“…In a weekly generation scheduling problem as considered in this paper, this approximation results in a large-scale formulation whose computational burden can be significantly higher than that of the robust optimization (RO) approach. In the literature, RO approaches have recently been applied in various problems, including UC (see, e.g., [21], [22], and [23]), system security (see, e.g., [24]), plug-in hybrid electric vehicles (see, e.g., [25]), and offering strategies (see, e.g., [26] and [27]). A key feature separating our approach from the classical RO ones is that we employ a vector autoregressive (VAR) model to analyze the seasonality of the water inflow, and accordingly generate the forecasted value and CI.…”
