“…Approaches to convexify the hydropower production function within the longterm models are presented in [23]- [25]. Other examples of nonconvexities are due to irrigation [26] and river level and river-routing constraints [27].…”

“…In addition to (7), ramp-up and ramp-down limits, startup and shut-down ramp limits and minimum up and downtime constraints were modeled following the equations (16)- (26) in [38] (Section II B). We do not explicitly state these equations here for brevity.…”

“…When (and if) the storage volume in the reservoir reach the predefined threshold, the constraint changes into a minimum reservoir level constraint. This can be imposed by (17) and (18). ( 17) is active for the first week the storage volume in the reservoir reach the wanted threshold (in t C ), while (18) becomes active from the following week.…”

“…Nonconvex problem formulations are typically needed to represent the complex interaction between power output and water [12], and unit commitment of generators [13]. The challenge of representing nonconvex relationships in the SDDP algorithm has frequently been addressed in the literature by the use of approximations, e.g [14]- [17]. A few studies also consider accurate modelling of non-convexities by the use of SDP [18] or stochastic dual dynamic integer programming (SDDiP), such as in [19] and [20].…”
