To improve wind power accommodation rate and the economy of system operation, a multi-time scale source-grid-load-storage coordinated scheduling strategy that considers the life loss of hybrid energy storage is proposed. Firstly, based on the differential degradation mechanisms of lithium-ion batteries and all-vanadium flow batteries, a battery cycle life loss model accounting for depth of discharge is established to quantify the cost of energy storage life degradation. Secondly, combined with the regulatory characteristics of demand response resources on the load side, through the collaborative optimization of day-ahead scheduling plans and intraday rolling adjustments,an optimal operation model of source-grid-load-storage is built, with the goal of minimizing the total system operating cost and wind curtailment cost. Finally, the results of the modified IEEE-30 bus case study show that the proposed strategy can effectively reduce the cost of energy storage life loss, improve the wind power accommodation rate, and significantly decrease the total system operating cost.
