摘要
近年來,智慧家庭能源管理系統的發展日趨重要,藉由智慧家庭能源管理系統讓家庭的角色 從原先單方面的電力消費者轉為電能產消者(Prosumer),或是藉由設置儲能設備轉為產消儲電者 (Prosumager),亦即消費者同時也是生產者,能夠為其自身帶來額外的效益。本研究旨在探討智慧 家庭能源管理系統(Smart Home Energy Management System, SHEMS)的核心價值以及經濟分析,採 用成本有效性分析法,評估案例家庭採用智慧家庭能源管理系統是否具有收益,過程中採用三種模 擬情境。情境一是電能產消者:案例家庭參與台電公司需量反應方案。情境二是電能產消者:案例 家庭參與台電公司需量反應方案,並自行使用部分太陽光電系統之電力,剩餘的電力再將之躉售給 台灣電力公司。情境三是產消儲電者:案例家庭將太陽光電系統電力藉由儲能設備儲存使用並參與 台電公司的需量反應方案,剩餘的電力再將之躉售給台灣電力公司。根據本研究之實證分析顯示, 模擬情境二最符合成本有效性。從案例家庭的觀點,在現行的制度下,將太陽光電系統電力依照躉 售費率銷售給台灣電力公司具有相當大的收益,其原因為目前台灣電力公司之躉售費率金額遠高於 時間電價。本研究透過量化研究,讓未來參與智慧家庭能源管理系統的家庭,有所依據衡量其收 益。

Over the past few years, the development of smart home energy management systems (SHEMS) has become increasingly crucial. SHEMS convert the role of households from a consumer of electricity to a prosumer or—through the installment of energy storage devices—a prosumager of electricity. Specifically, SHEMS equip households with a dual role of a consumer and also a producer, creating additional benefits to consumers. With the aim of discussing the core value of and conducting an economic analysis on SHEMS, this study evaluated the economic benefits of application of SHEMS in the case households with cost-effectiveness analysis. Three simulation scenarios were used in the evaluation as follows: (1) the case households participated in the demand response program of Taipower. (2) Prosumer: the case households used part of the electricity produced by itself, and participated in the demand response program of Taipower, and sold all excessive power to Taipower at the wholesale electricity rate. (3) Prosumager : the case households stored produced electricity in an energy storage device for future use and participated in the demand response program of Taipower and sold all excessive power to Taipower at the wholesale electricity rate. According to the empirical analysis, scenario (2) was determined to be cost-effective. On the basis of the case households and under the existing policy, selling self-produced electricity to Taipower at the wholesale electricity rate generates great economic benefits. This is because the current wholesale electricity rate adopted by Taipower is much higher than the time-of-use rates. Through a quantitative research design, this study provided insights into the economic benefits of SHEMS for households planning to use such a system.
