How to save energy on a single RTG crane system?
These strategies are developed to save energy on a single RTG crane system by employing recovered potential energy that has been generated during the lowering of the containers to charge the ESS and discharge it when the crane is lifting the containers , , , , , , , , , .
Why do RTG cranes use a deg?
RTG cranes commonly use a DEG to supply with electrical power the electric motors of the crane. The DEG allows an RTG crane to move freely within the port. Electric motors used in the crane draw energy from the generator during lifting or moving, but in case of breaking these motors may also regenerate energy.
How does a RTG crane work?
During the lifting of a container by a conventional RTG crane, the DΕG provides power and energy required by the hoist motors. During the lowering of a container, the hoist motor acts as a generator by creating regenerative braking energy. This energy is dissipated as heat to braking resistors reducing the efficiency of the RTG crane.
What are the optimal energy control studies for RTG cranes?
The optimal energy control studies for RTG cranes in , concentrate only on using recovery energy to increase energy saving in a single RTG crane system in an objective function without considering the crane prediction demand and electricity costs as an input to the ESS control strategy.
How much power does a RTG use?
The DEG usually is the only power source of the RTG, and its size is calculated by the peak power demand . The most stressful operation is the hoisting of containers, which involves power of over 400 kW and up to 3 kWh of energy . In this case study the power demand fluctuates from 10 to 292 kW.
Is RTG crane demand stochastic?
However, in reality the crane demand is naturally stochastic due the highly volatile behaviour of cranes operators. Here stochastic optimal energy management is required to efficiently minimise the energy costs and increase the peak demand reduction by dealing with the high uncertainties in RTG cranes demand.
