Title of the paper: Extending the Electromagnetic Transient (EMT) Simulation Programs for Evolving Power Grids


Abstract: Mathematical modelling and computer simulations enable the rapid growth of many technologies that improve economic development and quality of life. The complexity of modern electrical energy systems is rapidly growing with evolving intelligent energy grids and increased utilization of renewable/distributed energy resources and power electronics. The development and operation of such systems are only possible with the application of highly sophisticated mathematical models and computer simulation tools. Thousands of engineers in control centers and research facilities worldwide are working to develop models of various components and systems and conduct computer studies. Accurate and fast simulations enable safe design and optimal operation of future electric grids and may prevent potential blackouts and failures. The widely accepted electromagnetic transient (EMT) programs such as PSCAD, RTDS, EMTP-RV, Opal-RT’s RT-LAB, Matlab’s SimscapeElectrical, and Powertech Labs’ transient stability DSATools, etc. are now extensively used worldwide as industry-standard simulation tools. However, the existing tools are lagging behind the modern needs. Specifically, the models of electrical machines and power electronic converters are typically the computational bottleneck in the EMT programs and real-time simulators. These components usually require very small simulation time-step, are computationally expensive, and limit the system size that can be practically studied. At the same time, there is a strong need to simulate larger systems with many rotating machines and switching converters using limited computational resources. The presentation will introduce some of the research efforts carried out at UBC’s Electrical Power and Energy Systems group. We will discuss computationally advanced models that can significantly extend the range of applications of such transient simulation tools.
