Wind Turbine Testing Using Nacelle LIDAR

This webinar will present an overview of nacelle-mounted LIDAR wind measurement technology as well as two research results from early experience applying the technology. It will also include a panel discussion including a consultant, a LIDAR equipment manufacturer, a developer, a turbine vendor, and a tax equity investor. A lively discussion is anticipated including the motivations to utilize nacelle-mounted LIDAR, advantages and limitations of the technology, risks of using the technology weighed against the risks of foregoing power performance testing altogether, anticipated industry acceptance of this new technology, practical considerations for deployment of the technology, and next steps in advancing the state-of-the-art in nacelle-mounted LIDAR technology.

Validating time-domain energy assessments: wake modelling considerations and recommendations

Power time series simulations are important for estimation of the revenue produced by wind farms to ensure co-varying patterns in energy production and market energy prices are captured. This study characterizes patterns in power time series modelling errors utilizing ‘Eddy Viscosity’, ‘Modified Park’ wake models, and other DNV’s research models to test and recommend possible improvements to the models. We present results of steady-state time series simulations for multiple wind farms, comparing modeled and actual power outputs based on turbine SCADA data.

Lifetime Extension and Partial Repowering: Availability Forecasting of Aging Assets

This panel will explore how variables may change in a partial repowering or life extension scenario, how they may impact long-term energy forecasts, and what is on the horizon for further refinement of the uncertainties.

Methodology Refinements in Solar Energy Assessments

Solar projects of all sizes have generally been producing less than their long-term energy forecasts. There are numerous studies* demonstrating the project underperformance is an industry-wide problem, including one that shows nearly half of project years are not hitting their 1-year P90 and P50 gaps of >7%. Unfortunately, DNV’s own solar energy assessments are not immune to this problem. In 2019, DNV published a white paper illustrating a 3.1% shortfall in our own energy assessments. In this presentation, DNV will focus on three particular areas that DNV will address in this shortfall: 1) terrain losses, 2) sub-hourly clipping losses and 3) wind stow losses. We will cover briefly how these losses occur and the methodology that is used to calculate these losses.

Are we ready for LiDAR only measurement campaigns?

Accurate wind resource and energy production assessments are the cornerstone of wind farm development. Both are important to get right from the start of any project to optimize the site and safeguard investment. For decades, conventional meteorological masts equipped with mechanical cup anemometry have been the stalwart ‘go-to’ for wind measurements. However, the last decade has seen a rapid rise in the development and application of LiDAR based remote sensing. These devices are typically quicker and easier to deploy, avoiding the drawn-out planning consent process to construct a tall meteorological mast. However, historically anemometer-based measurements have been the basis of industry models. Can we expect LiDAR-based wind measurements to provide comparable results in an energy assessment? Are we ready for measurement campaigns based solely on LiDAR measurements?

ERA5: Rad Or Just a Fad?

It is vital that the reference datasets used in analyses not only correlate well but are temporally consistent so that the most accurate long-term wind speeds and P50 can be estimated. DNV presents results assessing the data consistency of ERA5 compared to MERRA-2 across North America and addresses whether or not ERA5 is a reliable data source for use in wind resource assessments.
