Abstract

The method involves detecting information about the weather from multiple systems (6,8,10) distributed on the earth, which are designed for converting energy. The information is transferred to a central device (4). The information about the weather from a system is indirectly detected by determining a value of an operation parameter of the system. An operation parameter is dependent on weather and the information about the weather is derived from an operating parameter. An independent claim is also included for an arrangement for providing forecast.

Description

The invention relates to a method and an arrangement for providing a weather forecast.

State of the art

Weather forecasts are usually created by converting series of measurements into mathematical models. Since the equations underlying the models are often non-linear, even small changes in the output variables detected in the measurements can lead to significant changes in a target variable to be provided, which can be manifested by the so-called butterfly effect. Therefore, the quality of weather forecasts is usually based on the depth of detail of the measurements. So far, measurements have been taken using weather satellites, remote sensing systems and stationary ground observation stations, also referred to as climate gardens. Due to their costs, such climate gardens are available only to a very limited extent, so that only about 10,500 of them are available worldwide.

The publication DE 10 2008 034 924 A1 describes a method for forecasting a large-scale weather situation, which allows the most accurate local weather forecasts, which are moreover valid for several days. In this method, weather physical variables are determined with local sensors and transmitted to a computing unit. The method can be realized without great technical effort, so that there is the possibility to use small and inexpensive weather stations.

Disclosure of the invention

Against this background, a method and an arrangement with the features of the independent claims are presented. Further embodiments of the invention will become apparent from the dependent claims and the description.

The inventive method exploits information about the current weather situation, which are provided by systems that are designed to convert energy and distributed on the ground decentralized. Thus, weather forecasts can be significantly improved. At the same time, a large number of systems distributed over the earth in a spatially distributed system for the conversion of energy supply information about the weather, which is transmitted to and evaluated by a central facility.

With the invention, an improvement of weather forecasts can usually be made possible by more detailed output data provided by the plants. For this purpose, in one possible embodiment of the method according to the invention, information from earth and / or stationary installations for regenerative energy production, for example photovoltaic and / or wind power plants, is collected and thus bundled and centrally evaluated.

A collection of data is decentralized by already existing, typically installed on Earth and / or mobile facilities for the conversion of energy, which are distributed decentralized on Earth. Depending on the nature of the equipment, information about the weather, i. H. climatic and / or meteorological parameters about the current weather conditions, eg. As solar radiation, wind direction, wind speed, wind intensity, temperature, air pressure, humidity, precipitation and other climatic and / or meteorological parameters, directly via at least one arranged in a system sensor and / or determined indirectly. For this purpose provided sensors are u. a. Thermometers, barometers, windsocks and hygrometers.

In the indirect determination of climatic and / or meteorological parameters is taken into account how much electrical energy and thus electricity is generated by a plant for regenerative energy production during a short time interval, for example. From a value for the generated energy and / or from a power of the plant for regenerative energy production, an information to be determined about the weather is derived by calculation. Thus, for example, from the power of the current, a solar radiation or a wind speed in the time interval can be determined indirectly.

The measured and available weather information may be transmitted to the central facility with supplementary information about the location of the measuring equipment as well as information about the measured time interval and / or a time of measurement via a suitable infrastructure for transmitting data; the example. Can be configured as a mainframe of a weather service. Wired and / or wireless transmission media can be used as infrastructure for the transmission of data. In this case, a wireless transmission of data with electromagnetic waves can take place. In the central facility, the information from the facilities is combined and taken into account in models for weather forecasting. However, it is also possible to provide weather forecasts solely on the basis of the information provided by the plants as part of the process.

In addition to the use of information from the above-mentioned fixed installations for Regenerative energy generation as sources of information, it is also possible to merge information from other information sources distributed on the earth decentralized. For example, motor vehicles can provide further information about the weather via a suitable infrastructure. Such motor vehicles can be ground-based motor vehicles or land vehicles and / or watercraft, such as, for example, passenger cars, trucks, trains and / or ships traveling on earth.

For example, with a thermometer as the sensor, an outside or ground temperature can be measured and / or a precipitation amount can be determined with a rain sensor. The information provided by motor vehicles may become unreliable. a. transmitted via a vehicle-to-car and / or vehicle-to-infrastructure data transmission to the central facility. The localization of motor vehicles is usually via a positioning system, such as the satellite-based, global positioning system GPS. With the trained as land vehicles vehicles can be provided for different places on the earth information about the weather.

In an implementation of the invention is a summary and / or bundling a very large number of plants that are distributed decentralized on Earth, and the climatic and / or meteorological parameters directly and / or indirectly capture and thus information about the weather of different places deploy on the earth, possible. This allows weather forecasts to be significantly improved and made plausible. Although there is a high density of climatic gardens in Germany by international comparison, forecasts for the weather are based on measurements of less than one hundred stations near the ground. The invention allows many already existing attachments to be used as additional measurement stations.

The arrangement according to the invention is designed to carry out all the steps of the presented method. In this case, individual steps of this method can also be carried out by individual components of the arrangement. Furthermore, functions of the arrangement or functions of individual components of the arrangement can be implemented as steps of the method. In addition, it is possible for steps of the method to be realized as functions of at least one component of the arrangement or of the entire arrangement.

Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings.

It is understood that the features mentioned above and those yet to be explained below can be used not only in the respectively specified combination but also in other combinations or alone, without departing from the scope of the present invention.
