InterOPERA Release Second Version of "Functional Requirements for HVDC Grid Systems"
InterOPERA has released the second version of the Functional requirements for HVDC grid systems and subsystems, offering a technology-agnostic description of the functional requirements for multi-terminal HVDC systems and subsystems.
Subsystem-level functions – which can be achieved by different technical solutions – are the most susceptible to cause adverse interactions. Therefore, these functions are formulated as verifiable requirements that each subsystem must meet at the DC points of connection, allowing different technical solutions to coexist.
The report details key functional requirements crucial for interoperability, including the DC-FRT requirement for AC/DC converters, the DC fault separation requirement for DC switching stations, and the dynamic and stability performance requirements for AC/DC converters. The applicability and validity of these functional requirements are evaluated using the InterOPERA demonstrator grid simulations to verify the effectiveness in mitigating interoperability issues.
