Comparison of system dynamic responses during higher violation of contracted demand and different time delays in the system. a Frequency deviation in area 1 for 4% and 6% violations in contracted demand from nominal one. b Power generation in area 1 for 6% violations in contracted demand from nominal one. c Tie-power deviation in line connecting Area 1 and 3 for open communication channels of 50, 100 and 300 ms. d Frequency deviation in area 4 for open communication channel delays of 50, 100 and 300 ms
