This paper reports on a case study for Ghana's thermal/hydroelectric generation system that evaluates the incremental cost of returning dam outflows to pre-dam or near pre-dam conditions. This mode of operation is termed Run of River (ROR) operation. It appears that two key factors - the availability of alternatives for economically expanding hydro generation and the existence of well developed markets...
This paper presents the strategy for development of a stochastic programming model of the operation and capacity additions to a large hydro/thermal electricity generation complex. The proposed model minimizes the incremental costs of operating the complex so as to return river flows to pre-dam patterns. The paper focuses on a representative year made up of wet and dry seasons far enough into the future...
This paper introduces a convex and normally constrained hydrothermal scheduling method. Convexity is achieved by using a hydro water loss term and a piece-wise linear representation of the relationship between water head and volume. A basic technique is developed for obtaining normal constraints, developed for the first time in this paper, by converting the conditional constraints into unconditional...
