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: This study investigates the role and current situation of Low-Carbon Technology (LCT) in achieving urban Carbon Neutrality goals and Sustainable Urban Development (SUD). It focuses on three aspects: new energy-supported LCTs, building-oriented Energy Conservation and Emission Reduction (ECER), and Carbon Capture, Storage, and Utilization (CCSU) technology. A review of the past ten years' research is conducted, selecting over 20,000 articles and analyzing more than 150 papers with high citation rates and novel research results. Case studies are also conducted to explore urban green development and building energy conservation solutions. Suggestions are provided for achieving SUD. The importance of controlling emissions from building energy consumption is emphasized, as it is a significant carbon emitter.

Summary: This study constructed a two-stage optimization model to explore the influencing factors of the integrated benefit (IB) index of integrated energy systems (IESs) and the best energy supply mode. 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.

Summary: A scheduling model for hybrid energy generation system (HEGS) trading in both day-ahead electricity and hydrogen markets is proposed to maximize total profits based on price arbitrage. The HEGS is based on a real case in Southwest China and includes three hydro units, two photovoltaic plants, a pumped-storage facility, and an electrolyzer. The model is cast as an adaptive robust optimization (ARO) model, and the column-and-constraint generation algorithm is employed to solve it. The numerical results show that HEGS trading in two markets can increase total profits compared to trading in the electricity market only. The total profit is also significantly affected by the uncertainty budget and robustness.
