Microgrid Dynamics
and Control
By Hassan Bevrani, Bruno Francois,
and Toshifumi Ise
Utilities around the world are gradually
moving toward distributed renewable
energy sources to reduce their carbon
footprints and meet energy demands.
Microgrids offer an efficient way to
integrate renewable variable energy
sources into the grid and address local
reliability concerns.
The increased use of distributed variable energy resources and a changing
electric market can stress transmission
systems. It is becoming necessary to
account for system changes that result
from the following factors:
✔ growth in utilizing variable energy
resources, such as wind and solar
✔ flow pattern changes and bidirectional flows on certain paths
✔ system maintenance work compressed into a few months, which
minimizes adverse market impacts while continuing to avoid

power outages during critical operational periods
✔ restrictions due to deratings and the
replacement of aging infrastructure
✔ steadily increasing energy transfers as power is bought and sold to
meet load, especially during periods of fuel scarcity or major price
differences between systems
✔ f luctuating demand that requires an increased response
and additional distributed energy resources
✔ retiring old generation facilities that are located close to
load centers.
Microgrids are the building blocks of
smart grids. They can provide solutions to some major system problems

and defer the need for large-scale system and distribution-system capital
improvements. The load, generation,
and storage components are very close
to each other in a microgrid, which
further reduces operating expenses by
decreasing the use of, and associated
losses from, the transmission system.
A properly designed microgrid also
greatly improves reliability. However,
engineers must first have the ability
to study microgrids and integrate them
with the overall system.
Microgrid Dynamics and Control
is required reading for anyone interested in comprehensively learning about
all aspects of microgrid modeling, operation, and control. This book covers
the modeling of different equipment
used in the microgrid and the controls
required to operate the system reliably. It begins with a discussion of the
modeling of renewable energy sources, including solar, wind, hydro, biofuel, and geothermal, and then shifts
to cover the fundamentals of primary
and secondary control mechanisms.
The interconnected and isolated operating modes of a microgrid are also
fully addressed.
Modeling concepts that are required
for interconnecting the main grid with
the microgrid are discussed as well as
simulation results. Stability equations
used to assess dynamic performance
and an efficient approach to hierarchical control are presented.
DC micogrids have recently become a major area of interest to electric
