Communication Application of Distributed Energy Resources Monitoring System Based on XMPP

In order to solve the problem of interconnection and communication security of distributed energy resources (DER) monitoring system with different ownership, the virtual power plant (VPP) can effectively monitor and control DERs. this paper constructs the information model of DER monitoring terminal based on IEC 61850-7-420, and studies the XMPP mapping to realize the information model and real-time data communication service. The built-in security mechanisms TLS (Transport Layer Security) and SASL (simple authentication and security layer) of XMPP can ensure the security of information transmission. This paper builds a test platform to test the transmission performance of XMPP mapping, and the results show that XMPP can meet the security communication requirements of DER monitoring system.
