NaturEner – Natural Energy for a Sustainable Future – NaturEner USA Participates in Project to Improve Wind Power Forecasting

Posted on

NaturEner USA has partnered with WINData LLC and OSIsoft, LLC to improve forecasting of ramp events for the Glacier Wind farms in Montana. The effort is a DOE funded research project to improve forecasts of ramps events for wind farms, titled “Use of real-time off-site observations as a methodology for increasing forecast skill in prediction of large wind power ramps one or more hours ahead of their impact on a wind plant”.

NaturEner is uniquely interested in improving wind forecasts because the Glacier Wind farm operates as a wind only balancing authority, and improved forecasts are the most cost effective way to improve reliability and reduce integration costs. Toward this end, NaturEner has specified performance metrics to quantify the ability of the forecast to predict ramp events. WINData and OSIsoft have created a grid of next generation offsite meteorological sensors in the region around the wind farm, and have contracted with Garrad Hassan to help develop WINDataNOW Technology, a novel forecasting approach to incorporate these measurements. The OSIsoft PI software is being used to collect and transfer the data to Garrad Hassan, and to display the forecasts and measurements to NaturEner’s real time scheduling desk. WINData and Garrad Hassan are presenting promising preliminary results at the UWIG forecasting workshop. NaturEner is now receiving the forecasts and will evaluate their performance operationally.

WINData’s “WINDataNOW! Technology” was developed under research support from John Deere Renewables, NaturEner and the US Department of Energy. WINDataNOW! is a 4G high-fidelity real-time met data technology leveraging OSIsoft PI for use by wind energy integrators, forecasters, developers and plant and system operators.

WINDataNOW’s core technology takes advantage of many industry standard pieces of equipment and combines them to deliver real-time meteorological data to users. Various meteorological tower configurations and instrument combinations are possible and vary by individual site characteristic and customer specifications. WINDataNOW can even add non- standard sensors as required to further characterize the wind flows of a prospective site.

While today’s site assessment technology relies on 10 minute average wind speed readings, the WINDataNOW technology records a much higher fidelity data set (usually second-by-second data). Legacy systems paint an even more incomplete picture of a site’s potential operations once that 10 minute average data is rolled into hourly, daily or monthly averages.

WINDataNOW’s technology gives users the flexibility to use their high fidelity data in any manner necessary. They can easily assess a site’s behavior and dynamics during seasonal, diurnal, or synoptic variations over long periods of time without sacrificing their source data quality.

In order to deliver higher fidelity data to customers, WINDataNOW uses quality instrumentation that can deliver a more exact representation of the wind speed information to the WINDataNOW data acquisition system. The system is able to communicate wirelessly to a central server and deliver near-real time data to customers.

Because WINDataNOW uses OSIsoft’s industry leading PI System as its data repository, most utility and operating companies can use their live met data at its full fidelity just like any other data source that feeds their on-site PI System. This enables wind experts to interact with their data in familiar tools such as Excel, or PI ProcessBook. Met data can also feed directly into forecasting provider models and can be used to support rapid refresh.
