In this project, we will develop high temperature (> 600 C) embedded/integrated sensors (HiTEIS) for wireless monitoring of reactor and fuel cycle systems. HT pressure sensors, vibration sensors and liquid level sensors will be designed, fabricated, embedded and characterized, followed by nuclear structure integration and evaluations. The proposed technique will likely be used to enhance the safety and efficiency of nuclear power systems.

To enhance the microgrid’s scalability, reliability, and resilience, this project aims to develop a collaborative and distributed energy management system (CoDEMS) that can determine globally optimal control commands without the need for a central coordinator. This phase of the project will develop a 2-node system that can provide an optimal charging and discharging schedule of the energy storage system using information from the grid support point and load forecast.

This Accelerating Innovation Technology Translation project focuses on translating a novel Smart Battery Gauge technology to meet the increasing need for accurate battery charge level and remaining life estimations for stationary energy storage systems of renewable energy. This global battery market is currently $89B and is expected to reach $132B by 2016. Specifically, propelled by the US renewable portfolio standards (RPS) targets (20% renewables in 2025) and the President‘s clean energy goals (80% in 2050) to improve the efficiency of power grid and reduce greenhouse gas emissions, the large-scale integration of renewable energy into the power grid is driving great demand in stationary battery energy storage systems. However, the reliability and safety concern remains as the major barrier that prevents its widespread deployment, which not only may cause unplanned system downtime, but also leads to high battery maintenance cost. The Smart Battery Gauge technology is proposed to improve the reliability and safety of energy storage systems. It outperforms the existing solutions with three salient features: 1) Accurate battery state of charge (SOC) estimation using the adaptive battery model parameters, 2) Accurate battery remaining useful life (RUL) estimation using adaptive model predictive approach, and 3) Flexible customizations for different battery chemistries. To demonstrate commercial potential of the proposed Smart Battery Gauge technology, it will be essential for us to prototype our technology and show that it is feasible to be used in stationary energy storage systems. To achieve this goal, we propose to: 1) Validate the battery SOC estimation accuracy by implementing the patent-pending co-estimation algorithm in an ARM microcontroller, and compare it with off-the-shelf products; 2) Extract the relevant data and models that are needed for battery RUL estimation; 3) Design adaptive algorithms to adjust the parameters of the battery, power generation/ consumption, capacity degradation, and internal resistance escalation models with real-time measurement feedback; 4) Implement the adaptive model predictive algorithm in the ARM microcontroller and compare the RUL estimation results with existing literature approaches and off-the-shelf products. The expected outcome of this project is prototyping the Smart Battery Gauge technology with 95% accuracy in SOC estimation and 10 days accuracy in RUL prediction.

The penetration of energy storage into the grid is low due to the inability to accurately and constantly assess the State of Charge (SOC) and State of Health (SOH). The Smart Battery Gauge can constantly monitor the batteries to provide live and accurate updates about the battery’s status to alleviate these issues

The objective of this proposal is to formulate a novel methodology for creating secure algorithms in cyber-physical systems and to develop metrics for evaluating the security of composed systems. Cyber-physical systems are composed of interconnected, semi-autonomous devices. The inherently open nature of a CPS implies a susceptibility to attacks that differ fundamentally from conventional cyber attacks. CPS-specific attack vectors exist as purely cyber, cyber-enabled physical attacks, and physically enabled cyber attacks. As such, the endpoints may be fundamentally unsecurable (such as the sensed information from physical resources) or may be compromised (as in computational resources). Creating a secure communications channel between two nodes is inadequate if one of the endpoints of the communication is insecure. Therefore, new methodologies are needed to ensure that the system is protected in the presence of open information flows from physical resources and possibly malicious entities inside the system.

Our vision for the ERC for Future Renewable Electric Energy Delivery and Management (FREEDM) Systems is an efficient electric power grid integrating highly distributed and scalable alternative generating sources and storage with existing power systems to facilitate a green energy based society, mitigate the growing energy crisis, and reduce the impact of carbon emissions on the environment. We believe the key to solving the energy crisis is not necessarily the renewable energy itself, but the infrastructure needed to deliver and manage large scale distributed renewable energy resources (DRER). The mission of the ERC for FREEDM Systems is to develop the fundamental and enabling technology to demonstrate the system and, through such development and demonstration, foster a revolution in innovation and technology in the electric power and renewable energy industries, providing long-term energy security and environmental sustainability for the U.S. Key Goals: - Develop the fundamental knowledge base for the FREEDM system and provide fundamental breakthrough technology in energy storage and power semiconductor devices. - Develop enabling technologies for subsystem and system demonstrations. - Develop a 1MW FREEDM system to demonstrate the green energy hub concept. - Develop a diverse group of adaptive, creative, and innovative graduates who advance fundamental knowledge, enabling technology and engineered systems innovations in renewable electric energy delivery and management systems - Develop long-term partnerships with middle and high schools, teachers, and students to enhance engineering content knowledge and pedagogical methods, bring engineering concepts into the classroom, involve pre-college students in research, and thereby increase the diversity and enrollment of domestic students in university engineering degree programs. - Form long-term partnerships with large and small firms to speed the translation of ERC research into commercially viable products, stimulate formation of start-up companies based on ERC intellectual property, and involve students in all phases of the innovation process. - Increase the diversity of the proposed Center?s leadership, faculty, and students to exceed academic engineering-wide national averages within the first five years of operation. Intellectual Merit: In addition to social, economic, and market challenges to be addressed by the ERC and by the power industry as a whole, barriers include needs for: new system theory for the paradigm-shifting FREEDM system; new high-frequency high-voltage power electronics based on wide bandgap materials; significantly higher energy density storage technologies. Innovative development of such an infrastructure cannot be expected to occur in today?s centralized model, where power companies seek only incremental solutions and research investments are suppressed to maximize profits. A systems approach required cannot be expected to occur through individual research projects with no common standards or test bed. To develop the FREEDM system, a multidisciplinary center of excellence is needed to pull together our nation?s top expertise in energy system theory, policy, renewable energy technology, energy storage technology, electronic devices, and communication. Broader Impacts include an increasingly diverse and innovative pool of U.S. engineers; mitigation of global warming; aversion of an energy crisis; innovation in renewable energy systems developed with industry leading to new products, companies, and jobs; integration of innovation in multidisciplinary training for graduate and undergraduate students; broadening participation in power engineering through integrated research activities for K-12 teachers and students; and improved faculty and graduate student skills in mentoring minorities and women.
