Abstract
This paper presents the power distribution planning problem for integrated storage dam and run-off-river (ROR) hydroelectric power plant (HEPP) projects under supply uncertainty. The problem is formulated as a two-stage stochastic program, and numerical comparisons of the stochastic solution, expected value solution, and wait and see solutions are made. The solutions provide the economic dispatch of generators and optimal plan that the power system operators use to coordinate, control, and monitor the hydroelectric power generation and distribution systems.
