Hydro Quebec Research Institute (IREQ) is currently undertaking the tasks on real-time simulation of Hydro Quebec's electric power system to better serve for the planning and operation requirement of the system. On the real-time simulation platform Hypersim developed at IREQ, IREQ is also working on the performance validation of the state-of-the-art smart grid technologies before they are implemented to Hydro Quebec's power system. Among the new technologies, wide-area monitoring and control (WAMC) has been extensively investigated to suppress inter-area oscillations in the power. As the key component of a WAMC system, phasor measurement units (PMUs) simultaneously measure electrical voltage and current phasors across a wide area of the power system. Before deploying WAMC, it is important to test and validate performance of PMUs to ensure high reliability and accuracy under different operating scenarios of the power system. Accurate PMU simulation models are also necessary when the WAMC system is tested on the real-time simulation platform of the large-scale power system. This project will implement a standard reference PMU as a virtual device in Hypersim and simulate a WAMC system completely in Hypersim by using the reference PMU as a calibration tool for actual PMU devices. The developed PMU model will consider the measurement and calculation error of actual PMU devices and design an improved phasor computation algorithm to follow the changes of the grid operation conditions. This PMU model will facilitate the real-time simulation of advanced WAMC systems before they are deployed in Hydro Quebec's transmission system in the next 5 years. The results of this research will provide a reference PMU model in the commercial software Hypersim, which will benefit other Canadian utilities to plan their WAMC deployment to increase the security and resilience of the Canadian power grid.
