The application discloses a new energy coupling type combined heat and power system and belongs to the technical field of distributed energy and combined heat and power. The system comprises a renewable energy power generation unit, a solar light and heat unit, a high-temperature heat storage unit, a biomass heat source unit, a steam generation and mixing device, a back pressure steam turbine generator unit, an electric heating and heat storage unit and a control unit. Solar heat collection heat is directly supplied to a steam generator through heat conduction oil or stored in a double-tank molten salt heat storage system, heat storage and heat release can supplement insufficient biomass steam, and the excess wind and light power drives a heat pump to heat and store heat, indirectly participates in steam circulation and realizes deep coupling of electricity-heat-steam cross media. The control unit adopts a hierarchical model predictive control to globally coordinate. The application greatly reduces the renewable energy power abandonment rate, guarantees continuous and stable operation of a steam turbine, flexibly adjusts a heat and power ratio in a range of 0.3-1.5 and significantly improves comprehensive energy utilization efficiency.
