Does capacity configuration optimization improve the stability of microgrids?
To improve the accuracy of capacity configuration of ES and the stability of microgrids, this study proposes a capacity configuration optimization model of ES for the microgrid, considering source–load prediction uncertainty and demand response (DR). First, a microgrid, including electric vehicles, is constructed.
What factors affect the configuration of energy storage in microgrids?
The fluctuation of renewable energy resources and the uncertainty of demand-side loads affect the accuracy of the configuration of energy storage (ES) in microgrids. High peak-to-valley differences on the load side also affect the stable operation of the microgrid.
How is battery energy storage sizing a microgrid?
A novel formulation for the battery energy storage (BES) sizing of a microgrid considering the BES service life and capacity degradation is proposed. The BES service life is decomposed to cycle life and float life. The optimal BES depth of discharge considering the cycle life and performance of the BES is determined.
Does es capacity and Dr reduce the cost of a microgrid?
The simulation results show that the optimal configuration of ES capacity and DR promotes renewable energy consumption and achieves peak shaving and valley filling, which reduces the total daily cost of the microgrid by 22%. Meanwhile, the DR model proposed in this paper has the best optimization results compared with a single type of the DR model.
Do peak-to-valley differences affect the stability of a microgrid?
High peak-to-valley differences on the load side also affect the stable operation of the microgrid. To improve the accuracy of capacity configuration of ES and the stability of microgrids, this study proposes a capacity configuration optimization model of ES for the microgrid, considering source–load prediction uncertainty and demand response (DR).
