Definitions

  • the invention relates to a method for regulating the stability of an electrical supply network.
  • the method is preferably applicable to electrical supply networks to which in addition to conventional energy-generating plants, such as coal power plants, gas power plants or nuclear ⁇ energy plants, and energy generation plants are connected, which feed time varying electrical energy into the supply network ⁇ supply.
  • energy-generating plants such as coal power plants, gas power plants or nuclear ⁇ energy plants, and energy generation plants are connected, which feed time varying electrical energy into the supply network ⁇ supply.
  • These systems include, for example, wind turbines or solar energy systems.
  • a first device which is designed to exchange electrical energy with the supply network, determines via its geographical location a part of the supply network to which the first device for the energy connection is assigned.
  • the first device determines parameters for an intended energy exchange.
  • At least one second device associated with the same part of the supply network for energy exchange determines parameters for an intended energy exchange.
  • the first device takes the energy exchange, taking into account the parameters of the first and second device in such a way that the electrical stability of the part of the supply network is ensured.
  • the mode of operation of the exchange of parameters can be carried out in a similar way to the peer-to-peer communication known per se.
  • car-to-car communication may also be comparable to car-to-car communication, as used for example for networked warning systems between motor vehicles (cars).
  • Parameter sources for local optimization of a part of a network can be, for example, end consumers, network nodes and / or external data sources.
  • e-car electric motor vehicles
  • e-car determine the first parameter parameters
  • traffic control systems offer as external data sources, for example, traffic control systems. These allow the flow of traffic to estimate how many "e-cars" are traveling that might need electrical energy.
  • Weather forecasts also allow location-related statements about an expected traffic flow of "e-cars" in the form of an external database. For example, on public holidays or working days, the energy requirements of "e-cars” will change depending on the weather.
  • a customer forecasting system that estimates an expected energy requirement can also be used as an external database. Due to the decentralized approach no central control ⁇ unit is necessary, so that the network has an increased Robust ⁇ uniform and fast control dynamics.
  • the inventive process permits due to the dezentra ⁇ len approach also gradually introduce the method in existing networks ⁇ supply, so gradually equip these disadvantages. The invention will be explained with reference to a figure FIG 1 he ⁇ .
  • a first device Gl which is designed to exchange electrical energy Pel with a supply network VNW, determines its geographical position
  • An assignment of the first device is performed Gl to a part of the supply network TVNW VNW by means of the geographic location in a two-POS ⁇ th step.
  • the position determination can be done for example via GPS. It can also be effected via signals which are exchanged with a designated point of the supply network VNW via an electrical supply connection or connection cable.
  • the connecting cable is preferably used, which is provided for an intended energy exchange between the first device Gl and the supply network VNW.
  • the first device Gl determined parameter for a PARI beab ⁇ schreibten exchange of energy and transmits it to a designated Administrator VERW.
  • the Administrator VERW may be formed as a central unit of the GE ⁇ entire supply network VNW. Or it is provided as one of several decentralized units at an associated part of the utility network VNW. At least one second unit G2 which is the same part of the supply network TVNW zugeord ⁇ net for an exchange of energy, also determined in a further step, para- meter PAR2 for an intended energy exchange.
  • Steps are taken, which are used by the first device Gl to determine the parameter PARI.
  • the first device Gl assumes in a further step before the Ener ⁇ gienic taking into account the parameters of the first device PARI Gl and the parameter PAR2 the second unit G2 such that the electrical stability of the part of the supply network TVNW is ensured.
  • the evaluation of the electrical stability is ⁇ example as part of the Central Administration or by the decentralized management structure in the supply network VNW.
  • the first device could take over this functionality as a "requesting" device, provided that the required parameters for assessing the stability of the supply network part are transmitted to it.
  • Is determined by the Administrator or the part of the ERS th device is that the associated part of the Ver ⁇ sorgungsnetztechniks has sufficient electrical resources (eg Leis ⁇ tung) is available, then the first device performs the attached ⁇ desired energy exchange.
  • an e-car would be the first device in this case to recharge its deflated batteries.
  • an e-car will carry the desired energy from ⁇ exchange as the first device and its depleted batteries aufla- back to.
  • the e-car will not be the first device to carry out the desired energy exchange immediately and, if necessary, recharge its deflated batteries later.
