The invention discloses an electric energy replacement policy simulation technology based on renewable energy subsidy distribution, and belongs to the technical field of electric energy replacement policy simulation. Aiming at the current situation that a support policy of electric energy substitution and renewable energy interaction in China lacks quantitative technical support, a growth model containing a renewable department and a non-renewable department is constructed, and an incentive policy capable of guiding electric energy substitution customers to select renewable energy is formed; based on the electricity purchasing behavior of the user under the renewable energy subsidy distribution policy, the influence of the electric energy replacement policy on economic development and ecological environment is calculated, the user is stimulated and guided to actively select the electric energy, the high-pollution and low-efficiency energy using mode is eliminated, and meanwhile important auxiliary support is provided for policy analysis, comparison and decision making of a policy decision maker.
