To better promote the interaction between supply and demand sides，stimulate the potential for demand side response，and fully consider the complex response characteristics of demand side users，a dual-layer optimization model based on a dynamic energy pricing mechanism is proposed.Firstly，the interaction behavior between multiple entities on both sides of supply and demand is considered，and a user dissatisfaction conversion coefficient is introduced.A dynamic energy pricing mechanism that takes into account the factors of user dissatisfaction is established to provide upper-layer dynamic energy prices for a comprehensive dual-layer optimization model.Then，based on the dissatisfaction factors affecting dynamic energy prices，the user dissatisfaction cost is optimized in the lower-layer model to achieve dynamic optimization and regulation of the integrated energy system.Simulation results verify that the proposed optimization model can fully tap into the potential of demand side regulation，and it is effective in promoting the consumption of renewable energy，improving economic efficiency，and meeting user demand satisfaction.
