Description

Doppler Lidar-based Feed-Forward Control - Feasibility Study Doppler Lidar-based Feed-Forward Control - Feasibility Study Although the scientific literature demonstrates that 3D scanning Doppler lidars can provide spatially resolved measurements over entire wind farm domains, obtaining wind vectors, characterizing errors, and coordinating multi-sensor configurations requires both new expertise and considerable computing power. The purpose of this proposal is to lay a foundation for Doppler lidar-based Feed-Forward (FF) control of wind farms by exploring fundamental feasibility questions. A key outcome for the wind energy community (and a necessary precondition for subsequent commercial investment) would be a broadly accepted theoretical basis (in peer-reviewed journals) for FF control using scanning Doppler lidar. This is a central goal of the proposed project. The approach is unique and novel proposing to build FF control on spatially distributed, numerically intensive remote sensing measurements, rather than on short-range, single profile instruments. How do the spatial and temporal details of scanning modes define (or limit) the type of flow features which can be sampled, and which could therefore provide a basis for enhanced energy capture or fatigue mitigation? What are the tradeoffs between more spatial coverage versus higher resolution? What aspects of yaw and pitch control can be feasibly addressed with 3D scanning Coherent Doppler Lidar (CDLs)?
