Continuous Hydrothermal Flexibility Coordination Under Wind Power Uncertainty
Naversen, Christian Øyn; Parvania, Masood; Helseth, Arild; Farahmand, Hossein (Peer reviewed; Journal article, 2022)This paper develops a stochastic continuous-time optimization model for coordinating the operation of flexibility in a hybrid hydro-thermal-wind power system. The developed model gives insight for investigating the short-term ... -
Frequency Quality in the Nordic Power System: Wind Variability, Hydro Power Pump Storage and Usage of HVDC Links
Endegnanew, Atsede Gualu; Farahmand, Hossein; Huertas-Hernando, Daniel (Peer reviewed; Journal article, 2013)This work investigates the effect that variable power production from offshore wind farms in the North Sea will have together with the use of pumped storage facilities at hydropower stations in Norway, on the Nordic ... -
Hydrothermal scheduling in the continuous-time framework
Naversen, Christian Øyn; Helseth, Arild; Li, Bosong; Parvania, Masood; Farahmand, Hossein; Catalao, João P.S. (Peer reviewed; Journal article, 2020)Continuous-time optimization models have successfully been used to capture the impact of ramping limitations in power systems. In this paper, the continuous-time framework is adapted to model flexible hydropower resources ... -
The Impact of Active Power Losses on the Wind Energy Exploitation of the North Sea
Farahmand, Hossein; Warland, Leif; Huertas-Hernando, Daniel (Peer reviewed; Journal article, 2014)Transmission active power losses can influence the distribution of power flows in the transmission grid which consequently alter the generation dispatch and scheduling through the power system. This can especially affect ... -
Modelling Minimum Pressure Height in Short-term Hydropower Production Planning
Dorn, Frederic; Farahmand, Hossein; Skjelbred, Hans Ivar; Belsnes, Michael Martin (Journal article; Peer reviewed, 2016)When planning the production for certain hydropower plants, minimum pressure is one of the major critical points. Violation of the minimum pressure causes the power plant to automatically shut down, hence violating the ... -
Multi-Market Price Forecasting in Hydro-Thermal Power Systems
Helseth, Arild; Haugen, Mari; Jaehnert, Stefan; Mo, Birger; Farahmand, Hossein; Naversen, Christian Øyn (Chapter; Peer reviewed, 2018)This paper presents a framework for price forecasting in hydro-thermal power systems. The framework consists of a long-term strategic and a short-term operational model. The strategic model provides the end-of-horizon ... -
A stochastic operational planning model for a zero emission building with emission compensation
Thorvaldsen, Kasper Emil; Korpås, Magnus; Lindberg, Karen Byskov; Farahmand, Hossein (Peer reviewed; Journal article, 2021)The primary objective of Zero Emission Buildings (ZEBs) is to achieve net zero emission over the buildings’ lifetime. To achieve this goal, accurate cost-effective emission compensation is needed during the operational ... -
Task 16.3 Nordic hydro power generation flexibility and transmission capacity expansion to support the integration of Northern European wind power production: 2020 and 2030 case studies
Farahmand, Hossein; Jaehnert, Stefan; Aigner, Tobias; Huertas-Hernando, Daniel (Report, 2013-03-03) -
Validation study of an approximate 2014 European power-flow model using PowerGAMA
Lie, Arne Øvrebø; Rye, Eirik Andre; Svendsen, Harald Georg; Farahmand, Hossein; Korpås, Magnus (Journal article; Peer reviewed, 2017)This study presents a validation study of an approximated model of the European power system in 2014. A lightweight and open-source power-flow tool is used for this study. The tool and the model are publicly available and ...
