    • Characterizing flexibility in power markets and systems 

      Kara, Güray; Tomasgard, Asgeir; Farahmand, Hossein (Peer reviewed; Journal article, 2022)
      The increasing share of variable renewable energy sources creates a need for flexibility resources in the power system operations. This paper presents suggestions for characterizing flexibility, including dimensions of ...

    • Developments and Challenges in Local Electricity Markets: A Comprehensive Review 

      Bjarghov, Sigurd; Löschenbrand, Markus; Ibn Saif, A.U.N.; Pedrero, Raquel Alonso; Pfeiffer, Christian; Khadem, Shafiuzzaman K.; Rabelhofer, Marion; Revheim, Frida Huglen; Farahmand, Hossein (Journal article; Peer reviewed, 2021)
      In recent years, power systems have undergone changes in technology and definition of the associated stakeholders. With the increase in distributed renewable generation and small- to medium-sized consumers starting to ...

    • Flexibility Characterization, Aggregation, and Market Design Trends with a High Share of Renewables: a Review 

      Crespo del Granado, Pedro Andres; Rajasekharan, Jayaprakash; Pandiyan, Surya Venkatesh; Tomasgard, Asgeir; Kara, Güray; Farahmand, Hossein; Jaehnert, Stefan (Peer reviewed; Journal article, 2023)
      Purpose of Review Balancing a large share of solar and wind power generation in the power system will require a well synchronized coordination of all possible flexibility sources. This entails developing market designs ...

    • Hybrid AC/DC-OPF ADMM model for TSO coordination with multiple DSOs in Flexibility Market 

      Ivanko, Dmytro; Vågane, Ine Solsvik; Hashemipour, Seyed Naser; Oleinikova, Irina; Crespo del Granado, Pedro Andres; Farahmand, Hossein (Peer reviewed; Journal article, 2022)
      Unlocking potential from flexibility assets is an effective way to address power grid challenges. Proper coordination between transmission and distribution system operators (TSO and DSOs) is key to achieving this goal. ...

    • Impact of large-scale EV integration and fast chargers in a Norwegian LV grid 

      Lillebo, Martin; Zaferanlouei, Salman; Zecchino, Antonio; Farahmand, Hossein (Journal article; Peer reviewed, 2019)
      Norway has implemented economic incentives over several years to encourage a transition from conventional vehicles to electric vehicles (EVs), and now has the largest share of EVs per capita in the world. In this study, ...

    • The impact of uncertainty and time structure on optimal flexibility scheduling in active distribution networks 

      Kara, Güray; Pisciella, Paolo; Tomasgard, Asgeir; Farahmand, Hossein (Journal article; Peer reviewed, 2021)
      The authors focus on a model for system operators that uses centralized scheduling of multiple flexibility assets and services to minimize the cost of managing problems with grid congestion, voltages, and losses. The model ...

    • Representation of uncertainty in market models for operational planning and forecasting in renewable power systems: a review 

      Haugen, Mari; Farahmand, Hossein; Jaehnert, Stefan; Fleten, Stein-Erik (Peer reviewed; Journal article, 2023)
      As the power system is becoming more weather-dependent and integrated to meet decarbonization targets, the level and severity of uncertainty increase and inevitably introduce higher risk of demand rationing or economic ...

    • Stochastic local flexibility market design, bidding, and dispatch for distribution grid operations 

      Kara, Güray; Pisciella, Paolo; Tomasgard, Asgeir; Farahmand, Hossein; Granado, Pedro Crespo Del (Journal article; Peer reviewed, 2022)
      In order to unlock the flexibility potential of energy consumers and prosumers, the development of market mechanisms for flexibility planning and procurement is necessary. The authors propose a stochastic local flexibility ...

    • Stochastic programming in analyses of flexibility in power systems and markets 

      Kara, Güray (Doctoral theses at NTNU;2022:31, Doctoral thesis, 2022)
      Summary of the thesis In the research for this thesis, operations research techniques are applied in power markets and systems to investigate the usage of flexibility under conditions of uncertainty. Economic dispatch ...
