The Challenges that Distributed Energy Resources Present to Protection and Control Systems
Distributed Energy Resources (DER) are becoming a major part of the drive towards a cleaner environment within the context of the Smart Grid.They are of different sizes and types and are being connected at all different levels of the electric power system-transmission, distribution and low voltage.This introduces significant challenges for their integration in protection,automation and control systems at the transmission and distribution level of the system which need to be considered in the engineering and testing of the protection devices and systems.The paper describes the requirements for protection of systems with DERs.Then in looks into the IEC 61850 standard and analyses the principles of object modeling in it, focusing on the modeling of the functional hierarchy and the System Configuration Language and its use.An example of the model of a distributed generator and its integration in an IEC 61850 based system is presented.Existing logical nodes and their use are first considered.New logical nodes specific to the distributed generation domain are then described.The need for development of extensions to the IEC 61850 System Configuration Language is discussed at the end of the paper.
