Pumped storage power station is an economic and reliable means of peak load regulation for networks. The temperature humidity control are complicated due to the huge amount heat moisture emission in main plant. This paper investigates operating condition three different ventilation cases a five-storey underground pumped station. A full-scale model plant was built numerical simulation. Three wer...

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

Liquid air energy storage (LAES) is a novel technology for grid scale electrical energy storage in the form of liquid air. At commercial scale LAES rated output power is expected in the range 10 to 100 MWe, while the storage capacity of the order of 100s of MWhe. LAES comprises three processes: charging, consisting in air liquefaction; storage, involving preservation of air in liquid form; and ...

In this paper, the contribution of a hydraulic short-circuit pumped-storage power plant (HSCPSPP) to the load–frequency regulation (LFR) of an isolated power system has been further analyzed by means of simulations. For this purpose, a simulation model has been developed that considers the AGC system and both the synchronized thermal units’ and the HSCPSPP’s response to frequency deviations and...

Renewable energy resources have played an important role to meet increasing energy demand in the world. Among the renewable energy resources, especially, wind energy is of interest due to some advantages, such as being clean, environmental friendly etc. However, the intermittent nature of wind creates several problems to the power system operation and new approaches based on the combined use of...

Modeling of regulating system of large pumped storage power station with long pipeline and parameters optimization in transient processes are studied in this paper. According to the actual parameters of a certain pumped storage power station, MATLAB/Simulink toolbox is utilized for modeling and simulation of its subsystems. Friction resistance coefficient and water elasticity are taken into con...
