Topology Identification in Distribution Networks based on Phasor Measurement Units

This paper proposes a method for topology identification based on phasor measurement units installed in a limited number of nodes. This method identifies the network topology through the comparison of multiple state estimates performed by considering the possible network topologies.

The distribution network is becoming more complex due to the integration of distributed energy resources which causes frequent reconfigurations of the network. In this context, knowledge of the grid topology is fundamental for the control and management of the entire system. Incorrect topology information leads to problems regarding the safe and reliable operation of the network. The minimum difference between real system states and state estimates indicates the actual network topology. To validate the proposed method, simulations were carried out considering a low voltage distribution network with measurements simulated by PMU. The simulation results highlight the good performance of this method, with a correct identification rate of over 77% for all possible network configurations considering loads and generators varying over time.
