This paper proposes an environmental economic dispatch strategy for power-gas interconnection system considering spatiotemporal diffusion of air pollutant and P2G in coastal areas. Firstly, considering the complex and changeable meteorological conditions in coastal areas and the regional characteristics of the atmospheric layer, an air pollutant diffusion model considering the local sea-land circulation and thermal inner boundary layer is studied. Then, a multi-objective environmental economic dispatch model is employed, and the economic cost, carbon emission quantities, and pollutant concentration contribution values are set as optimization objectives. Finally, we conduct the optimization with the multi-objective distributed algorithm based on ADMM. Cases study is carried out on IEEE39 power network and Belgium 20 gas network, which validate the effectiveness of the proposed strategy.
