Performance of energy community and DGSs in centralized and hierarchical cases.

	Self-sufficiency rate (%)	Self-consumption rate (%)	Total operating cost (K$)	CO2 emission (t)
Centralized case	69.31	63.17	61.94	678.19
Distributed case (relative variation)	67.20 (−3.04%)	61.25 (−3.04%)	63.96 (3.26%)	724.69 (6.86%)
