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 ... -
Dynamic incorporation of nonlinearity into MILP formulation for short-term hydro scheduling
Skjelbred, Hans Ivar; Kong, Jiehong; Fosso, Olav B (Journal article; Peer reviewed, 2019)Optimization tools are widely used for solving the short-term hydro scheduling (STHS) problem in a cascaded hydro system. In a mixed integer linear programming (MILP)-based formulation, the nonlinear and non-convex hydropower ... -
Impact of energy pricing regimes on production schedules under solar-hydro hybridization
Kong, Jiehong; Sheppard, Alexandra Jane; Nøvik, Hanne; Engelstad, Øyvind; Fjelldal, Bjørnar; Klæboe, Gro; Skjelbred, Hans Ivar (Chapter, 2023)Hybridization of complementary energy production increases system flexibility and allows optimization of energy and resource availability. Hydropower and floating solar photovoltaics (FPV) have a high potential for ... -
Machine Learning for Hydropower Scheduling: State of the Art and Future Research Directions
Bordin, Chiara; Skjelbred, Hans Ivar; Kong, Jiehong; Yang, Zhirong (Peer reviewed; Journal article, 2020)This paper investigates and discusses the current and future role of machine learning (ML) within the hydropower sector. An overview of the main applications of ML in the field of hydropower operations is presented to show ... -
Optimal Pricing of Production Changes in Cascaded River Systems with Limited Storage
Riddervold, Hans Ole; Skjelbred, Hans Ivar; Kong, Jiehong; Elvetun, Ole Løseth; Korpås, Magnus (Chapter, 2019)Optimization of hydroelectric power production is often executed for river systems consisting of several powerplants and reservoirs located in the same region. For hydropower stations located along the same river, the ...
