Scenarios for multistage stochastic programs
WebSince this unsupervised data mining method is fast, efficient, and simple, it is implemented for the scenario reduction in the proposed stochastic self-scheduling problem. The flowchart of K-means method is depicted in Fig. 3 [49]. In this study, the number of initial scenarios, which are obtained via Monte Carlo simulation, is 1000. WebRecent studies by electric utility companies indicate that maximum benefits of distributed solar photovoltaic (PV) units can be reaped when siting and sizing of PV systems is optimized. This paper develops a two-stage stochastic program that serves as a tool for optimally determining the placing and sizing of PV units in distribution systems. The PV …
