Stability Region Analysis and Optimal Stability Control of Power Systems with Renewable Power Penetration
“新能源并网电力系统的稳定域刻画与稳定性优化控制”

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.
