The liquid turbine can replace throttling valves during the depressurization process of high-pressure or supercritical fluid and improve system efficiency many industrial systems. However, there is no research about studying internal flow total pressure loss turbines, which affect performance significantly. In this paper, characteristics in a were analyzed for compressed air energy storage (SC-...

An axial compressor has high efficiency under design conditions, but its stable working range is narrow. Adjusting the rotational speed can effectively expand range. In this paper, a five-stage for specific compressed air energy storage (CAES) system taken as research object, and different (DRS) characteristics are studied with NUMECA software. Firstly, influence of DRS on overall aerodynamic p...

In this paper, the topic of Compressed Air Energy Storage (CAES) is discussed and a program in which it is being applied to a wind turbine system for leveling power supplied to the grid is described. Noted is the importance of heat transfer in the design of the compressor and its effect on performance. Presented is a design for minimizing the temperature rise in the compressor during compressio...

Direct-current (DC) microgrids have gained worldwide attention in recent decades due to their high system efficiency and simple control. In a self-sufficient energy system, voltage control is an important key dealing with upcoming challenges of renewable integration into DC microgrids, thus storage systems (ESSs) are often employed suppress the power fluctuation ensure stability. this paper, pe...

Energy storage will be required over a wide range of discharge durations in future zero-emission grids, from milliseconds to months. No single technology is well suited for the complete range. Using 9 years UK data, this paper explores how combine different energy technologies minimize total cost electricity (TCoE) 100% renewable-based grid. Hydrogen, compressed air (CAES) and Li-ion batteries ...
