Embodiment
[0060] Embodiment: In this embodiment, an energy optimization method considering battery attenuation cost in a microgrid, such as figure 1 shown, including the following steps:
[0061] Step 1. Build a battery decay cost model: C batt (t), that is, the attenuation expenditure of the battery at time t.
[0062] Step 2: Build a cost model for electricity expenses: T elec (t)*p grid (t), where T elec (t) represents the electricity price at time t, p grid (t) indicates the amount of power exchange with the main grid at time t. If it is a positive number, it means that the user purchases electricity from the main grid, and if it is negative, it means that the user sells it to the main grid.
[0063] Step 3. Establishing the objective function for microgrid system operation optimization: Combining steps 1 and 2, an optimization objective function that minimizes a day’s electricity expenses and battery attenuation costs in the microgrid can be established. The optimization objec...
