In this thesis an approach for solving various optimization problems in area of electrical power network elements is presented. Results and details of optimization algorithm applications for solving various elements, such as transformer, post composite insulator, gas discharge arrester, bushing and network configuration problem are also given. Well known evolutionary algorithm, Differential evolution, has been selected as a fundamental optimization technique. Its downside, which is common to all Evolutionary algorithms, is the required large number of iterations, respectively the number of function evaluations in order to achieve the convergence. To improve this property of Differential evolution algorithm, one has been extended to use Kriging interpolation method. Newly developed Kriging-assisteddifferential evolution algorithm enables the reduction of required function calls. Experiments, which had been conducted on several standard test functions, and also on a real engineering problem, have shown that new algorithm, compared to original Differential evolution algorithm, generally reduces a number of actual function calls by half.
