CC CC, denoting equivalent load curve card
DATE Period corresponding to equivalent load curve (YY-MM-DD)
PL Load forecasting value in corresponding period (MW)
HY Sum of hydro power outputs in corresponding period (MW),
optional
SG Sum of other small power plant outputs in corresponding
period (MW), optional
PA Power imports from the external system in corresponding
period (MW, PA¼0, no power exchange; PA>0, import
power; PA<0, export power)
SZ Sum (MW) of capacities of units in the system not reaching
their full capacity in the corresponding period or minimum
reserve capacity (MW) of the system
Notes: (1) To minimize the repeated input of data, in case of no changes in the equivalent load
curve data in adjacent periods, only fill in the period when the data appear for the first time, and
never fill in the curve data in new periods until the curve data have changes. That is, only fill in the
data of curve inflection points in the equivalent load curve card, without any evenly spaces filled
out. (2) The period filled in the equivalent load curve card shall cover the entire GMS time range,
otherwise the GMS cannot proceed.

(7) GMS data file end card (END). The last line of the data file shall be filled as END, as
shown in Table 3.9.

END End, denoting the end line of input data (required)

(8) Comment card (**), which allows users to add some comments not involved in calculation
when inputting the data, to make the input data more readable, and keep data revision more
convenient. The format of the comment card is shown in Table 3.10.

** * *, denotes the message comment line
Any string of characters
Note: The comment line may inserted anywhere in the data files, without limit of lines.
