智慧電網與微電網的概念是將供電端到用電端的所有設備透過感測器連接，形成綿密完整的用電網路，並對其中資訊加以整合分析，以達到電力資源的最佳配置，藉此降低成本、提升可靠性、提高用電效率。而微電網即是智慧電網的縮影，要如何監控與管理微電網裡各項分散式供電系統與負載使用情形勢必為往後電力事業提升能源使用率要探討的議題之ㄧ。
隨著智慧電網與微電網的發展，電力品質監控成為不可或缺的基礎功能。要實現監控電網之電力品質必須具備兩大要素，分別是末端擷取設備與能源管理系統。在末端擷取設備方面目前市場主流是使用搭載ZigBee天線之智慧電表將量測的用電資訊傳送至能源管理系統以提供使用者執行用電品質的監控與管理。
本論文目的在於開發一套能源管理系統監控遠端負載之用電資訊與電力品質狀況，並且結合LabVIEW與搭載ZigBee天線之智慧電表，以完成一整體性的用電行為模式。並配合擷取之用電資訊及LabVIEW相關界面設計，讓使用者以淺顯易懂的視覺化效果瞭解使用之電力品質、用電情況與用電歷史紀錄等資訊。

The concept of smart grid and micro grid is to connect all the devices by sensors from suppliers to consumers, and then the information will be integrated and analyzed. As a result, the power research can be deployed effectively, and it could save energy, reduce costs, increase reliability and power efficiency. Micro grid is a small scale of smart grid. To monitor and control the loads and distributed energy resources in the micro grid, we will discuss issues of increasing the energy efficiency.
According to the development of smart grid and micro grid, maintaining good power quality is an essential function. There are two elements carrying out monitoring and controlling the power quality, such as the end device and energy management system. The end device is smart meter with ZigBee antenna in mainstream market. The information can be transmitted to energy management system for monitoring and controlling.
The purpose of the thesis is building an energy management system for monitoring and controlling remote loads’ power information and for observing power quality. For accomplishing a general power consumption behavior, the thesis integrates smart meter with ZigBee antenna into the system with LabVIEW. According to the received information, designing the interface allow users to immediately realize power quality, power condition, and power record.

Keywords: Smart Grid, Micro Grid, power quality monitor and control, end device, energy management system
