Abstract

Aiming at problems of multi-energy coupling and zero-carbon operation of park integrated energy systems, this paper proposes a zero-carbon economic dispatch strategy of integrated energy system of the park considering carbon capture and power-to-gas. Firstly, we analyze the architecture of the park integrated energy system to establish a comprehensive model that takes into account carbon capture and P2G coupled with electricity, heat, cooling and gas. Secondly, we conduct a comprehensive calculation of the park's ecological carbon sinks, energy production carbon sources, and other related factors. Zero-carbon indicators were proposed for the system, and an economic dispatch model was developed to maximize its economic benefits. Finally, based on three scenarios： economic dispatch ignoring carbon neutrality constraints, economic dispatch considering carbon neutrality constraints and economic dispatch considering CCUS-P2G joint operation, The improved particle swarm algorithm is used to solve the model combining time-of-use electricity prices. The results verify the effectiveness of the model and method proposed in this paper. Economic dispatch considering CCUS-P2G joint operation can improve clean energy absorption rates, reduce operating costs of the system, and achieve carbon neutrality in the park.
