METHOD AND ARRANGEMENT FOR ASCERTAINING A LOAD FLOW MAP WITHIN AN AC-VOLTAGE POWER SUPPLY GRID

A method for ascertaining a load flow map within an AC-voltage power supply grid, wherein a plurality of grid subscribers are each arranged at a respective grid connection point in the power supply grid, includes ascertaining, by each of the plurality of grid subscribers, a respective value reflecting an individual phase angle (ϕ) of the AC voltage of the power supply grid at the respective grid connection point of each of the plurality of grid subscribers. The method also includes transmitting the respective values in the form of data from the respective plurality of grid subscribers to a superordinate data receiver; and evaluating the data and generating a load flow map based on the values reflecting the individual phase angles (ϕ).
