Summary: This paper proposes an optimization model for the regional integrated energy system (RIES) that considers multiple uncertainties, multi-energy coupling, and integrated demand response (IDR). The model includes renewable energy, upper grid, coupling devices, energy storage equipment, electric vehicles (EVs), and electrical, heating, and cooling loads. By comparing and analyzing the mathematical characteristics of the uncertainty of sources and loads, the robust optimization (RO) is used to model the uncertainty of sources, and the stochastic optimization (SO) is used to describe the uncertainty of loads. The proposed model is validated with an actual RIES, and the results demonstrate that the RIES model considering multiple uncertainties and multi-energy coupling can effectively ensure the cooperative operation of the RIES and improve its reliability and economy.

Summary: The paper proposes an optimal scheduling model based on CCHP and carbon capture device to achieve the low-carbon operation of the integrated energy system by considering demand response and ladder-type carbon trading mechanism. The model takes into account the demand response of cooling, heating, and electricity load based on time-of-use electricity price and incentive mechanism, and establishes a carbon trading model considering the actual carbon emissions and ladder-type carbon trading mechanism. By solving the mixed integer linear problem using CPLEX, the results show that the system total cost can be reduced by 5.9% with ladder-type carbon trading, and further reduced by 3.1% after considering user-side demand response. The simulation results demonstrate the flexibility of load transfer, reduced gas purchase, and decreased system carbon emissions with the introduction of demand response and ladder-type carbon trading, providing significant application value.

Summary: Coupling renewable energy power generation, electric vehicles, combined cooling heating and power system, and energy storage system is a new way for Community-Integrated Energy Systems (CIES) to shift to a low-carbon, highly efficient, environmentally friendly society. An integrated demand response program is used to explore the potential interaction ability of electricity-gas-heat-cool-Electric Vehicles flexible loads, and a ladder-type carbon trading mechanism is designed. The simulation shows that CIES operation can effectively balance economy and reliability, and EV charging in the CIES has a significant environmental benefit in carbon dioxide emissions reduction.

It established a refined capacity allocation constraint model based on the structural characteristics of the energy demand load and the operation characteristics of each equipment in the IES. An IB optimization model, considering economic, environmental, and energy benefits, was then established. Furthermore, an integrated demand response (IDR) model covering cooling, heating, electricity, and gas was constructed, and its effect on IB was evaluated.
