High penetration of variable renewable energy (VRE) systems will impact power system operations because generation of VRE systems depends on weather conditions. We analyzed the operational situation and photovoltaic power yield curtailment for the Tokyo Electric Power Company area in 2030 using day-ahead unit commitment (UC) model when a high penetration of VRE systems is expected. At first, we updated our UC model to optimize PV curtailment keeping power system's security (load frequency control reserve) and minimizing operational cost. Using the updated model, we found that in case of 53GW and 100GW of PV penetration, around 0.34% and 4.83% of PV curtailment would be required throughout the year. High curtailment rate would be required only in spring and autumn seasons when power demand is small and PV yield is large. Regarding the other seasons, high curtailment rate would not be needed in any of the high PV penetration scenarios.
