CNIC: U.S.-Denmark Collaboration on Strategies to Improve Efficiency and Reliability in Microgrids

通过这一项目开发工作，印第安纳大学-普渡大学印第安纳波利斯分校(IUPUI)的一个小型研究小组将与奥尔堡大学能源技术研究所的丹麦合作伙伴开展合作研究。美国-丹麦团队将共同研究与微电网和电源转换器架构相关的挑战，这些挑战会影响电流效率和可靠性。他们的方法包括对新提出的架构进行建模、模拟和实验验证，这些架构配置了两相和四相微电网以及接口电源转换器。美国团队在微电网和变流器的建模和仿真方面的优势与丹麦合作伙伴在可再生能源系统、电力电子和能源效率方面的专业知识相辅相成。为了在提高系统效率的同时减少能量损失，他们将首先设计一个概念验证设置来模拟实际的微电网系统。该团队希望，他们的两相和四相设计将提供两种电力传输方式的新选择，通过线对线连接或通过相电压，使其与需要更大电压变化的传统系统相比，有可能降低复杂性和成本。具体地说，研究人员计划开发、分析和验证几种设计，以通过模拟、设计和实验测试来展示其优势。这一开发项目实现了项目目标，即促进新的国际合作，推进配电系统下一代微电网的工程研究。初步结果也有望提高我们对新的容错电力电子转换器的潜力的理解，这些转换器在故障发生后运行。如果成功，这项研究可能会以更少的社会和环境成本提高系统效率。最终目标是帮助建立一个新的电力分配系统，能够以最低的成本处理更多的可再生能源和更多的充电汽车，而不会损失可靠性。更广泛的影响还包括通过准备新的IUPUI课程“微电网系统”，以及通过为一名参与课程的印第安纳大学研究生提供在奥尔堡大学不断增长的工程领域的第一手、职业生涯早期的国际研究经验，为美国学生未来的培训做出贡献。

Through this project development effort, a small research team from Indiana University-Purdue University Indianapolis (IUPUI) will initiate cooperative research with Danish partners from the Institute of Energy Technology at Aalborg University. Together, the U.S.-Danish team will examine challenges associated with microgrid and power converter architectures that affect current efficiency and reliability. Their approach involves modeling, simulating and experimentally validating newly proposed architectures with arrangements of two- and four-phase microgrids and interfacing power converters. The U.S. team's strengths in modeling and simulation of microgrids and converters complement the Danish partners' expertise in renewable energy systems, power electronics and energy efficiency. With the goal of reducing energy losses while increasing system efficiency, they will start by designing a proof-of-concept setup to emulate an actual microgrid system. The team hopes that their two-phase and four-phase designs will provide a new choice of two ways to move power, either through line-to-line connection or through phase voltages, making it possible to reduce complexity and expense compared to conventional systems requiring larger voltage changes. Specifically, the researchers plan to develop, analyze and validate several designs to demonstrate the advantages, through simulation, design, and experimental tests. This developmental project fulfills the program objective of catalyzing new international collaboration to advance engineering research on next-generation microgrids for power distribution systems. Preliminary results also are expected to improve our understanding of the potential for new fault tolerant power electronics converters that operate after a fault occurs. If successful, this research could lead to increases in system efficiency with less cost to society and the environment. The ultimate goal is to help build a new electric power distribution system capable of handling more renewable energy sources and more rechargeable cars, at minimum cost and without loss of reliability. Broader impacts also include contributions to the future training of U.S. students, through the preparation of a new IUPUI course, "Microgrid Systems," and by providing one participating Indiana University graduate student with first hand, early career international research experience at Aalborg University in a growing engineering field.
