Abstract :
The optimization algorithm for High-Temperature Superconducting (HTS)
Fault Current Limiters (FCL) normally includes some non-commensurable criteria or
objectives such as cost, limiting factor, thermal stresses, and mechanical stresses that
should be minimized or maximized concurrently in a protracted optimization process.
It can be performed only by tools which rstly describe the HTSFCL precisely and
predict its limitation behavior and then select the optimum design using optimization
algorithm. Multi-Objective Decision Making (MODM) is one of the most widely used
decision techniques in the business and engineering worlds. In the MODM problems, there
are several objectives of the system concurrently optimized, and a solution set, i.e. the
Pareto front, is usually obtained instead of a real optimal solution. This paper explains
in details the combination models of HTSFCL as a component in PSCAD/EMTDC and
presents the optimization algorithm based on a new approach of normalized multi-objective
simulated annealing.
