In recent years, distributed new energy represented by photovoltaic technology has been increasingly widely used, and the scale of grid connection is increasing. In response to the increasingly urgent demand for distributed photovoltaic interactive communication, this article analyzes the model of distributed photovoltaic interactive data flow, builds a distributed photovoltaic user interactive communication model based on OPNET software, and builds a small simulation network that includes photovoltaic users and aggregators, verifying the practicality of the model.
