Aim of Energy System Modeling
Today there is almost an infinite number of possibilities to design a system for heat an electricity supply. It is common practice to select some of these possibilities, compare them and select the most cost effective one.
But, is this the most efficient solution overall? Using energy system modeling, there are no distinct variants anymore. There is a single model that contains all possible technologies in form of a lower and an upper boundary. A computer varies the installed capacities of all technologies within these boundaries, until a target variable is minimized for the whole system.
Possible target variables are:
- Cost (minimal cost, lower right point in the chart)
- Emissions (minimal emissions, upper left point in the chart)
- Cost, with a maximum emission goal given (points on the Pareto curve i the chart)
Results are only useful, if they are presented in a human readable format. Energy system models deliver specific technology combinations, installed capacities of single units, load curves, monetary costs and spatial distributions of installed units in open geodata formats.
