Control of Power Inverters in Renewable Energy and Smart Grid Integration

Integrating renewable energy and other distributed energy
sources into smart grids, often via power inverters, is arguably
the largest "new frontier" for smart grid advancements.
Inverters should be controlled properly so that their integration
does not jeopardize the stability and performance of power systems
and a solid technical backbone is formed to facilitate other
functions and services of smart grids.

This unique reference offers systematic treatment of important
control problems in power inverters, and different general
converter theories. Starting at a basic level, it presents
conventional power conversion methodologies and then
'non-conventional' methods, with a highly accessible
summary of the latest developments in power inverters as well as
insight into the grid connection of renewable power.

Consisting of four parts - Power Quality Control, Neutral
Line Provision, Power Flow Control, and Synchronisation -
this book fully demonstrates the integration of control and power
electronics.

Key features include:

• the fundamentals of power processing and hardware design

• innovative control strategies to systematically treat the
  control of power inverters

• extensive experimental results for most of the control
  strategies presented

• the pioneering work on "synchronverters" which has
  gained IET Highly Commended Innovation Award

Engineers working on inverter design and those at power system
utilities can learn how advanced control strategies could improve
system performance and work in practice. The book is a useful
reference for researchers who are interested in the area of control
engineering, power electronics, renewable energy and distributed
generation, smart grids, flexible AC transmission systems, and
power systems for more-electric aircraft and all-electric ships.
This is also a handy text for graduate students and university
professors in the areas of electrical power engineering, advanced
control engineering, power electronics, renewable energy and smart
grid integration.
