This paper presents a robust regret optimal scheduling method for microgrid to suppress disturbance from uncertainty of PV output and load demand. According to predicted value of uncertainties and time-of-use price, a dynamic time division method is developed to reduce model solving complexity. Wastage of battery cycle life under different depth of charging and discharging is considered. Meanwhile, a robust regret optimal scheduling model for microgrid is established. Considering that the proposed model is ...
