6 FAQs about [Madagascar crane energy storage system]
What is the MPC scheme for RTG cranes with the ESS?
Outline of the MPC scheme for the network of RTG cranes with the ESS. The minimum cost function for the MPC controller, is described in (8), and has previously been applied by the authors to optimise the energy of an ESS by generating a control signal to minimise the peak demand and electricity energy cost .
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 , , , , , , , , , .
How much energy does a crane use?
Quantifying the energy demand, we see that the crane is active about 50% of the entire operation time of which about 62% of the energy is used by the hoist motors, 31% is used by the gantry motors and about 10% is for the trolley and losses . For the remaining time the crane is in idle mode with the DEG switched on consuming diesel fuel.
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.
How energy storage technology can be used in power system networks?
There are a wide range of energy storage technologies that can be used in power system networks in order to increase energy cost saving and reduce peak demand. The batteries’ energy storage such as lithium-ion or NiCd batteries have been used widely mainly in ports and low voltage applications in power system networks , , .
How much power does a RTG crane use?
In RTG cranes the power peak is at 292 kW when the container is accelerated upwards while the power demand drops at 225 kW to maintain a constant speed of 26 m/min. During deceleration the peak power reaches 170 kW when the hoist motor lowers the container. For this single move the average power demand is 61.6 kW.
