The method for determining mutual voltage sensitivity coefficients between a plurality of measuring nodes of an electric power network does not rely on knowledge of the network parameters (for example: series conductance and susceptance of the branches, shunt conductance and susceptance of the nodes, etc.). The method uses a monitoring infrastructure including metering units at each one of the measuring nodes, and includes a step of measuring at the same time, at each one of the measuring nodes, repeatedly over a time window, sets of data including values of the current, the voltage, and the phase difference, a step of computing active power, reactive power and values from each set of measured data, and a step of performing multiple parametric regression analysis of the variations of the voltage at each one of the measuring nodes. 11717. A method for determining mutual voltage sensitivity coefficients between a plurality of measuring nodes (M , . . . , M) of an electric power network () , the electric power network being provided with a monitoring infrastructure comprising metering units at each one of said measuring nodes , for measuring a voltage , a current and a phase difference between the voltage and the current , locally , the monitoring infrastructure comprising a processing unit () connected to a communication network , the metering units being connected to the communication network so as to allow for data transmission to and from the processing unit; the method comprising the steps of:{'b': 1', '7, 'sub': 1', 'm, 'I. measure at the same time, at each one of said measuring nodes (M, . . . , M), repeatedly over a time window (τ), sets of data comprising values of the current (Ĩ(t)), the voltage ({tilde over (V)}(t), and the phase difference (φ(t)), timestamp (t ϵ{t, . . . , t}) the sets of measured data, and compute a timestamped active power value ({tilde over (P)}(t)) and a timestamped reactive power value ({tilde over (Q)}(t)) from each set of measured ...
