設備運轉之智慧型節能：以智慧電表及情境使用行為探勘為基礎之動態能源配置

Abstract

智慧電表為一新興設備，其被用於蒐集及監測設備之能源消耗數據。使用者可經由監測設備使用情形進行設備運轉狀態之調整，進而達到節能省電之目標。為避免能源浪費，設定能源使用限制，並在其限制下進行能源監控與配置是重要的課題。然而，目前智慧電表系統之研究並未針對此議題進行探討，相關研究僅只提供設備使用統計資訊，並無針對使用者之設備使用紀錄進行深入分析，無法經由預測使用者之使用行為進行能源有效配置及使用。有鑑於此，本研究提出一智慧節能系統，可藉由預測設備使用情形來自動監測與調整設備運轉狀態，進而達成在能源使用限制下有效使用能源之目標。所建構的智慧節能系統主要是以情境探勘分析預測使用者在特定情境之設備使用行為，並進而預先配置電量能源需求給予高重要性設備。此外，系統經由智慧電表偵測設備使用狀態，並進行動態設備能源消耗量監控與能源資源配置。系統會給予設備運轉一電量需求值，確保其能正常運作。當可用能源低於一限值，系統將會自動調整設備運轉狀態，釋出低重要性及閒置設備之可用能源，以增加系統之總可用能源，確保高重要性設備能夠正常運作。此智慧節能系統以資料探勘方法分析情境使用行為，並有效地監測及使用設備能源，達成智慧型節能之目標。

Smart meter is an emerging appliance which can be used to collect and monitor devices’ power consumption usage data. Users can monitor devices’ usage conditions in order to adjust device operations for energy saving. To avoid the power wasting problem, it is an important issue to set a power usage constraint to effectively monitor and control users’ power consumption usages within a restricted power usage range. However, existing researches on smart-metering systems do not address such issue. Moreover, the existing smart-metering systems only derive the statistical information of device usages, rather than conduct further analysis on users’ device usage records for effective allocation and utilization of power usage resources. In this study, a novel Intelligent Energy Saving (IES) system is proposed to effectively monitor and utilize the power usages of devices under the power consumption constraint. The IES system conducts context-based mining to discover device usage patterns in certain context from historical device usage records. Based on the context-based device usage patterns, the system will allocate required power usages to possible device operations in advance. The IES system uses smart-meters to dynamically monitor the power consumption usages of devices and allocate power usage resources to devices. When power usage resources may be insufficient under the power consumption constraint, the IES system will adjust device operations for energy saving to increase available power usages by releasing the unused power usages of low-priority or idling devices to the system. The proposed IES system provides intelligent analysis of context-based usage behaviors, effective monitoring and utilization of power usages of devices for intelligent energy saving.
