Research of smart grid cyber architecture and standards deployment with high adaptability for Security Monitoring

Security Monitoring is a critical function for smart grid. As a consequence of strongly relying on communication, cyber security must be guaranteed by the specific system. Otherwise, the Demand Response (DR) signals and bidding information can be easily forged or intercepted. Customers' privacy and safety may suffer huge losses. Although OpenADR specifications provide continuous, secure and reliable two-way communications in application level defined in ISO model, which is also an open architecture model for adopted security systems, no specific or proprietary technologies is restricted to OpenADR itself. It is significant to develop a security monitoring system. This paper discussed the cyber architecture of smart grid with high adaptability for security monitoring. An adaptable structure with Demilitarized Zone (DMZ) is studied. Focusing on this network structure, the rational utilization of standards is investigated to provide a smart grid communication network with better performance and higher security, whilst it avoids the extra investment of an individual security monitoring network as far as possible.
