Cyber-Physical Distribution Power System for Assessing Voltage Regulation with State Estimator and Topology Identification in the Loop

The continue evolution of complex power systems requires new tools and experimental setups to verify in a practical form the development of advance management systems. This work shows the different cyber-physical layers of power systems and multiple applications necessary to keep the voltage of a distribution grid inside the safe operating limits. Moreover, This paper demonstrates the integration of a voltage regulation (VR) method in an emulated distribution system operator’s (DSO) control centre (CC). The voltage regulator is based on control of photovoltaic generators production. Measurement data obtained in a real time simulator environment arrives to CC with the support of 5G communications. Hence, data can be stored in the DSO’s database. Finally, topology identification and state estimator are performed to feed information into the voltage regulation application. Hardware-in-the-loop validation has been developed to validate the VR approach.
