With the proposal of the double carbon target and the promotion of the distributed photovoltaic policy of the whole county, the balance between development and the environment needs to be paid more and more attention. The study of the ecopark model and greenhouse technology is an effective way to balance development and the environment. Firstly, the typical energy scenarios of smart greenhouses are analyzed, and the main problems faced by greenhouses in the emergence stage are mentioned.Secondly, the influence of photovoltaic policies on the energy supply mode of the whole county is proposed, and the significance of the change of energy supply mode is analyzed. Thirdly, in view of the problem of local consumption of renewable energy, the energy supply mode of“production-use-storage”integrating the main energy- using equipment of the greenhouse is proposed, and the platform framework and basic functions based on the control of the Internet of Things are designed. Finally, by using the photovoltaic consumption evaluation function, the photovoltaic consumption level under different energy supply mode scenarios is evaluated and compared, and the effect of the light-storage and supply mode on the photovoltaic consumption rate is verified, and the economic benefits can be brought to the system through the“surplus electricity on the Internet”.
