With the focus on environmental sustainability and energy security, power system planners are looking at renewable energy as supplements and alternatives. But such generation sources have their own challenges - primarily intermittency. It is expected that the smart grid – due to its inherent communication, sensing and control capabilities – will have the ability to manage the load, storage and generation assets (including renewables) in the power grid to enable a large-scale integration of distributed generation. In a smart grid, information about the state of the grid and its components can be exchanged quickly over long distances and complex networks. It will therefore be possible to have the integration of sustainable energy sources, such as wind, solar, off-shore electricity, etc. for smoother system operation. But in order for this to be possible, the electric utility will have to evolve, and change their ways of operation to become an intelligent provider of these services. This lecture introduces the operational characteristics of renewable energy sources, and various aspects of the smart grid - technology, standards and regulations. It also addresses the interplay among distributed generation, storage and conventional generation to provide an efficient operational strategy in the context of the smart grid.

This is Part I of a Two Part Talk on OFDM. The abstract below is for both Part I and II: The main benefit of OFDM is its ability to cope with severe multipath channel conditions without the need for complex equalization filters. How does it accomplish this? The short answer: by "dividing and conquering." It partitions a high-data-rate signal into smaller low-data-rate signals so that the data can be sent over many low-rate sub-channels. The Time/Frequency relationships are presented with a figure that facilitates a straightforward understanding of the OFDM partitioning process. We emphasize the important role of the cyclic prefix (CP). We show how it allows us to change linear convolution into circular convolution, thereby purging any transients, which helps to maintain waveform orthogonality at the receiver. OFDM waveform synthesis is covered in detail. Also, the spectral properties of Real and Imaginary signals are reviewed. We further consider the peak-to-average power ratio (PAPR) in OFDM, and how the desire for small PAPR has given rise to a special variant of OFDM called single-carrier OFDM (SC-OFDM). Finally, we illustrate applications of this elegant technology in standards such as 802.11 and LTE.

Abstract. After providing a brief introductory survey of recent and current efforts at the Center for Wireless Information Systems and Computational Architectures (WISCA), and observations on the future of RF systems, we introduce our efforts on the next generation of coarse-scale heterogenous processor development. On our project – entitled Domain-Focused Advanced Software-Reconfigurable Heterogeneous (DASH)-System-on-Chip (SoC) that operates under the DARPA Domain-Specific System-on-Chip (DSSoC) program – we are constructing both a development framework and an example SoC. Our SoC and framework will provide efficiency that approaches that of full-custom integrated circuits while enabling ease of programming that is similar to that of traditional scalar processors. To achieve this goal, we pursue significant progress in application ontological analysis, program and debugging software tools, intelligent on-chip resource management, flexible high-performance on-chip networking, and advanced task-specific accelerators. Additionally, to assure usefulness to DoD RF applications, we work with multiple traditional defense contractors on transitioning the DASH-SoC to example systems. We lead a broad team from academia, commercial industry, and traditional defense contractors. Biography. Prof. Daniel W. Bliss (bliss.asu.edu) is a Professor in the School of Electrical, Computer, and Energy Engineering at Arizona State University and a Fellow of the IEEE. He is also the Director of ASU’s Center for Wireless Information Systems and Computational Architectures (wisca.asu.edu). Dan received his Ph.D. and M.S. in Physics from the University of California at San Diego (1997 and 1995), and his B.S. in Electrical Engineering from ASU (1989). His current research focuses on advanced systems in the areas of communications, radar, precision positioning, advanced computational systems, and medical monitoring. Dan has been the principal investigator on numerous projects including sponsored programs with DARPA, ONR, Google, Airbus, and many others. He is responsible for foundational work in electronic protection, adaptive multiple-input multiple-output (MIMO) communications, MIMO radar, distributed-coherent systems, and RF convergence.

Atlanta WIE is co-hosting this event next Wednesday with several notable Georgia women in STEM, including Cassandra Wheeler, Regional Director for Georgia Power, and our own Theresa Brunasso, IEEE Region 3 Director-elect and engineering entrepreneur. In addition to hearing about their journeys, there will be breakout rooms for Q&A and a speed networking session to meet other local women in STEM. (The speed networking is fun, give it a shot!) See the attached flyer for information, and register (https://hopin.com/events/celebrating-georgia-women-in-stem).

The number of publications per year on predictive control doubles every three years. The strong interest in academia is reflected in industry with two recent product releases. Both use model predictive control for high-power variable speed drives, which improves efficiency, increases rated power and lowers the overall system cost. This lecture introduces the main predictive control methods available today in a concise yet intuitively accessible way. The lesser known methods are also discussed, providing a comprehensive introduction to the subject. The first two industrial success stories are presented in detail, and their commercial benefits are explained. The lecture concludes with a critical assessment of the state-of-the-art in predictive control and points out directions for future research.
