ZERO-CARBON ECONOMIC DISPATCH OF PARK INTEGRATED ENERGY SYSTEM CONSIDERING CARBON CAPTURE AND POWER TO GAS
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.
