Sažetak
Two parts of this paper represent a contribution to implementation of a pump-storage hydroelectric power plant stochastic model into a power plant system reliability model. Part II provides the method for determining the probability distribution of required pumping capacity of a pump-storage plant with natural inflow, and then the insertion of pump-storage hydro plants into the reliability model of the entire electrical energy production system. The inflow is thereby treated as a random variable, and stochastic modelling relies on the well-known method of constant and variable energy production. The model developed is suitable to create an additional decision-making criterion for studies related to expansion planning strategy of generating capacities in power systems. The stochastic models presented in this paper are illustrated by simple numerical examples.
