The integration of information and communication technologies in power networks enables greater flexibility through Smart Grids and increased network adequacy and reliability. Information and communication technology's functionality and design diversity within the cyber-physical power system should be explicitly defined to quantify the risk of information and communication technology failures. The purpose of this paper is to quantify the cyber-physical reliability risk introduced by the information and communication technology deployed for dynamic line rating implementations, which are usually installed in adverse environments and have a higher failure risk than indoor information and communication technology installations. This cyber-physical reliability study employs a modified sequential Monte Carlo approach with a Markov state space to capture the dynamic line rating-information and communication technology functionality. The method integrates the additional dynamic line rating states within the overhead line operating states, which allows quantifying the risk of dynamic line rating failures against the risk of traditional probabilistic line rating uprating practices. Results from IEEE 24-bus and 14-bus network reliability studies indicate that dynamic line rating-information and communication technology failures (a) increase generation costs in the 24-bus transmission network with high generation flexibility, while (b) they reduce the reliability of the 14-bus network with small generation diversity and multiple load points. Such results can provide insightful recommendations on the quality of dynamic line rating-information and communication technology infrastructure and inform utility's investment planning processes and maintenance practices. INTRODUCTION AND BACKGROUNDSmart Grids have emerged intending to improve power network flexibility, efficiency, reliability, and security through the economic integration of real-time advanced sensing, communication and control functionalities [1,2]. The advantages of Smart Grids originate from information and communication technologies (ICT) implementation to provide system operators with increasing network visibility despite contingencies and other uncertainties, thereby allowing for additional remedial preventative and corrective actions [3][4][5][6].

Abstract-Indian power sector is growing at an enormous pace. Building and operating such a power system is a challenging problem. The power network which carries the MWs across large distances is analogous to a "muscle system" of human body. Likewise, the entire range of associated monitoring and control network is analogous to a "nervous system". While strengthening the muscles is important in order to fully realize the potential, they also have to be complemented by an intelligent nervous system. This paper focuses on the intelligent grid aspects and the initiatives taken by the National Grid of India towards that direction. The participation of IBM -Indian Institute of Technology, Bombay (IITB) in the Intelligent Utility Network (IUN) research is also mentioned.
