a penalty to the grid with life consumption of the energy storage units while regulating the wind turbines and the energy storage units based at least in part on a subsequent forecasted wind farm power estimate generated using the identified wind power forecast scheme.
