Requirements Based Evaluation of BPL for Power System Sensing, Command and Control Applications Erich W. Gunther EnerNex Corporation

CEIDS Mission Mission To develop the science and technology that will fundamentally transform the infrastructure to cost- effectively provide secure, high-quality, reliable electricity products and services

Integrated Energy and Communications System Architecture (IECSA) IECSA is an open, standards-based systems architecture for the data communications networks and intelligent equipment necessary to support the power delivery infrastructure of the future.

IECSA Project Objectives Develop a complete set of systems requirements and architecture documents to support industry-wide enterprise architecture for a self-healing grid and integrated consumer communications interface. Contribute project results as appropriate to relevant standards development organizations and industry consortia to effectively move the development of key open standards forward to develop a robust industry infrastructure. Apply systems engineering to the development of the architecture including but not limited to: the elicitation and management of system requirements, analysis of requirements and development of proposed architectural designs, evaluation of architectural designs and the use of standardized industry notation for documentation of architectural views. Identify the potential for infrastructure sharing and synergy between power engineering operations and other application domains.

Self Healing Grid Objectives and Functions

Approaches to Technology Development Develop a technology, find uses for it Identify a problem, select or develop a technology to solve it Identify domain requirements, select, develop or improve technologies that address the requirements

FCC Goals The FCC wants to leverage broadband power line technology to: 1.improve the competitiveness of the broadband service market; 2.increase the availability of broadband services in underserved areas; 3.encourage the uses of these advanced technologies to improve safety and efficiency of power distribution by adding intelligent networking capabilities to the electric grid

Power Distribution Applications Cinergy: BPL technology can enable a variety of power distribution applications, including: –Automated outage detection and restoration confirmation –Remote monitoring and operation of switches and transformers –Remote capability to connect and disconnect electric service –Demand-side management programs –Automated meter reading

Distribution System of the Future

Consumer Portal

Communication Technologies for the IECSA Wired Networks –PSTN POTS –Leased Lines (X.25, T1, other) –Fiber Networks (ATM/SONET/Gigabit Ethernet) –Broadband DSL –Broadband Cable –Broadband Power Line Wireless Networks –Microwave –Serial radios (FreeWave, Locus) –WiFi / WiMax –Cellular –2 Way Pager

Key Communications System Attributes Bandwidth Latency Determinism Immunity (environment) Access Control (physical, identification, authentication) Confidentiality (encryption) Integrity (identification of bad data) Availability (inherent component reliability and DOS issues) Privacy (traffic analysis, information leakage)

Selected BPL Issues Interference with other services (emissions) Interference from other services (immunity) Impact of power system topology on BPL performance –Capacitor banks – switched and fixed –Automatic circuit reconfiguration –Micro grids - islanding
