investment analysis
1. Set Timesteps ...
1-3 days (24-72 timesteps) per
segment are recommended for
operational analysis
2. Set Segments ...
The load and price profiles
given for each component is
multiplied with the Coefficient
for the respective Segment
Any number of Segments
(seasons) may be specified
by clicking New.
The sum of Weight over all
Segments must equal one
year (365 when Timestep is
set as 24 hours)
3. Set Years ...
The Years parameter defines
the Investment periods in the
case. They do NOT have to be
of equal length.
The load and price profiles
given for each component is
multiplied with the Coefficient
for each Year
