This paper investigates the effect of simultaneous placement of DGs and smart meters (SMs), on voltage profile improvement in active distribution networks (ADNs). A substantial center of attention has recently been on responsive loads initiated in power system problem studies such as distributed generations (DGs). Existence of responsive loads in active distribution networks (ADNs) would have u...

A smart grid based Advanced Metering Infrastructure (AMI), is a technology that enables the utilities to monitor and control the electricity consumption through a set of various smart meters (SMs) connected via a two way communication infrastructure. One of the key challenges for smart grids is how to connect a large number of devices. On the other hand, 4G Long Term Evolution (LTE), the latest...

The smart grid has been introduced as the next generation power grid. Advanced Metering Infrastructure (AMI) is one of the key components in this grid. It provides bidirectional communication between consumers and management entities in the utility side. This bidirectional nature communication flow has made AMI vulnerable to various cyber attacks. So, cyber security has become an important conc...

This paper deals with prepaid smart meters energy management system using ARDUINO microcontroller with labVIEW has been introduced. Smart meters are the key component of the smart grid which helps both the user and supplier to control consumption of energy according to availability of resources. The proposed energy metering system consists of smart meter, zigbee communication and mobile user. Z...

Smart meters (SMs) are being widely deployed by distribution utilities across the U.S. Despite their benefits in real-time monitoring. SMs suffer from certain data quality issues; specifically, unlike phasor measurement units (PMUs) that use GPS for synchronization, not perfectly synchronized. The asynchrony error can degrade monitoring accuracy networks. To address this challenge, we propose a...

The implementation of the smart grid (SG) and cyber-physical systems (CPS) greatly enhances safety, reliability, efficiency energy production distribution. Smart grids rely on meters (SMs) in converting power (PGs) a reliable way. However, proper operation these needs to protect them against attack attempts unauthorized entities. In this regard, key-management authentication mechanisms can play...

The presence of responsive loads in the promising active distribution networks (ADNs) would definitely affect the power system problems such as distributed generations (DGs) studies. Hence, an optimal procedure is proposed herein which takes into account the simultaneous placement of DGs and smart meters (SMs) in ADNs. SMs are taken into consideration for the sake of successful implementing of ...

Methods We used SMS to collect symptoms and peak flow (PEF) meter readings from children with asthma. Digital PEF meters enabled data download to confirm validity of PEF data sent by SMS. Parents responded to 5 SMS messages daily for 7 days during baseline and for 14 days during a cold. Parents provided written feedback about the SMS-based data collection at the beginning (Q1) and at the end (Q...
