The outstanding photovoltaic (PV) abandonment problem can be effectively solved by configuring energy storage (ES). The capacity configuration and operation control strategy of ES are the main difficulty in the economic operation of the system. In this paper, a comprehensive evaluation model is established to evaluate the economics of ES to improve PV consumption. Further, an ES capacity configuration method based on double-layer optimization is proposed. The upper optimization uses PV curtailment rate to determine the feasible region of ES capacity configuration. The comprehensive economic benefits are used as the inner optimization indicator to optimize the capacity configuration of ES. The ES charging and discharging strategy used in the paper can realize the efficient use of PV power. The simulation result proves the effectiveness of the proposed method.
