Regulation strategy of an Ultracapacitor storage model for a gantry crane

This paper presents, for a system consisting of a gantry crane, the regulation strategy of an Ultracapacitor (UC) based storage system, and its performance test using a simulated model of the system A model for the study of the accumulation of electrical energy in Ultracapacitors was presented. This model was validated by comparing the simulation model data with experimental data obtained for a gantry crane with 22kW of nominal power. The validated model was used to investigate the behavior of the system for two different capacitance values, while maintaining unchanged the amount of energy drawn from the grid during the whole work cycle (lifting and descending). This investigation can allow to establish in each case, varying the number of work cycles per day and the cost of the plant. whether it is more advantageous to increase the capacity of the UCs reducing the size of the power plant design or, vice versa.
