    • BATTPOWER Toolbox: Memory-Efficient and High-Performance Multi-Period AC Optimal Power Flow Solver 

      Zaferanlouei, Salman; Farahmand, Hossein; Vadlamudi, Vijay Venu; Korpås, Magnus (Peer reviewed; Journal article, 2021)
      In this paper, we introduce an Interior Point-based (IP) Multi-Period AC Optimal Power Flow (MPOPF) solver for the integration of Stationary Energy Storage Systems (SESS) and Electric Vehicles (EV). The primary methodology ...

    • Coordination of Frequency Reserves in an Isolated Industrial Grid Equipped With Energy Storage and Dominated by Constant Power Loads 

      Mota, Daniel dos Santos; Alves, Erick Fernando; D'Arco, Salvatore; Sanchez Acevedo, Santiago; Tedeschi, Elisabetta (Peer reviewed; Journal article, 2023)
      This paper examines the use of interconnected synchronous system requirements for frequency containment reserves (FCR) on isolated industrial grids that use turbogenerators as main source of energy, have high penetration ...

    • Dynamics and Stability of Meshed Multiterminal HVDC Networks 

      Sanchez Acevedo, Santiago; Bergna-Diaz, Gilbert; Tedeschi, Elisabetta; Garces Ruiz, Alejandro (Journal article; Peer reviewed, 2018)
      This paper investigates the existence of an equilibrium point in multiterminal HVDC grids, assesses its uniqueness and defines conditions to ensure its stability. An offshore multiterminal HVDC system including two wind ...

    • Enhanced Power Capability of Generator Units for Increased Operational Security using NMPC 

      Øyvang, Thomas; Nøland, Jonas Kristiansen; Sharma, Roshan; Hegglid, Gunne John; Lie, Bernt (Journal article; Peer reviewed, 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 ...

    • Estimation of Power System Inertia From Ambient Wide Area Measurements 

      Tuttelberg, Kaur; Kilter, Jako; Wilson, Douglas; Uhlen, Kjetil (Journal article, 2018)
      This study presents a method of estimating the effective inertia of a power system from ambient frequency and active power signals measured by phasor measurement units. Most importantly, we demonstrate that inertia can be ...

    • Multiple Nash Equilibria in Electricity Markets with price-making Hydrothermal Producers 

      Löschenbrand, Markus; Korpås, Magnus (Journal article; Peer reviewed, 2018)
      This paper proposes a novel approach incorporating scheduling decisions into a multinodal multiperiod Cournot game. Through applying the Nikaido-Isoda function, market clearing is conducted without dual values being required. ...

    • Passivity-Based Control of Power Systems Considering Hydro-Turbine with Surge Tank 

      Gil Gonzales, Walter Julian; Garces, Alejandro; Fosso, Olav B; Escobar, Andres (Journal article; Peer reviewed, 2019)
      This paper proposes an interconnection and damping assignment passivity-based control (IDA-PBC) for multimachine power systems including hydro-turbine governing systems (HTGS) with surge tank. The main objective is to ...

    • Research on common-mode and dependent (CMD) outage events in power systems: a review 

      Papic, Milorad; Agarwal, Sudhir; Allan, Ron N.; Billinton, Roy; Dent, Chris J.; Ekisheva, Svetlana; Gent, Daniel; Jiang, Kai; Li, Wenyuan; Mitra, Joydeep; Pitto, Andrea; Schneider, Alexander; Singh, Chanan; Vadlamudi, Vijay Venu; Varghese, Matthew (Journal article; Peer reviewed, 2017)
      The purpose of this paper is to present a review of some fundamental concepts and practical applications in the area of common-mode and dependent (CMD) outage events in power systems. The paper is a result of ongoing ...

    • Sufficient Conditions for Robust Frequency Stability of AC Power Systems 

      Alves, Erick Fernando; Bergna-Diaz, Gilbert; Brandao, Danilo; Tedeschi, Elisabetta (Peer reviewed; Journal article, 2020)
      This paper analyses the frequency stability of ac grids in the presence of non-dispatchable generation and stochastic loads. Its main goal is to evaluate conditions in which the system is robust to large, persistent active ...

    • System impact studies for near 100% renewable energy systems dominated by inverter based variable generation 

      Holttinen, Hannele; Kiviluoma, Juha; Flynn, Damian; Smith, Charles; Orths, Antje; Eriksen, Peter Børre; Cutululis, Nicolaos Antonio; Söder, Lennart; Korpås, Magnus; Estanqueiro, Ana; MacDowell, Jason; Tuohy, Aidan; Vrana, Til Kristian; O'Malley, Mark (Peer reviewed; Journal article, 2020)
