Growth defines a load scaling factor and a growth percentage for each year. These numbers can be specified for a scenario of maximum 30 consecutive years.
Scaling
The scaling factor is always applied.
Growth
When performing a load flow calculation, it is possible to indicate which period the growth should be determined. This growth can be calculated linearly or exponentially. A "negative growth" is also possible.
A growth is defined in % per year. This allows the load to be calculated over a number of years. In Vision the growth and scaling can be set per year. The formulas below show the calculation of the power P(n) in year n, with a percentile growth g(i) in each year i and scaling factor f(n) in year n :
linear:
exponential:
In the Options at Network | Default trends | Growth one or multiple growths can be specified, which will subsequently be added to each new network.
There are seven predefined growths
