Distribution systems with advanced metering infrastructure offer many opportunities for fault detection. A novel approach is presented in this paper local diagnosis neighbour area networks by utilizing data concentrators. lightweight diagnostic function based on first engineering principles. It shown that from four phasor measurement unit data, a can be detected between buses and parameters eva...

In this paper, we investigate whether “big-data” is more valuable than “precise” data for the problem of energy disaggregation: the process of breaking down aggregate energy usage on a per-appliance basis. Existing techniques for disaggregation rely on energy metering at a resolution of 1 minute or higher, but most power meters today only provide a reading once per month, and at most once every...

Climate change, awareness of energy efficiency, new trends in electricity markets, the obsolescence of the actual electricity model, and the gradual conversion of consumers to prosumer profiles are the main agents of progressive change in electricity systems towards the Smart Grid paradigm. The introduction of multiple distributed generation and storage resources, with a strong involvement of r...

We have developed the first hardware and software (intellectual property) metering scheme that enables reliable low overhead proofs for the number of manufactured parts and copied programs. The key idea is to make each design slightly different during postprocessing phase. Therefore, if two identical hardware/software designs or a design that is not reported by the foundry are detected, the des...

Recent years have witnessed the exciting developments for power grid. For instance, many traditional mechanical components are being replaced by modern electronics devices that can operate intelligently; new elements, such as renewable energy resources and various large-scale storage, introduced into grid to bring a outlook on system operation control; smart appliances produced facilitate more ...

A System-Wide Adaptive Ramp Metering (SWARM) system has been implemented in the Portland, Oregon metropolitan area, replacing the previous pre-timed ramp-metering system that had been in operation since 1981. SWARM has been deployed on six major corridors and operates during the morning and afternoon peak hours. This paper reports on the results of a “before” and “after” evaluation of the perfo...

Advanced Metering Infrastructure (AMI) is the metering network of smart grid that enables bidirectional communications between each consumer’s premises and provider’s control center. The massive amount data collected supports real-time decision-making required for diverse applications. communication infrastructure relies on different types, including Internet. This makes vulnerable to various a...

P u b l i s h e d b y t h e I E E E C o m p u t e r S o c i e t y nizations might be tempted to inflate the number of registered accesses. Even a trusted host site can generate statistics that do not correspond to real usage. Several metering techniques attempt to accurately measure the number of visits a site receives and hence the advertising exposure, but advertisers and auditing companies h...

In a smart power grid, collecting data from a large number of smart meters and sensors over the conventional one-hop transmission control protocol (TCP) communication is prone to a high packet loss rate and degraded throughput due to the ineffectiveness of the TCP congestion control mechanism. The Split and Aggregated TCP (SA-TCP) proposes upgrading intermediate devices (known as regional colle...
