    Abstract: 交流微電網的電能調度為一最佳化的問題,必須在所設定的限制條件下最小成本的運轉。本文使用混合整數線性規劃法(Mixed Integer Linear Programming, MILP)的方式來描述問題模型,然後採用最佳化求解軟體CPLEX來建立微型電網系統模型並求解。本文以國內核能研究所建構之微型電網示範系統為參考系統,考慮風力發電與太陽能發電系統之發電量,來最佳化微型渦輪機與儲能設備之運轉調度。 為了提高微電網運轉時頻率的穩定度,本文使用下垂控制及虛擬慣性來做為最佳化中的限制條件來調節微電網運轉時的頻率。最後再各種案例顯示,在孤島及併網模式下,得以用頻率調節限制及卸載機制來符合台電規定的標準。
    An AC Microgrid dispatch is an optimal problem, it must operate at the minimum cost under the set restriction conditions. This thesis uses mixed integer linear programming (MILP)-based model for microgrid power dispatch, and then use the commercial software CPLEX to create a microgrid system model and solve the optimal problem. The microgrid demonstration system implemental by Institute of Nuclear Energy Research (INER) is selected as a demonstration system. The operation scheduling optimization of microturbines and energy storage devices effectively coordinates with wind power and solar photovoltaic system. In order to improve the frequency stability in microgrid, the constraints of droop control and virtual inertia are used to regulate system frequency. Finally, a variety of cases show that in the islanded and the grid-connected mode, it can use constraints of the frequency regulation and shedding to meet the requirements of Taipower standards.
