A modeling approach for dependability analysis of smart distribution grids
Zerihun, Tesfaye Amare; Helvik, Bjarne Emil; Heegaard, Poul Einar (Chapter, 2018)The distribution grids are among the most critical infrastructures which integrates advanced control and communication technologies atop of power systems. This paper presents a comprehensive modeling framework suited to ... -
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 ... -
Dependability Analysis of Smart Distribution Grid Architectures Considering Various Failure Modes
Zerihun, Tesfaye Amare; Helvik, Bjarne Emil (Chapter, 2018)The future smart distribution grid will be consisting of new components and technologies with enhanced capability whose failure behaviour can not be determined with certainty. In studying the reliability of these distribution ... -
Effect of Communication Failures on State Estimation of 5G-Enabled Smart Grid
Zerihun, Tesfaye Amare; Garau, Michele; Helvik, Bjarne Emil (Peer reviewed; Journal article, 2020)Information and Communication Technologies (ICT), Wide Area Measurement Systems (WAMS) and state estimation represent the key-tools for achieving a reliable and accurate knowledge of the power grid, and represent the ... -
Failure analysis and prediction in compound system by wavelets
Zerihun, Tesfaye Amare (Master thesis, 2016)The current overall ICT infrastructure mainly the Internet and Telecom networks can be looked upon as an ecosystem, which is the result of the cooperation between a huge number of Autonomous systems (ASes). The interconnection ... -
A Holistic Approach to Dependability Modeling and Analysis of Smart Distribution Grids
Zerihun, Tesfaye Amare (Doctoral theses at NTNU;2021:56, Doctoral thesis, 2021)Lately, the distribution grid has been under a significant transformation, with a pervasive integration of Information and Communication Technology (ICT) for an enhanced operation and management of the grid. Some of the ... -
Proposal and Evaluation of a New Short Circuit Protection Algorithm for Active Meshed Distribution Grids
Wirgenes, Karl Fredrik Anker (Master thesis, 2023)Masket drift av det høyspente distribusjonsnettet (DN) er en måte å motvirke fremtidig spenning og overbelastning-problematikk i DN grunnet økning i last og distribuert produksjon (DG). På grunn av økonomiske og algoritmiske ... -
