Abstract

Highlights: A co-optimization method for in nearly-zero energy community supply system was proposed. The effect of the electric vehicle number on the overall benefit of the system was analyzed. The zero-carbon zero-energy potential of the nearly-zero energy community supply system was studied. The system's carbon emission and energy consumption were 30.4 kWh/m 2 and 6.9 kg/m 2, respectively. Abstract: As a typical representative of a green and low-carbon community, a nearly-zero energy community is the main development direction of future building forms. Therefore, to improve the proportion of renewable energy and reduce primary energy consumption and carbon emissions, this paper constructed a nearly-zero energy community supply system, including the battery, heat storage tank, and cold storage tank. A multi-parameter collaborative optimization model considering system design and operation was established to improve the economy, energy-saving, and carbon-abatement potential of the system. This paper took a nearly-zero energy community to study the influence of different electric vehicle numbers on typical daily energy balance, energy-saving, and carbon-abatement potential of the nearly-zero energy community supply system. The results showed that when the number of electric vehicles increased from 0 to 600, the zero energy potential, primary energy saving rate, and carbon emission reduction rate of the nearly-zero energy community supply system decreased by 6.8%, 2.6%, and 1.8%, respectively. The cost per unit supply area increased by 7.8CNY/m 2, and the annual cost saving rate increased by 29.7%. The system's optimization design method and energy-saving and carbon-abatement potential evaluation result provided a valuable reference for the integrated building and transportation sector development.
