當今世界各國為了減少工業活動對地球環境的影響，提出減碳政 策，再生能源為其中一環，而微電網的發展與再生能源息息相關，如 何使微電網在兼顧環保節能與用戶成本的情況下運作，是相當重要的 議題；本論文首先介紹微電網運轉模式與電力設備，由於再生能源無 法作為穩定電力來源，需要結合儲能電池系統才能有效改善此情況， 微電網的運作得面臨各種情境，因此調度目標及策略的制定十分關鍵， 本研究考量微電網運轉成本與碳稅為目標，以通過相互準則關聯性得 出準則重要性的方法分配各目標權重定義目標函式，再以螢火蟲演算 法和粒子群最佳化法作為調度策略，並且使用 Matlab 進行模擬調度， 結果顯示提出的策略能夠提升微電網能源使用效率且降低運轉成本 及碳排放；在實際調度中，透過 Modbus 通訊協定結合 C 語言撰寫演 算法，並於中央大學微電網場域驗證調度策略的可行性；最後探討未 來研究可以朝增加電力設備與調度目標為方向。;In today′s world, countries around the globe propose carbon reduction policies to mitigate the impact of industrial activities on the Earth′s environment. Renewable energy is a crucial component of these policies, and the development of microgrids is closely linked to renewable energy. How to operate microgrids while balancing environmental conservation, energy efficiency, and user costs is a significant issue. This paper first introduces the operation mode and power equipment of microgrids. Since renewable energy cannot serve as a stable power source, it needs to be combined with battery energy storage systems to effectively improve this situation. The operation of microgrids needs to face various scenarios, so the formulation of dispatching objectives and strategies is crucial. In this study, considering the objectives of microgrid operation costs and carbon taxes, a method of criteria importance though intercriteria correlation is used to allocate weights to each objective and redefine the objective function. The firefly algorithm and particle swarm optimization are then used as dispatching strategies, and Matlab is used for simulation dispatching. The results show that the proposed strategies can improve the III energy utilization efficiency of microgrids and reduce operation costs and carbon emissions. In practical scheduling, algorithms are written in C language and combined with the Modbus communication protocol to verify the feasibility of dispatch strategies in the microgrid field of National Central University. Finally, future research directions focus on increasing power equipment and dispatching objectives are discussed.
