Embodiment 1
[0100] Embodiment 1 The discretization method of conditional discretization is adopted, and the evaluation index scoring reference table is used as a reference to score each index parameter.
[0101] Step S01, obtaining evaluation index sets of a plurality of target systems.
[0102] It is known that the seven types of batteries that need to be evaluated this time are {lead-acid batteries, lithium-ion batteries, nickel-metal hydride batteries, zinc-air batteries, sodium-sulfur batteries, all-vanadium redox flow batteries, and zinc-nickel batteries} for peak shaving and valley filling. {Energy efficiency, energy density, power density, nominal voltage, number of cycles, self-discharge rate, cost per unit of electricity, environmental factors, safety, minimum operating temperature, depth of discharge} a total of 11 evaluation indicators for scoring, used for bidding When choosing a reference for energy storage system.
[0103] Step S02, based on the evaluation index set, obtain...
Embodiment 2
[0145] The two-level discretization used in the second embodiment is discretization. The scoring method for each index is to take the maximum value of the parameter of the i-th index as full marks and the minimum value as zero points, and the remaining parameters are distributed between zero points and full marks in proportion.
[0146] Step S01, obtaining evaluation index sets of a plurality of target systems.
[0147] It is known that the seven types of batteries that need to be evaluated this time are {lead-acid batteries, lithium-ion batteries, nickel-metal hydride batteries, zinc-air batteries, sodium-sulfur batteries, all-vanadium redox flow batteries, and zinc-nickel batteries} for peak shaving and valley filling. {Energy efficiency, energy density, power density, nominal voltage, number of cycles, self-discharge rate, cost per unit of electricity, environmental factors, safety, minimum operating temperature, depth of discharge} a total of 11 evaluation indicators for sc...
