Under the background of"Carbon Peaking and Carbon Neutrality",the operation mechanism of the electric-carbon combined market will become an important practice path for China to deeply explore low-carbon cycle development.With the gradual standardization and refinement of the development of the energy industry,it is urgent to conduct low-carbon research on micro-energy grids.On the basis of industrial micro-energy grid system,with carbon trading costs,carbon tax costs and comprehensive demand re-sponse subsidies taken into account,an optimal dispatch model of micro-energy grid considering comprehensive demand response un-der the combination mechanism of carbon trading and carbon tax is constructed,to maximize the benefits of micro-energy grids,thus the low-carbon economic dispatch of micro-energy grid is realized.
