摘要：
To realize the secure，flexible，and low-carbon operation of integrated energy system，an optimal scheduling strategy that considers the low-carbon demand response is proposed. This strategy considers the interaction between source and load sides and conducts research at multi-time scales，including day-ahead and intra-day. Firstly，a hybrid energy hub model is established based on the system structure and multi-energy complementary，incorporating elements of demand response load and energy storage. Then，a demand response strategy is devised for contracted and real-time response loads that possess varying response speeds，and within the system，scheduling information is communicated to attain a low-carbon demand response through interactive means. Finally，the day-ahead optimal scheduling considering the shared cost of carbon emission is implemented，with the aim of achieving the lowest economic cost，the lowest carbon emission，and the highest user comfort. The day-ahead plan guides the performance of intra-day rolling and real-time optimal scheduling. The simulation results indicate that the proposed strategy can efficiently exploit the scheduling potential of both source and load resources，mitigate the accommodation issue of renewable energy，and furnish insights for the economic and low-carbon scheduling of integrated energy systems. © 2024 Science Press.
