Foreword
The global energy situation in 2022 is under critical pressure and future predictions are saying that a large shift of energy mix is neededbetter today than tomorrow. A main reason is the challenging predictions of a future climate crisis, which includes a global average temperature increase of more than 2, or even higher due to the carbon emission from fossil fuelsif nothing is done on the planet. A major need is to change the fossil fuelbased electricity production to become based on renewables (especially wind and solar), which directly gives a significant reduction in carbon emission, but there is also a need to transform the transportation sector to become electrifiedwhich also will give a very direct and clear reduction of the emission. The transportation sector is fully based on fossil fuel todaybut electrifying ita large carbon emission reduction can be achieved. A third area is to save energy either by using less energy in our daily living or make the conversion processes much more efficient. One example seen in the past has been the classical bulbs, which today all are based on LEDs with an amazing energy reduction. The world will in the future need to be based on electricity instead of fossil fuel and my prediction is that electricity will cover above 60 % of all the global energy consumption achieved within the next 40 years to come.
To realize such energy system, we need to convert electrical power from one stage to anothere.g., from ac to dc or vice versa. This is done by the modern power electronics technology, which has been present for more than 60 years. In the last decades, the most dominant power converter topologies have been the voltage source converterbased systems and they are on a very rapid expansion in many different applications (i.e., wind, solar, storage, EV-chargers, EVs, adjustable speed drives, HVDC power transmission). The voltage-sourced systems can achieve very fast dynamics thanks to the used capacitors and fast switching power devices, high power density, low cost, and they are very scalable in power. Further ondue to the high dynamic ability in the systemthe systems where they are applied into will also become fastand here often large energy savings can be achieved or a high performance. We are seeing millions of such units around in the world and that will soon be billions in the global power system.
This book with the title Grid Connected ConvertersModeling, Stability, and Control by Profs. Hassan Bevrani, Toshiji Kato, Toshifumi Ise, and Kaoru Inoue is addressing this important technology in order to give researchers and industry a unique understanding and propose methods to improve the performance of grid connected converters. This book comprises 9 chapters with Part I discussing Concepts, fundamentals, modeling, and dynamics analysis and a Part II having the title Control synthesis for stabilizing and performance enhancement. This book gives the fundamentals about the grid-connected converters and comes up with many interesting methods on how to analyze the converters connected to the grid. It also improves the performance on them if certain problems are expected to appear.
I enjoyed reading this book where the topics are presented in a new, easy, and understandable wayI hope you enjoy the work too.

Preface
Increased needs for electrical energy and environmental concerns besides growing attempts to reduce dependency of power generation to fossil fuel resources have caused power grid industries to set an ambitious target of renewable generation. Therefore, the capacity of installed converter-based distributed generators (DGs) and renewable energy sources (RESs) over the world is rapidly growing; and this increases the significance of
