Our experiments are executed on two distinct compute platforms. The first represents a commodity higher-end workstation, and consists of eight 8-core AMD Opteron 6278 2.4 GHz processors with 512 GB of RAM. Such a workstation is representative of the type of resource that is likely to be currently … See more The overall run-time of PH is largely a function of the difficulty of individual scenario sub-problems, both with and without the augmented objective terms. Thus, we begin the … See more Our results demonstrate that careful tuning of the PH configuration can yield “natural” convergence to a fully non-anticipative solution. However, in general, additional mechanisms may be employed in cases where this … See more Next, we analyze the computational difficulty of the extensive form of the WECC-240-r1instance, as a function of the number of scenarios … See more As discussed in Sect. 3, there are three key parameters underlying our PH algorithm for stochastic UC: the scale factor \alpha used to compute the \rho values for individual generator commitment variables, the choice … See more WebJan 1, 2013 · Request PDF On Jan 1, 2013, S.M.
