THE PUMPED-STORAGE HYDRO POWER PLANT MODEL WITHIN IN THE POWER SYSTEM RELIABILITY AND AVAILABILITY MODEL

Abstract

This paper deals with a model that comprises the pumped-storage hydro power plants in the power system reliability and availability calculations, as well as a model of the impact of inflow deficiency and water storage risks on the operational planning of such plants within the framework of operational planning systems for periods of up to one year. The impact of inflow uncertainties is related to the characteristics of watercourses where the water storage reservoirs and hydro power plants are built, but also to the operation cycles and possible operation modes in the system.
