A two-area system is inter-connected by a tie-line, and has the following parameters on the specified power bases. Assume the system to be lossless. Area Speed Regulation (R) Frequency Sensitivity Load Coefficient (D) Power Base 1 0.06 0.3 1000 MVA 2 0.08 0.9 500 MVA The system is initially at 60 Hz, when a load decrease of 100 MW occurs in Area 2. Determine: (a) The new steady-state frequency. (b) The change in the transacted tie-line flow between the two areas (AP12) in steady-state. (c) The change in the generated power in each area.
