control and coordination approaches. Several field demonstrations
are summarized both in Europe and the United
States, where first-generation TE systems have been shown
to improve the balance between local consumption and
production and, by doing so, improve the integration of
renewable generation and mitigate congestion (i.e., local
power flow overloads) in distribution systems.
The third article, by Xiaosong Hu, Changfu Zou, Caiping
Zhang, and Yang Li, digs into battery energy storage that
can effectively stabilize the electric grid and aids renewable
integration by balancing supply and demand in realtime.
The importance of such storage is especially crucial in
densely populated urban areas, where traditional storage
techniques such as pumped hydroelectric energy storage
and compressed-air energy storage are often not feasible.
The authors summarize the principal roles that battery
energy storage play in the grid, and the categories of
commercial-scale batteries. The authors point out that rechargeable
batteries are today's most widespread electrical
energy storage devices and store electrical energy in the
form of chemical energy. The authors clarify the representative
commercial-scale battery technologies with different
technological characteristics and real-world applications
currently used in the electric power industry. Also, they
point out that battery management plays a critical role in the
integration of battery energy storage into the electric grid in
terms of performance, safety, reliability, and economy.
The fourth article, by Jairo Quiros-Tortos, Luis Ochoa,
and Timothy Butler, learns from one of the largest electric
vehicles (EV) trials in the world, My Electric Avenue (MEA)
in the United Kingdom. The MEA project deployed more
than 200 Nissan LEAFs to customers in the United Kingdom
to study the driving and charging habits of a geographically
and socioeconomically diverse population.
The authors provide details about the MEA trials, including
the main infrastructure adopted. Based on the data
analysis and network studies carried out, the authors present
key findings in terms of 1) the charging habits of EV
users, 2) the impact of EVs on low-voltage networks, and
3) the effectiveness of the proposed strategy to increase
hosting capacity. Using what was learned from this largescale
project, the authors then show the additional results
that aid in understanding the extent to which EVs could

Need Power Levels up to 250 kVA While
Testing Highly Capacitive Test Loads?
HVI Now Supplies Parallel
Resonant AC Test Sets
Our new PAR line of ac dielectric testers are designed to
meet the needs of those who do power frequency high
voltage ac testing and need power levels up to 250 kVA
while testing highly capacitive test loads. Employing ac
resonant technology, outputs of 50 kV at 5A (for example)
are possible with an input of only 230 v, 90 A. That is an
output of 250 kVA with an input of only 20 kVA.
PAR models are available with output voltages up to 100
kV (at 1 Amp) and with output current ratings up to 8 Amps at 0 to 32 kV. Typical applications of these products would be
to test power factor capacitors, bushings, instrument transformers, rotating machinery, transformers, power cables, shunt
reactors, and other electrical apparatus.
The PAR models are a two-piece design consisting of a PLC control
section and a high voltage section. (Model PAR-50250FC5)
