Thermal power unit combination method considering short circuit ratio constraint

With the increase of the scale of new energy integration, the strength of the power system becomes weak, and the consumption of new energy is limited. It is necessary to reasonably optimize the combination of thermal power units to improve the system strength and new energy consumption capacity. Therefore, this paper analyzes the relationship between the thermal power unit combination mode and the short circuit ratio index. Then, under the premise of satisfying the short circuit ratio constraint, an optimization model of thermal power unit combination mode with the goal of maximizing new energy consumption is proposed. Finally, the effectiveness of the proposed method is verified by the actual typical power grid.
