Abstract:This paper proposes a double‑layer optimal configuration model for household energy storage capacity,which takes the minimum replacement cost and operation cost of energy storage investment as the objective function and takes into account the loss with the battery life. Specifically,the inner model configures the energy storage capacity through optimizing the operational strategy,while the outer model carries out planning for the total operational cost of the system. At the planning stage,the economic and optimal operation of household energy storage users is thoroughly factored in,and related model is established to quantitatively evaluate the loss with the service life of the running battery. The simulation results indicates that this method can significantly reduce the investment cost of household photovoltaic energy storage system and enhance the cost‑effectiveness of household energy consumption.
