LEGO is a complex yet easy to handle multitool, applicable for academic research, commissioned research projects, as well as teaching. LEGO’s modeling philosophies are: modularity and flexibility. Its underlying temporal framework enables addressing a plethora of technical, economic, and policy studies. Depending on a studies’ scope one can compose their individual modeling environment of interest, by simply deciding which thematic LEGO blocks to use and which to omit.
LEGO’s objective function minimizes total system costs (investment and operational) for a static horizon e.g., one year. LEGO runs on either chronological hourly data, or representative periods. This, for example, provides computational advantages of representative period frameworks when modeling short- and long-term storage technologies simultaneously. LEGO currently includes following model option blocks:
Alongside model options, one can specify their individual generation and/or transmission investment portfolio. Thus, one can decide if LEGO considers a
Last but not least, LEGO also includes various policy options:
