Electricity generation is largely dominated by conventional generators powered by fossil fuels. However, current trends are shifting towards installing renewable energy generation sources, such as wind and solar. Modern wind generators employ a converter in order to feed the generated power into the grid at the fundamental grid frequency. A converter is also required for solar generation for the same reason, converting DC to AC. In a 100% converter interfaced generation (CIG) based grid the existing operational rules regarding network security and system stability need to be re‐defined, whereby converter controls should be developed which replace the system services traditionally provided by synchronous machines. This paper highlights the challenges associated with operating a 100% CIG‐based system and the associated network locational issues required to maintain a stable system.
