Cyber-Physical Power System Testing Platform for Topology Identification in Power Distribution Grids
Challenge and objective
The transformation of passive electric power distribution grids (PDG) towards active ones relies heavily on digital and communication technologies to perform advanced functionalities such as optimal power flow or state estimation. The knowledge of the PDG topology is a fundamental requirement for enabling these functionalities.
Work performed
Analyze the topology identification algorithm developed in the literature under conditions of errors in the measurements and the pseudo-values inside a cyber-physical power platform.
Significant results
Topology Identification accuracy and robustness against error in the sensor and pseudo-measurements are tested in the CPPS platform. The results show that errors in the line current sensor with the communication layer are not as significant as the errors in the pseudo-measurements.
Impact for distribution system innovation
Helps the Distribution network operators to be able to identify topology of their MV and LV network by using different mix of measurements.
