近年國內工商業持續成長,加上受到全球暖化的影響,夏季的空調用電急遽增加,造成夏季供電不足,急需降低夏季空調用電,為此台電公司提出了空調週期性暫停用電措施,為降低夏季用電尖峰期間的空調用電,但因為負載控制權在客戶手中,且沒有罰則的約束導致措施執行率不如預期。 本研究利用LoRa通訊技術,取其長距離、低功耗的特性,實現長距離範圍的通訊,透過Arduino嵌入式開發系統讀取電子式電表所收集之用電狀況,並使用LoRa無線通訊模組將資料發送至網路,取代人工抄表,同時也把歷史數據儲存至裝置於Raspberry Pi 上的Node-RED資料庫當中以提供日後查詢與分析。 電力公司可在用電尖峰期間或電力需要調度時,利用本研究的Node-RED人機介面發送MQTT控制指令,直接對客戶的空調設備實施空調週期性暫停用電措施,提升措施的執行率。
This study uses LoRa communication technology, takes its long-distance, low power consumption characteristics, realizes long-distance communication, reads the electricity status collected by the electronic meter through the Arduino embedded development system, and uses the LoRa wireless communication module. The data is sent to the network instead of manual meter reading, and historical data is also stored in the Node-RED database installed on the Raspberry Pi to provide future inquiry and analysis. The power companies and users can use the Node-RED man-machine interface to send MQTT control instructions to implement air conditioning periodic power-suspension measures to specified air-conditioning equipment during the implementation of the demand response measures or when the power needs to be scheduled.
