Talk Title: Energy Efficiency Enhancement Techniques in Energy Generation, Storage, and Consumption Systems
Abstract: Abstract: Power and energy consumption pose serious economic, societal, and environmental concerns in various scales of information processing applications and cyber-physical systems, ranging from battery-powered embedded systems, handheld smartphones, desktop computers and household appliances, to data centers. A joint optimization framework is necessary for energy efficiency enhancement in all the sides of energy generation, energy storage, and energy consumption.
In this presentation, I will first present my work on energy efficiency enhancement in photovoltaic (PV) energy generation and hybrid electrical energy storage systems, including (i) modeling, optimal control, and reconfiguration for combating partial shading and PV cell faults in a PV system, (ii) optimal design and control of hybrid electrical energy storage systems which can exploit the benefits of its constituent energy storage elements, and (iii) joint optimization and control.
Next I will present our work on near-threshold computing for emerging devices, which will be highly useful for future embedded and heterogeneous computing. We have proposed a device-circuit-architecture cross-layer optimization framework. At the device level we design and optimize deeply-scaled FinFET devices using accurate device simulators. At the circuit level we develop robust logic cells and SRAM cells based on these devices. At the architecture level we optimize datapath structure and cache memories to achieve low power and high robustness.
Biography: Biography: Yanzhi Wang graduated with Ph.D. degree from Ming Hsieh Department of Electrical Engineering at University of Southern California in Aug. 2014, under the supervision of Prof. Massoud Pedram. He graduated with B.S. degree with distinction from Tsinghua University in July 2009. Now he is a postdoctoral research associate and part-time lecturer at USC. His research interests include control and optimization of energy generation and energy storage systems, green and sustainable computing, and extremely low-power near-threshold computing and emerging technologies. He has published ~130 papers in major conferences and journals, including three best paper or top paper awards on top-tier conferences (ISLPED 2014, ISVLSI 2014, IEEE Cloud 2014), multiple best paper nominations and two IEEE Trans. on CAD popular papers.
