Against the backdrop of the “dual carbon” goals, the efficient, flexible operation and zero-carbon transformation of integrated energy parks are of paramount importance. Integrated energy parks utilize energy coupling equipment such as combined heat and power units and electric boilers to achieve flexible energy supply. By introducing carbon emission costs and green certificate purchase costs into the electricity price, a new power supply pricing mechanism is constructed. This can effectively guide the parks to adjust their energy supply behavior and promote the overall realization of zero-carbon operation. This paper proposes a zero-carbon operation method for integrated energy parks based on a distributed collaborative strategy, characterized by the park’s energy management center dynamically adjusting electricity prices using carbon emission and green certificate costs to achieve zero-carbon operation across multiple integrated energy parks. Simulation results show that the proposed strategy can assist integrated energy parks in gradually achieving zero-carbon operation, providing theoretical support and practical reference for the low-carbon transformation of the energy system.
