"Decentralized measurements of the grid state",
Presentation at 7th International Energy and Sustainability Conference
2018), Cologne, 17.-18. May 2018
At a certain level of renewable energy penetration this also requires
a decentralized grid control. As a possible option, grid connected devices
could be able to detect the state of the power grid by measuring physical
parameters at their point of connection. They would then be able to
react on such information with a suitable reaction. No data connection
would be necessary.
The grid voltage gives information about the grid state at this point
and the grid frequency informs about the state of the total grid. However,
neither information about the grid state in the region, nor about the
neighbourhood can be obtained. This contribution shows options for further
measurements at the point of connection. As one option, the measurement
of the grid impedance can give an indication about the load state of
the grid branch in the vicinity of the connected device. First approaches
for related measurements and their results are discussed in this presentation.
