Abstract:

Application of power electronics is widespread in everyday life. Some applications are considered as “nice to have it;” in other cases, they are essential. This presentation discusses a wide variety of daily-used applications around the world. Also covered is an advanced topic, such as SMART Controller that today’s grid requires for voltage regulation, power factor regulation, unbalance voltage/current regulation, harmonic elimination and so on. A SMART Controller that is based on functional requirements and cost-effective solutions is derived from utilizing the best features of all the technical concepts that are developed until now. Final year students of electrical engineering undergraduate curriculum, post graduate students, researchers, academicians and utility engineers will benefit from attending this course. The participantswill hear from an expert who actually designed and commissioned a fewutility-grade SMART controllers since their inception in the 1990s.

Advanced semiconductor lasers:Ultra-low operating energy and heterogeneous integration with Si photonics devices

Shinji Matsuo, NTT Photonics Laboratories, Japan

Abstract: The electrical power consumed in data transmission systems is now hampering efforts to further increase the speed and capacity at various scales, ranging from data centers to microprocessors. Optical interconnects employing an ultralow energy directly modulated lasers will play a key role in reducing the power consumption. Since a laser’s operating energy is proportional to the size of its active volume, developing high-performance lasers with a small cavity is important. For this purpose, we have developed membrane DFB and photonic crystal (PhC) lasers, in which active regions are buried with InP layer. Thanks to the reduction of cavity size and the increase in optical confinement factor, we have achieved extremely small operating energy and demonstrated 4.4-fJ/bit operating energy by employing wavelength-scale PhC cavity. Reduction of the cost is also important issue because huge number of transmitters are required for short distance optical links. For this purpose, Si photonics technology is expected to be a potential solution because it can provide large-scale phonic integrated circuits (PICs), which can reduce the assembly cost compared with transmitters constructed by discrete devices. Therefore, heterogeneous integration of III-V compound semiconductors and Si has attracted much attention. For fabricating these devices, we have developed wafer-scale fabrication procedure that employs regrowth of III-V compound semiconductors on directly bonded thin InP template on SiO2/Si substrate. A key to realize high-quality epitaxial layer is total thickness, which must be below the critical thickness, typically 430 nm. Thus, membrane structure is quite suitable for heterogeneous integration. I will talk about our recent progress, focusing on ultralow-powerconsumption directly modulated lasers and their photonic integrated circuit. I will also describe progress in heterogeneous integration of these lasers and Si photonics devices.

Bio: Dr. Matsuo received a B.E. and M.E. degrees in electrical engineering from Hiroshima University, Hiroshima, Japan, in 1986 and 1988, and the Ph.D. degree in electronics and applied physics from Tokyo Institute of Technology, Tokyo, Japan, in 2008. In 1988, he joined NTT Optoelectronics Laboratories, Atsugi, where he was engaged in research on photonic functional devices using MQW-pin modulators and VCSELs. In 1997, he researched optical networks using WDM technologies at NTT Network Innovation Laboratories, Yokosuka. Since 2000, he has been researching InP-based photonic integrated circuits including fast tunable lasers and photonic crystal lasers at NTT Photonics Laboratories, Atsugi. Dr. Matsuo is a member of the IEEE Photonics Society, Japan Society of Applied Physics and the Institute of Electronics, Information and Communication Engineers (IEICE) of Japan.

TITLE: Microgrid Stability Definitions, Analysis, and Modeling

SPEAKER: Dr. Mostafa Farrokhabadi, Director of Technology at BluWave-ai, Ottawa

DATE:     Tuesday, March 17, 2020.

TIME:     Refreshments, Registration and Networking: 6:00 p.m.; Seminar: 6:30 p.m. – 7:30 p.m.

LOCATION: Ciena Optophotonics Lab, Room T129, T-Building, School of Advanced Technology, Algonquin College, 1385 Woodroffe Ave., Ottawa, ON Canada K2G 1V8.

Abstract: A microgrid is defined as a group of Distributed Energy Resources (DERs) and loads that act locally as a single controllable entity and can operate in both grid-connected and islanded modes. Microgrids are considered a critical link in the evolution from vertically integrated bulk power systems to smart decentralized networks, by facilitating the integration of DERs. Entities, such as government agencies, utilities, military bases, and universities around the world are deploying microgrids, and an increasing number of these systems are expected to be developed in the next decade. In general, stability in microgrids has been treated from the perspective of conventional bulk power systems. However, the nature of the stability problem and dynamic performance of a microgrid are considerably different than those of a conventional power system due to intrinsic differences between microgrids and bulk power systems, such as size, feeder types, high share of Renewable Energy Sources (RES), converter-interfaced components, low inertia, measurement devices such as Phase-Locked Loop (PLL), unbalanced operation, etc.

This seminar discusses the findings of the award-winning IEEE PES Task Force on Microgrid Stability Definitions, Analysis, and Modeling, which defines concepts and identifies relevant issues related to stability in microgrids. The seminar presents definitions and classification of microgrid stability, considering pertinent microgrid features such as voltage-frequency dependence, unbalancing, low inertia, and generation intermittency. A few examples will be also presented, highlighting some of the stability classes discussed during the seminar.

Speaker’s Bio: Dr. Mostafa Farrokhabadi is the Senior Director of Technology at BluWave-ai, an internationally award-winning startup offering AI-enabled control and optimization solutions for smart grids. He has more than 8 years of experience in designing mission critical grid solutions for industry and academia, including technical leadership of a $6M international consortium in Electric Grid Modernization, and Smart Grid projects with Hatch and Canadian Solar. Mostafa has authored/co-authored several high-impact technical papers and patents on intelligent control and optimization of renewable-penetrated grids.

Mostafa obtained his PhD in Electrical and Computer Engineering from the University of Waterloo. He has also studied and performed research in Sweden at KTH and Germany at KIT. During the course of his career, Mostafa has received multiple business, research, and teaching awards, including the prestigious University of Waterloo Doctoral Thesis Completion Award and Ottawa’s Forty Under 40.

Mostafa has also led the award-winning IEEE Power and Energy Society Task Force on microgrid stability, an international coalition of 21 researchers from 14 institutions investigating stability issues in microgrids. Currently, he serves as an Associate Editor of the IEEE Transactions on Smart Grid.

burgeoning careers.

Photonics and optics are finally seeing widespread adoption and significant growth into new markets. Photonic devices are being applied to sensing, communications, and even quantum computing. High speed fiber optics and highly integrated subsystems are essential to the rollout of 5G systems. There has never been a better time for research, development, and training in photonics and Photonics North is essential for developing and promoting the ecosystem.
