Abstract With the increase in the available types of renewable energy sources, such as wind and solar radiation, it is essential that thermal power plants operate more flexibly in order to stabilize their power system. For practical flexible operation, operators (or designers) need to consider multiple evaluation indicators. This paper proposes a multi-objective evaluation method for plant operation using self-organizing maps and data envelopment analysis. Pareto-optimal solutions extracted from the results of start-up dynamic simulation of a combined cycle power plant verify the efficacy of the proposed method.
