! 300-sec solar ramp screen
New Loadshape.SolarRamp npts=300 Interval=(1 3600 /) mult=(file=solarramp.csv)

! define the generator
New Generator.2MWGen   Bus1=450 kV=4.16  kW=2000  PF=1  Duty=SolarRamp 

! Solve and let regulators settle out with generator on line
Solve

! Put Monitor in Line L99 to capture voltages and currents
New Monitor.Mon1 Element=Line.L99 Terminal=1

! Run 300-point dutycycle
Solve mode=dutycycle number=300 stepsize=1s

! Plot Monitor Results
