Utilization of Regenerative Energy by Ultracapacitor Sizing for Peak Shaving in STS Crane
This paper presents a strategy to avoid peak demand rising and energy management due to existing cranes at container terminals (CT). The new generation of the Ship to Shore (STS) cranes installed at the port of Long Beach (POLB) are equipped with the capabilities to absorb up to 90% of the regenerative energy (RE). Hence, a percent of RE is fed into the dc-bus in an STS Crane and deliver to the Ultracapacitor (UC) bank energy storage system (ESS).
