摘要：
Under the double carbon target，integrated energy system（IES）integrates multiple energy sources，which is of great significance to promote low-carbon power industry. In order to further improve the environmental protection of IES，this paper proposes a low-carbon economic optimal scheduling model of integrated energy system，which takes into account the carbon trading and the source load side resources. Firstly，a concentrating solar power（CSP）power station is introduced from the source side as a cogeneration unit. Secondly，according to the different transmission properties of electric energy and thermal energy on the load side，the price type demand response model and the heat load demand response model considering the thermal inertia and fuzziness of the heating system are adopted respectively. Then，by introducing the ladder carbon trading mechanism，the carbon emission cost model including P2G device is constructed. Finally，taking the minimum operating cost，carbon transaction cost and penalty cost of wind and light abandonment as the objective function，the IES low- carbon economic optimization model is established. By setting up four scenarios for simulation analysis，after comprehensive consideration of CSP power station，comprehensive demand response and stepped carbon trading mechanism，the system outsourcing cost，carbon emissions and wind and light abandonment rate can be reduced by 25.65%，14.36% and 21.54% respectively，which verifies the effectiveness of the proposed model. © 2023 Science Press.
