“…The AMI system primarily communicates through smart meters usually installed in consumer connections, and it has a hierarchical structure composed of a DCU, which collects information, and a meter data management system (MDMS), which oversees the overall consolidation and management of gathered information [30][31][32]. Improving on the existing method of limiting communications between the smart meter and the DCU to one technology, a hybrid AMI environment is a system comprised of either a mixed method that uses multiple communications in a complementary fashion or a combined method that dualizes multiple communications, depending on the environment.…”

Advanced metering infrastructure (AMI) refers to the electricity service infrastructure between electricity consumers and suppliers and is technically essential for the realization of a smart grid environment. To implement AMI, various communications technologies are being used based on the application environment according to the utility. However, using a single communications method can give rise to attenuation in the downtown underground distribution line section or cause higher supply costs due to decreased density in the range from farming to fishing areas. A hybrid AMI is one solution to this problem. According to an economic analysis of previous AMI deployment, the cost to install a communications network accounts on average for 45% of the total cost. Since the installation cost of a communications network is influenced by the density of the installation environment, a hybrid AMI, which allows the configuration of a flexible network using both wired and wireless communications, can be a good alternative, both technically and financially. This study conducted a simulation based on density of the installation environment and configuration of the communications network to analyze the economic effect of installing a hybrid AMI communications network. It assumed that a hybrid AMI was deployed in an overhead distribution line in a low-density area. The simulation outcomes were compared and analyzed against the power line communication (PLC)-only AMI method. The results showed that the hybrid AMI method had a 10% communications network cost reduction effect compared to the PLC-only AMI method. In addition, the analysis indicated that there was a maximum 19% cost reduction effect in communications network installation depending on the method of network installation, suggesting that the hybrid AMI was economically more effective than the PLC-only AMI method.

Diseño y evaluación del desempeño de una red de comunicaciones para medición inteligente en Network Simulator-2Design and performance evaluation of a communication network for smart metering in Network Simulator-2 ResumenEste artículo presenta los resultados de diseño y evaluación del desempeño de una red de comunicaciones para medición inteligente o AMI (Advanced Metering Infrastructure), empleando el simulador de redes Network Simulator-2 (NS-2). La red de comunicaciones propuesta combina las tecnologías PLC (Power Line Communication) y HSDPA (High Speed Downlin Packet Access), así como el uso de concentradores de datos (DC) y de protocolos aplicación y transporte como DLMS/COSEM y TCP-UDP/IP. Los resultados de evaluación indicaron que al introducir dispositivos DC dentro del diseño de red de comunicaciones,ésta presenta un desempeño superior frente a otras que no los emplean para concentrar la información de diferentes medidores inteligentes. Finalmente, se observó una mayor cobertura y un menor número de acceso directos a la red de comunicaciones al considerar DC en el diseño.Palabras claves: AMI, comunicaciones móviles 3G, DLMS/COSEM, PLC, redes inteligentes. AbstractThis article presents the results of design and performance evaluation of a Smart Metering or AMI network, using the Network Simulator-2. The communication network proposed combines technologies such as, PLC and HSPDA, using data concentrators (DCs) and application and transport protocols such as DLMS/COSEM and TCP/IP. The performance evaluation results shown that introducing data concentrator inside a communication network provides a superior performance compared with others that not use it. Finally, the employment of DCs on the design also extended communication coverage and reduce direct accesses to the network.

“…The Smart Grid, rolled out by the National Institute of Standards and Technology (NIST) [1], is a next generation power system which allows consumers and electric utilities to communicate interactively. Compared with legacy power systems, the Smart Grid has new energy management capabilities, such as an advanced metering infrastructure (AMI) [2] and a demand response [3]. AMI is an architecture for automated, twoway communication between a consumer with an IP address and an electric utility.…”

A use of an electric outlet by a consumer forces the outlet manager to pay for the consumer's power usage in current electrical power systems. Even if a consumer uses an outlet managed by another person, one bill for both indoor and outdoor charging information should be required to the consumer in their contract with the utility company. For this purpose, we define a model for the Smart Grid security and propose a Secure Payment Protocol for Charging Information over Smart grid, SPaCIS for short, as a protocol satisfying the model. Our model provides for the unlinkability of consumers as well as for the undeniability and unforgeability of billing information using digital signatures and identity federations. SPaCIS is also efficient in the sense that time complexity is constant relatively to a trivial use such as an individual verification for each signatures, unless a verification error happens. We furthermore evaluate performance of SPaCIS via cryptographic implementation, and simulate SPaCIS in a case that one thousand users generate thirty signatures. Then, we show that SPaCIS with ECDSA can be executed within 6.30 msec for signing and 21.04 msec for verification of signatures, and conclude that SPaCIS is fairly practical.
