  • a wireless Metering and monitoring system for solar string inverters
    International Journal of Electrical Power & Energy Systems, 2018
    Co-Authors: Ersan Kabalci, Yasin Kabalci
    Abstract:

    Abstract The design and implementation studies of a real time monitoring and Smart Metering system are presented in this study. The proposed design is improved in terms of Smart Metering infrastructure based on current, voltage, and power measurements. The communication among the string inverter and host PC is performed by the designed ZigBee transceiver system. Sensing circuits are the most significant devices for measuring both current and voltage magnitudes of the systems. The measured data are processed by the microcontroller unit (MCU) and are modulated after signal processing operations for serial communication. Although the transceiver is configured to execute bi-directional communication, unidirectional data flow is performed where the Smart Metering system transmits data to monitoring substructure. The monitoring software is also implemented in the context of the presented study. The Visual Studio software development kit is used to design and to code the software by using C#. The performed experimental studies showed that the proposed real time monitoring and Smart Metering system could be exploited to monitor current, voltage and power magnitudes of the string inverters in an efficient way.

  • persistence of the effects of providing feedback alongside Smart Metering devices on household electricity demand
    Energy Policy, 2017
    Co-Authors: Joachim Schleich, Corinne Faure, Maria Klobasa
    Abstract:

    Using large-sample high temporal resolution data from a Smart Metering field trial, we econometrically estimate the effects of providing feedback in addition to Smart Metering devices. We compare consumption levels and patterns between a pilot group that received feedback in addition to Smart Metering devices and a control group with only Smart Metering devices. We investigate, in particular, the persistence of the effects and whether the effects differ between periods of high and low household occupancy, i.e. between morning and evening periods, and between weekdays and weekend days. The findings show that feedback is effective, leading to about 5% electricity consumption reduction that is persistent over an eleven month period. Furthermore, our results show that this reduction affects both low and high occupancy periods, suggesting that feedback is associated with rather permanent changes in habitual behavior and/or investments in energy-efficient technologies.

  • alleviating solar energy congestion in the distribution grid via Smart Metering communications
    IEEE Transactions on Parallel and Distributed Systems, 2012
    Co-Authors: Nirwa Ansari
    Abstract:

    The operation and control of the existing power grid system, which is challenged with rising demands and peak loads, has been considered passive. Congestion is often discovered in high-demand regions, and at locations where abundant renewable energy is generated and injected into the grid; this is attributed to a lack of transmission lines, transfer capability, and transmission capacity. While developing distributed generation (DG) tends to alleviate the traditional congestion problem, employing information and communications technology (ICT) helps manage DG more effectively. ICT involves a vast amount of data to facilitate a broader knowledge of the network status. Data computation and communications are critical elements that can impact the system performance. In this paper, we consider congestion caused by power surpluses produced from households' solar units on rooftops or on ground. Disconnecting some solar units is required to maintain the reliability of the distribution grid. We propose a model for the disconnection process via Smart Metering communications between Smart meters and the utility control center. By modeling the surplus congestion issue as a knapsack problem, we can solve it by proposed greedy solutions. Reduced computation time and data traffic in the network can be achieved.

  • Lightweight Authentication and Key Agreement for Smart Metering in Smart Energy Networks
    IEEE Transactions on Smart Grid, 2019
    Co-Authors: Pardeep Kumar, Andrei Gurtov, Mangal Sain, Andrew Martin, Phuong H. Ha
    Abstract:

    Smart meters (SMs) are considered as foundational part of the Smart Metering infrastructure (SMI) in Smart energy networks (SENs). SM is a digital device that makes use of two-way communication between consumer and utility to exchange, manage and control energy consumptions within a home. However, despite all the features, an SM raises several security-related concerns. For instance, how to exchange data between the legal entities (e.g., SM and utility server) while maintaining privacy of the consumer. To address these concerns, authentication and key agreement in SMI can provide important security properties that not only to maintain a trust between the legitimate entities but also to satisfy other security services. This work presents a lightweight authentication and key agreement that enables trust, anonymity, integrity and adequate security in the domain of SEN. The proposed scheme employs hybrid cryptography to facilitate mutual trust (authentication), dynamic session key, integrity, and anonymity. We justify the feasibility of the proposed scheme with a test-bed using 802.15.4 based device (i.e., SM). Moreover, through the security and performance analysis, we show that the proposed scheme is more effective and energy efficient compared to the previous schemes.

