EVALUATION OF PV-BT-EV LINKAGE IN HOUSEHOLDS AND EXPANDED ESTIMATION OF THESE SYSTEMS AT THE CITY LEVEL

Abstract

 In this study, seven household models were set up and were evaluated the possibility of power supply and demand adjustment, CO₂ emissions, and costs for each household regarding the effects of introducing and linking PV, BT, and EV. To compare the pre-introduction and post-introduction case, 5 cases were set up: “pre-introduction case”, “PV-only introduction case (PV only)”, “PV and BT introduction case (PV, BT)”, “PV and EV introduction but without V2B (PV, EV)”, and “PV and EV introduction with V2B (V2B)”. As a result, it was found that "V2H" followed by "PV, EV" had a large reduction effect on CO₂ emissions. In addition, the effect on the entire city was evaluated by conducting an extended estimation based on the number of households by type for the city of Kitakyushu. As a result, it was found that the introduction of V2H has the effect of reducing the CO₂ emissions of the residential sector in the entire city by approximately 25%.
