netLoadRamp returns a data.table or a list of data.tables with the
following columns:
netLoadRampRamp of the net load of an area. If timeStep is not hourly, then these
columns contain the average value for the given time step.
Formula = netLoad - shift(netLoad, fill = 0)
balanceRampRamp of the balance of an area. If timeStep is not hourly, then
these columns contain the average value for the given time step.
formula = BALANCE - shift(BALANCE, fill = 0)
areaRampSum of the two previous columns. If timeStep is not hourly, then
these columns contain the average value for the given time step.
formula = netLoadRamp + balanceRamp
minNetLoadRampMinimum ramp of the net load of an area, if timeStep is not hourly.
minBalanceRampMinimum ramp of the balance of an area, if timeStep is not hourly.
minAreaRampMinimum ramp sum of the sum of balance and net load, if timeStep is not hourly.
maxNetLoadRampMaximum ramp of the net load of an area, if timeStep is not hourly.
maxBalanceRampMaximum ramp of the balance of an area, if timeStep is not hourly.
maxAreaRampMaximum ramp of the sum of balance and net load, if timeStep is not hourly.
For convenience the function invisibly returns the modified input.
