摘要: A methodology for the optimal scheduling of hydrothermal power systems is described taking into account multiple hydro reservoir characteristics, inflow stochasticity, and transmission network represented by a linearized flow model. The solution algorithm based on stochastic dual dynamic programming (SDDP), which decomposes multistage problem several one-stage subproblems. Each subproblem corresponds to with additional constraints representing equations piecewise linear approximation expected future cost function. solved customized flow/dual simplex takes advantage characteristics reservoirs system. application illustrated in case study Brazilian system comprising 44 hydroplants, 11 thermal plants, 463 buses 834 circuits. >
