With the rapid growth of power market reform and power demand, the power transmission capacity of a power grid is approaching its limit and the secure and stable operation of power systems becomes increasingly important. In particular, in modern power grids, the proportion of dynamic loads with fast recovery characteristics such as air conditioners, refrigerators, and industrial motors is increasing. As well as there is an increasing proportion of different forms of renewable energy in power systems. Therefore, the short-term voltage stability (STVS) of power systems cannot be ignored. This article comprehensively sorts out the STVS problems of power systems from the perspective of data-driven methods and discusses existing challenges.

“…The development of Phasor Measurement Units (PMUs) and Wide Area Monitoring Systems (WAMS) in the late 20th and early 21st centuries marked significant progress in the ability to monitor system stability in real time and respond proactively to disturbances (Xianzhong, 2006). Additionally, the integration of renewable energy sources and distributed generation has prompted the need for revisiting traditional stability concepts and developing new frameworks to address the unique challenges posed by these technologies (Kim et al, 2021). These advancements reflect the ongoing evolution of stability analysis techniques and the continuous adaptation of power system stability concepts to meet the demands of modern and future power grids (Shamim, 2022).…”

“…The existing literature also reveals conflicting findings and ongoing debates that further highlight the need for continued research. For instance, while some studies suggest that advanced control techniques and smart grid technologies can effectively mitigate stability issues introduced by DERs, others argue that these solutions may not be sufficient under all conditions, particularly in regions with very high renewable penetration (Kim et al, 2021). There is also debate regarding the most effective regulatory frameworks and policies to support DER integration while ensuring grid stability.…”

The increasing penetration of distributed energy resources (DERs) into power systems has transformed the landscape of energy distribution, bringing both opportunities and significant challenges. This study examines the impact of DER integration on power system stability, focusing on voltage stability, frequency stability, and transient stability. A comprehensive review of 50 high-quality studies from peer-reviewed journals and reputable conference proceedings was conducted, utilizing advanced modeling, simulation, and empirical analysis methods. The findings reveal that the intermittent nature of renewable DERs, such as solar and wind, leads to voltage fluctuations, necessitating advanced control strategies to maintain stability. Additionally, the displacement of traditional synchronous generators by inverter-based DERs reduces system inertia, posing severe frequency stability challenges that require innovative solutions like synthetic inertia and fast frequency response mechanisms. Transient stability issues are also exacerbated by DER integration, highlighting the need for advanced inverter controls and enhanced fault ride-through capabilities. Energy storage systems (ESS) are identified as crucial for buffering the variability of renewable DERs, providing essential services such as frequency regulation and voltage support. However, high costs and scalability issues remain barriers to widespread ESS adoption. The study underscores the importance of supportive regulatory and policy frameworks in facilitating the seamless integration of DERs while maintaining grid stability. Effective policies that promote smart grid technologies and DER-friendly regulations are essential for ensuring a stable, resilient, and sustainable power grid. This research contributes to a deeper understanding of the complex dynamics introduced by DERs and offers insights into developing robust strategies to address stability challenges in modern power systems.

“…One of the major sources of uncertainty in power systems is the composition of the load. Since in normal scenarios the mixture of load is not known with precision, we wish to understand how system trajectories under a disturbance vary with the change of the mixture combination [17]. In other words, we would like to know how sensitive the system is to a variation of the load mixture in a set of buses.…”

In this work we present a novel technique, based on a trust-region optimization algorithm and second-order trajectory sensitivities, to compute the extreme trajectories of power system dynamic simulations given uniform parametric uncertainty. We show how this method, while remaining computationally efficient compared with sampling-based techniques, overcomes the limitations of previous sensitivity-based, worst-case trajectory approximation techniques, when the local approximation loses validity because of the nonlinearity. We present several numerical experiments that showcase the accuracy and scalability of the technique, including a demonstration on the IEEE New England test system.
