Methods and systems for optimizing farm-level metrics in a wind farm

摘要

A method for optimizing one or more farm-level metrics in a wind farm is presented. The method includes identifying an optimization objective and one or more decision variables for optimization. Furthermore, the method includes optimizing the optimization objective based on wake-affected wind conditions, power capture values, or damage equivalent load values, to calculate optimum decision variable values for each wind turbine. The method also includes transmitting the optimum decision variable values to the respective wind turbines. In addition, the method includes applying the optimum decision variable values to the respective wind turbines to achieve the optimization objective. Systems and non-transitory computer readable medium configured to perform the method for optimizing one or more farm-level metrics in a wind farm are also presented.

1. A method comprising:
acquiring prevailing wind information for a wind farm from wind sensors; modeling wake-affected wind conditions based at least in part on the acquired prevailing wind information; calculating power capture values and damage equivalent load values for at least some of a plurality of wind turbines on the wind farm; using the power capture values and the damage equivalent load values for determining an optimization objective of the wind farm and one or more decision variables for optimization, wherein the optimization objective comprises either maximizing farm-level power capture or minimizing farm-level fatigue loads, and wherein the one or more decision variables correspond to the determined optimization objective; optimizing the optimization objective based on the wake-affected wind conditions, the power capture values, and the damage equivalent load values to calculate optimum decision variable values of the wind farm; transmitting the optimum decision variable values to the respective wind turbines; and using the optimum decision variable values at the respective wind turbines to achieve the optimization objective.
