1. Title of Tutorial
Modelling of Lithium-Ion Battery Energy Storage Systems for Grid Support Services
2. Abstract
In recent years, lithium-ion batteries have become the key energy storage technology for
the e-mobility industry, because of their outstanding technical characteristics which
include fast response, high power capability, and long lifetime. Consequently, due the fast
development, which was driven by the portable applications and e-mobility sectors,
lithium-ion batteries have started to be more and more considered for various grid support
services and for renewable’s grid integration. However, lithium-ion batteries are highly
nonlinear systems and their performances are degrading in time. Therefore, in order to
ensure technical and economic viability of a certain project, accurate knowledge about the
behaviour of the lithium-ion battery is demanded by the industrial user for both short term
operation (seconds to hours – performance modelling) and long term operation (days to
years – lifetime modelling).
The objective of this tutorial is to provide the audience with an extensive overview of the
lithium-ion battery energy storage technology, its operating principles, advantages and
drawbacks, grid integration issues and requirements. Moreover, a large part of the tutorial
is dedicated to the performance and lifetime modelling of the lithium-ion batteries.
Different modelling methods will be introduced and their characteristics (e.g., accuracy,
complexity etc.) will be assessed. Study cases illustrating the development and
parameterization of the performance and lifetime models, based on field and extensive
laboratory measurements will be presented and discussed as well.
