Supercapacitors as energy buffers : a solution for elevators and for electric busses supply
Supercapacitors are components for energy storage, well dedicated for applications where energy storage can help to the smoothing of strong and short time power solicitations of a distribution network. Those properties are developed for two examples. The first one is regarding an elevator, where a low constant power is provided by a distribution power indipendently of the maximum peak power needed for the lift, thanks to intermediary supercapacitors. the second example deals with the voltage drop compensation in weak distribution systems, for maintaining constant the voltage at the end of a supply line for trolley buses avoiding the use of heavy and expensive supply station.
