Performance assessment of evolutionary algorithms in power system optimization problems RuedaJose L. ErlichIstvan Gonzalez-LongattFrancisco 2016 Due to the stochastic nature, there are several concerns on the effectiveness and robustness of evolutionary algorithms when applied to solve different kinds of optimization problems in power systems field. To address this issue, this paper provides a comparative analysis of several evolutionary algorithms based on parametric and non-parametric statistical tests. Numerical examples are based on hydrothermal system operation and transmission pricing optimization problems.
