A Virtual synchronous machine implementation for distributed control of power transformers in SmartGrids
D'Arco, Salvatore; Suul, Jon Are Wold; Fosso, Olav B (Journal article; Peer reviewed, 2015)The ongoing evolution of the power system towards a “SmartGrid” implies a dominant role of powerelectronic converters, but poses strict requirements on their control strategies to preserve stability andcontrollability. In ... -
An overview on formulations and optimization methods for the unit-based short-term hydro scheduling problem
Kong, Jiehong; Skjelbred, Hans Ivar; Fosso, Olav B (Journal article; Peer reviewed, 2019)The short-term hydro scheduling (STHS) problem aims at determining the optimal power generation schedules for either a single hydropower plant or an integrated system of cascaded watercourses during a time horizon from a ... -
Non-linear charge-based battery storage optimization model with bi-variate cubic spline constraints
Aaslid, Per; Geth, Frederik; Korpås, Magnus; Belsnes, Michael Martin; Fosso, Olav B (Peer reviewed; Journal article, 2020)Variable renewable generation demands increasing amount of flexible resources to balance the electric power system, and batteries stand out as a promising alternative.

Small-signal modeling and parametric sensitivity of a virtual synchronous machine in islanded operation
D'Arco, Salvatore; Suul, Jon Are Wold; Fosso, Olav B (Journal article; Peer reviewed, 2015)The concept of Virtual Synchronous Machines (VSMs) is emerging as a flexible approach for controlling power electronic converters in grid-connected as well as in stand-alone or microgrid applications. Several VSM implementations ... -
Static and dynamic eigenvalues in unified stability studies
Khodaparast, Jalal; Fosso, Olav B; Molinas Cabrera, Maria Marta; Suul, Jon Are Wold (Peer reviewed; Journal article, 2022)A framework for unified analysis of small-signal and large-signal power system stability based on static and dynamic eigenvalues is proposed in this paper. The presented implementation is based on Gear's method, which is ... -
Stochastic operation of energy constrained microgrids considering battery degradation
Aaslid, Per; Korpås, Magnus; Belsnes, Michael Martin; Fosso, Olav B (Peer reviewed; Journal article, 2022)Power systems with high penetration of variable renewable generation are vulnerable to periods with low generation. An alternative to retain high dispatchable generation capacity is electric energy storage that enables ... -
Stochastic Optimization of Microgrid Operation With Renewable Generation and Energy Storages
Aaslid, Per; Korpås, Magnus; Belsnes, Michael Martin; Fosso, Olav B (Peer reviewed; Journal article, 2022)The operation of energy storage systems (ESSs) in power systems where variable renewable energy sources (VRESs) and ESSs must contribute to securing the supply, can be considered as an arbitrage against scarcity. The value ... -
Switching sequences for non-predictive declutching control of wave energy converters
Garcia Rosa, Paula Bastos; Fosso, Olav B; Molinas Cabrera, Maria Marta (Peer reviewed; Journal article, 2021)Aiming at improving the energy absorption from waves, a number of studies have considered declutching control - a phase-control method that consists of disengaging the power take-off (PTO) system from the oscillating body ...
