Research

Power Systems

The planning, real-time monitoring and security of future power grids requires modeling and analysis capabilities beyond those available presently. Existing models are becoming obsolete as new technologies such as renewables and power electronic based devices become more prevalent, and traditional power flow simulation algorithms lack the robustness and scalability that is needed to represent combined transmission and distribution systems over all dynamics and contingencies. Our work is based on a unique equivalent split circuit formulation that that enables adaptation and application of techniques that were developed for circuit simulation to robustly analyze power grids. Our software tool, SUGAR, provides a foundation for: i) incorporating transmission and distribution models that capture true physics behavior; ii) unifying steady state, dynamics and transient analyses; iii) assessing feasibility and solution of optimal power flow conditions.

Integrated Circuits

While the end of CMOS scaling is now in sight, the advancement of integrated circuits and systems remains a top priority for the electronics industry. A significant portion of our research has been focused on methodologies that support affordable design in sub-20nm CMOS technologies, but much of that work also includes opportunistic integration of emerging heterogeneous technologies that are compatible with the CMOS. We further explore use of emerging materials and devices (e.g. magnetics, resistance change, phase change, etc.) that provide new computational or storage capabilities when configured in new forms, or applied to specific architectures. Several of our projects target specific system applications in domains such as brain and human interfaces.

Secure Hardware

With the continued off-shoring of advanced integrated circuit (IC) manufacturing facilities, the ability to fully secure the IC manufacturing supply chain is increasingly challenging. While commercial-off-the-shelf (COTS) programmable solutions such as FPGAs and microprocessors are a viable alternative to a custom ASIC (application specific integrated circuit), it is generally at a significant cost in terms of performance-at-power (PaP). Our research is toward developing methods to design and fabricate ICs in untrusted supply chains while keeping the sensitive IP from the manufacturer. We further consider techniques to mitigate a malicious third party’s ability to alter the design during manufacturing, along with making it more difficult for others to perform in-the-field reverse engineering of critical IP.

Protecting the power grid with circuit simulation methods

In December 2015, Russian hackers allegedly pummeled Ukraine’s power grid, disrupting the flow of electricity for nearly a quarter-million Ukrainians. Then, in December 2016, roughly a year after the first attack, the hackers struck again. But this time, they targeted an electric transmission station in Kiev, the capital of Ukraine. Each cyberattack lasted no more than six hours, but security experts were still alarmed: hackers had just demonstrated their ability to infiltrate the grid and drastically alter the flow of society.
