Generators: There are four generators supplying a load as shown in Fig.1.For generators G1,G2,G3 and G4 each either has full capacity of 60 MW or 0 MW when failed.The failure rate of each generator is 0.1/day and mean-repair-time is 24 hours.
Transmission Lines: The transmission lines are exposed to two states of weather. The failure rate of each transmission line is assumed to be 10/year during the normal weather and 100/year during the adverse weather The mean down time is 8 hours.Capacity of each line is 100MW
Weather: The weather fluctuates between normal and adverse state,mean duration of normal state is 200 hours and mean duration of adverse state is 20 hours
Load: Load fluctuates between different states.the dailv load cvcle is Load (MW) 0-4 40 4-8 101 8-12 201 12-16 I01 16-24 40
