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.

The book consists of three parts: power quality control, neutral line provision and power flow control. In Part I (Power Quality Control), various control approaches to improve the power quality are covered. This includes the conventional PI control, proportional-resonant control and advanced  repetitive control. Several different strategies for  repetitive control, covering voltage control and current control, will be discussed. In Part II (Neutral Line Provision), one topology and several control strategies are discussed to provide a neutral line for inverters. For inverters used in distributed generation and renewable energy, this is an important issue as the loads are often unbalanced and there is a need for a path for the neutral current. A detailed analysis is provided. Conventional control strategy as well as the advanced  control strategy using voltage control and current control will be used. Part III (Power Flow Control) discusses, various issues including synchronisation, regulation of real and reactive power, parallel operation and the recently developed award-winning synchronverter technology. Synchronverters are inverters that mimic synchronous generators. Example design and experimental results are provided for most of the control strategies, which practictioners will find very useful.
