APPLICATION OF THE FIREWORKS ALGORITHM FOR DESIGN OPTIMIZATION OF DOUBLE PANCAKE SUPERCONDUCTING INDUCTIVE ENERGY STORAGE DEVICE

The article deals with optimization problem of double pancake coil design parameters, intended for superconducting magnetic energy storage system. The corresponding problem formulation involves the search for the maximum stored energy of magnetic field for fixed length of second generation superconducting tape at temperatures of 22° K and 77° K. The optimization method used is based on fireworks algorithm with an improved selection strategy for choosing intermediate solutions. The stored energy of the storage system is determined by jointly solving integral equation of magnetic field and the equation of critical state of superconducting material. A series of numerical experiments was carried out in order to compare the main characteristics of the proposed strategy for implementing the fireworks algorithm with alternative optimization technologies, including the traditional implementation of this method, as well as the genetic algorithm.
