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...

Suitable and accurate flow measurement in pumped storage hydropower plants (PSP) is a challenging task due to the entirely different hydraulic behaviour of penstock. This study presents novel approach choosing suitable method position. The focus on specific short penstock largest peak-load plant, Orlík, after its transformation PSP. Our based three main pillars: numerical modelling fluid (ANSYS...

Transition from fossil fuels to renewable sources is inevitable. In this direction, variation and intermittency of renewables can be integrated into the grid by means of hybrid systems which operate as a combination of alternative resources, energy storage and long distance transmission lines. In this study, we propose a two-stage stochastic mixed-integer programming model for sizing an integra...

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...

Compared with the traditional GIS station, complex wiring and operation mode of pumped-storage plant diversity, working condition frequent transformation, makes to produce very fast transient overvoltage (VFTO) probability increase greatly. VFTO will form a coupled shell casing earth voltage (TEV), then station personnel safety reliability secondary equipment poses great threat. But at moment b...
