Smart Grid es un nuevo concepto que busca articular los sistemas de energía eléctrica y de comunicaciones como un sistema unificado para la optimización del consumo energético en el mundo, en donde una de las tecnologías más aceptadas para la transmisión de información en entornos residenciales es Power Line Coomunicatios (PLC). El objetivo del presente artículo consiste en proponer un modelo soportado en teoría de colas, que permita evaluar el comportamiento del tráfico multiclase una red HAN (Home Area Network) bajo el estándar HomePlug AV (HPAV), el cual es uno de los estándares más importantes de la tecnología PLC. Acorde con los resultados obtenidos, el modelo propuesto permite estimar parámetros tales como tiempos de llegada, tiempos de espera en cola, tiempos de atención, probabilidad de pérdida de paquetes, throughput, número de paquetes perdidos, entre otros valores relacionados con el rendimiento de la red. Aunque el modelo puede ser considerado de gran ayuda para trabajos de investigación relacionados con las comunicaciones sobre PLC, podría ser combinado con otras técnicas de análisis más avanzadas, a fin de obtener resultados más profundos y en contextos más complejos.

Securing the network communication for the smart grid, it is important that a secure key distribution and management scheme is needed. Advanced metering Infrastructure (AMI) is considered as integral part of the smart grid that collects and analyzes the information of energy consumption using the communication network. In order to achieve data confidentiality, privacy, and authentication in AMI, various crypto algorithms are used, such as demand key distribution and management schemes. Investigation on properly designed key distribution and management scheme for securely gathering both individual and aggregated meter’s readings is one of the critical requirements. In this paper, we propose a secure key distribution for Home Area Network (HAN) in smart grid. In this paper, we propose a new key distribution and management scheme, which uses identification scheme of Wu – Hsu and tailored to smart grid. We also give the scheme for key update/freshness and key revocation. Specifically, a group ID based mechanism is proposed to establish the keys for a large amount of users with small overload.

This paper discusses aims, architecture, and security issues of Smart Grid, taking care of the lesson learned at University of Pisa in research projects on smart energy and grid. A key element of Smart Grid is the energy home area network (HAN), for which an implementation is proposed, dealing with its security aspects and showing some solutions for realizing a wireless network based on ZigBee. Possible hardware-software architectures and implementations using COTS (Commercial Off The Shelf) components are presented for key building blocks of the energy HAN such as smart power meters and plugs and a home smart information box providing energy management policy and supporting user's energy awareness.

Home Area Networks can be implemented via both wired and wireless solutions. Smart meter performs power or electricity metering and has the capability of transferring key meter data via wired and wireless sensors. The proposed solution provides a seamless connectivity between ZigBee and Power Line Communication networks to reap benefits from their respective advantages. Since these two technologies are complementary media, the combination is more suitable for smart meter to meet different requirements.
