Evolution of Short Term Unit Scheduling Solutions in Power System Operations
Virtual: https://events.vtools.ieee.org/m/416996Will provide a high level brief overview of the solutions and algorithms evolved over the last several decades to solve the short term unit scheduling problem. The focus is on the practically most used solutions to power systems operations. The discussion will include priority merit list, dynamic programming, Linear Programming, Lagrangian relaxation, Augmented Lagrangian relaxation, and the game changer Mixed Integer Program (MIP). The mathematical breakthroughs and efficient search algorithms used in recent MIP commercial solvers made MIP the algorithm of choice widely adopted by the power systems industry to solve such highly complex, non-convex, and combinatorial optimization problem. The huge reduction in the MIP optimization solution time, the ease of mathematical constraints modeling, and the increased solution quality transformed the real-time applications and made it possible to model large number of complex resources’ types like combined cycle units, startup times and cost, transition time and cost, dynamic ramp rates as functions of resources MW. These advances in MIP made it possible to also include unprecedented large set of cross-resources and cross-time intervals coupling constraints such as transmission, and environment constraints in optimizing operations in day-ahead and real-time applications. As illustrative example, the presentation will highlight the current large-scale mathematical MIP model sizes, solution times, and the optimal MIP integer gaps achieved in both day-ahead and real-time market applications at the California ISO’s production system.

It is less known that some key functionalities for MEMS/NEMS, nano-optics and metasurfaces can be uniquely unlocked by the combination of graphene and silicon carbide . Over the last decade, we have developed an epitaxial graphene on silicon carbide on silicon technology that inherently delivers both capabilities. This platform allows to fabricate any complex graphene flat or 3D nanopattern in a site – selective fashion, ie without etching of the graphene, at the wafer -scale and with sufficient adhesion for integration . We will review the learnings from the development of this technology and some of its most promising applications. We show that the sheet resistance of epitaxial graphene on 3C-SiC on silicon is comparable to that of epitaxial graphene on SiC wafers, despite substantially smaller grains. We also indicate that the control of the graphene interfaces, particularly when integrated, can be a more important factor than achieving large grain sizes . In addition, we show that well- engineered defects in graphene are preferable to defect -free graphene for most electrochemical applications. Promising examples of application of this technology in the More- than – Moore domain include integrated energy storage , MIR sensing and detection , and sensors for electro-encephalography for brain-computer interfaces ..

Unintentional Expertise: How the Necessity of Working with PID Controllers Across Multiple Domains Fundamentally Improved My Understanding of Control Theory and Practice
Room: SCDI - 2116, Bldg: Sobrato Campus for Discovery and Innovation - SCDI, 500 El Camino Real , Santa Clara , California, United States, 95053Being fresh out of grad school (FOOGS) in 1988, I reacted to PID controllers in the usual way for young Ph.D. recipients: with a certain “hands-off” smugness. Yet, as the years in industry wore on, I kept encountering these ubiquitous devices in practice and had to learn to deal with them, understand them, and roll my own. What I found led me to consider PIDs, not as a separate art from advanced methods, but as a fundamental building block which can be used as part of most controllers, simple or advanced. It seemed that – at least in the mechatronics world – PIDs were considered too simple for much interest in academia while practicing engineers didn’t seem to care why they were working. In the process world, where PIDs studied far more, the issues and methods of mechatronic PIDs seemed like obscure corner cases. Depending upon the teaching text, issues of sampling and digital representation may have been completely omitted. There were other surprises. While PIDs were almost universal and standard, they were almost never unified or standardized. Furthermore, what seemed to limit performance was not the structure of the controller itself, but the lack of accurate system/process models based on repeated physical system measurements. Finally, the mechatronic and process PID goals and foibles were not that different once one considered the different system, time constant, and measurement constraints. We will discuss these issues with the goal of getting a more unified view of PIDs across our application domains. We will provide a handful of common PID forms and show how they are related, so that we can approach any PID structure with the same analytical approach. We will finally look forward to how PIDs can be used, not only as a fundamental teaching tool for explaining control outside of our research circles, but as a critical component for advanced control methods. As the great Paul Simon might say, “Mama don’t take my PID away.” Speaker(s): Dr. Danny Abramovitch , Agenda: 5:45 - 6:15 : Networking and light dinner 6:15 - 7:15 : Talk and Q&A 7:15 - 7:45 : Networking Room: SCDI - 2116, Bldg: Sobrato Campus for Discovery and Innovation - SCDI, 500 El Camino Real , Santa Clara , California, United States, 95053