  • Smart grid Metering networks a survey on security privacy and open research issues
    IEEE Communications Surveys and Tutorials, 2019
    Co-Authors: Pardeep Kumar, Yun Lin, Guangdong Bai, Andrew Paverd, Jin Song Dong, Andrew J Martin
    Abstract:

    Smart grid (SG) networks are newly upgraded networks of connected objects that greatly improve reliability, efficiency, and sustainability of the traditional energy infrastructure. In this respect, the Smart Metering infrastructure (SMI) plays an important role in controlling, monitoring, and managing multiple domains in the SG. Despite the salient features of SMI, security, and privacy issues have been under debate because of the large number of heterogeneous devices that are anticipated to be coordinated through public communication networks. This survey paper shows a brief overview of real cyber attack incidents in traditional energy networks and those targeting the Smart Metering network. Specifically, we present a threat taxonomy considering: 1) threats in system-level security; 2) threats and/or theft of services; and 3) threats to privacy. Based on the presented threats, we derive a set of security and privacy requirements for SG Metering networks. Furthermore, we discuss various schemes that have been proposed to address these threats, considering the pros and cons of each. Finally, we investigate the open research issues to shed new light on future research directions in SG Metering networks.

  • a cloud based Smart Metering infrastructure for distribution grid services and automation
    Sustainable Energy Grids and Networks, 2017
    Co-Authors: Edoardo Patti, Luca Barbierato, Abouzar Estebsari, Ferdinanda Ponci, Enrico Pons, Antonello Monti
    Abstract:

    Abstract The evolution of the power systems towards the Smart grid paradigm is strictly dependent on the modernization of distribution grids. To achieve this target, new infrastructures, technologies and applications are increasingly required. This paper presents a Smart Metering infrastructure that unlocks a large set of possible services aimed at the automation and management of distribution grids. The proposed architecture is based on a cloud solution, which allows the communication with the Smart meters from one side and provides the needed interfaces to the distribution grid services on the other one. While a large number of applications can be designed on top of the cloud, in this paper the focus will be on a real-time distributed state estimation algorithm that enables the automatic reconfiguration of the grid. The paper will present the key role of the cloud solution for obtaining scalability, interoperability and flexibility, and for enabling the integration of different services for the automation of the distribution system. The distributed state estimation algorithm and the automatic network reconfiguration will be presented as an example of coordinated operation of different distribution grid services through the cloud.

  • Low voltage system state estimation based on Smart Metering infrastructure
    2016 IEEE International Workshop on Applied Measurements for Power Systems (AMPS), 2016
    Co-Authors: Marco Pau, Luca Barbierato, Abouzar Estebsari, Edoardo Patti, Ferdinanda Ponci, Enrico Pons, Antonello Monti
    Abstract:

    The accurate monitoring of distribution grids is essential to enable the intelligent management and control of future Smart Grids. Several challenges prevent an easy development of the state estimation tools needed to assess the operating conditions of distribution networks. The lack of a suitable measurement infrastructure is one of the most challenging aspects to face. However, in last years, several utilities started a massive deployment of Smart meters in their networks. The proper use of these measurements is key to enhance the performance of distribution system state estimators. This paper presents a two-level approach conceived to efficiently include Smart meter measurements in low voltage grid state estimation. The proposed solution relies on a cloud-based Smart Metering architecture, which allows scalability and interoperability among different off-the-shelf meters. Moreover, a suitable design of the estimation algorithm, using the uncertainty propagation theory, is proposed in order to maximize the accuracy of the estimation results. Tests performed on a sample low voltage network show the performance and the main features of the proposed state estimation solution.
