The goal of this project is to study the loading capabilities of an inverter operating in grid forming mode. A Battery Energy Storage System (BESS) may need to power up a microgrid after an outage, thus supplying all of the magnetizing currents to line-start machines as well as isolation transformers in the microgrid. There is a need to understand the capabilities of the state-of-the art BESS inverters to support all of these loads. Though simulating such behavior is feasible, experimental validation is required to guarantee that the system will operate as expected, and the BESS inverter protection will not trip.

The emergence of quantum computers poses a serious threat for existing cryptographic systems and necessitates deploying new encryption schemes relying on different mathematical principles to protect electronic devices in the post-quantum era of computing. While theoretical security of these systems are being thoroughly analyzed, attacks on their practical implementations are largely unexplored. The primary research goal of this project is to develop secure implementations for lattice-based cryptosystems—a major class of post-quantum encryption proposals. This work specifically addresses power and electromagnetic side-channel vulnerabilities on physical implementations of lattice-based cryptosystems that can extract secret information by observing its correlation to these computation effects.
To advance the understanding of secure lattice-based cryptosystem implementations, this project proposes a framework that uses instruction set extensions (ISEs) that is designed to mitigate power and EM side-channels and integrated into a customized processor which can map security-critical computations to the ISE. As a result, lattice encryption software can be composed from a set of secure hardware operations and the proposed framework can therefore be automated to secure and benchmark different lattice-based post-quantum proposals. The project will disseminate publications, open-source hardware and software, and it is targeted to bridge the computer architecture and hardware security research communities. This work will also help the ongoing post-quantum standardization effort in US.

Many well-established problems in data science, such as data classification and clustering, raise unprecedented challenges in presence of complex and high dimensional data. Our interest is in inference applications, and more generally analysis problems, which in turn often resort to representation theory. Our goal is to build on the many previous and more recent accomplishments in Machine Learning and data science to develop the tradeoff of structure versus deep scale when representing data for either feature characterization and exploitation or inference applications. The vast array of applications in data science we typically encounter, and of interest herein, invariably seek to glean/use an extensive number of features of the data, which may also invoke the scale information whose necessary depth, as in deep learning (DL), remains an open problem We propose to develop an analytical framework for deep structure understanding using the existing Deep Leaning development as a source of inspiration. We proposed to investigate the tradeoffs of structure versus depth, noted above , as well as the known and open challenges of DL, such as Universal Approximation Property, and convergence issues. We expect our resulting algorithmic development to hence present great advantages in relation to the state of the art, with equal or better performance, with predictable behavior.

The proposed concept entails the research, development, and demonstration of an economical, data-fused grid edge processor (EDGEPRO) that can generate required data to support flexible grid operations by processing raw data from various existing sources (e.g., smart transformers, smart pole-top sensors, distribution automation (DA) controllers, smart inverters). The edge device will process high-speed and high-volume data by leveraging data fusion and machine learning (ML) technologies, making and executing local grid control decisions, and communica-ting certain processed data with other control systems, the cloud, and/or the utility control center. Because of its capabilities, the EDGEPRO will be able to calculate “virtual meter” data that, will eliminateing the need for installing additional grid monitoring sensors and devices at many feeder locations such as a service transformer, to and reduce the overall cost of flexible grid control. The target cost for the advanced edge data processor is $3000 USD per unit.

North Carolina State University (NCSU), ABB, and New York Power Authority (NYPA) will develop and demonstrate an intelligent, medium voltage (MV) extreme fast charger with integrated generation and storage capabilities that will help avoid negative impacts of extreme fast charging on the nation’s electric grid. The charger will be capable of delivering a combined 1 MVA to five vehicles, while enabling a charge rate of up to 350 kW per stall. The system will consist of a solid-state transformer (SST), which connects directly to the medium voltage (MV) and delivers power to a shared, 1,000 V DC bus, to which multiple vehicles, generation (PV), and storage units can be connected through partial-power DC/DC converters. The DC bus will be protected using novel intelligent solid-state circuit breakers, developed by ABB for this effort. Each vehicle will interface to the DC bus through a correctly sized DC/DC converter, allowing charging in the 50 kW to 350 kW range at the vehicle battery voltage. Therefore, this station will be capable of supporting state-of-the-art electric vehicles as well as the next generation of vehicles operating at higher voltages and faster charging rates.

The use of Radio Controlled (RC) Unmanned Aerial Vehicles (UAVs) or Drones, for civilian and commercial purposes have been growing steadily for the past decade. Their non-military use range from responding to Hurricane Harvey to rescuing swimmers caught in 10-ft swells, and from pizza delivery to Prime Air, the Amazon drone delivery system. UAV’s have historically had a limited flight radius dictated by line-of-sight radio controllers; however, distance limitation from which the drone operator can control them can be bypassed by using commercial wireless networks to control the drone. It is expected that billions of 5G mobile and Internet-of-Things (IoT) wireless devices will be all connected with the new millimeter wave frequency bands. We propose to analyze and validate the hypotheses that 1) using mmWave with antennas tilted upward for RF coverage in the sky can lead to a secure and reliable wireless network for UAV/Drone operation, 2) there is a unique opportunity to use NOMA (Non Orthogonal Multiple Access) with the primary mmWave beam aimed towards a swarm of Drones to control them with high security and efficiency, 3) further increase security, reliability, and spectral efficiency by using co-operative communications among the swarm of Drones and 4) this swarm of drones can be effectively used for emergency recovery of critical infrastructure such as a cyber compromised power grid that requires a black restart.

This collaborative work between the research teams of North Carolina State University (NCSU) and University of Washington (UW) aims to build a dynamic elastography imaging system for soft tissue. The imaging system developed by the UW Team has demonstrated the feasibility of a non-contact dynamic elastography imaging of the cornea. The system has mainly two components. An ultrasonic transducer that generates a focused beam to excite the soft tissue (micro-tapping) and an optical coherence tomography unit that captures the mechanical waves generated in the tissue. The work in this project covers the fabrication and system integration of the ultrasonic transducer arrays. The target prototype will have a precise transmit focus control on the surface of the soft tissue and create lateral beam oscillations for shear wave imaging.

The objective of this research will be on improving dynamic performance of New York State (NYS) power grid using supplementary Wide-Area Damping Control (WADC) with shunt-connected FACTS devices and Wind farms as the control actuators. The NY state is moving towards more renewable generation. The state of New York already undertaken a comprehensive energy strategy, known as Reforming Energy Vision (REV), for building a clean, more resilient, and affordable energy system. One of the major goals of REV is to reach 50% renewable generation by the year 2030. Bulk wind power integration will be a major contributor in reaching this goal. Different research conducted by New York Power Authority (NYPA) and FREEDM Systems Center have shown that high wind penetration can impact the grid oscillation properties adversely and can induce poorly damped inter-area oscillatory modes. This could result in destabilization of the power grid. In wake of this scenario, NYPA is considering to implement Wide Area Controllers within their territory. NYPA has already installed multiple Phasor Measurement Units (PMUs) all across the grid. Currently, data stream from PMUs is being used to provide Wide-Area Situational Awareness (WASA) for the system operators; however, this data is not being used for any decision making and control-based remedial action for grid operation. Recently more emphasis is given to use this Wide-Area Measurement Systems (WAMS) in order to design oscillation damping controllers. This research will look into explore the feasibility, constraints and possible solutions for the real-life implementation of wide-area damping controllers through FACTS and Wind farms in New York State Grid.
