随着智能电网的不断发展以及可再生分布式能源和电力电子产品的日益广泛使用，现代电力能源系统的复杂性正在迅速增长。只有高度复杂的计算机模型和程序才能使这些系统的开发和运行成为可能。世界各地控制中心和研究机构的数千名工程师正在全职开发模型，并随后与它们一起进行各种研究。准确和快速的模拟使未来电网的安全设计和优化运行成为可能，并可能防止潜在的停电和故障；然而，现有的工具远远落后。 加拿大在开发电力系统的解决办法和计算机化工具方面一直处于领先地位。马尼托巴省水电国际有限公司的电力系统技术中心和RTDS技术公司是两家领先的加拿大公司，它们正在开发最先进的程序PSCAD和RTDS模拟器，该程序已成为世界各地电力系统离线和实时暂态仿真的行业标准。这笔赠款设想由UBC的Jatskevich博士领导的研究小组与这两个行业合作伙伴非常密切地合作，开发先进的技术，以模拟使用可再生能源的现代电力系统，并随后增强PSCAD和RTDS模拟器的能力。这项研究将：1)开发基于旋转电机和电力变流器的准确和高效的能源模型；2)开发更高效的电源变流器模型，用于离线和实时系统级研究；3)开发高效的技术和工具，用于大型风电场和光伏园区等大量电力电子接口能源系统的自动聚合和模型简化；以及4)开发多领域的解决方案和接口技术，用于不同时间步长的电网混合仿真，以更有效地利用现有的仿真程序和硬件。这些功能将帮助加拿大公司引领行业的变革性变化。

The complexity of modern electrical energy systems is rapidly growing with evolving smart energy grids and increased use of renewable distributed energy resources and power electronics. The development and operation of these systems are only possible due to highly sophisticated computer models and programs. Thousands of engineers in control centers and research facilities around the world are working full-time developing models and subsequently conducting various studies with them. Accurate and fast simulations enable safe design and optimal operation of future electric grids and may prevent potential blackouts and failures; however, the existing tools are much lagging behind. Canada has been a leader in developing solution approaches and computerized tools for electric power systems. Power Systems Technology Centre at Manitoba Hydro International Ltd and RTDS Technologies Inc. are the two leading Canadian companies that are developing the state-of-the-art program PSCAD and RTDS Simulator that became industry standard for offline and real-time transient simulation of power systems around the world. This grant envisions a very close collaboration of research group lead by Dr. Jatskevich at UBC and these two industrial partners for the development of advanced techniques for simulation of modern power systems with renewable energy sources and subsequently enhancing the capabilities of PSCAD and RTDS Simulator. This research will: 1) develop accurate and efficient models of energy sources based on rotating electrical machines and power converters; 2) develop more efficient models of power converters for offline and real-time system-level studies ; 3) develop efficient techniques and tools for automatic aggregation and model reduction for systems with a large number of power-electronically-interfaced energy resources such as large wind and PV parks; and 4) develop multi-domain solutions and interfacing techniques for hybrid simulation of power networks with different time-steps for more efficient utilization of available simulation programs and hardware. These features will help Canadian companies to lead the transformative changes in the industry.
