Abstract

The invention provides an intelligent active power management system for renewable variable power generation. A method and system for intelligently directing output boost capabilities of wind turbine generators (310, 312, 314) operating together in a wind plant (300) has been provided. Selected ones of the wind turbine generators have their own individual boost modes of operation that can provide a limited time increase in power output. This boost capability of the selected individual generators (116) is conveyed to the wind plant control (328) upon request and is used to direct individual boot operations of the generators. In some embodiments, weather forecast information (340) including wind forecast information is used to calculate the generators present and future forecasted boost capabilities.

Description

technical field [0001] The present invention relates generally to the field of wind turbine generators, and more particularly to methods and systems that allow for intelligent and temporary increases in the power output of wind turbine generators for stabilizing power during transient conditions. Background technique [0002] Wind turbine generators are considered an environmentally friendly and relatively inexpensive alternative energy source for generating electricity from wind energy. Wind turbine generators generally include a wind rotor with turbine blades that convert wind energy into rotational motion of a drive shaft, which is then used to drive a rotor of a generator to generate electricity. Modern wind power systems typically take the form of wind farms having a plurality of such wind turbine generators operable to supply power to a transmission system that provides power to utility systems. [0003] These wind turbine generators and wind farms are typically desig...
