Figure 6.2 shows the (partial) printout produced by the run of module 3 for CASENA.
Page 1 of Figure 6.2 is the cover page identifying the run and including the general input information about: the title, total number of years of analysis, printout output chosen and total number of sectors considered.
The printout continues with the results of the run for each period and year of study, along with some selected input data which are repeated in this portion for completeness of the output.
For example, Pages 2-5 of Figure 6.2 illustrate the portion of output corresponding to the first period (January, February and March) and first year of study (1980). First, and for each month of the period, the output reproduces the electric power demand in each hour and day of the month as shown in Pages 2-4 (this information is only printed under maximum output option). Then, the calculated values for the period as shown in Page 5 of the figure. The latter starts identifying the year, period and months included, followed by the period's maximum load, electricity demand, load factor and total number of hours. At the end of this summary, the output reproduces the point values of the L.D.C. and its integral for the total number of points requested (i.e., 52 points in our case).
Similar pages of output are printed for each of the remaining periods of the year, and after the last period has been considered, the printout continues with a summary table with the annual results.
Page 6 shows the summary table for 1980; this starts with the annual results on maximum load, electricity demand, load factor and total number of hours in the year, followed by a summary of the periods' results. At the end of this summary table, a message indicates the difference (0.9063 GW.h) between the total electricity demand given as input information and the one calculated from the L.D.C.
points, which in our case represents an error of about 0.017 % in the L.D.C. approximation.
The printout continues in a similar fashion for each year of study specified on the "LOADSCEN" file. Page 7-11 of Figure 6.2 show the last page of output (i.e., the annual summary table) for each remaining year for our sample run of CASENA, i.e. 1985, 1990,
1995, 2000, and 2015, respectively.

-6.5 Output Files:
As already explained in the introduction to this section, all results for each period and year of study are reproduced in the two output files created by the run; namely, "LOADWASP" and "LOADPLOT", as follows:
"LOADWASP" output file
The "LOADWASP" file may be used directly as input file to the WASP program; thus, the formats used for writing the necessary information onto this file correspond exactly to the input formats as required by WASP (see WASP-III User's Manual for details on these formats).
Figure 6.3 shows a partial listing of the "LOADWASP" file created by our sample run of module 3. As illustrated in page 1 of the figure, the information contained in this file starts with the title of the run, followed by the number of periods into which the year has been subdivided (4) and the number of coefficients to be used in the Fourier series representation of the load
duration curve in WASP (50).
The information for each year of study follows, beginning with the annual maximum load and year, followed by the maximum load in each period (relative to the annual maximum load), and finally, by the Load Duration Curve (L.D.C.) for each period.
Pages 1-2 of the figure show the information for the first year of study (1980). (Except for the fifrst period, only the first and last points of each L.D.C. have been included in the figure in order to reduce the total number of pages in this manual).
It should be noted here that the L.D.C. of the periods are expressed as fractions of load magnitude and respective duration for each L.D.C. point having a duration < 0.999995 (all L.D.C.
points with duration greater than this value are discarded by the program). This is illustrated in Page 1 of Figure 6.3 where the total number of L.D.C. points for the first period of 1980 has been reduced from 52 to 45 (compare with Page 6 of Figure 6.2).
Similar information follows for each remaining year of study including not only the reference years specified in the run of modules 1 and 2, but also for all intermediate years between two successive reference years as required by the WASP computer model.
Since only the information on hourly loads for the reference years is available to module 3 (read from the "LOADYEAR" file), it is necessary to make an additional hypothesis for intermediate years.
This consists in assuming that the L.D.C. per period that are calculated for each reference year are the same for all the years between the previous last and current reference year (this is equivalent to assuming that the period's and annual load factor will remain constant over these years). With this assumption, the maximum load for each intermediate year is simply calculated based on the average annual growth rate of the peak demand determined between the two successive reference years involved.
- 136
-For example in our run of CASENA, 1985 was the first reference year after 1980. Therefore, the "LOADWASP" file would include in
the information for 1981, the L.D.C. points per period calculated for 1985 and a peak (maximum) load determined on the basis of the average annual growth rate of the peak demand between 1980 and 1985.
The information for all other intermediate (1982, 1983, and 1984) would simply include the peak load of the year calculated on the
same basis of the average annual growth rate of peak demand already mentioned.
The above is illustrated in pages 3 - 4 of the figure which show the "LOADWASP" contents for 1981 through the beginning of 1985.
(again, only the first and last points of each L.D.C. are shown in the figure).
"LOADPLOT" output file
The "LOADPLOT" file contains similar information as to the one above discussed for the LOADWASP file, but presented in a different format.
At the IAEA, this file is used to produce plottings of the resulting L.D.C.'s on a computerized basis by means of a software package (TELL-A-GRAF) and a combined VARIAN (printer/plotter
device) as described in Section 3. Therefore, all formats used for writing information onto the LOADPLOT file follow the same lines as required by TELL-A-GRAF. The data in this file, together with appropriate instructions for controlling the page size, X/Y axis length and annotations, etc., can be given as input to TELL-A-GRAF for plotting the L.D.C.'s.
Figure 6.4 shows a partial listing of the "LOADPLOT" file for our run of module 3 for CASENA and Figure 6.5 gives an example of the type of plots that may be produced as described above.
It is worth mentioning here that if the computer installations available to the user lack of the necessary facilities for plotting
(therefore, no need for a LOADPLOT file), then it is not required to allocate this file at the beginning of a MAED-1 study and in the control cards for runs of module 3, file FT15 is declared as a DUMMY file. If other types of computerized graphics packages and plotting devices are available at the user's installations,
it may be required to modify some of the formats used by module 3 for writing information onto the ]LOADPLOT file.
