Low-carbon optimal dispatch of integrated energy system considering demand response under the tiered carbon trading mechanism

no code implementations4 Oct 2023 Limeng Wang, Xuemeng Liu, Yang Li, Duo Chang, Xing Ren

The example results show that considering the carbon trading cost and demand response under the tiered carbon trading mechanism, the total operating cost of IES is reduced by 5. 69% and the carbon emission is reduced by 17. 06%, which significantly improves the reliability, economy and low carbon performance of IES.
