Instead of online dedicated lines, others can Find data connections.

background

Electricity from renewable energies is not considered beforehand sayable, so strictly speaking only the avoided fuel costs used as a cost saving compared to conventional power plants can be.

If a share of renewable energies of 30% is exceeded Power supply in a power grid are technical solutions for Stabilize the power grids and maintain a high level Power quality required.  

So far, the territorial sovereignty and the performance of the existing energy producers that after an expected load on power plants come to or connected to a network in blocks were disconnected. Smaller energy producers just their performance just off into this network. Fluctuations are caused by an oversupply compensated for the energy of the large power plants. This results in a very rudimentary load management, which is only in one time-dependent switching on or off or in one instructions given by telephone to a power plant operator or switch off.

steps

• 1. Establishment of an Umweltkontor business channels on which closed user groups / platforms extended infinitely modular can be.
• 2. Setting up a b2c (business to consumer) platform on which customers or limited partners or other users can view currently selected data from the respective wind turbines.
  The prerequisite for this is software that is based on the controls of the Umweltkontor wind turbines, which can tap and process data. It may be necessary to install computers in the individual plants or change the communication configuration in the individual wind farms.
  A prerequisite is also the establishment of a dedicated line via the Internet (voice-over communication). Of course, other line systems can also be used.
• 3. Expansion of the system according to 2. to an automated monitoring and operational management software for wind turbines
  Automated, up-to-date data acquisition in every wind turbine, transmission of data online to the internet platform, automated data storage and evaluation, automated forwarding of messages to operators and manufacturers / service in the event of operational disruptions and in the event of maintenance and service interval appointments. At the operator's request, these notifications are made available by telephone, fax, SMS and / or mail. Answers of the manufacturer / service, esp. Appointments, deadlines, causes of faults, etc. are also forwarded immediately.
  Extension of the application as a service for other operators of wind turbines.
• 4. Expansion of the system according to 3. to an automated monitoring and operational management software gradually for everyone else Renewable energies.
• 5. Expansion of the system to a European control center for power plants for the use of renewable energies, for a European one Load management of renewable energies and for central trading with  Electricity from renewable energies on the European electricity exchanges in the liberalized market.

The first step would be the integration into a power grid of a regional energy supplier. Then that should System first expanded in Germany, then across Europe. The The system supports the load management of the Network operator, the Umweltkontor control center serves as an interface to the control centers of conventional energy suppliers.

Challenges

Integration of various control software of the different Wind turbines.

Integration of controls of hydropower plants, Photovoltaic plants, biomass CHP plants, biogas plants, Solar thermal and geothermal power plants.

Strong fluctuations in the provision of energy from renewables Energies (storm gusts for large wind farms, especially offshore, change between strong sunlight and storm clouds with solar power works) in the short-term range.  

aims

Integration (networking) of all operators (independent power Producer) of power generation plants using renewables Energies in the region, in Germany, in Europe (in the world).

(Power) control of all power plants, the wind energy, the Solar energy that uses biomass (the renewable energies) in one Region, in Germany, in Europe for a regional, Germany-wide, Europe - wide load management and for central control and Regulation, especially in the short-term area.

Bundling the producers of electricity from renewable energies Achieving maximum prices on the European power exchanges in one liberalized market.

In the long run this software is based on the software of the system control set up to make the standard in the individual industry segments, so that the control manufacturers have to adapt to this control. The pressure must come from the operators, whose benefits in the Saving telephone costs for surveillance, transparency all operating data of all wind turbines, the Cost minimization with the operational management and later with the Achieve maximum prices on the electricity exchanges.

From the specification of the current state of an energy supplier Information about the expected productivity, failure or Maintenance times can be gained. By determining the  achievable performance, for example due to solar radiation, Wind fluctuations or other external conditions can fluctuate, a current adjustment can be made.

By forecasting the expected energy, can - even if this Forecast should be relatively inaccurate, time saved to anticipate fluctuations in performance due to addition additional energy producers, through the purchase of energy or through a Switching on energy storage better, especially with a little more Time to be responded.

By an output unit for outputting an information data record with information about the status of at least one energy producer and / or the electricity network, the means for checking the authorization one of the output unit readers to receive this information includes, anyone within the scope of his authorization accordingly ask. For example, customers, individual owners Be energy producers, electricity network operators etc. For example Owner or co-owner of individual energy producers about the Inform the current state of your system and information about the Power generation, maintenance and downtime or others Receive information. This can go so far that pictures of the System or noises of the running system are transmitted.  

If this output unit is publicly accessible, the information can relatively simple and inexpensive by each Information seekers are asked.

It goes without saying that instead of wind turbines, any other type of Power generation plants can be used.

The invention also relates to a method for Power distribution, which is at least two decentralized Has energy feed points in a power grid, with a value for the power currently fed in at an energy feed-in point and compared with a target output and, depending on the result, the feed-in is adjusted accordingly at the other energy supply points. The Accordingly, the invention also relates to a device for Energy distribution, with which means to record the current fed at least one energy feed point into a power grid Performance, means for comparing the recorded performance data with a Target performance and means of adapting to the Power feed-in power according to the Comparative results are provided. Instead of the adjustment means can also provide means to request a corresponding Power change provided at at least one energy feed point his.

In this respect, the invention relates to a method and an apparatus for Energy distribution, which is independent of individual energy producers  load management guaranteed. In particular, this can also a network operator, in whose network energy from various locations will be made available.

Consumer data can also be recorded. This can be done through a consumer interface. Such On the one hand, the interface can be connected to another power grid, the power grid of a consumer, or lead to a final customer. Such However, consumer data can also be stored at certain nodes several consumers are recorded at the same time if one No detailed statement about the consumption of individual consumers is imperative.

The data can be transmitted in any conceivable way. In particular, there are public networks such as that Internet, on. In addition, the data can also be singular Data lines that are provided by ISDN, for example, be transmitted. In addition, it is also conceivable that the Power lines themselves are used. The latter has the advantage of one special connection between the database and data management and the individual data collection points is not necessary.

Means are preferably provided by means of which a Data acquisition station, be it on the feed side or be it on the consumer side, automatically integrated into the corresponding network. This can be ensured, for example, by using  Providing the network connection, this can be done with a Data acquisition device connected to the rest of the network Components communicates by simply connecting to it Power grid happen, an automatic link with this Network. For this purpose, for example, a corresponding one Registration routine expire.
