Data set for power system reliability analysis using a four-area test network
Sperstad, Iver Bakken; Solvang, Espen Hafstad; Jakobsen, Sigurd Hofsmo; Gjerde, Oddbjørn (Peer reviewed; Journal article, 2020)This article presents a test data set combining data relevant for power system reliability analysis, including network data, reliability data, basic interruption cost data, and exemplary operating state data. The data set ... -
Dynamic simulation of simultaneous HVDC contingencies relevant for vulnerability assessment of the nordic power system
Solvang, Espen Hafstad; Sperstad, Iver Bakken; Jakobsen, Sigurd Hofsmo; Uhlen, Kjetil (Chapter; Peer reviewed, 2019) -
Graph Convolutional Networks for probabilistic power system operational planning
Sheikh-Mohamed, Yasmin Bashir; Jakobsen, Sigurd Hofsmo; Bødal, Espen Flo; Haugseth, Fredrik Marinius; Kiel, Erlend Sandø; Riemer-Sørensen, Signe (Chapter; Peer reviewed, 2023)Probabilistic operational planning of power systems usually requires computationally intensive and time consuming simulations. The method presented in this paper provides a time efficient alternative to predict the ... -
A graph-based modelling framework for vulnerability analysis of critical sequences of events in power systems
Sperstad, Iver Bakken; Solvang, Espen Hafstad; Jakobsen, Sigurd Hofsmo (Journal article; Peer reviewed, 2020)Major blackouts may have critical societal consequences and are very challenging to analyse and mitigate. Part of the challenge lies in the complex sequences of events that characterize such blackouts and that involve a ... -
Modelling of corrective actions in power system reliability analysis
Sperstad, Iver Bakken; Jakobsen, Sigurd Hofsmo; Gjerde, Oddbjørn Idar (Chapter; Peer reviewed, 2015)Consequence analysis, including the modelling of corrective actions, is an important component when performing power system reliability analyses. Using an integrated methodology for power system reliability analysis, we ... -
An Open-Source Many-Scenario Approach for Power System Dynamic Simulation on HPC Clusters
Zhang, Junjie; Razik, Lukas; Jakobsen, Sigurd Hofsmo; D'Arco, Salvatore; Benigni, Andrea (Peer reviewed; Journal article, 2021)In this paper we introduce an approach to accelerate many-scenario (i.e., hundreds to thousands) power system simulations which is based on a highly scalable and flexible open-source software environment. In this approach, ... -
An open-source tool for reliability analysis in radial distribution grids
Jakobsen, Sigurd Hofsmo; Garau, Michele; Mo, Olve (Chapter; Peer reviewed, 2021)We present an open-source software implementation of an approximate contingency enumeration approach for calculating reliability in distribution grids based on RELRAD. The tool is coded using the efficient programming ... -
Probabilistic operational planning using dynamic programming with time-domain simulations
Bødal, Espen Flo; Jakobsen, Sigurd Hofsmo; Gjerde, Oddbjørn (Peer reviewed; Journal article, 2022)A dynamic programming model with time-domain simulations of contingencies is created to find the least-costly operational strategies according to a probabilistic operational criterion with selected preventive and corrective ... -
Tekniske retningslinjer for tilknytning av produksjonsenheter, med maksimum aktiv effektproduksjon mindre enn 10 MW, til distribusjonsnettet - Rev.02
Marvik, Jorun Irene; Kolstad, Magne Lorentzen; Jakobsen, Sigurd Hofsmo (SINTEF Rapport;, Research report, 2019) -
A tree based classifier for transient stability prediction following island splitting
Kiel, Erlend Sandø; Jakobsen, Sigurd Hofsmo; Haugen, Eirik; Lundemo, Sondre Duna; Riemer-Sørensen, Signe; Remonato, Filippo (Chapter, 2022)An unexpected failure or outage of one or multiple system components can cause a new operational situation that requires remedial actions. An important remedial action to model correctly is islanding. Finding the transient ... -
Vulnerability analysis of HVDC contingencies in the Nordic power system
Sperstad, Iver Bakken; Kjølle, Gerd Hovin; Gjerde, Oddbjørn; Vrana, Til Kristian; Jakobsen, Sigurd Hofsmo; Turunen, J.; Haarla, L (Chapter; Peer reviewed, 2018)In the increasingly interconnected and integrated European power system, transmission system operators need to consider new kinds of risk associated with the interconnection to neighbouring systems. For the Nordic power ...
