Selected critical simulation cases.

Contingency scenarios	Case	Case description
A; Starting of motor	A0	Single platform system: starting of a 9 MW motor at PF4, 1 or 2 GTs online with equal power sharing
	A1	Starting of 9 MW motor at PF4, 8 GTs online with equal power sharing at different platforms, no wind penetration
	A2	Starting of 9 MW motor at PF4, 8 GTs online with equal power sharing at different platforms, 100 MW wind penetration
B; Loss of gas turbine power	B1	Loss of a GT at PF4, no wind, and initially 9 GTs online at different platforms
	B2	Loss of a GT at PF4, 100 MW, wind and initially 9 GTs online at different platforms
C; Loss of wind power	C1	Loss of 25% (25 MW) wind power, 8 GT online with equal power sharing
	C2	Loss of 50% (50 MW) wind power, 8 GT online with equal power sharing
	C3	Loss of 100% (100 MW) wind power, 8 GT online with equal power sharing
D; Loss of interconnection between platforms PF1 and PF4	D1	Loss of interconnection—PF1 and PF4, 8 GTs online with equal power sharing at different platforms, with 50 MW wind
	D2	Loss of interconnection—PF1 and PF4, 8 GTs online with equal power sharing at different platforms, with 100 MW wind

*WT: wind turbine, GT: gas turbine, PF1–PF5: platforms 1 to 5.
