Applications of CPS technologies involving the power generation and/or energy conservation.

Electricity usage of buildings (including offices, malls and residential apartments) represents a significant portion of a nation's energy expenditure and carbon footprint. Buildings are estimated to consume 72% of the total electricity production in the US. Unfortunately, however, 30% of this energy consumption is wasted. Virtual energy assessment is an approach that can optimize building energy efficiency and minimize waste at a low cost with minimal expert intervention.

Abstract:
Existing platforms are built with a static network connecting microprocessor, radio, clock system, and other components. This static configuration prevents researchers from experimentally validating the trade-offs between the way that clocks are conditioned and distributed, and the performance of the embedded system. In particular, such design decisions have major impact on time synchronization.

Abstract:
This project is focused on developing a fundamental understanding of the impact of network delays and data drops using an approach that is applicable to a variety of Cyber-Physical Systems (CPS). An example of such a CPS is the power grid which includes large-scale deployment of distributed and networked Phasor Measurement Units (PMUs) and wind energy resources.

The multistep electricity price (MEP) policy has been introduced to promote energy saving, load balancing, and fairness in electricity consumption. Nonetheless, with the development of the smart grid, how to determine the quantity of electricity and at what price in a step-like fashion has not been fully investigated in the past.

Abstract:
This year, we continued our research effort on designing optimal decentralized monitoring and control mechanisms for networked infrastructure systems providing demand response services by first focusing on the example of intelligent electric transportation systems. The results are highlighted in this poster. Electric Vehicles (EV) are emerging as one of the primary solutions to make electricity demand elastic.

Abstract:
The objective of this research is to create tools to manage uncertainty in the design and certification process of safety-critical aviation systems. The research focuses on three innovative ideas to support this objective. First, probabilistic techniques will be introduced to specify system-level requirements and bound the performance of dynamical components.

Abstract:
Advances in power semiconductor devices have rapidly paved the way for high-frequency power electronics to the point that high-frequency distributed power systems (HFDPSs) - such as Boolean Microgrid - are increasingly becoming a practical reality, provided the effects of transmission-line length can be mitigated. However, the usage of HFDPSs has been primarily limited to the printed-circuit-board (PCB) level applications because of the transmission-line effect that a power signal encounters as it propagates through the transmission line .

Abstract:
GRID 2020: The power grid in the U.S. and many regions of the world is undergoing changes because of new technologies and government mandates. It is believed that smart meters and a smarter grid will lead to more efficient use of our infrastructure. In addition, increased renewable energy integration will provide power at low cost.
