Abstract (en)

[origin: WO2021110368A1] The invention relates to a method for ascertaining a load flow map within an AC-voltage power supply grid (1), wherein a multiplicity of grid subscribers (10) is arranged at a respective grid connection point (11) in the power supply grid (1). The method comprises the following steps: - the multiplicity of grid subscribers (10) ascertaining a respective value reflecting an individual phase angle (Φ) of the AC voltage of the power supply grid (1) at the respective grid connection point (11); - transmitting the respective value in the form of data from the multiplicity of grid subscribers (10) to a superordinate data receiver; - evaluating the data and creating a load flow map on the basis of the values reflecting the individual phase angles (Φ). The invention furthermore relates to an arrangement for performing the method.
