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日益增长的使用，DC技术的进一步适应，不断发展的智能能网格以及与通信系统和传感器的集成，现代电气能源系统的复杂性正在迅速增加。计算机模拟实现了当前和未来电网的安全设计和最佳操作。全球控制中心和研究设施中成千上万的工程师正在全日制开发模型和进行研究。由于模拟使用了多次（通常是迭代），因此模型的准确性和效率以及分析系统动态的工具的能力（即提取稳定性分析的信息）非常重要。即使是模拟速度和扩展功能的分数提高也可能导致全球大量节省，并防止潜在的停电和失败。加拿大一直是开发最先进的解决方案方法和计算机化工具的领导者，这些方法可以使各种尺度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，RTD，RT-LAB，MATLAB的SIMSCAPE电气和PowerTech Labs瞬态稳定性工具DSATOOLS等都由加拿大研究来源和/或开发，并且现在由全球范围内用作行业标准的工具。 拟议的研究延续了UBC的长期传统，以推进电网的建模，模拟和分析。我们正在开发具有旋转电机和开关转换器的设备的最有效的设备模型。目的是实现下一代模拟工具，以解决功率电子设备越来越多的电力系统中瞬时现象的扩大范围。未来的仿真工具将具有非常有效地分析系统，确定任何潜在或现有问题并协助提供解决方案的能力，同时可扩展和负担得起。我们的研究设想了界面/集成/混合EMTP-和状态变量型型解决方案以及动态和静态的相拟合型解决方案，其中每种方法都可以应用于子系统级别，从而使每个发动机的最佳使用，同时获得系统每个部分所需的所需精度和分辨率。我们专注于建立所谓的基于阻抗的模型，这些模型可以基于现有的EMT仿真引擎进行数值构造，随后用于为系统级分析提供新的信息，以涵盖涵盖晚餐和同步共振和控制器相关的相关相互作用的各种频率。新的模型，解决方案方法及其在模拟器中的实现将为加拿大和全球的研究人员和工程师提供，从而使可再生能源的更广泛整合以及更好的能源网格的设计。
