| This presentation is on the use of HYPERSIM to co-simulate cyber-physical energy systems as part of the digitalization of transmission substations under the IEC 61850 standard and the sustainment of remedial action schemes (RAS). The goal is to simultaneously analyze the interactions between the electrical, telecommunications and cybersecurity domains for a range of comprehensive studies. This innovation project at Hydro-Québec’s research institute, IREQ, supports Hydro-Québec TransÉnergie’s vision for systems convergence and automation development with respect to simulation and comprehensive performance studies. It is led internally by the automation (IEC 61850 models, algorithms and hardware, and converged vision), telecommunications (architecture), cybersecurity and system studies teams. HYPERSIM is at the core of the co-simulation platform. It is used to simulate the real-time behavior of the power system for various time domain analysis scenarios, generate and receive IEC 61850 signals by integrating data models according to the standard and guarantee the connection of automation equipment in Hardware-In-the-Loop (HIL). There were a number of technical challenges in setting up the analysis of the entire co-simulation system in the first step of the project, which focused on generation rejection and remote load shedding RAS. These included: (1) building the HYPERSIM model, in particular the design or adaptation of detailed models while guaranteeing real-time performance, under the IEC 61850 standard; (2) establishing models and tools for simulating the telecommunications infrastructure in the “discrete event” time domain mode for LAN and WAN equipments; and (3) creating numerical models of the algorithms and connecting them in HIL by integrating their IEC 61850 SCL files in HYPERSIM and in the telecommunications system. The results allowed us to study scenarios of generation rejection and remote load shedding in a power system for a large system using a 16-cores machine. The voltage and frequency behaviors corresponded to the expected settings. The disruptions in the telecommunications domain could be analyzed on the power system and on the RAS. Ongoing and future steps include extending out to other RAS functions and adding additional boxes for load-shedding in HIL, as well as improving the inclusion of IEC 61850 data models in the simulators. The expected benefits of this project for Hydro-Québec TransÉnergie are: • Analysis of telecommunications disruptions involving cybersecurity and therefore the strategic benefit of avoiding intrusions of digitalized RAS • Upstream detection of design issues • Reduction of RAS deployment time (generation rejection and remote load shedding) through comprehensive testing • Assistance with the architectural design process and proofs of concept for all items in the systems convergence and automation development program vision phases • New means of full power system optimization that offer simultaneous analysis and comprehensive testing |
