Abstract (en)

[origin: WO2020064331A1] The invention relates to a method for determining the grid state of a low-voltage grid of an energy supply system (2), comprising a gateway (3) and a monitoring device (4). The energy supply system (2) has grid lines (311-319) with respective smart meters (101-109), which form a grid topology of the low-voltage grid (1). Communication paths are formed between the smart meters (101-109) and the gateway (3) by applying powerline communication technology to the grid lines (311-319), said paths together forming a communication grid with a communication topology, and communication properties, comprising routing information (RI) which describes the communication path between the gateway (3) and the respective smart meter (101-109), are ascertained as at least one communication parameter by means of the respective smart meter (101-109), the communication topology being determined from said communication parameter. The grid state of the low-voltage grid (1) is determined from a comparison of the grid topology with the communication topology by means of the monitoring device (4), wherein a change in the structure of the communication topology with respect to the structure of the grid topology is analyzed, and in the event of a change in the structure of the communication topology, a comparison is carried out with weather data and is taken into consideration when determining the grid state.
