Low-Carbon Economy Optimization Operation of Cold-Heat-Electricity Integrated Energy System Based on Digital Twin

The integrated energy system can promote carbon emission reduction by using its multi-energy complementary advantages. So as to diminish the carbon emission of IES, an optimal operation model of IES with the improvement of carbon trading mechanism is proposed. The digital twin technology can link the real world and the digital world. Because the genuine IES is often more complex, based on the digital twin environment, it is convenient to simulate and optimize the different states of the system, which has important reference value for IES. In digital twin environment, the tiered carbon trading mechanism is lead into the model. Considering the low-carbon and economy of the system, the low-carbon economy optimization operation model of the cold-heat-electricity integrated energy system is established. It is verified that the tiered carbon trading mechanism performs better than the constant carbon trading mechanism, while still ensuring the economy of IES.
