Abstract In this paper, we propose a new method to analyze how much surplus renewable energy will occur in what pattern. The difference from existing analysis methods is that seasonal surplus renewable energy patterns can be analyzed. A case study was conducted based on the carbon neutrality scenario in 2050, and it was found that 513.9[TWh] of surplus power was generated. This is because the proportion of solar power generation facilities in Korea's carbon-neutral scenario is very high at 85%, so the trend of generation of surplus power varies depending on the change in the amount of solar power generation. From the perspective of planning a renewable energy-oriented electrical grid, it is very important to rationally predict the amount of surplus power generated in the mid to long term and establish technical alternatives to minimize surplus power. In particular, in the case of mid- to long-term energy storage and power conversion (P2X) technology that needs to consider seasonal characteristics, such seasonal surplus power generation characteristics can be very important information.
