In order to enable a multi-energy coupling integrated energy system (IES) to meet the needs of load diversity in low-carbon economic operation. a bi-level optimal configuration method for low-carbon economic operation of multi-energy coupling IES in different charging modes of electric vehicles (EVs) is proposed. First. an IES including cold-thermal-electric-gas coupling is established. https://fitnessgravesyardes.shop/product-category/console-wire/
