wind ramp events
Customers can use their data for any number of applications that pertain to site selection, farm design, and forecasting or day to day operations of a farm.
Example applications include:
Better design validation before site construction commences
Better, more predictable wind site operation
Gap analysis between performance potential vs. actual performance for use in service level agreement compliance, accounting, and manufacturer warranty claims
Customized analytics to help with reporting to power offtakers, transmission system operators, regulatory agencies and joint venture or partner companies
Upstream weather observation-based “feed-forward” scheduling for site operation planning
Combining upstream weather observations with complex forecasting models to increase confidence in day ahead and intra- hour power predictions
Customers can perform routine calculations on a real-time basis as data arrives to the system rather than in batches. These calculations can also be augmented over time so that some users can start simply and expanding their analyses as they discover more applications of interest.
WINDataNOW is leveraging operating wind plants and technology partners to better describe the possibilities for using high fidelity, real-time meteorological data for wind farm site selection, design and operation.
WINData professional services comprise meteorological (“met”) system array design, tower specification, project installation and data integration to support end user wind integration requirements and forecasting data services. WINData has partnered with OSIsoft to develop “WINDataNOW!”, an advanced meteorological measurement system built on PI, for use as framework for tools used by wind energy system integrators, forecasters and plant operators.
OSIsoft delivers the utility industry standard COTS PI System, which provides secure access across various elements of utility infrastructure, from fuel source, generation, transmission, distribution, AMI, and below the meter data/information services, comprising a complete end-to-end view of the smart grid and utility “enterprise”.
In addition to the owner/operators, the PI system is used extensively by the various Transmission System Operators as the real-time basis for the EMS networks, integrating the various generation sources into the grid. The WINDataNOW! solution provides real-time PI to PI transfer of processed information directly into the scheduling coordinator and system operator environments.
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.
WINData installs on-site permanent met towers and off site sensor arrays for use in wind forecasting, plant operations and energy scheduling. Combining real met data from remote locations around the wind plant allows operators to get a critical preview of the weather that is heading toward the farm. This allows them to participate more effectively in their respective markets and also reduce the impact of short term forecast error and unexpected ramp event on the production of power at the plant.
WINData’s real-time data is collected and stored alongside the plant’s SCADA data in an OSIsoft PI server and can be queried and used in more sophisticated RUC forecasting models, thus insuring greater accuracy and advanced warning about pending weather patterns.
WINData’s expertise and high fidelity data, have been employed since 2007 to help wind plant operations become more of an exact science that can be optimized for each plant’s site characteristics. Proper on and off-site sensor array design, combines with state of the art forecast models to help wind assets perform progressively closer to their peak potential and gives the best return on investment possible.
