Embodiment Construction

[0031] as from figure 1 As can be seen in , the system 1 (in which the device according to the invention can be used for stabilizing the power supply) has at least one distribution network 2 in which one or more current generating devices of the electricity supplier 3 Feed current. The current generating device 3 is, for example, a power station, a wind power station or a photovoltaic system. Furthermore, servers 4 of various electricity suppliers or infrastructure suppliers can be connected to the distribution network 2 . exist figure 1 In the exemplary embodiment shown, two consumers 5 - 1 , 5 - 2 are connected to the distribution network 2 via a distribution station 6 . The substation 6 can be, for example, a substation. The two consumers 5 - 1 , 5 - 2 are, for example, private households with a plurality of power consumers or production facilities with power consumers for producing products.

[0032] In a possible embodiment, various customers 5 - 1 , 5 - 2 are suppli...

Abstract

Apparatus and method for stabilizing an electrical power import from a power distribution system (2) by means of at least one subscriber (5), which is connected to the power distribution system (2) via an electrical connection. An electrical power import anomaly when electrical power is imported by the respective subscriber (5) from the power distribution system (2) is identified using transmitted control messages, which are determined for the respective subscriber (5) or originate from the respective subscriber. Once an electrical power import anomaly has been identified, power consumption units (10, 11) or power generation units are driven correspondingly. The apparatus according to the invention effectively protects the power distribution system (2) from third-party intervention or implementation errors which can bring about an unstable system response.

Description

technical field [0001] The invention relates to a device and a method for stabilizing power supply of a distribution network. Background technique [0002] A large number of different consumers can be connected to a power distribution network, each of which operates a plurality of consumers. Such users can also be households, which have many different domestic appliances, such as washing machines, refrigerators or the like. In addition, such users may also include production plants, which use machines that require electrical current in the manufacture of products. Several power plants or current generators, in particular power plants, but also photovoltaic installations and wind power plants, can be connected to such a conventional power grid. Increasingly, current is also fed into the network via decentralized current generators, for example via photovoltaic installations installed on customer roofs. In order to save energy, more and more controls are carried out on the ...
