Design of information interaction interface between electrical home appliances and smart grid

This paper researches and designs an information interaction interface, which exchanges information between electrical home appliances and smart grid, thus accomplishes the function of data acquisition and appliance control. With regard to the designed logical functional structure of external and internal grid information interaction interface, procedure of information interaction, interaction scheme and communication protocol during interaction process is analysed in detail. The procedure of interactional service between electrical home appliances and smart grid is illustrated by describing coordinating operation of grid information interaction interface´s functional modules, by which the goal of power demand response, energy management and power load control is achieved finally.
