Achieving Guaranteed Performance for Protection Traffic in Smart Grid Wide- Area Networks
Adrah, Charles Mawutor; Kamath, Aditya K.; Bjørnstad, Steinar; Tahiliani, Mohit P. (Chapter, 2019)Recent years, tele-protection applications in utility grids have been deployed using Ethernet. However, Ethernet without Time Sensitive Network (TSN) mechanisms is non-deterministic. Hence, challenges of the queuing delays ... -
An IP Multicast Framework for Routable Sample Value Communication in Transmission Grids
Adrah, Charles Mawutor; Yellajosula, Jaya R. A. K.; Kure, Oivind; Palma, David; Heegaard, Poul Einar (Journal article; Peer reviewed, 2019)The growth and deployment of digital substations based on IEC 61850 in power utility industry will spawn new opportunities for wide area systems. These include monitoring, protection and control applications that will ... -
Blockchain Support For Time-Critical Self-Healing In Smart Distribution Grids
Gebraselase, Befekadu; Adrah, Charles Mawutor; Zerihun, Tesfaye Amare; Helvik, Bjarne Emil; Heegaard, Poul Einar (Chapter, 2022)Smart distribution grids have new protection concepts known as fault self-healing whereby Intelligent Electronic Devices (IEDs) can automatically reconfigure the power circuits to isolate faults and restore power to the ... -
Communication Networks for Protection Systems in Smart Transmission Grids
Adrah, Charles Mawutor (Doctoral thesis, 2020)The advances in Smart electric Transmission Grids (STG) have led to new developments in wide-area protection, control and state estimation applications. Protection systems in utility grids are particularly crucial in ... -
Experimental validation of a new impedance based protection for networks with distributed generation using co-simulation test platform
Pandakov, Konstantin; Adrah, Charles Mawutor; Hoidalen, Hans Kristian; Kure, Øivind (Peer reviewed; Journal article, 2019)Combined real-time hardware-in-the-loop simulations and modeling of communication networks (co-simulation platforms) is a powerful test-bed for development and validation of relay protection schemes utilizing communication ... -
Hardware-in-the-loop testing of impedance protection with compensation of fault impedance and DG infeed current
Pandakov, Konstantin; Adrah, Charles Mawutor; Liu, Zhou; Hoidalen, Hans Kristian; Kure, Øivind (Journal article; Peer reviewed, 2018)The standard impedance protection deployed in distribution networks can malfunction due to underreach errors caused by fault impedances and remote infeed currents from embedded generators (becoming more and more widespread). ... -
A Method for Performability Study on Wide Area Communication Architectures for Smart Grid
Amare, Tesfaye; Adrah, Charles Mawutor; Helvik, Bjarne Emil (Chapter, 2019)An extensive use of ICT is a key feature in the development of next generation smart grids. The ability of the ICT system to meet the real time requirements of the powers system, even when it is degraded due to failures, ... -
A network design algorithm for multicast communication architectures in smart transmission grids
Adrah, Charles Mawutor; Palma, David; Kure, Øivind; Heegaard, Poul Einar (Peer reviewed; Journal article, 2020)In future smart transmission grids, there are distributed applications that will benefit from the deployment of Internet Protocol (IP) multicast technology for communication. Sharing of Routable-Sample Values (R-SV) and ... -
Treasure Hunt Components
Adrah, Charles Mawutor (Master thesis, 2012)The development of distributed, reactive and collaborative services is quite challenging. Rapidly composing services for collaborative learning activities require some development methods and tools. This thesis presents ...
