Change to FCAS Regulation constraint equations for managing time error

AEMO is changing the way the FCAS constraint equations work for automatically increasing the regulation when the time error exceeds 1.5s in the Mainland. Currently the regulation is required from all NEM regions when there is a Mainland (NSW, Qld, SA and Victoria) time error.

The change to be made is to set the FCAS regulation requirements for Mainland regions only when there is a Mainland time error exceedance.

The FCAS requirements from all NEM regions of 120 MW lower regulation and 130 MW raise regulation has not changed.

The calculation for the regulation is detailed in SO_OP3715, section 19.

This change will take effect at 1700 hrs on 25 October 2016.
