Modelling overfow using mixed integer programming in short‑term hydropower scheduling
Litlabø, Tormod; Aaslid, Per; Riise, Tarjei Lid; Haugland, Dag (Peer reviewed; Journal article, 2023)Short-term hydropower scheduling seeks to find a production schedule that maximizes profit, but must also consider the hydrological balance and risk of overflow. Overflow is by nature a non-linear and non-convex phenomenon. ... -
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. Battery models for optimization typically represent ... -
Optimal microgrid operation considering battery degradation using stochastic dual dynamic programming
Aaslid, Per; Belsnes, Michael Martin; Fosso, Olav B (Chapter; Peer reviewed, 2019) -
Pricing electricity in constrained networks dominated by stochastic renewable generation and electric energy storage
Aaslid, Per; Korpås, Magnus; Belsnes, Michael Martin; Fosso, Olav B (Peer reviewed; Journal article, 2021)This paper studies the electricity price formation in a competitive market when introducing generation from variable renewable energy technologies with zero marginal cost and electric energy storage systems. A power system ... -
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 ...
