Philipp Kassing:

{{GlossaryTermTemp
|Definition=Mathematical function of system variables (e.g. costs, CO2-emission,) whose value is to be optimized. While optimizing, the solver searches system variables that lead to an optimal the objective function value (maximum or minimum).

Philipp Kassing:

{{GlossaryTermTemp
|Definition=In an optimization, constraints are conditions which must be met while finding the optimum. Examples: „Meet the heat demand” or “Due to noise pollution the CHP must not run during night time”.
Also common: Constraints that limit the permitted range of system variable.

Derived Result

{{GlossaryTermTemp
|Abbreviation=KPI
|Ambiguities=Key Performance Indicator
|Definition=Quantity which is calculated during post-processing by appropriate formulae (e.g. efficiency, mean value, full load hour, electricity generation costs, cumulative amount of energy). Key performance indicators (KPI) should be suitable to quantify differences between the scenarios. The definition of a KPI depends on the research topic. Usually it is necessary to define various KPIs.

= FAQ =

=== What is a glossary? ===

A glossary, also known as a vocabulary, or clavis, is an alphabetical list of terms in a particular domain of knowledge with the definitions for those terms. [wikipedia]

=== What is the main purpose? ===

We often face misunderstandings in discussions about energy system modeling while talking about it from different points of view or different disciplines.This glossary has the aim to develop a common understanding of terms in the field of energy system modelling.

 

 

=== How to handle multiple definitions for one term? ===

Every term can have several '''definition'''s. They are serially numbered. In this way the different understandings of a term become obvious and can be better understood and handled in future. The usage of terms can be discussed openly without dictating a certain definition.

Suggestion openMod 2017: add a disambiguation section in case different wording for the same term is displayed.

Grouping of words can lead to further disambiguation. When a user clicks on a particular term, they would be provided with a list of other asscociated ones (i.e solar power, PV panels).

It's not necessarily that there is universal consensus over one particular term.However, the description displayed at the top is that one that the majority agrees on.

 

=== What are the abbreviation used for? ===

'''Abbreviation'''s are often used in code. Models often define their own abbreviations, which can differ from the ones used in other models. Therefore, different abbreviations may be displayed (example: abbreviations for the term "abbreviation": abb. [Model X], abbr. [Model Y]).

 

=== How to handle different terms for the same thing? ===

Every term that is used by the community can be added to the glossary. Similar terms can be linked in the category '''Synonyms.'''
