Research Paper: Overview of the Energy Storage Possibilities to Support the Electrical Power System

Electrical power grids/systems will basically change in the near future (or in some places, this
transformation has already begun): the increasing penetration of renewable energy sources causing
high percentage of intermittent and decentralized generation. This procedure will lead to problems
which are unknown for a conventionally planned and operated grid. Bidirectional power flows,
unbalances, power quality issues and voltage sags (dips) can occur. Energy Storage Systems are able
to play a key role in the solutions.
The scope of this research paper to provide an up-to-date and detailed summarization about:
 the technical background of the different technology possibilities, identify the main
parameters of a storage system (for classification and comparison);
 the electric power grid/system supporting applications;
 regulatory aspects of the deployment.
The information gathered from the accessible literature (listed in the reference with download links)
gave Regulators a chance to understand the main concepts of these solutions and keep the pace with
a rapidly growing part of the energy industry. If Regulators know when and how to utilize these
possibilities correctly (introducing support mechanisms), these problems with the power grid could
be avoided.
