An Improved Multi-Verse Optimizer Algorithm For Solving The Analytic Model Of Grid Fault Diagnosis

The analytical model of grid fault diagnosis can convert the fault diagnosis problem into a 0-1 integer planning problem for solving the minimum value, so that the objective function can be solved by mathematical solution methods to get the final set of fault components. In view of the problems of omission of solutions that may occur in the processing of traditional grid analytical model problems, the corresponding weights of all levels of protection and circuit breakers are taken into account on the basis of the original analytical model, so as to make the analytical model of faults more consistent with the actual relay protection device hierarchical coordination relationship; on this basis, a grid fault diagnostic analysis model solution method based on the multivariate universe optimization algorithm is also given, aiming at the fast solution of the improved fault analysis model. The improved grid analysis model using multi-verse optimization algorithm is shown to be highly accurate with good performance of fast convergence by solving cases on IEEE14 node system.
