Region-Wise Evaluation of Real-Time Price-Based Demand Response Programs in Japan's Wholesale Electricity Market, Estimating Energy Saving and Avoided Greenhouse Emissions
Beschreibung:
Real-time pricing demand response programs (RTP-DRPs) are practical measures that ensure the end user’s profitability from using electricity by adjusting the supply and demand equilibrium without activating costly solutions. This study explores the potential of RTP-DRPs by developing and applying a region-wise modeling approach based on maximizing the end-users social welfare in the wholesale electricity market in Japan. The regions of the wholesale market are classified based on their response into; regions with excess supply, regions with high demand burden, and regular suppliers of inter-regional connections. The results revealed that, the RTP-DRPs could potentially reduce the peak demand of the residential sector in Chubu, Chugoku, Kansai, Kyushu, Tokyo, and Tohoku by 1.91% to 7.81%. Meanwhile, in Hokkaido, Hokuriku, and Shikoku by 16.13% to 22.9%. The avoided greenhouse emission (GHG) in Tokyo is estimated to be 82.6 and 192.2 tons in summer and winter, respectively
