To achieve carbon neutrality, the proportion of renewable energy must increase according to the 2030 implementation plan. However, the stability of the power supply is reduced owing to the output volatility of renewable energy. To ensure a high power quality, the system must operate stably. Therefore, only as much variable renewable energy as the system can accommodate should be input. In this study, we developed a methodology to calculate the limit input capacity of solar power generation by considering the power generation and transmission systems. For the power generation system, the minimum constraints of power generation capacity and secondary reserve power were considered. Additionally, line capacity constraints were considered for the transmission system. In other words, a methodology was developed to calculate the limit input capacity of solar power generation that satisfies the three constraints.
