Abstract: In this paper, we propose an energy management system (EMS) with electric power dispatching and optimization management mechanism that’s different from other references which using load-shedding and optimal power scheduling method. Our proposed system prioritizes the positive value of profit within a period of time and provides the optimized data of power usage to the users for having the maximum profit. Firstly, EMS collects data from the database and process energy dispatching according to the simulated result of different season conditions in one year and the corresponding power price of Taiwan Power Company (Taipower). Then, the trading amount with the power grid is regulated to ensure the user’s maximum profit. On the EMS dispatching interface, while adjusting the imbalance state of power generated, the trading amount with the power grid is regulated based on the condition of battery storage system. Then, the amount of power generated from every hour, every day and every month are analyzed by EMS to determine which period of time have the largest price difference between the supply and demand. Based on the result after analyzing supply and demand, EMS adjusts the data of the supply and battery storage system then makes an annotation of the analyzed data.
