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

通过这个项目的开发工作，一个小型的研究小组从印第安纳州普渡大学印第安纳波利斯（IUPUI）将启动合作研究与丹麦合作伙伴从能源技术研究所奥尔堡大学。 我们一起-丹麦团队将研究影响电流效率和可靠性的微电网和电源转换器架构相关的挑战。 他们的方法涉及建模，仿真和实验验证新提出的架构，包括两相和四相微电网和接口电源转换器的安排。 美国团队在微电网和转换器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。 为了减少能量损失，同时提高系统效率，他们将从设计一个概念验证装置开始，以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新的电力传输方式，无论是通过线对线连接还是通过相电压，与需要更大电压变化的传统系统相比，都可以降低复杂性和成本。 具体来说，研究人员计划通过模拟、设计和实验测试来开发、分析和验证几种设计，以证明其优势。 这个发展项目实现了催化新的国际合作以推进下一代配电系统微电网工程研究的计划目标。 初步的结果也有望提高我们对新的容错电力电子转换器的故障发生后运行的潜力的理解。 如果成功，这项研究可能会导致系统效率的提高，同时减少社会和环境的成本。 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可充电汽车，而不会损失可靠性。更广泛的影响还包括对美国学生未来培训的贡献，通过一个新的IUPUI课程，“微电网系统”的准备，并通过提供一个参与印第安纳州大学的研究生第一手，在奥尔堡大学在不断增长的工程领域的职业生涯早期的国际研究经验。

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.
