Weidong Xiao is an Associate Professor within the University of Sydney's School of Electrical and Information Engineering. His research interests include PV power systems, power electronics, dynamic systems and control, and industry applications.

?This book is an excellent explanation of PV power systems and its controls. It brings sufficient knowledge on modeling and designing different kinds of PV systems (both standalone and grid-tied). In the first 4 chapters, it focuses more on the introduction and PV basics such as PV classification, characteristics, and mathematical models. This information will lead readers to a general understanding of PV fundamentals, providing a smooth transition from basic knowledge to advanced industrial PV applications. It perfectly combines the theory and practical exercises. In chapter 5, it discusses the design, simulates and evaluates of state-of-art system components such as PV-side converters, battery-side converters, and grid-side converters. After discussing the system components, in the next two chapters, the complete dynamic modeling of PV systems are introduced. This book emphasizes the computer-aided analysis and simulation verification. The detailed equations behind the functions are provided, and the simulation blocks used are built using the commonly used blocks in Simulink. Readers can easily follow the step-by-step instructions to simulate the whole PV system in Matlab. Apart from system modeling, the control of the entire PV system like linear control and MPPT technology are also addressed. This book fulfills important demand in both academia and industry. It is also a perfect choice to support teaching senior-undergraduate and graduate courses.? ? Dr. Yang Du, Xi?an Jiaotong ? Liverpool University ?This is a textbook for a course that would appear to be suitable for upper level graduate students. It could also be used by undergraduates and master?s degree level students who want to get a general idea of how solar electric power systems work. The book reads well and should be accessible to most college students and certainly almost all graduate students. In addition to its use for higher education, this book could be used by engineers and utility executives
