The invention discloses a low-carbon economic dispatching method for an
integrated energy system containing P2G and
energy storage, and the method comprises the steps: introducing a power-to-gas equipment operation mechanism and a carbon transaction mechanism into an
integrated energy system model of a multi-
energy coupling unit, so as to reduce the operation cost of the
integrated energy system. The method comprises the following steps: firstly, comprehensively considering the characteristics of each unit in an integrated
energy system, constructing a regional integrated
energy system joint scheduling structure comprising power-to-gas equipment P2G,
energy source equipment, storage equipment and conversion equipment, analyzing the working mechanism of the power-to-gas equipment P2G, and establishing a carbon
transaction model of the power-to-gas equipment P2G; secondly, establishing an integrated
energy system optimization
operation model considering the carbon transaction cost by taking
system operation profit maximization as a target; and finally, verifying that the proposed model participates in the carbon trading market through
simulation cases, so that the economic cost of the
system can be reduced, the dependence of the comprehensive energy
system on the external market is reduced, and the feasibility and economy are relatively high.
