Abstract

A technique for data interchange between a wind plant and external wind forecasting agents is disclosed. This technique proposes various standards for data representation (such as Extensible Markup Language (XML) based format) and/or network protocols (such as Hypertext Transfer Protocol (HTTP)) for transferring the forecast data between the wind plant and the forecasting agents. This technique allows the forecasting agents to access the operational data (e.g. measured wind speed, power) from the wind plant and then transmit the forecasted data (e.g. forecasted wind speed, forecasted power requirements) back to the wind plant for operation and power management.

METHOD AND SYSTEM FOR DATA INTERCHANGE AT WIND PLANTS

BRIEF ABSTRACT

    A technique for data interchange between a wind plant and external wind forecasting agents is disclosed. This technique proposes various standards for data representation (such as Extensible Markup Language (XML) based format) and/or network protocols (such as Hypertext Transfer Protocol (HTTP)) for transferring the forecast data between the wind plant and the forecasting agents. This technique allows the forecasting agents to access the operational data (e.g. measured wind speed, power) from the wind plant and then transmit the forecasted data (e.g. forecasted wind speed, forecasted power requirements) back to the wind plant for operation and power management.

DETAILED DESCRIPTION

    Wind power is increasingly gaining importance in the area of renewable sources of energy generation. The wind power is generated through a wind turbine that includes a wind rotor having turbine blades that transform wind

energy into rotational motion of a drive shaft, which in turn is utilized to drive a rotor of an electrical generator to produce electrical power. In recent times, wind turbine technology has been applied to large-scale power generation applications. Modern wind power generation systems typically take the form of a wind turbine farm (or wind-farm) having multiples of such wind turbines that are operable to supply power to a transmission system providing power to a utility system.

    In a wind plant system, production forecasting is mostly required to decrease the operational costs, and to efficiently aid the wind plant grid integration. The forecasting may be obtained from various external forecasting agents. The forecasting agents require wind plant operational data (e.g. measured wind speed, power, etc.) in order to compute the forecasts. In conventional forecasting techniques, forecast data is transferred to the wind plant system by means of periodic file transfers, such as using File Transfer Protocols (FTP) or even through emails. The files are usually formatted as per the Comma Separated Values (CSV) format.

    Further in conventional forecasting techniques, the systems involved in generating and transmitting such forecasts are very complex, expensive and involve human intervention. Therefore it is desirable to standardize the protocols for data conversion and transfer for such data forecasting between the wind plant and the forecasting agents. Such standardization can save time and development efforts for all involved parties in establishing an efficient...
