Title of special session 1: Stability Region Analysis and Optimal Stability Control of Power Systems with Renewable Power Penetration

Biography of Organizers

Yang Liu, South China University of Technology, China

Associate professor, PhD supervisor, holds a Ph.D. from South China University of Technology and was a visiting scholar at the University of Liverpool in the UK. He has long been engaged in research on the solution of the transient stability domain of attraction of power systems and transient stability control methods. He proposed the structure-preserving dimensionality-reduction mapping theory for the attraction domain of high-dimensional systems, significantly improving the computational efficiency of the attraction domain boundary of large-scale systems. He put forward the distributed maximum transient energy control method and the stability proof method for general hybrid switching control systems, and pioneered the switching Lyapunov function stability theory for converters. He also proposed the maximum transient energy control method for power systems, solving the problem of rapid stability control of power systems under emergency fault conditions.

He was selected for the "Young Talent Support Project" of the Chinese Society for Electrical Engineering and was named one of the "100 Innovative Doctors and Post-doctors in Guangdong Province". He presided over the National Natural Science Foundation Fund, the Special Fund of the China Postdoctoral Science Foundation, the first-class funding of the General Project of the China Postdoctoral Science Foundation, the Guangdong Offshore Wind Power Joint Fund, the Basic and Applied Basic Research Project of Guangzhou, and the Fundamental Research Funds for the Central Universities. As the first author, he published a monograph by Springer and more than 40 SCI-indexed papers.

Tianhao Wen, South China University of Technology, China

Postdoctor, holds a Ph.D. from South China University of Technology. His research interests include transient stability analysis and coordinated adaptive control of large-scale renewable energy integrated power systems. He proposed a cascaded observer based nonlinear adaptive control strategy for multi-input multi-output systems with high relative degree. The proposed control strategy has been successfully applied to coordinated transient stability control of multiple wind-farms penetrated power systems, subsynchronous oscillation mitigation of series-compensated DFIG wind farms and robust adaptive control of MMC-HVDC systems
integrating offshore wind farms. In addition, he designed a sum-of-square optimization based domain-of-attraction estimation algorithm for nonlinear differential-algebraic systems. The algorithm can be used to estimate the entire transient stability region of structure-preserving power system models having significant transfer conductance and complex loads. Moreover, he put forward a switching control based distributed maximum transient energy control method, which has been implemented in rapid and effective stabilization of practical power systems suffering from severe disturbances or faults.

In recent years, he has published more than 10 SCI-indexed papers, one of which was awarded ‘the Excellent Paper of CSEE Journal of Power and Energy Systems in 2022’.

Brief description of the Special Session:
The increasing penetration of renewable power sources, such as wind and solar energy, into modern power systems has introduced significant challenges to system stability. Unlike traditional power generation, renewable energy is inherently intermittent and variable, leading to fluctuations in power supply and complicating the balance between generation and demand. These dynamics can destabilize power systems, causing voltage and frequency deviations, and even leading to cascading failures if not properly managed. As renewable energy integration continues to grow, understanding its impact on system stability becomes crucial for ensuring reliable and secure power grid operations. Stability region analysis plays a pivotal role in addressing these challenges by providing a comprehensive framework to assess the boundaries within which a power system can maintain stable operation under varying conditions. By analyzing the stability region, system operators can identify critical operating points, predict potential instability, and develop strategies to mitigate risks. This analysis is particularly important in systems with high renewable penetration, where traditional stability assessment methods may fall short due to the complex and nonlinear nature of renewable energy sources. Furthermore, optimal stability control is essential to enhance the resilience of power systems in the face of renewable energy variability. By leveraging advanced control algorithms and real-time data, optimal stability control can dynamically adjust system parameters, such as generator outputs and load distributions, to maintain stability within the desired region. This approach not only improves the system's ability to withstand disturbances but also maximizes the utilization of renewable energy resources. Together, stability region analysis and optimal stability control form a robust foundation for managing the challenges posed by renewable power penetration, ensuring the transition to a sustainable energy future while maintaining grid reliability.

Proposed topics: stability control, stability region analysis
