Internet of Things-aided Smart Grid: Technologies, Architectures, Applications, Prototypes, and Future Research Directions
Traditional power grids are being transformed into Smart Grids (SGs) to
address the issues in existing power system due to uni-directional information
flow, energy wastage, growing energy demand, reliability and security. SGs
offer bi-directional energy flow between service providers and consumers,
involving power generation, transmission, distribution and utilization systems.
SGs employ various devices for the monitoring, analysis and control of the
grid, deployed at power plants, distribution centers and in consumers' premises
in a very large number. Hence, an SG requires connectivity, automation and the
tracking of such devices. This is achieved with the help of Internet of Things
(IoT). IoT helps SG systems to support various network functions throughout the
generation, transmission, distribution and consumption of energy by
incorporating IoT devices (such as sensors, actuators and smart meters), as
well as by providing the connectivity, automation and tracking for such
devices. In this paper, we provide a comprehensive survey on IoT-aided SG
systems, which includes the existing architectures, applications and prototypes
of IoT-aided SG systems. This survey also highlights the open issues,
challenges and future research directions for IoT-aided SG systems
A survey on cyber security for smart grid communications
A smart grid is a new form of electricity network with high fidelity power-flow control, self-healing, and energy reliability and energy security using digital communications and control technology. To upgrade an existing power grid into a smart grid, it requires significant dependence on intelligent and secure communication infrastructures. It requires security frameworks for distributed communications, pervasive computing and sensing technologies in smart grid. However, as many of the communication technologies currently recommended to use by a smart grid is vulnerable in cyber security, it could lead to unreliable system operations, causing unnecessary expenditure, even consequential disaster to both utilities and consumers. In this paper, we summarize the cyber security requirements and the possible vulnerabilities in smart grid communications and survey the current solutions on cyber security for smart grid communications. © 2012 IEEE
Multy Utility Service Infrastructure (Musi) Berbasis Oplc Untuk Implementasi Smart Grid Communication Network
Lahirnya konsep Smart Grid tidak lepas dari issue global terkait dampak lingkungan hidup akibat penggunaan energy berbahan fosil secara massif yang semakin hari cadangan energy yang tersimpan akan habis dalam beberapa tahun kedepan dan diperlukan sumber energy baru yang terbarukan (non fosil). Implementasi Smart Grid sudah banyak di terapkan dibeberapa negara, termasuk di Indonesia, konsep Smart Grid dan prototipe sudah diimplementasikan dibeberapa kota walau populasinya belum banyak. Pilar utama selain listrik, dalam konsep Smart Grid ini adalah komunikasi dan IT, dimana diperlukan komunikasi dua arah antar mesin dan saling terintegrasi antar grid. Pada kanvas ini diusulkan konsep MUSI (Multy Utility Service Infrastructure) sebagai media komunikasi dalam implementasi Smart Grid dengan menggunakan jenis kabel OPLC (Optical Low Composite Cable), dimana dua infrastruktur yang berbeda menjadi satu konsep. Pada pembahasan ini metode yang digunakan adalah studi literature, pengamatan dan data, ondesk survey, analisa keekonomian (techno economy) dan pengambilan kesimpulan. Hasil dari analisa finansial yang dilakukan bahwa dengan menggunakan model MUSI yang diajukan, NPV dengan MARR 20% didapatkan nilai positif, dan IRR sekitar 34%, sementara jika dilakukan dengan metode konvensional, NPV dengan MARR 20% didapatkan nilai negatif, dan IRR dibawah 0% (negatif)
The role of communication systems in smart grids: Architectures, technical solutions and research challenges
The purpose of this survey is to present a critical overview of smart grid concepts, with a special focus on the role that communication, networking and middleware technologies will have in the transformation of existing electric power systems into smart grids. First of all we elaborate on the key technological, economical and societal drivers for the development of smart grids. By adopting a data-centric perspective we present a conceptual model of communication systems for smart grids, and we identify functional components, technologies, network topologies and communication services that are needed to support smart grid communications. Then, we introduce the fundamental research challenges in this field including communication reliability and timeliness, QoS support, data management services, and autonomic behaviors. Finally, we discuss the main solutions proposed in the literature for each of them, and we identify possible future research directions
