The pumped storage power station is flexible to start, can realize effective of electric energy, and has superior peak frequency modulation effects, which beneficial provide comprehensive benefits the system. But at present, construction pumped-storage plants obviously exceeded speed policy market development, resulting in problems operation cost reduction. Aiming this problem, paper further ex...

Abstract In pump turbines, the observation in engineering field shows that pressure fluctuation has become one of most serious hydraulic instability phenomena. The pulsation will cause vibration and fatigue failure unit, even plant, which greatly affects safe operation power station. this paper, research on by domestic foreign researchers is introduced discussed. It includes characteristics var...

Energy storage is a key issue when integrating large amounts of intermittent and nondispatchable renewable energy sources into electric power systems. To be able to maintain the instantaneous power balance and to compensate for the influence of power fluctuations that might result from renewable sources, flexible capability for power control is needed. Therefore, sufficient energy storage with ...

Pumped storage power plants face many challenges in competing the electricity market, and high pumping costs lead to prices for their generation, which is one of important factors that has limited development. To address this problem, paper studies pumped two-part tariff mechanism considering wind accommodation uses peak-valley price difference realize rationality economy a charging discharging...
