NREL study confirms 30% more production opportunity on wind farm sites using wake steering
In case you missed it, on May 18, 2021 the National Renewable Energy Lab (Golden, CO) published its findings that wake steering decreases turbine spacing requirements. The white paper is here.
NREL's work shows that if you use control strategies designed to manage wake turbulence for planning and operating a wind farm, it will have 30% more opportunity for power (with the same "LCOE", levelized cost of energy) on the impacted sites.
If you have been following the science of wake management you know that this announcement is non-trivial. On its face it means that turbines on wind farms may need less space to operate. As a result, all wind farms should consider the impacts of wake and understand the state of technology that can manage and control wake turbulence as they plan new and repowered wind energy deployments, onshore and offshore, with site modifications.
Notably, in the NREL examples, maintaining power output with reduced spacing requires that the wind farm embrace wake steering control strategies. In doing so it can capture power gains and avoid operations & maintenance costs caused by wake turbulence. This process will necessarily entail using wake steering simulations to optimize site planning in advance of construction or repowering AND deploying wake steering control strategies on the farm once new turbines are live.
So, what does this reduction in turbine spacing mean?
From its most practical perspective the NREL study means less space will be required to deliver the same power. More importantly, a natural corollary here is that the same space should be able to produce more power.
Vayu is the leader in delivering control strategies that manage wake turbulence. Any consideration or conversation about wake and its impact/opportunity on every wind farm should begin with Vayu. Vayu offers site planning for every wind farm from thousands of analytical perspectives. Vayu's technology platform presents simulated results for control strategies using wake steering, classic greedy strategies or a combination.
Any analysis begins with advanced wake steering optimization and simulation capacity in comparison with classic strategies, opportunities and risk. Vayu provides simulations for both in its cloud based turbine control feedback loop and simulations.
Vayu’s cloud-based system is years ahead of the competition in this space. We rely on state of the art wake models and AI to simulate wind farm dynamics, making us well equipped to give a full analysis of the opportunity in both power and revenue terms from site planning to deployment (our technology also includes custom control algorithms, nacelle position calibration, loads & risk analysis and more).
