describes some of the research efforts
and results from a five-year project
focused on developing
new guidelines, best
practices, and rules of
thumb for the integration of utility-scale PV
systems into the distribution system. the
project has included
extensive distribution
circuit modeling, PV
impact assessment, PV
impact quantification,
and PV impact mitigation-through the
use of advanced PV
inverter functionality-
of three circuits within
southern California
edison's service territory that had large
amounts of utility-scale PV interconnected to them.

the last feature article, "heat and
Dust," examines possible solar deployment scenarios for the
country of Chile, which
has an extremely high
solar potential. Chile
faces a variety of technical challenges with
the proposed largescale deployment of
PVs including developing solutions to
match the need for constant power supplies to
mining operations. the
article discusses several
combinations of PVs
with energy storage
and other technologies
including the use of
controllable loads (such as mining pumping systems, desalination plants, and
pump storages) to solve the variability

The large-scale
deployment
of distributed
energy resources
presents
many unique
challenges in
terms of grid
integration.

issues associated with PV-based Ders.
Additionally, integration concerns are
being addressed by using PV plants that
have dynamic voltage and power management, frequency droop control, and
fault-ride-through capacity to maintain
grid stability.
Finally, iain Macgill and Anna
Bruce, in their "in My View" contribution, provide a thought-provoking
synopsis of the state of distributed PV
deployment in Australia and discuss
both technical grid integration issues
as well as business-related issues that
Australian distribution network service
providers are currently facing. with Australia's high level of PV system deployment, particularly in certain states, the
challenges they are currently addressing
may inform both technical and business
solutions for others with similar system
and regulatory structures.

Don't put your customers in the dark unnecessarily.

Protect your customers from more of the preventable
outages with CAPE 14 protection analysis software
Electrocon's CAPE (Computer-Aided Protection Engineering) software allows utilities
to determine if their networks are compliant with NERC PRC-019, PRC-023, PRC-026
and other industry standards. The CAPE TS-Link™ option gives electric power
engineers a unique tool to evaluate the fast, wide-area control needed to avoid
cascading outages and blackouts. Realistic device models make CAPE the most
powerful protection simulation software available.
