Comprehensive resource discussing specific challenges and control solutions associated with operating inverter-based resources in weak grid scenarios

Weak Grid Integration of Inverter-Based Resources delves into current operational challenges and control solutions associated with inverter-based resources (IBR) in weak grid scenarios, with real-world examples included throughout to elucidate key concepts. The book introduces the control architecture of IBR power plants and the underlying AC circuit topology, providing readers with a comprehensive overview of the system.

It discusses specific operational challenges and examines how they relate to the grid-following control system and circuit characteristics. The book also reviews various grid-forming control designs and their role in enhancing weak-grid operation, while analyzing potential challenges arising from interactions between IBRs and series or shunt compensation. In addition, it investigates the different fault behaviours associated with grid-following and grid-forming control.

Written by two highly qualified experts, Weak Grid Integration of Inverter-Based Resources includes information on:

• IBR inverter-level and power plant-level control logic
• Root causes of a variety of oscillation phenomena
• Impact of series and shunt compensation on grid characteristics
• Stability analysis and associated modelling techniques, including complex vector-based modelling and analysis and forming customised feedback systems
• Fault behaviours and their connection to IBR control logic

Comprehensive in scope, Weak Grid Integration of Inverter-Based Resources appeals to a wide spectrum of readers in the field, including professionals in the power industry and university students in related programs of study.
