Electric vehicle aggregators (EVA) that participate in Chinese certified emission reduction (CCER) projects in response to low-carbon dispatching can enhance efficient EVA operation while supporting the low-carbon transition of power systems. To achieve this, a multi-market EVA operational strategy considering electricity-carbon demand response is proposed. First, based on carbon emission flow theory, an EVA energy consumption carbon emission model is constructed based on the dynamic electricity carbon emission factors, and an EVA “electricity-carbon” market benefit model considering electricity-carbon demand response is developed. Next, a game model between market operators and EVAs is established. The upper layer represents the market clearing process, where electricity market operators minimize energy consumption costs, clear the market, and publish clearing results and dynamic electricity carbon emission factors. The lower layer is the EVA market bidding decision-making process, where EVAs formulate energy consumption bidding strategies to maximize their benefits according to the market clearing results and dynamic electricity carbon emission factors. Finally, the effectiveness of the proposed strategy is verified by a numerical example.
