Abstract：The near-zero energy community load is predicted and the near-zero energy community energy supply system with multiple energy storage is constructed.For this system,a two-level iterative collaborative optimization method is proposed to optimize the system configuration and operation.The system is used to supply energy to near-zero energy communities with different public building percentages,and to realize thermoelectric storage for community energy supply.The system is comprehensively evaluated in terms of energy efficiency,economic efficiency,and environmental efficiency.The results show that the primary energy saving rate and annual value saving rate of the new system can reach up to 51.1%and 18.8%,when supplying energy to near-zero energy communities with 30%of public buildings compared with the sub-supply system.The supply system with 50%of public buildings achieves the highest comprehensive evaluation value of 0.357 3.
