Advanced architecture and interfacing technologies of real time power-hardware-in-the-loop simulation

安全的可再生能源，如太阳能和风能，由于其减少温室气体排放和对化石燃料依赖的潜力而越来越受欢迎。然而，可再生能源也往往依赖于当时的天气条件，导致能源供应时断时续和不可预测，这对电力用户和供应商都造成了电力质量问题。这一困难可以通过开发低压微电网基础设施来克服，该基础设施可以直接与分布式可再生能源接口，并采用智能控制机制来调节电网中可用电力的有效使用和稳定性。 智能微电网的设计和评估面临挑战。没有合适的模拟器可以同时模拟电源和通信设备。由于电力设备中存在大量的非理想元件，仿真与实际系统之间还存在很大的技术差距。基于电力电子的电力硬件在环（PHIL）平台可以通过提供用于评估新型微电网设计的半物理系统来帮助克服这些挑战。物理（非模拟）组件，如电力设备和通信设备，然后可以被纳入测试微电网，这将像一个实际的微电网安装执行。来自天气源和外部电网基础设施（例如中压公共电网）的能量可用性可以完全由计算机控制和模拟，并且它们的响应通过电力电子接口转换和放大。微电网与这些外部电源的实际相互作用将被模拟，以提供对电能质量和电网稳定性的上级评估。电源将在PHIL平台和GUT之间循环，这将为长时间的评估提供高效率。 将构建一个30 kVA PHIL系统和一个测试中的微电网，以在实验室环境中运行。完整的评估平台将是小型的，高效的，实用的，准确的和完全可控的不断变化的环境数据和外部电网运营。PHIL平台将弥合理论模拟和实验室环境中的实际应用之间的技术差距。该计划将培养10名HQP（2名博士，3硕士和5 USRA），他们将获得经验，并产生电力电子和电力系统的新知识。拟议的系统将促进加拿大真实的时间仿真平台制造商和微电网供应商的技术和业务发展。此外，加拿大的研究中心和电力设备制造商将拥有一个具有成本效益的，紧凑的，完全可控的，可靠的PHIL模拟器，以评估未来小电网应用的新兴电网和电力设备。

Safe, renewable sources of energy, like solar and wind power, are gaining popularity due to their potential to reduce greenhouse gas emissions and dependency on fossil fuels. However, renewable energy is also often dependent on prevailing weather conditions, leading to a sporadic and unpredictable energy supply, which creates power quality issues for both users and providers of electrical power. This difficulty can be overcome by developing low voltage microgrid infrastructures that can interface directly with distributed renewable energy sources and employ smart control mechanisms to regulate the efficient use and stability of the available power in the grid. There are challenges to the design and evaluation of an intelligent microgrid. There are no appropriate simulators to simulate power and communication devices at the same time. And it is well-known that there is also a large technology gap that lies between simulation and practical systems, as there are a lot of non-ideal components in power apparatuses. A Power-Electronics-based Power-Hardware-In-the-Loop (PHIL) platform can help to overcome these challenges by providing a semi-physical system for evaluation of novel microgrid designs. Physical (not simulated) components, like power apparatuses and communication devices, could then be incorporated in a test microgrid, which would perform like an actual mircogrid installation. Energy availability from weather sources and the external grid infrastructure (e.g. medium voltage public grid networks) can be fully controlled and simulated by computers, and their responses converted and amplified by power electronics interfaces. Actual interactions of the microgrid with these external power sources will be simulated in a way that will provide superior evaluations of power quality and grid stability. The power will cycle between the PHIL platform and the GUT, which will provide high efficiency for prolonged periods of evaluation. A 30kVA PHIL system with a Microgrid under test will be constructed to run in a Lab environment. The complete evaluation platform will be small, efficient, practical, accurate and fully controllable for changing environmental data and external grid operations. The PHIL platform will bridge the technical gap between theoretical simulation and practical applications in a Lab environment. The proposed program will train 10 HQP (2 Ph.D., 3 M.Sc. and 5 USRA), they will gain experience and generate new knowledge of power electronics and power systems. The proposed system will facilitate technology and business development for both real time simulation platform manufacturers and microgrid providers in Canada. Furthermore, Canadian research centres and power apparatus manufacturers will have a cost-effective, compact, fully controllable, reliable PHIL simulator to evaluate emerging grids and power apparatuses for future small grids applications.
