Big Data Applications in Smart Grids: Benefits and Challenges 🗓

— utility industry sources, field measurements, devices, databases, weather, market, management, processing …

Webinar Date: Thursday, April 13, 2017
Time: 10:00 AM (PDT)
Speaker: Mladen Kezunovic, Regents Professor, Director Smart Grid Center, Texas A&M University
Location: on the Web
Cost: none

Event Details & Registration: “>

Summary: The issue of Big Data (BD) was introduced relatively recently as enormous amounts of data became available through the space exploration, weather forecasting and medical biogenetic investigations. Social media and outlets such as Google, YouTube, Facebook and others have also faced similar problems of handling huge data sets.
The focus of this webinar is on different BD sources in the utility industry that range from field measurements obtained by substation/feeder intelligent electronic devices, to specialized commercial and/or government/state databases: weather data of different types, lightning detection data, seismic data, fire detection data, electricity market data, vegetation and soil data, etc.
Due to the massive amount of such data (terabytes) available in real time, and through historical records, processing and management of such data requires revisiting data analytics used in the BD industries such as banking, insurance and health care. This webinar will point out the BD characteristics in the power industry where the temporal and spatial properties, as well as correlation to the power system and component models, are necessary for efficient data uses.

Understanding Stimulated Brillouin Scattering with a Multiphysics Approach in COMSOL 🗓

— optical fibers, critical level, electrostrictive stress, acoustical phonons, experimental results …

Webinar Date: Thursday, April 6, 2017
Time:11:00 AM (PDT)
Speaker: Dr. Carl Meinhart, UC-Santa Barbara; Mads Herring Jensen, COMSOL
Location: on the Web
Cost: none

Event Details & Registration:

Summary: If you are interested in learning how to model stimulated Brillouin scattering (SBS) in COMSOL Multiphysics®, then tune into this webinar with guest speaker Carl Meinhart of Numerical Design, Inc. and the University of California, Santa Barbara.
SBS is commonly observed in long lengths of optical fiber, where the electromagnetic intensity exceeds a critical level and there is sufficient distance for the SBS to accumulate. There has been renewed interest in SBS, as it is now feasible to microfabricate photonic chips that exhibit SBS.
In this webinar, we present a multiphysics approach for simulating SBS in the COMSOL® software. First, optical whispering gallery modes are predicted. Next, they are combined with the photoelastic tensor to estimate the 3D electrostrictive stress distribution, which is used to simulate 11-GHz acoustical phonons. Finally, the SBS gain is calculated by integrating the overlap modes between the pump photons and acoustic phonons. The results are compared to experimental data (Hansuek et al., 2012), which reports Q factors approaching 875 million.

Dr. Carl Meinhart is a professor of mechanical engineering at the University of California – Santa Barbara (UCSB). He obtained his PhD from the University of Illinois in 1994. Since coming to UCSB in 1996, his research has focused on developing microfluidic devices and investigating their fundamental transport mechanisms.

In addition to being a professor at UCSB, Dr. Meinhart is the founder and CEO of Numerical Design, Inc., which is a COMSOL Certified Consultant. Dr. Meinhart is a fellow of the American Physical Society.

Power Components for Battery Applications 🗓

— flexibility, scalable, design cycle, reduced cost, weight, size, efficiency, power density …

Webinar Date: Tuesday, April 4, 2017
Time: 5:00 AM (PDT)
Speaker: Travis Williams, Vicor
Location: on the Web
Cost: none
RSVP: required
Event Details & Registration:

Summary: Today, many systems from electric vehicles and home energy storage to communications infrastructure, use batteries to enable portable power or provide a fallback in the event that mains power fails. If demand for batteries continues to grow, engineers need an easier approach to designing battery-powered systems. In particular, the output voltage of batteries can vary significantly; power systems must deliver constant voltage to the load and act as a current source to charge the battery; and there is a continual demand for higher efficiency. This webinar explains how flexible power components can be used to shorten the design cycle, simplify the power system and reduce cost, weight and size while increasing efficiency.
Topics covered include:
• Why wide input and output voltage ranges are important
• How to design scalable power systems to meet current and future needs
• Reducing costs by using flexible components
• Maximizing power density and efficiency in systems with batteries
Travis Williams has extensive experience in power electronics design. He has worked at Vicor for two years and previously held a variety of engineering roles for 14 years. His patents include one to estimate the state of charge of a battery. He holds a BSEE from Brigham Young University and an MBA from the University of Southern Maine.

Summary: Gallium Nitride (GaN) based transistor technology’s characteristics of very high current density combined with high voltage operation have held promise to vastly improve many microwave circuit applications that presently utilize Gallium Arsenide (GaAs) devices. Today, GaN transistors are capable of high voltage operation while simultaneously demonstrating fT & fMAX characteristics more typical of lower voltage GaAs PHEMT devices. The potential benefits of GaN device characteristics combined with monolithic microwave integrated circuit (MMIC) technology are many. Highly efficient switched modes of power amplifier operation should be possible at higher output power levels and frequency. High output impedance typical of transistors operated at three to five times the voltage of GaAs should facilitate lower loss matching networks due to the reduced transformation ratio. Alternately, transistor periphery and corresponding output power could be dramatically increased while maintaining impedance transformation ratios similar to that of existing GaAs PHEMT amplifiers. The higher output power density of GaN devices should lead to greatly reduced die size for GaN implementations of existing power amplifier functions. The improved heat flow realized by the high thermal conductivity Silicon Carbide (SiC) substrate material should allow for acceptable junction temperatures even with the much higher power dissipation. Very high power switches could be designed by using large control voltages and taking advantage of the high current capability (high Imax) of GaN. While the advantages of GaN are manifest, many of the features that make GaN transistors attractive can be shown to create significant issues that are typically not encountered with lower voltage technologies. In this talk, examples and scenarios are discussed highlighting the benefits and issues associated GaN MMIC technology.
