Control of Small Renewable Energy Conversion Systems

可再生能源转换系统是世界上一项日益发展的能源技术。加拿大拥有大量未开发的可再生能源资源，可以在不增加二氧化碳排放的情况下满足日益增长的能源需求。加拿大在可再生能源系统的研究和部署方面落后。拟议研究的目标是设计小型可再生能源转换系统的控制系统和部件，并在这一过程中培养一批高素质的人员。本文的研究内容包括：(1)小型双馈感应风力发电机组的新型控制器设计和最优控制策略；(2)将抽水蓄能技术引入偏远地区混合动力系统的优化选型与控制方法；(3)用于小型流体动能转换系统的集成永磁发电机的磁谐齿轮系统的新设计；(4)具有储能功能的微网系统基于d-q潮流的新控制方法；(5)提出了一种新颖的控制方案，并设计了一种低成本的远程小型混合动力系统监控和数据记录系统。拟议的研究计划将带来小型可再生能源系统的新知识和创新设计。预计开发的设计将在加拿大使用。因此，这项研究将有助于促进可再生能源在加拿大的应用。这项研究还将帮助培训五名研究生有关可再生能源转换系统的知识。

Renewable energy conversion systems are a growing energy technology in the world. Canada has vast untapped renewable energy resources that can be exploited to meet the increasing energy demand without additional CO2 emissions. Canada is lagging on research and deployment of renewable energy systems. The objectives of the proposed research are to design control systems and components of small renewable energy conversion systems and in this process produce a number of highly qualified personnel. The proposed research program will contribute the following: (1) a new controller design and an optimum control strategy for small doubly fed induction generator based wind turbines; (2) a new optimal sizing and control method of adding pumped hydro energy storage to hybrid power systems for remote isolated sites; (3) a novel design of a magnetic harmonic gear system with an integrated permanent magnet generator for small hydrokinetic energy conversion system; (4) a new d-q load flow based control method for micro-grid system with energy storage; and, (5) a novel control scheme and design of a cost effective supervisory controller and data logger system for small remote hybrid power systems. The proposed research program will lead to new knowledge and innovative designs of small renewable energy systems. It is expected that the developed designs will be used in Canada. Hence this research will help enhance the application of renewable energy in Canada. This research will also help train five graduate students on renewable energy conversion systems.
