The complexity of modern electrical energy systems is fast increasing with the growing use of renewable sources and power electronics, further adaptation of DC technologies, evolving smart energy grids and integration with communication systems and sensors. Computer simulations enable the safe design and optimal operation of present and future electric grids. Thousands of engineers in control centers and research facilities around the world are working full-time developing models and conducting studies. Since the simulations are used many times (often iteratively), the accuracy and efficiency of models and the capability of tools to analyze the system dynamics (i.e. extract information for analysis of stability) are very important. Even a fractional increase in simulation speed and expanded capabilities may result in significant savings worldwide and prevent potential blackouts and failures. Canada has been a leader in developing state-of-the-art solution approaches and computerized tools that enable the design and operation of electric power systems of various scales. The electromagnetic transient programs (known as EMT or EMTP) e.g. ATP, Microtran, EMTP-RV, PSCAD, RTDS, RT-LAB, the Matlab's Simscape Electrical, and Powertech Labs transient stability tools DSATools, etc., all have been originated and/or developed by Canadian researches and are now overwhelmingly used throughout the world as industry-standard tools. The proposed research continues the UBC's long-time tradition in advancing the modelling, simulation, and analysis of power grids. We are developing the most computationally efficient models of devices with rotating electrical machines and switching converters. The goal is to enable the next generation of simulation tools needed to address the widening range of transient phenomena in power systems with an increasing presence of power electronics. The future simulation tools will have the capabilities to very effectively analyze the system, identify any potential or existing problems and assist in providing a solution, while being scalable and affordable. Our research envisions interface/integrate/mix EMTP- and state-variable-type solutions as well as dynamic and static phasor-type solutions, where each approach may be applied on a subsystem level making the best use of each engine while obtaining the desired accuracy and resolution needed for each part of the system. We are focusing on establishing the so-called impedance-based models that can be numerically constructed based on existing EMT simulation engine and subsequently used to provide new information for system-level analysis in a wide range of frequencies covering supper- and sub-synchronous resonances and controller-related interactions. The new models, solution approaches, and their realization in simulators will become available to researchers and engineers in Canada and worldwide, enabling wider integration of renewable sources and the design of a better energy grid.

随着可再生能源和电力电子设备的使用不断增加、直流技术的进一步采用、智能电网的发展以及与通信系统和传感器的集成，现代电能系统的复杂性正在迅速增加。计算机模拟可以实现当前和未来电网的安全设计和优化运行。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进行研究。由于模拟被多次使用（通常是迭代），因此模型的准确性和效率以及工具分析系统动力学的能力（即提取信息以进行稳定性分析）非常重要。即使模拟速度和扩展功能的小幅提高也可能会在全球范围内带来显着的节省，并防止潜在的停电和故障。加拿大在开发最先进的解决方案和计算机化工具方面一直处于领先地位，这些解决方案和计算机化工具能够实现各种规模的电力系统的设计和运行。电磁瞬态程序（称为 EMT 或 EMTP），例如ATP、Microtran、EMTP-RV、PSCAD、RTDS、RT-LAB、Matlab 的 Simscape Electrical 和 Powertech Labs 瞬态稳定工具 DSATools 等，均由加拿大研究人员原创和/或开发，目前在全球范围内广泛使用世界作为行业标准工具。 拟议的研究延续了 UBC 在推进电网建模、仿真和分析方面的长期传统。我们正在开发具有旋转电机和开关转换器的计算效率最高的设备模型。其目标是提供下一代仿真工具，以解决随着电力电子设备不断增加而出现的电力系统中不断扩大的瞬态现象。未来的仿真工具将能够非常有效地分析系统，识别任何潜在或现有的问题，并协助提供解决方案，同时具有可扩展性和经济性。我们的研究设想了接口/集成/混合 EMTP 和状态变量型解决方案以及动态和静态相量型解决方案，其中每种方法都可以应用于子系统级别，从而充分利用每个引擎，同时获得所需的精度以及系统每个部分所需的分辨率。我们专注于建立所谓的基于阻抗的模型，该模型可以基于现有的 EMT 仿真引擎进行数值构建，随后用于为涵盖超同步和次同步谐振的广泛频率范围内的系统级分析提供新信息和控制器相关的交互。新模型、解决方案及其在模拟器中的实现将提供给加拿大和世界各地的研究人员和工程师，从而实现更广泛的可再生能源整合和更好的能源网络的设计。
