Risk Management of Integrated Energy System Decarbonization

The integrated energy system (IES) enables the fulfillment of load demand through multi-energy flow coupling and enhances energy utilization efficiency. Given the uncertainties posed by the “dual carbon” context, studying the low-carbon economic operation of the IES has become increasingly crucial. To enhance energy efficiency and reduce carbon emissions, this paper proposes and constructs an IES that incorporates electric, gas, thermal, and hydrogen coupling. To account for the environmental variability and risks affecting renewable energy sources, which can impact the IES, the multiple-scene generation and reduction method is introduced to optimize the deterministic IES model. Additionally, carbon capture equipment is integrated into the model, and the validity of the proposed model is verified under various operating conditions. Subsequently, both the economic and environmental benefits of the system are notably improved.
