ABSTRACT
Dynamically limiting a wind plant for up-regulation capacity is rarely cost competitive with the market price for up-regulation; we estimate that a dynamically limited wind plant is competitive with market-procured up-regulation less than 1" of the time. A dynamic simulation better represents real turbines that cannot respond instantly to rapid changes in wind speed and cannot be dynamically limited below their minimum power limits. In our simulations, we do not allow the wind plant controller to command any wind turbine to dynamically limit below its lower operating limit (LOL) of 20" of its rated power, but a turbine's power output may go below that limit when the wind speed is low. The wind plant is simulated with 60 days of wind speed data sampled randomly from a given year at a given location. The reserve of power created when a generator operates below its maximum is known as capacity.
