電力公司透過需求回應程式(Demand Response Program)告知價格及金錢獎勵的資訊給用戶端的裝置，降低尖峰時段用電，並減少電力公司在尖峰時段發電成本。其中用戶端的裝置，包括負荷控制裝置、智能恆溫器以及家庭能源控制台。
為了創造用電戶與電力公司雙贏的局面，因而提出用電延遲的機制，並應用於智慧電網的環境中。並設計模擬模型驗證此機制，是否有效將尖峰時段用電移到離峰時段。探討模擬實驗中加入此機制，各種環境參數的設定，對效能的影響。本篇論文中，加入此機制降低尖峰時段用電，讓電力公司的發電成本降低，並降低使用者花費的總用電成本。

Demand Response (DR) program allows utilities to inform customers about the information through the devices from customer side. For utilities, DR program reduces the cost of generation electricity during peak time by offering the profit to customers. Such devices include load control devices, smart thermostats and home energy consoles. DR program provides pricing information and monetary incentives.
Expect to create a Win-Win situation for customers and utilities. We devise a deferred mechanism in SG (Smart Grid) which can shift demand to non-peak time. Then, we develop a simulation model to evaluate the mechanism. Finally, we use simulation experiments to discuss the performances in detail of each figure. In this thesis, with this mechanism reduces generation cost of utilities during peak time and also customers can spend less price to use electricity.
