Data security management method and system for low-voltage distributed photovoltaic

The invention relates to a low-voltage distributed photovoltaic data security management method and system, and belongs to the technical field of intelligent power distribution and utilization. An encryption service subsystem authorizes a system root key to a transformer area data acquisition terminal, and the transformer area data acquisition terminal encrypts and decrypts a regulation and control instruction through the encryption service subsystem and issues the regulation and control instruction to a photovoltaic management terminal; the photovoltaic management terminal is accessed to the electricity utilization information acquisition service cloud platform through the transformer area data acquisition terminal, and the transformer area data acquisition terminal carries out encryption and decryption processing on access data of the photovoltaic management terminal through the encryption service subsystem. According to the invention, the response efficiency of low-voltage distributed photovoltaic regulati
