The knowledge of distribution grid models, including topologies and line impedances, is essential for monitoring, control protection. However, such information often unavailable, incomplete or outdated. increasing deployment smart meters (SMs) provides a unique opportunity to tackle this issue. This paper proposes two-stage framework modeling using SM data. In the first stage, network topology ...

An optimization methodology for the combination of several green technologies is introduced in this paper. These are smart meters, smart appliances, solar power systems and time-of-use (TOU) pricing. These technologies are collectively and widely utilized in the recent smart grid, which is rolling out all over the world to facilitate greener power generation and distribution. Adaptive particle ...

The evolution of the World Wide Web and mobile devices has presently created a giant number of textual communications. The life of a modern person is now saturated with textual information and interactions such as SMS(s), e-mails, chats, social media texts and so on. Therefore the need continuously rises for smart input methods. Smart keyboards, enabled with next word prediction and auto comple...

The Short Message Service (SMS) have an important economic impact for end users and service providers. Spam is a serious universal problem that causes problems for almost all users. Several studies have been presented, including implementations of spam filters that prevent spam from reaching their destination. Naïve Bayesian algorithm is one of the most effective approaches used in filtering te...

Smart grids are susceptible to cyber-attack as a result of new communication, control and computation techniques employed in the grid. In this paper, we characterize and analyze the resiliency of smart grid communication architecture, specifically an RF mesh based architecture, under cyber attacks. We analyze the resiliency of the communication architecture by studying the performance of high-l...

The response time of the smart electrical vehicle (EV) charging infrastructure is the key index of the system performance. The traffic between the smart EV charging station and the control center dominates the response time of the smart charging stations. To accelerate the response of the smart EV charging station, there is a need for a technology that collects the information locally and relay...

Smart sensors are emerging as a promising technology for a large number of application domains. This paper presents a collection of requirements and guidelines that serve as a basis for a general smart sensor architecture to monitor electricity meters. It also presents an electricity meter monitoring network, named EMMNet, comprised of data collectors, data concentrators, hand-held devices, a c...

In this paper, by considering the constraints of Advanced Metering Infrastructure (AMI) systems, we propose an authenticated key exchange protocol and an authenticated message broadcasting protocol. The proposed protocols are based on two well-known protocols, Okamoto and Schnorr, and inherit their security features. For providing the security of the system against physical attacks, we utilize ...
