@@ -43,7 +43,7 @@ A scenario is defined by the following objects:
   - Substations that change voltage levels (from high to low, or the reverse)
   - Transmission lines that carry power from one place to the other (between two substations, between a substation and load bus, between a generator bus and a substation, etc.) - Both, high voltage AC and DC lines are used in our model
   - Generator cost curve that specifies the cost as a function of power generated ($/MWh) - These are determined by fuel cost and generator efficiency

   - Profile for the renewable generators consists of hourly power output
   - Load profile gives the hourly demand (MW) in various load zones, which are geographic entities such as a state or a portion of a state
