Advanced integrated AC-DC systems for energy efficient buildings and communities in Canada

电力对国家基础设施系统(能源、水、通信、交通、卫生等)的发展至关重要。它们构成了现代社会的纤维。通过为更清洁和可持续的工业化未来提供新技术，电力将继续在解决现代能源危机方面发挥关键作用。电网正在经历着革命性的变化。现有的交流基础设施将使先进的直流电力系统和信息通信技术所占的比例越来越大，这些系统由更高效和可靠的能源利用以及更容易整合替代/可再生发电和存储系统推动。21世纪将朝着更多的直流电网发展，包括直流建筑、微电网，以及直流输电和配电的更广泛使用。 UBC在温哥华校区设定了很高的目标，并在能源效率、可持续性和减少温室气体方面做出了重大承诺。拟议的研究计划将利用哥伦比亚大学的校园作为一个生活实验室框架--校园发展单位、研究人员、学生和工业合作伙伴的合作伙伴--在以下重点领域开展研究：a)使用实时智能电表数据以及安装的电力电子设备和创新的控制算法，以改善带有直流负载的交流配电和建筑物的电能质量，以最大限度地减少全系统的能源损失；b)设计可以方便和经济地部署在商业和住宅(净能源零)建筑中的模块化电力电子设备，并整合本地能源和存储；C)确保交直流一体化系统的动态稳定性，为各种电源和负载的智能“即插即用”连接开发分布式和可扩展的解决方案；d)开发电力线通信技术，用于24/48/380 VDC系统和开关设备的实时控制；以及e)通过负荷和发电管理，制定优化AC/DC组合电网和电动汽车作为移动资源的策略。研究成果将在UBC校园进行展示，以提高其能源利用率。

The electric power has been critical to the development of the national system of infrastructures (energy, water, communications, transportation, health, etc.) that constitute the fiber of modern societies. Electrical energy will continue to play a key role in solving the modern energy crisis by offering new technologies for a cleaner and sustainable industrialized future. The power grid is undergoing evolutionary changes. The existing AC infrastructure will see increasing proportion of advanced DC electrical systems and information-communication technologies that are driven by more efficient and reliable utilization of energy and ease of integrating alternative/renewable generation and storage systems. The 21st century will see evolution toward more DC grids including DC buildings, microgrids, and wider use of DC transmission and distribution. UBC has set high goals and initiated significant undertakings on its Vancouver campus regarding energy efficiency, sustainability, and reduction of greenhouse gases. The proposed research program will utilize the UBC's Campus as a Living Laboratory framework - a partnership of campus development units, researchers, students, and industrial partners - to carry out research in the following focus areas: a) Use of real-time smart meter data together with installed power electronic equipment and innovative control algorithms for improving the power quality of the AC distribution with DC loads and buildings to minimize the system-wide energy losses; b) Design of modular power electronic devices that can be readily and economically deployed in commercial and residential (net-energy-zero) buildings with integration of local energy sources and storage; c) Ensure the dynamic stability of the integrated AC-DC systems and develop distributed and scalable solutions for intelligent "plug-n-play" connectivity of various sources and loads; d) Develop power line communications technologies for real-time control in the 24/48/380 VDC systems and switchgear; and e) Develop strategies for optimizing combined AC/DC grid with electric vehicles as mobile resource through load and generation management. The research results will be demonstrated on the UBC campus to improve its energy usage.
