Enhanced Power Capability of Generator Units for Increased Operational Security using NMPC
Øyvang, Thomas; Nøland, Jonas Kristiansen; Sharma, Roshan; Hegglid, Gunne John; Lie, Bernt (Peer reviewed; Journal article, 2019)The ever-increasing penetration of intermittent energy sources introduces new demanding operating regimes for the bulk power generation in the power grid. During a worst-case power system disturbance scenario, the generator ... -
Future Operational Regimes of Bulk Power Generation in The Era of Global Energy Transition: Grid Codes, Challenges and Open Issues
Nøland, Jonas Kristiansen; Leandro, Matteo; Nysveen, Arne; Øyvang, Thomas (Chapter, 2020)This paper explores the effects of the ongoing energy transition on the classical bulk power generation. The rapid increase in renewable penetration changes the role of grid-connected generators significantly. Large machines ... -
State Estimation of a Thermal Model of Air-cooled Synchronous Generator
Pandey, Madhusudhan; Øyvang, Thomas; Lie, Bernt (Peer reviewed; Journal article, 2019)In this paper, we extend a previous study on a totally enclosed thermal model of a synchronous generator, with temperature state estimation using experimental data. The extension includes a new formulation of the system ... -
Transient stability of fault ride through capability of a transmission system of a distributed hydropower system
Manjula, Edirisinghe V. P. J.; Øyvang, Thomas; Hegglid, Gunne John (Journal article; Peer reviewed, 2017)This paper describes the Fault Ride Through (FRT) capability of generators of a part of the 132 kV high voltage power network in Telemark region, Norway using a simplified power system simulator model. The organization, ...
