Grid operators, manufactures, researchers, and policy makers must
continually discuss conditions under which GFM technology is
needed and performance requirements should be clearly defined.
characteristics, a dynamics time scale of 3-10 times faster than
present systems could be achieved in a secure way.
Summary
Several interconnected systems already have reached or are
expected to reach very high penetration levels of IBPSs in
the near future, which leads to operating challenges mainly
associated with reduced system strength, synchronous inertia,
and black start capability. Some SOs in these areas have
determined the required levels of system strength and synchronous
inertia below which action is needed.
In recent years, GFM technology has been intensively
discussed as a possible solution to these issues. Researchers
are developing alternative GFM control strategies and
studies show that only a portion of IBPSs need to be GFM
to ensure secure system operation. The studies also demonstrate
the compatibility of various GFM control strategies
used within one power system.
Several actual projects, mainly in small isolated systems,
successfully demonstrate the feasibility of GFM technology.
However, the lack of clear functional requirements and low
number of use cases do not provide a sufficient incentive for
manufacturers to develop commercial GFM IBPSs for bulk
power system applications. Market signals are desirable, where
possible. No one-size-fits-all solution is suitable; combinations
of GFM, GFL, and synchronous machines need to be considered
with a detailed cost-benefit analysis in each case.
Grid operators, manufactures, researchers, and policy makers
must continually discuss conditions under which GFM technology
is needed and performance requirements should be clearly
defined in grid codes or standards. Manufacturers then can
develop equipment with new capabilities that balance performance
and costs. This dialogue is crucial to maintain secure and
efficient system operation with a high penetration of IBPSs.
