Abstract
focus of this public deliverable is twofold: On the one hand, it provides clarification on selected
requirements from the network code (NC) RfG as well as NC HVDC and gives guidance in terms of
compliance testing against the aforementioned network codes (see chapters 2 and 3) while, on the
other hand, it demonstrates the found specific mitigation measures against power system stability
issues caused by increasing levels of PE penetration using a sufficiently complex test system (see
chapter 4) and concisely summarizes to the public the general key findings of WP1 (see chapter 5).
When the very successful European network codes NC RfG, NC HVDC, and NC DCC were published,
it turned out that some requirements therein were subject to interpretation by the reader.
MIGRATE WP1 conducted a survey among all ENTSO-E TSOs and asked the adopters of these NCs
for unclear requirements that need clarification. Their answers include their unsureness of e.g. how
to interpret “synthetic inertia” and “fast fault current”: What exactly is inertial response, and how
can it be parameterized? How to understand the “fast” in “fast fault current”? Which current (active
or reactive?) is meant, and what shall happen with the other current type during “fast fault current”
contribution? Scientific clarification on these and additional requirements is provided in chapter 2.
Before this background, how to perform a reliable and legally admissable compliance test against
the requirements set in the NCs is another challenge that the European TSOs will be frequently
confronted with in the future. While it is out of scope and resources of the MIGRATE project to
provide an elaborated compliance testing methodology, chapter 3 gives an overview of how
selected EU TSOs have addressed this problem.
The overall goal of MIGRATE WP1 was to identify and quantify power system stability issues that
may arise with increasing levels of PE penetration as well as to provide mitigations measures
against them. The application of these mitigations measures is demonstrated in chapter 4 using a
sufficiently complex power system, i.e. the so-called Irish Test System. It shows to the interested
reader how the proposed mitigation measures can help increasing the PE penetration level in a
realisitic power system and how some mitigations measures interlock in order to ensure global
power system stability.
Using the found mitigation measures, MIGRATE WP1 is confident that it is possible to increase the
PE penetration level in a given power system up to 60 to 70 % in the first stage (fine tuning of
outer control loops of existing PE units) and even further towards 100 % in the second stage
(introduction of grid forming control in some PE units). It is worth mentioning that this
development path (in particular the grid forming control strategy proposed) is compatible with the
finding of MIGRATE WP3 that focused on the operation of a 100-% PE power system.
The general key findings of MIGRATE WP1 are presented in chapter 5 along with references to
corresponding scientific papers that were published by the MIGRATE WP1 researchers for further
reading. It is very difficult to concisely summarize the extensive research work done during the
lifetime of a four-year project. The interested reader is therefore guided to the scientific papers
developed within the MIGRATE framework and invited to contact the MIGRATE WP1 members
anytime he would like to discuss the scientific results with them.
