A method for multipoint secure access of IED to distributed new energy information system

In recent years, the proportion of distributed energy integrated into the power system has been continuously increasing. However, due to the inherent characteristics of distributed energy, its IEDs pose significant security risks when connected. So, when accessing IEDs, a complex authentication process is required, which is not conducive to the flexible access of IEDs. Therefore, this article proposes a method for IED multi-point secure access to distributed new energy information systems, including offline authentication and online access. This method can achieve efficient and secure access of IEDs.
