Key Technologies for Protection and Control in Smart Grid

In response to the fossil energy crisis, the share of renewable energy within power systems has been increasing year by year. Consequently, smart grids are exhibiting new characteristics, such as deep coupling, a high degree of power electronics integration, and large-scale development and transmission. The transformation of energy structures and system architectures within smart grids poses challenges to system protection and control technologies. This session focuses on key protection and control technologies for smart grids. It will specifically explore critical protection and control techniques across the three nodal layers of the smart grid: generation sources, the transmission/distribution network, and loads. The scope of discussion covers various assets, including generating units, pumped storage units, renewable energy power stations, powertransmission lines, hybrid AC/DC systems, transformers, and distribution networks. The core objective is to analyze system fault characteristics and ensure the safe and stable operation of the smart grid. Topics of interest for this seminar include, but are not limited to: 

1. Fault Characteristic Analysis and Protection Technologies for Renewable Energy Transmission Systems

2. Adaptive Reclosing Technologies for Renewable Energy Transmission Systems

3. Coupling Analysis and Protection Technologies for Hybrid AC/DC Systems

4. Protection and Inrush Current Suppression Technologies for Large-Scale Transformers

5. Protection and Fault Localization Technologies for Renewable Energy Distribution Networks

6. Protection Synchronization and Novel Principle Technologies Utilizing Wireless Communication

7. Grid-Interfacing Protection Technologies for Large-Scale Generators in Smart Grids

8. Coordinated Control and Protection Technologies for pumped hydro storage

9. Stability Prediction Technologies for Renewable Energy Grid Integration Systems

10. Power System Stability Control Technologies Incorporating Renewable Energy Participation
