GUEST EDITORIAL
The fifth feature, " Inertia Monitoring
on Renewable Energy Grids, " by
Antonio Enas, Chris Kimmett, and
Jack Joyce, discusses the importance
of grids in transition maintaining
adequate system strength and inertia.
The authors then describe a
method for accurate inertia measurement
in island grids by using a system
that was built and tested in the
Great Britain power grid. They posit
that with new real-time power system
inertia monitoring technology,
the transition to renewable energy
sources can be safe and realistic for
both large and small grid operators.
Next, " Supply-Side Flexibility for
Improved Hosting Capacity of Inverter-Based
Generation Technologies " is
by Michael Negnevitsky, Evgenii
Semshikov, James Hamilton, and
Xiaolin Wang. This article discusses
the common characteristics seen in
legacy isolated power systems and
the trends and challenges of system
transformation to a clean and sustainable
way of operation. While the
discussions and illustrations are
mostly centered around isolated
power systems located on islands,
similar trends can be observed in
other remote coastal and inland
locations (e.g., mines, military bases,
and remote communities, such as
those in Alaska and other rural settlements).
The article describes various
enabling technologies related to
conventional generation and evaluates
their potential for facilitating
the transition to the renewable
energy-based operation of island
power systems, without compromising
system stability. It includes a
figure summarizing many isolated
power systems around the world,
considering size and primary generation
technology.
The final article, " Renewable Energy
on the Apple Isle: Managing a High
Penetration of Inverter-Based Energy
Resources in Tasmania, " is by Andrew
Halley, Andrew Groom, and Mark
Davies. It provides an overview of the
Tasmanian power system, describes
the network's key attributes, and discusses
several solutions that have
been implemented to allow operation
with very high levels of IBR penetration.
The Tasmanian power system
has evolved over time from an
islanded power system dominated by
hydro generation to one that is interconnected
and has achieved over
90% instantaneous penetration of
IBRs. The article also describes the
real-time analysis and monitoring
capabilities of TasNetworks and evaluates
other future solutions for
enhanced system stability.
