Grid Code Compliance Monitoring PFM300-GCC
An increasing number of independent power producers (IPPs), such as wind, pv or conventional power plants, are connecting to public transmission and distribution grids. Grid connection contracts with grid operators include obligations to comply with performance requirements set out in the relevant grid codes. These grid codes will typically specify the expected behaviour of the plant during network disturbances, requirements for support of the steady-state and dynamic stability of the grid, and obligations relating to ancillary services provision and power quality. Non-compliance with these grid code requirements can result in payment reductions or even disconnection from the grid as well as conflicts between the parties involved.
The new Grid Code Compliance Monitoring System PFM300-GCC has been designed to carry out online audits of the compliance of your power plant with the grid code, automatically report on any grid code relevant issues and provide transparency between parties through traceability of non-compliance events. In this innovative solution DIgSILENT has successfully combined its considerable expertise in both hardware systems for monitoring and power system simulation software development, to provide an online assessment of grid code compliance.

Key Benefits
Features
Advanced Application Case
As well as providing the VT and CT signals from the point of connection, the PFM300-GCC offers monitoring of the plant status. In the case shown below, plant signals relating to the frequency response of the Battery Energy Storage Systems (BESS) and the pv generator are also evaluated. For other systems, turbine or governor signals can be recorded and included in the Grid Code Compliance Monitoring analysis, to check for compliance with the ramp rate control and frequency response settings. Similarly, voltage set points, dynamically changed by the network operator, can be monitored together with AVR signals.
Hardware Variants
Base Configuration
- For point of interconnection: 3xVT, 3xCT channels, breaker status and 3 channel set point measurement (Total 9 analogue and 8 digital channels). Incl. NTP/PTP time synchronization.
Custom Configuration
- Additional VT, CT and PPC signal inputs for advanced grid code requirements considering BESS systems or equivalent controllers.
