To enhance peak-shaving and valley-filling performance in residential microgrids while reducing the costs associated with energy storage systems, this paper selects retired power batteries as the storage solution, breaking through existing optimization models.

Based on the relationship between power and capacity in the process of peak shaving and valley filling, a dynamic economic benefit evaluation model of peak shaving assisted by hundred megawatt-scale electrochemi-cal ESS considering the equivalent life of the.
