要約(英語): The larger variable renewable energy (VRE) is introduced, the more adjusting power is required to keep power system frequency. This paper evaluates effects of battery storage system introduction and tie-line capacity enlargement with supply and demand simulation model, considering accurate constraints of adjusting power. Future fluctuations and forecast errors of VRE output are also considered to reflect the required adjusting power, which will increase together with VRE capacity. The simulation model minimizes the annual total costs of power system in 2030 with many hourly constraints in 9 areas in Japan. Results show that battery storage system introduction decreases much of VRE curtailment, whereas tie-line capacity enlargement has limited effects on the curtailment, because battery storage system can supply adjusting power while tie-line power flow can level VRE curtailment across areas. When kWh capacity of battery storage system is constant, the larger ratio of kW/kWh capacity is confirmed to be more effective in reducing VRE curtailment, total cost, and CO2 emission.
