1. You are given two areas connected by a tie-line with the following characteristics Area 1 R=0.005 pu D=0.6 pu Area 2 R = 0.01 pu D=1.0 pu Base MVA =500 Base MVA = 500 A load change of 150 MW occurs in Area 2. What is the new steady-state frequency and what is the change in tie-line flow? Assume both areas were at nominal frequency (60 Hz) to begin 620 Dal
