Title: Power System Stability and Inertia Estimation Using Synchrophasor Measurements
Abstract: Wide-area monitoring of the power system is crucial for stable and flexible operation, especially considering dynamic characteristics, which are changing by the penetration of renewable energy sources. The talk gives the brief summary of methods to estimate the power system small-signal stability and the inertia based on the synchronized phasor measurements. Our developed method can estimate the stability and the system inertia based on the simple model based on the swing equation with the characteristics of dominant inter-area oscillations. The model can be derived from measured data with the appropriate signal processing without the detailed system information. The estimated effective inertia reflecting demand side resources will be useful for the cost effective RoCoF management.

Title: Intelligent Grid-Forming Control in Power Systems with High Penetration of Inverter-based Resources
Abstract: Modern power systems are experiencing significant and rapid growth in the integration of inverter-based resources, including wind power, solar photovoltaic systems, battery energy storage, and electric vehicles. While these technologies offer clean and flexible energy solutions, they do not inherently provide the physical inertia that traditional synchronous generators supply. This limitation becomes especially critical in grids with nearly 100% inverter-based resources, as it significantly alters system dynamics and increases the system’s sensitivity to small changes in load, generation, and disturbances. If not properly controlled, these fluctuations may lead to system instability or even blackouts. To address these challenges, grid-forming (GFM) converters are employed to manage inverter-based resources in a way that supports grid stability as they can provide essential functions such as frequency and voltage regulation, virtual inertia, islanded operation, and black-start capability. This presentation begins by explaining the importance of GFM converters. Then, a novel intelligent control method for GFM converters that can be applied to wind, solar, and battery systems, is proposed. Moreover, we a new idea on how inverter-based loads, such as electric vehicles, that can be controlled to support the power grid, is introduced. These concepts are demonstrated through results that compare the proposed methods with traditional control approaches under various system uncertainties and unexpected disturbances.
