Potentiality of Demand Response and Curtailment for Wind Power Integration: Implications for Demand Response Designing

摘要

This study evaluated the degree to which wind power can be integrated in Japan by adopting curtailment and demand response, subject to the ramping capability identified from the hourly electric demand variation, which can be interpreted as a "capability without additional effort" that the utilities are equipped with as aggregated dispatchable power plants. The required curtailment rate, demand response rate, number of demand response events and time of the year of the event were revealed. The results show that the wind power integration potential, which is 10GW and 17TWh without any integration measures, increases as much as to 32GW to 51GW and 57 to 86TWh, equal to the potential yielded by strengthening interregional transmission lines, if 1% to 5% curtailment and demand response with 1% to 5% of the maximum reduction rate are introduced.
