Optimal energy management of a retrofitted Rubber Tyred Gantry Crane

The methodology for sizing the battery storage system, is reported in Ref. [27]. The typical average power of a RTG crane is 24.8 kW. The storage system is expected to have an autonomy of 90 to 120 min when solely supplying the RTG operation. Therefore, the battery storage system with a capacity of 37.2 to 49.6 kWh can be proposed.

6 FAQs about [Laos crane energy storage system]

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.

Does a rubber tyred gantry crane save energy?

Net energy savings in Rubber Tyred Gantry cranes equipped with an active front end. EEEIC 2016 - International Conference on Environment and Electrical Engineering, Institute of Electrical and Electronics Engineers Inc.; 2016.

What are energy storage systems?

Energy storage systems (ESS) play an essential role in providing continuous and high-quality power. ESSs store intermittent renewable energy to create reliable micro-grids that run continuously and efficiently distribute electricity by balancing the supply and the load .

What are some recent developments in energy storage systems?

More recent developments include the REGEN systems . The REGEN model has been successfully applied at the Los Angeles (LA) metro subway as a Wayside Energy Storage System (WESS). It was reported that the system had saved 10 to 18% of the daily traction energy.

How can ESS control reduce fuel consumption during a hoist crane cycle?

The control model has been designed to find the ESS power output that minimises the fuel consumption during a hoist crane cycle by estimating the load power during the cycle. However, the proposed control algorithm requires full instantaneous knowledge of the fuel consumption and costs.
