FBWM-MARCOS based planning method for grid peak-frequency regulation energy storage system

The selection of energy storage systems is crucial for effective participation in grid frequency modulation (FM) and frequency deviation (FD) planning. This study proposes a methodology integrating the Fuzzy Best-Worst Method (FBWM) and MARCOS to evaluate the applicability of energy storage technologies. Expert scoring and FBWM are employed for weight determination, with fuzzy theory mitigating uncertainties in expert judgment. MARCOS is then used to compute the overall evaluation scores. This approach provides a theoretical foundation for energy storage planning in grid regulation and holds significant engineering applicability.
