The use of supercapacitors as energy storage systems is evaluated in this work. Supercapacitors are compared with other technologies such as compressed air, pumped hydro, superconductors and flywheels. This paper is focused on medium scale energy storage systems (applied to 100 kW photovoltaic generation plants). The supercapacitor is studied in detail, presenting these device structures, how t...

Hybrid power plants (HPPs) integrating dispatchable and non-dispatchable generation are gaining attention by companies due to their increased flexibility in the operation of system. In this paper, an offering bidding framework for HPP consisting wind, photovoltaic (PV), compressed air energy storage (CAES), battery (BES), thermal units day-ahead (DA) intraday markets is presented. Moreover, int...

Energy storage devices for fluid power applications that are significantly more compact than existing ones will enable energy regeneration for many applications, including fluid power hybrid vehicles and construction equipment. The current approach to hydraulic energy storage makes use of a compressed gas enclosed in a closed chamber. As the system must contain the expanded gas and the hydrauli...

• The preliminary design method and experiment of the liquid turbine is presented. predicted experimental performance validates method. Reasonable parameter ranges for turbines are different from other turbines. Liquid can replace throttling valves to recover waste energy reduce vaporization in various industrial systems, such as liquefied natural gas, air separation, supercritical compressed s...
