  • ICCCN - SCAPACH: Scalable Password-Changing Protocol for Smart Grid Device Authentication
    2013 22nd International Conference on Computer Communication and Networks (ICCCN), 2013
    Co-Authors: Rehana Tabassum, Klara Nahrstedt, Edmond J. Rogers
    Abstract:

    In Smart Grid, the scale of pole Devices that monitor the health of power line is very large. Moreover, with the upgrade of Smart Grid, the number of these resource-constrained (in terms of memory and computation) Devices is further increasing. These Devices are easy targets to security attacks as they are accessible via wireless network, and use weak passwords for authentication and transferring telemetric data to the pole maintenance personnel. In this paper, we present a SCalable and Automated PAssword- CHanging protocol, SCAPACH, for unique authentication of human personnel (operator) and secure collection of telemetric data from a large number of pole Devices. SCAPACH employs physical per- operator, per-pole-Device information as well as changeable secret salts to generate new unique passwords and secret keys every time a pole Device is accessed. Our experiments confirm that the password-changing protocol authenticates and transmits pole Device data securely and in real-time under varying maintenance scenarios.

  • Validation and Simulation for High-Penetration Photovoltaic Deployment in the Arizona Public Service System
    2020
    Co-Authors: Murali Baggu, I Raja Ayyanar, David Narang
    Abstract:

    In an effort to better understand the impacts of high penetrations of photovoltaic (PV) generators on distribution systems, Arizona Public Service and its partners are implementin g a multi-year project to develop the tools and knowled ge base needed to safely and reliably inte grate hi gh penetrations of utility- and residential-scal e PV. Buildin g on the APS Community Power Project-Fla gstaff Pilot, this project investi gates the impact of PV on a representative feeder in northeast Flagstaff. To quantify and catalo g the effects of the estimated 1.3 MW of PV that will be installed on the feeder (both smaller units at homes, as well as lar ge, centrally located systems), high-speed weather and electrical data acquisition systems and digital "Smart" meters were desig ned and installed to facilitate monitorin g and to build and validate comprehensive, high-resolution models of the distribution system. These models are bein g developed to analyze the impacts of PV on distribution circuit-protecti on systems (includin g coordination and anti­ islandin g), predict volta ge regulation and phase-balance issues, and develop voltlVAr control schemes. This paper expands upon a paper presented at the 2013 IEEE PVSC conference that described updated results from the data acquisition effort, newly developed graphical analysis tools, continued feeder modelin g, utility-scale PV inte gration and performance, and continued model validation. This paper presents results from Phases 3 and 4 of the project. Specifically, the paper discusses feeder model evaluation and extended application for advanced scenario analysis, specifically feeder reconfi guration, Smart- Grid Device interaction study, Smart inverter Grid, and support functionality.

  • A Secure and Efficient Framework to Read Isolated Smart Grid Devices
    IEEE Transactions on Smart Grid, 2017
    Co-Authors: Ke-wei Sha, Naif Alatrash, Zhiwei Wang
    Abstract:

    With increasing deployments of Smart Grid systems, a large quantity of energy usage and Grid status data have been collected by Smart Grid Devices like Smart meters. To secure these critical and sensitive data, it is crucial to prevent unauthorized readings from these Devices. Many authentication protocols have been proposed to control access to Smart Grid Devices that are a part of the Smart Grid data communication network; however, authentication protocols to control readings from the isolated Smart Grid Devices are mostly ignored. In this paper, we propose a secure and efficient framework to enable secure data readings from the isolated Smart Grid Devices based on a two-phase authentication protocol. The framework not only makes use of the Smart reader as a bridge to connect the isolated Smart Grid Device and the Smart Grid cloud, but also considers the physical constraints of all the Devices in the system. Security analysis shows that our framework is efficient and secure under most typical attacks, meanwhile it satisfies the hardware constraints of Smart Grid Devices. Comprehensive performance evaluation also validates the efficiency of the proposed framework.
