Embodiment Construction

[0024] figure 1 A first part of the grid 110 is shown, comprising the device 100 and the network component 120 .

[0025] Network component 120 may be any type of network component, such as a generator, consumer load, reactance, power storage, power transformer, circuit switch, or the like.

[0026] Grid 110 is divided into two hierarchical levels in this example, which are figure 1 are depicted as a first portion 110a and a second portion 110b. Many more hierarchical levels may also be used. In this example, network element 150 separates the two hierarchical levels. Network element 150 may be a solid state transformer. Preferably, the solid state transformer is suitable for continuous power transformation eg in the range of DC to 60 Hz on the primary side and DC to 60 Hz on the secondary side.

[0027] The network element may be any other type of network element, such as network element 120 or a voltage divider.

[0028] The first part 110a in this example is a transmis...

Abstract

The invention concerns a device (100) comprising a receiver (101) adapted to receive information about a first part (110a) of a power grid (110) at a first hierarchic level of the power grid (110) and information about a second part (110b) of the power grid (110) at a second hierarchic level of the power grid (110), a processor (102), adapted to determine a first set point for controlling the first part (110a) of the power grid (110) and a second set point for controlling the second part (110b) of the power grid (110) depending on the received information, and a sender (103) adapted to send information about the set points. The invention concerns a respective method as well.

Description

technical field [0001] The invention relates to a method and a device for controlling an electrical network. Background technique [0002] The grid is formed into a hierarchy comprising, for example, dedicated sub-networks for transmission and distribution networks. Individual subnetworks are designed to operate at predetermined voltage levels. Electricity transmission systems, for example, operate at 220 kV or 380 kV and 735 kV or 765 kV in Europe and North America, respectively. Distribution networks for example operate in the range of 1kV-60kV and 1kV-72.5kV in Europe and North America respectively [0003] Transmission and distribution lines use, for example, three-phase AC and sometimes single-phase AC. Direct current is also used for very long distances or for submarine cables. The voltage levels and frequency characteristics of the individual sub-grids are matched to optimally transmit or distribute power at a predetermined voltage or frequency in the grid. [00...
