  4. TCIPG Technical Clusters and Threads

  5. Smart-Grid-Enabled Distributed Voltage Support Objectives • Develop an authenticated framework for mobilizing distribution-level devices to provide reactive support. • Facilitate near real-time reactive control at residential level. • Validate simulated control algorithms in a laboratory setting with actual power system devices. Recent Achievements • A framework and algorithm to coordinate reactive load control were developed and the researchers are building an inverter-battery device that will be capable of providing reactive power support. • The researchers are working to implement the ideas presented in the papers for application on the University of Illinois campus distribution system. • The algorithms can then be used to dispatch this device. A paper was accepted for publication in the IEEE Transactions on Smart Grid.

  6. Specification-based IDS for AMI Objectives • Design an efficient monitoring architecture to detect and potentially prevent intrusions targeting or originating from an AMI. • Implement a prototype of this monitoring solution and validate its accuracy and applicability. Recent Achievements • Presented a paper about the project at IEEE SmartGridComm2010. • Developed a working prototype of a network sensor in Python. • Tested the prototype with an emulated AMI using Trilliant Table Testbench. • Designed and implemented a visualization console, and demonstrated the monitoring architecture during the annual TCIPG workshop. • Established a connection with Robert Former from Itron to test the prototype on real hardware meters.

  7. Non-Intrusive Load Monitoring Objectives • To develop more effective techniques to safeguard privacy in the face of expanding data collection. • To utilize existing meter technologies to track the characteristics of home appliances and verify energy-saving measures. Approach/Research Plan Recent Achievements • Develop load signal masking techniques to thwart invasions of privacy with minimal distortion of the signal. • Develop more accurate load models of specific appliances by observing characteristics over time. • Recently developed a Hidden Markov Model toolkit that will facilitate the analysis of data that have been collected from various residences. This method is showing improvement over the clustering methods that were previously attempted.

  8. V2G Cyber Security Objectives • To show that the cyber security protection of the V2G communication layer can be cast into a form so that the Least Privilege Architecture (LPA) provides an appropriate structure to protect the cyber security of the grid. • To adapt LPA to specific needs of V2Gproblem. • To demonstrate the ability of the adapted LPA to operate effectively in the V2Gframework. Recent Achievements • LPA provides mechanisms to effectively limit the privileges of each service so that it can only access the functions it needs to fully complete its tasks. • LPA provides restricted access to the database to each service at a level commensurate with the requirements to complete the service tasks. • LPA facilitates the decomposition of the Aggregator’s functions into logically disjoint services, leading to enhanced security. • LPA minimizes the impact of a successful attack on a single service. • LPA allows room to expand services to third-party vendors. • LPA facilitates the easy expansion of the number of BVs and parking lots in the aggregation.

Computer B Recent Achievements • A framework and algorithm to coordinate reactive load control were developed. • The algorithm is based on a layered architecture that would follow a chain of command from the top layer (transmission grid) to the bottom layer (distribution grid). • A reactive load control optimization algorithm to improve the voltage profile in the distribution grid was developed. The entire framework integrates agent-based technologies to manage the data and control actions required to operate this type of architecture in both of the power networks. • A paper was accepted for publication in the IEEE Transactions on Smart Grid.

  10. Quantifying the Impacts on Reliability of Coupling between Cyber and Physical Components Objectives • Construct models to analyze the impact of PMU misbehavior: • GPS spoofing affects the synchronization of PMUs. • Filtering algorithm implementation affects the quality of the phasormeasurement. • Data transmission limitations and communication failures affect continuous measurement availability. GPS Spoofer PMU Recent Achievements • Formulation of maximum achievable GPS time-synchronization error. • Development of MATLAB code for maximizing GPS time-synchronization error under constraints. • Satellite provides time synchronization for PMUs. • GPS spoofer overpowers satellite signal and provides the wrong time-synchronization information to the PMU.

  11. TCIPG Testbed • Goals and Approach • Provision for experimental support and integration of TCIPG projects • Serve as national resource for experimental work in analysis of power grid system resiliency • A Simulation and emulation environment with real hardware and software used in the power grid • Span Transmission, Distribution & Metering, Distributed Generation and Home Automation and Control • FY 11 Plans • Mid-term • Develop new modeling and evaluation technologies to enhance evaluation capabilities of the testbed • Develop integration glue to further link new components into the testbed • Short-term • Expand testbed through software and hardware augmentation to flush out the defined modules (Transmission, Distribution, Home Area Monitoring and Control, and Distributed Generation) • Senior researchers: David Nicol, Bill Sanders, Tim Yardley

  12. Testbed • Achievements • Continued involvement in Deter Enabled Federated Testbeds (DEFT) Consortium • Progress made on bringing in new software and hardware to support our growing TCIPG research needs • Remote access to the TCIPG testbed is available now • Testbed related staffing proceeding well • Publications • Extended open-source CORE emulation engine to support virtual time [ZhengN1] • Investigated susceptibility of data aggregators to buffer flooding attacks [JinNY1]

  13. Education and Engagement Project Objectives • Link researchers, educators, consumers, and students. • Develop pedagogically and technologically sound curriculum materials relating math and science to power, energy, and cyber communication issues and utilize these materials to connect with middle and high school teachers and students. • Create interest in STEM disciplines and careers. • Illustrate issues necessary for consumer acceptance and use of smart grid technologies. Advanced metering technologies allow two-way communication between the utility and the consumer. tcipg.mste.illinois.edu
