Cyber-Physical Co-simulation Framework between Typhon HIL and OpenDSS for Real-Time Applications

Abstract

Cyber infrastructures have been extensively used for power system monitoring, control, and operation because of the development of new information and communications technology (ICT) in power systems. Deployment of cyber-physical co-simulation in the case of a realistic distribution network is still a big challenge. Hence, to solve the problem of modelling complex distribution networks, a cyberphysical co-simulation framework is proposed in this chapter. The proposed framework consists of a cybernetic layer, a physical layer, and a co-simulation framework between OpenDSS and Typhoon HIL. The cyber layer consists of software and tools to model the distribution system and communicate with the physical layer. The physical layer is the Typhoon HIL real-time simulator consisting of virtual or real controllable devices. A realistic framework to execute the real-time simulation using the Typhoon HIL SCADA system and Python-based co-simulation is created in this chapter. The real-time simulation demonstrates the proposed framework’s effectiveness in observing the distribution network’s voltage profile due to real-time variation in reactive power from the PV.
