Research and Development of Advanced Techniques for EMT Simulation of Modern Electrical Energy Systems

现代电能系统的复杂性随着智能电网的发展以及可再生分布式能源和电力电子的使用增加而迅速增长。这些系统的开发和运行只有在高度复杂的计算机模型和程序的帮助下才有可能实现。世界各地的控制中心和研究机构的数千名工程师正在全职开发模型，并随后进行各种研究。准确和快速的模拟可以实现未来电网的安全设计和优化运行，并可以防止潜在的停电和故障;然而，现有的工具远远落后。加拿大在为电力系统开发解决办法和计算机化工具方面一直处于领先地位。马尼托巴水电国际有限公司和RTDS技术公司的电力系统技术中心。是两家领先的加拿大公司，正在开发最先进的程序PSCAD和RTDS模拟器，成为世界各地电力系统离线和实时瞬态仿真的行业标准。这笔赠款设想由UBC的Jatskevich博士领导的研究小组与这两个工业合作伙伴进行非常密切的合作，以开发先进的技术，用于模拟具有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功率转换器的准确和有效的能源模型; 2）开发用于离线和实时系统级研究的更有效的功率转换器模型; 3）开发用于具有大量电力电子接口能源资源的系统（例如大型风力和光伏园区）的自动聚合和模型简化的有效技术和工具;以及4）开发用于具有不同时间步长的电力网络的混合仿真的多域解决方案和接口技术，以更有效地利用可用的仿真程序和硬件。这些功能将帮助加拿大公司引领行业的变革。

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.
