Power electronics-microgrid interfacing

Power electronics is the key enabling technology for modern power systems. Power converters are increasingly used in a wide range of applications from generation to consumption levels. Due to the significant importance of power electronics in modern power systems, this book chapter presents the possible structure of the future power systems employing the microgrid (MG) technologies. Different MG topologies and converter structures are introduced. Moreover, the control and operation principles of power electronic converters in MGs are discussed. Two case studies are provided in order to show the importance of power electronics in operation and control of modern power systems. Finally, the chapter is summarized with highlighting challenges encountering modern power electronics-based power systems.
