The proposal of "double carbon" (carbon peak and carbon neutrality) goal provides strategic guidance for future energy transition. With the large-scale grid connection of distributed clean energy and the diversification of energy consumption in demand side, the low-carbon and economical optimal operation strategy of virtual power plant considering carbon emission and multi-energy response of demand side has become a key problem to be solved. Based on the background that virtual power plants participate in energy market transactions by means of integrated demand response, this paper establishes a two-stage optimal operation model of virtual power plants, which comprehensively considers distributed clean energy, comprehensive energy storage equipment, energy conversion equipment, market energy transaction, integrated demand response and carbon emission. The first stage is a low-carbon and economical operation model of virtual power plant considering carbon emission cost. The second stage is an integrated demand response model based on bi-level programming. Solution methodologies of each stage model are given. Finally, simulation results show that the proposed model is not only conducive to reducing the carbon emission cost and total scheduling cost of virtual power plant, but also helpful to improve the benefits of users participating in integrated demand response, realizing a win-win situation between virtual power plant and users.
