Abstract
In order to solve the problems of interconnection and communication security of monitoring system the distributed energy resources (DER) with different ownership, the virtual power plant (VPP) can be effectively employed. This paper proposes the information model of DER monitoring terminal based on the IEC 61850–7–420, and studies the extensible message and presence protocol (XMPP) mapping to realize the 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 also presents a platform to test the transmission performance of XMPP mapping, and the results show that XMPP properly meets the security communication requirements of DER monitoring system.
