Power system simulators represent an essential and economical system for studying and designing power system networks, including in the context of power distribution and utilization. However, the power semiconductor model in modern simulators, e.g. PSCAD, is only based on an ideal switch with conducting and disconnecting stages, it does not account for the actual and detailed characteristics of power semiconductors during switching. Thus, it cannot simulate the efficiency and thermal behavior of power electronics converters in modern power systems such as the renewable energy converters in Microgrids. In this work, a comprehensive investigation into the methodology of power system simulation associated with modern power semiconductors will be carried out and the simulated results will be experimentally verified. At the end of the project, a quick, accurate and reliable power system simulator will be produced. The project will be in tight collaboration with the Manitoba HVDC research Centre (the industrial partner of the project) and is based on their Power System Simulation software product, PSCAD. The resultant simulator of this research project will assist engineers in Utility Companies, such as Manitoba Hydro, with effective and rapid planning, design and research on future power grids. It will also benefit the manufacturers of power electronics apparatuses, e.g. solar inverters, to evaluate the efficiency and power density of their products. Further, 1 PostDoc, 1 PhD, 1 MSc and 4 summer BSc students will be trained in the project. These HQP will learn cutting-edge technologies and will be able to contribute to the Canadian Power and Energy industry in the future.

电力系统模拟器代表了研究和设计电力系统网络的基本和经济的系统，包括在发电和利用的背景下。但是，现代模拟器中的功率半导体模型，例如PSCAD仅基于带有导电和断开阶段的理想开关，它不能说明开关过程中功率半导体的实际和详细特征。因此，它无法模拟现代电力系统中电力电子转换器的效率和热行为，例如微电网中可再生能量转换器。在这项工作中，将对与现代功率半导体相关的电力系统模拟方法进行全面研究，并将在实验验证模拟结果。在项目结束时，将生成快速，准确和可靠的电源系统模拟器。 该项目将与Manitoba HVDC研究中心（该项目的工业合作伙伴）紧密合作，并基于其Power System Simulation Software产品PSCAD。该研究项目的最终模拟器将协助实用公司（例如曼尼托巴水电）的工程师，并在未来的电网上进行有效，快速的计划，设计和研究。它还将受益于电力电子设备的制造商，例如太阳逆变器，以评估其产品的效率和功率密度。此外，将在该项目中对1个博士后，1位博士学位，1个MSC和4个夏季BSC学生进行培训。这些HQP将学习最先进的技术，并能够在未来为加拿大的力量和能源行业做出贡献。
