Question

3. A two area power system is connected by a tie line with the following characteristics. Area 1: Droop R = 0.01 PU, D = 0.8 PU, Base MVA = 500 Area 2: Droop R = 0.02 PU, D = 1.0 PU, Base MVA = 500 A load change of 100MW (0.2 pu) occurs in area 1. (a) What is the steady-state frequency in Hz and what is the change in tie line power flow in MW? Assume both areas were at nominal frequency of 60 Hz. (b) What is the area control error (ACE) of each area? The two areas frequency bias constant are B1= 0.05 and B2= 0.06.
