摘要

在高科技進步的時代，空調已成為人們生活與工作的一部分。而為了使生活品質、工作效率的提升，必須仰賴空調的便利。由於夏季使用空調頻繁，用電量亦大幅提高。故台電公司為了抑低尖峰用電量，請用戶為配合電力公司抑低用電時，一般以直接負載控制來降低空調負載，雖可達到簽訂契約容量之成效，但卻造成室內區域產生不舒適的情況。
本研究透過建築能源管理系統之需量控制策略，執行需量卸載控制，以四個研究案例來驗證灰色理論預測空調負載準確度，而空調負載實際與預測值平均誤差率為2.41%。研究進行四次卸載實驗，在夏季尖峰用電時段將PMV維持至0~0.5與PPD=5~10的舒適範圍內，並應用灰色理論來預測實驗當日空調負載與需量卸載後實際空調負載做對照比較。
本文考慮以不影響舒適度前提下，來預測空調系統負載在夏季尖峰用電時的可卸載量，進而決定來調控其他電力設備以補足與電力公司所簽訂的「最低抑低契約容量」。

Air-conditioning has become a part of people’s daily life as well as work in high technology era nowadays. To improve life quality and working efficiency, we must rely on the convenient of air-conditioning. Since air-conditioning system is used frequently during summer, the electricity consumption increase substantially. To reach minimum suppression of peak electricity consumption, Taiwan Power Company hope consumers can be cooperated to minimize suppression of electricity consumption. They usually reduce the load of HVAC system by direct load control, although it can reach the contract capacity, but it may cause uncomfortable in indoor area.
This study carried out load-shedding control through demand control strategy of BEMS by using 4 cases to verify the accuracy of applying grey theory to forecast the load of HVAC system. The result shown that the mean error between actual value and forecast value is 2.41%. This study performed 4 load-shedding experiment, to maintain the indoor thermal comfort to an comfortable range that PMV was between 0~0.5 and PPD was between 5~10 in summer peak demand period. This study also applied grey theory to predict the load of HVAC system of a building and compared with the actual load during experiment.
This study consider the premise of not to affect indoor thermal comfort to forecast the possible load-shedding of HVAC system during summer peak. Thereby determining to adjust other electrical equipment to reach the “minimum suppression contract capacity” that signed with the power company.
