Electric power transmission relies on AC and DC grids. The extensive integration of conventional and nonconventional energy sources and power converters into power grids has resulted in a demand for high voltage (HV), extra-high voltage (EHV), and ultra-high voltage (UHV) AC/DC transmission grids in modern power systems. To ensure the security, adequacy, and reliable operation of power systems, the practical aspects of interconnecting HV, EHV, and UHV AC/DC grids into the electric power systems, along with their economic and environmental impacts, should be considered. The stability analysis for the planning and operation of HV, EHV, and UHV AC/DC grids in power systems is regarded as another key issue in modern power systems. Moreover, interactions between power converters and other power electronics devices (e.g., FACTS devices) installed on the network are other aspects of power systems that must be addressed. This Special Issue aims to investigate the integration of HV, EHV, and UHV AC/DC grids into modern power systems by analyzing their control, operation, protection, dynamics, planning, reliability, and security, along with considering power quality improvement, market operations, power conversion, cybersecurity, supervisory and monitoring, diagnostics, and prognostics systems.

System protection is laid between the defenses for power system protective relaying and the emergency control. Under the premise of ensuring the safety of electrical equipment, it strives to ensure the safety of the system, block the chain of occurrence and growth of cascading faults, and effectively avoid the occurrence of large-scale blackout catastrophes. This book systematically elaborates on the dealing technology of a special type of fault, the “cascading fault”, in the AC-DC hybrid large-scale power grid. The main contents include immunization distance protection for accident overload; distance protection that is immune to oscillation; inverter control technology to prevent long-term or continuous commutation failure; DC participation emergency power flow control technology used to share the accident transfer overload caused by inverter lockout; and overhead transmission line adaptive overload protection.The basis of English translation of this book from its Chinese original manuscript was done with the help of artificial intelligence (machine translation by the service provider DeepL.com).
