TMAC Generation Signalling Device

The Generation Signalling Device (GSD) provides a means of controlling the generation capability of AS4777 compliant solar inverters during emergency situations by asserting DRM0 on the inverter DRED port when the level of renewable generation becomes a threat to grid stability. This provides electricity network operators the ability to implement emergency protocols to ensure continuity of supply when the only alternative would otherwise be widespread power outages for customers.
