Abstract The Duck Curve phenomenon caused by the volatility of renewable energy hinders the flexibility of grid operation and causes rapid output adjustments of generators. According to the 11th Basic Plan for Electricity Supply and Demand, the proportion of renewable energy is expected to continuously increase, and countermeasures are required. This paper examined the possibility of alleviating the Duck Curve through demand response based on the Time of Use rate system. The demand response potential in Gangwon and Jeonnam regions was applied to PLEXOS simulation to perform a benefit analysis. At this time, there were four load shift scenarios by demand response. Through simulation of each scenario, the benefits were calculated and compared from the perspectives of the country and power companies. This paper performed simulations for 2024 and 2030 and confirmed that load shifting through demand response is an effective means to secure economical grid flexibility without separate ESS investment.
