Smart grids, or intelligent electricity grids that utilize modern IT/communication/control technologies, become a global trend nowadays. Forecasting of future grid load (electricity usage) is an important task to provide intelligence to the smart gird. Accurate forecasting will enable a utility provider to plan the resources and also to take control actions to balance the supply and the demand ...

With the capacity of achieving spectrum efficient wireless communications, cognitive radio enabled Advanced Metering Infrastructure (CR-AMI) networks are expected to enhance the efficiency and practicability of future smart grids. CR-AMI networks which has been recognized as a fundamental component of the smart grid ecosystem, are practically utilized as a static multi-hop wireless mesh network...

Given rising electricity consumption, coupled with finite resources, ICT-enabled electrical networks such as smart grids are increasingly being deployed by energy companies. One part of smart grids is smart meter technology (SMT), which are digital electrical meters, having the potential to increase energy efficiency in both residential and industrial sectors. However, a challenge to SMT-implem...

Smart Grid technology appears necessary to succeed in activating the demand through demand side management (DSM) programs. This would in turn improve energy efficiency and achieve environmental targets through controlled consumption. The many pilot projects led worldwide involving smart grids technology, brought quantitative evaluations of DSM measures on electricity load. Efficient DSM instrum...

The paper discusses power and especially voltage quality issues in the smart grid environment. New demands that are facing the distribution network, by introducing the concept of intelligent networks (Smart Grids), are presented. Some examples of non-compliance of laws and practices in Serbia are presented as well, as the illustration of lack of strategic planning in the field. Through several ...

New intelligent power grids (smart grids) will be an essential way of improving efficiency in power supply and power consumption, facilitating the use of distributed and renewable resources on the supply side and providing consumers with a range of tailored services on the consumption side. The delivery of efficiencies and advanced services in a smart grid will require both a comprehensive over...

Power line carrier (PLC) technology plays an increasingly important role in the realization of cost-effective communication in a smart distribution grid. No current channel modeling method is universally applicable to more complex topologies that may emerge in smart grids, such as ring and mesh topologies. This paper presents a novel PLC channel modeling method based on the information node con...

Next generation of smart grids face a number of challenges including co-generation from intermittent renewable power sources, a shift away from monolithic control due to increased market deregulation, and robust operation in the face of disasters. Such heterogeneous nature and high operational readiness requirement of smart grids necessitates decentralized control for critical tasks such as pow...

We propose to simulate the Information Systems of Smart Grids to validate / criticize the modeling choices of domain experts. We propose a viewpoint based approach regarding two aspects : information and dynamics. We add an integration viewpoint to maintain consistency and we use Model Driven Engineering techniques. Finally, we experience our approach on a Smart Grid use case. MOTS-CLÉS : Simul...

The current uncertainty about oil and gas prices and their resources, and future energy concerns, smart grids lead to further development. In this paper, a two way communication-based distributed control for voltage regulation in smart grid is proposed. Moreover, 16-bus distribution feeders system is modeled by real time simulation in MATLAB/Simulink in order to evaluate the effectiveness of th...
