Abstract
The ARMA (AutoRegressive Moving Average) model is used to predict the wind power, the multiple linear regression method is used to predict the photovoltaic power, the piece-wise linearization method is used to present the relationship between the fuel cost and output power of MT (MicroTurbine), and a battery model considering the charging/discharging efficiency and states is established. With the minimum internal fuel cost and the minimum electricity purchase cost as the objectives, the control strategy of microgrid operation is optimized by charging and discharging the battery. CPLEX software is applied to solve the optimization function and the results of optimal operation are presented, which show that, with the proposed optimization strategy, the battery is charged when the electricity price is lower while discharged when the electricity price is higher and the operating cost is less than that of the traditional control strategy.
