Abstract
This study focuses on the excess disposal capacity of the calorific potential basis and load shifting capabilities of waste-to-energy （WtE） plants. An electricity supply-demand balance estimation model of one-hour resolutions has been developed: The supply sector consists of a WtE plant and a solar photovoltaic facility with three demand-side buildings comprised of one hospital, one office, and one municipal office. The study specifically analyzes the improved effects of WtE intervention measures on supply-demand balance through operation planning of incinerators over a one-year period, shifting incineration load rates weekly. The results show reductions in both the electricity surplus imbalance and deficit when the supply sector is comprised of a combination of WtE and PV. Additionally, changing operation planning at the WtE shows a significant reduction in surplus electricity during the two months of April and May, when PV output control is assumed. It is clear that a WtE plant has the capacity to adjust supply-demand balance through load shifting on a weekly basis with two furnace operation days being arranged.
