This work develops and evaluates machine learning methods for dynamic stability assessment of a power-system mathematical model, emphasizing adaptability through the proposed method’s lack of a priori parameters. The study targets emergency control under modern-grid conditions, where reduced inertia from renewables, stricter accuracy needs, heavy digitization, and large operational datasets complicate control. Ensemble models (XGBoost and Random Forest) estimate transient stability using IEEE 39 as a test system, achieving higher instability-classification accuracy when grid topology features are included.

A distinctive feature of the proposed method is the absence of a priori parameters of the power system model. Thus, the adaptability of the dynamic stability assessment is achieved. The selected research topic relates to the issue of changing the structure and parameters of modern power systems. The key features of modern power systems include the following: decreased total inertia caused by integration of renewable sources energy, stricter requirements for emergency control accuracy, highly digitized operation and control of power systems, and high volumes of data that describe power system operation. Arranging emergency control in these new conditions is one of the prominent problems in modern power systems. In this study, the emergency control algorithms based on ensemble machine learning algorithms (XGBoost and Random Forest) were developed for a low-inertia power system. Transient stability of a power system was analyzed as the base function. Features of transmission line maintenance were used to increase accuracy of estimation. Algorithms were tested using the test power system IEEE39 . In the case of the test sample, accuracy of instability classiﬁcation for XGBoost was 91.5%, while that for Random Forest was 81.6% . The accuracy of algorithms increased by 10.9% and 1.5%, respectively, when the topology of the power system was taken into account.

Introduction Application of algorithms based on machine learning (ML) in planning, operation, and control of power systems has become possible due to industry digitization and the collection of sufﬁcient amounts of data. The following problems are solved using ML algorithms: equipment monitoring [1], load forecasting [2], forecasting of renewable sources of energy (RES) [3], adjustment of power system control devices [4], state estimation [5], and disturbance detection [6] . However, in modern operation and control of power systems, the preference is still given to the conventional methods based on deterministic approaches. On the other hand, ML methods have evolved into effective tools in analysis and control of power systems in terms of time response, accuracy, and adaptability. In addition, the ever-growing use of phasor measurements [7] will signi
