Research on distributed photovoltaic regulation method in transformer areas based on power line carrier communication

With the large number of low-voltage distributed new energy access, it has brought great challenges to the safe and stable operation of the power system, and it is necessary to effectively control the new energy with randomness, volatility and uncertainty in the distribution network. In this paper, based on the research of the site-wide distributed photovoltaic interactive system based on HPLC communication, the problems of data transmission network and communication mode are solved through the site-wide distributed photovoltaic interactive system networking, and the real-time data acquisition and precise command control of site-wide distributed photovoltaic power generation units are realized through the distributed photovoltaic interactive system. The system realizes the "observable, measurable, adjustable and controllable" requirements of the new power system after the high proportion of distributed photovoltaic is connected to the grid, helps the high proportion of distributed photovoltaic to the grid and reasonable consumption, and improves the security and stability of the power system.
