Development of numerically efficient real-time simulation models and stability assessment tools for power-converter-based AC-DC grids

The integration of large-scale renewable energy sources in power grid is challenging and requires new power transmission infrastructure such as high voltage Direct Current (DC) transmission and interconnected AC-DC grids. Real-time power system digital simulators are essential for the development of new AC-DC grid technologies. The aim of this MITACS project is to develop numerically efficient offline and real-time simulation technologies for the emerging AC-DC grids. The objectives of the research include: (1) the development of new power converter models based on Xilinx Versal platform to increase the real-time simulation performance and capability; and (2) the development of stability assessment tools using frequency-dependent impedance models and small signal models for fast converter control design and prototyping. It is expected that the results of this project will greatly enhance the capabilities of state-of-the-art transient simulation tools and will facilitate the analysis and development of the AC-DC grid technologies.
