Power System Protection

Dear Colleagues,

Power system protection has been a critical topic in research and the power industry, as it reduces maintenance costs due to system failure, allows the power supply to continue feeding the parts of the system that are not affected by the fault, and ensures personnel safety. Power system protection can be discussed from various perspectives, such as: protection in high-voltage (HV) transmission networks, protection in low-voltage (LV) distribution networks, protection in communication services and cyber security, protection in modern power plants, protection in hybrid renewable energy systems, etc.

The present Topic aims to create a representative and updated collection of reviews or regular research articles on the challenges and developments associated with power system protection. The "Power System Protection" Topic includes, but is not limited to, the following areas:

• Transformer protection;
• The protection of synchronous generators;
• Transmission line protection;
• Digital and adaptive relaying;
• Protective devices, systems, and technologies;
• Types of protection;
• High-voltage transmission network protection;
• Overcurrent relay;
• Distance (impedance relay);
• Earth fault;
• Arc flash;
• Low-voltage networks protection;
• Disturbance-monitoring;
• Micro-grids and islanded networks protection;
• Grid codes and policy/legislative issues that may impact protection;
• Protection of energy storage and novel loads;
• Protection against network instability and low inertia;
• Protection of conventional and renewable generation and grid interconnections;
• Fault detection and localisation techniques;
• New protection algorithms and software solutions;
• Design and application of substation communications and integrated systems;
• Advanced signal processing techniques applied to protection systems;
• Multi-agent-based protection systems;
• Wide-area protection systems;
• Big data and cloud computing;
• Cyber security;
• Testing procedures and tools.
