DANSK DSF/IEC TS 62786-1 ED1 PDF

This Technical specification provides principles and general technical requirements for distributed energy resources (DER) connected to an electric power network (in the following: the “network”). It applies to the planning, design, operation and connection of DER to networks. It includes general requirements, connection scheme, choice of switchgear, normal operating range, immunity to disturbances, active power response to frequency deviations, reactive power response to voltage changes, EMC and power quality, interface protection, connection and start to generate electrical power, active power management, monitoring, control and communication, and conformance tests. It is supplemented by additional parts of IEC 62786 series, covering specific aspects. This document specifies interface and interoperability requirements for connection of DER to a network operating at a nominal frequency of 50 Hz or 60 Hz. These requirements are intended for application at the point of connection (POC) of the DER to the grid. In some situations, the requirements may be the applied at the AC terminals of the generator. Additional parts of IEC 62786 provide more specific requirements.
