近年來，分散式能源有著飛躍性的成長，太陽能與風力發電等再生能原滲透率日益提升，分散式能源之互聯性與互操作性受到越來越多關注。為了能確保電網系統正常運行，分散式能源與其他電力設備間的通訊至關重要；因此建立一個電力資訊即時交流的環境成為現在的重要的主題。同時，隨著物聯網技術日趨進步，物聯網的數據交換方式也變得更加靈活，各種中介層軟體的出現，正好呼應了智慧電網通訊上的需求；不過在享受便利的同時也有其隱憂：數據在進行交換時能如何防範外來的入侵干擾、保密我們的資訊，也是個必須考慮的問題。有鑑於此，本論文使用了基於發布與訂閱方式通訊的中介層軟體：資料分散式服務(Data Distribution Service, DDS)；加上AES結合RSA與Hénon Map亂數產生的混合式加密，並將此技術應用於一獨立型微電網，作為電網內發電、負載、控制與儲能設備間的通訊基礎，以鞏固我們的資訊安全，提供一個實踐微電網內互操作性，且具備安全性的環境。

In recent years, distributed energy resources (DERs) have been growing rapidly. The penetration of renewable energies such as solar energy and wind power are increasing, and the interconnection and interoperability of distributed energy resources are getting more and more attention. To ensure the normal operation of the grid system, communication between decentralized energy and other electrical equipment is essential. Therefore, establishing an environment for electric power communication has become an important topic. In the meantime, with the advancement of Internet of Things technology, the means to exchange data through the Internet of Things has become more flexible. The emergence of various middleware meets the needs of smart grid communication. However, while taking advantage of these conveniences, there are also hidden concerns. Such as how to prevent external intrusion interference and keep our information confidential when exchanging is also a problem that must be considered. This thesis proposes a hybrid encryption algorithm using AES, RSA, and Hénon Map pseudo-random number for publish-subscribe middleware, Data Distribution Service (DDS). The combination then is applied to a stand-alone microgrid as the basis for communication between power equipment in the microgrid to enhance our information security and provide a safe communication for interoperability in the microgrid.
