“…EES has a wide range of essential application that can be applied to many different scales and fields.These applications range from larger generation and transmission systems to those that only focus on growing into the distribution network and even going "beyond the meter" to customer/end-user locations [9]. Numerous essential applications of EES have been identified and summarized in previous studies [7,28,29,42]. These applications encompass various aspects of the electricity system and include:…”

The surging electricity demand driven by a growing global population, coupled with the increasing electrification of industries, transportation, and power-intensive appliances, poses a substantial challenge to electricity systems worldwide. This challenge is further compounded by the pressing issue of climate change. To address climate change and mitigate the environmental consequences of fossil fuel use, renewable energy sources are expected to play a pivotal role. However, certain renewable sources, such as wind and solar, exhibit stochastic behavior, resulting in unpredictable power output and significant fluctuations. This intermittency presents a challenge in maintaining a stable and reliable power supply. To overcome this challenge and ensure a balanced electricity grid, the strategic deployment of energy storage devices throughout the power system becomes critically important. Energy storage technologies play a vital role in mitigating the mismatch between renewable power generation and consumption. Additionally, they enable the storage of surplus energy generated from renewable sources during periods of high production for later use during periods of low or no generation. Each technology possesses unique characteristics and applications, providing flexibility and diversity in energy storage solutions. This work provides an overview of different energy storage technologies and explores their role in establishing a sustainable power system.

“…It can be seen that potential applications of EES are numerous and various and could cover the full spectrum ranging from larger scale, generation and transmission-related systems, to those primarily related to the distribution network and even 'beyond the meter', into the customer/end-user site [13]. Some important applications have been summarised in [13][14][15], [32], [52], [62][63][64][65][66]: …”

THE PURPOSE. The relevance of research is that the comprehensive substantiation of issues aimed at ensuring the effective functioning of the electrical complex with the presence of an electric motor load in conditions of low-quality supply voltage. The aim of the work is to study the effect of the asymmetry of the supply voltage on the service life of an asynchronous motor with a short-circuited rotor. The main attention is paid to the dynamics of changes in the service life of low-voltage asynchronous electric motors of various series, depending on the level of voltage asymmetry. Asynchronous electric motors of the classic series (4A, AI) and the upgraded (5A, AI’) are identified as the object of research. As is known, the efficient and reliable operation of electric motors is characterized by the service life of the insulation of the windings. A qualitative assessment of the operational reliability of AM is determined by the accuracy of forecasting the real life of their service. That is why, it becomes obvious, the task of an adequate assessment of the operational reliability of low-voltage asynchronous electric motors operating under conditions of low-quality supply voltage directly depends on the complex of studies of such an external influencing factor as the asymmetry of the supply voltage. METHODS. The realization of the research objectives was carried out using the software package "SimPowerSystems" of the interactive programming environment Matlab/Simulink. RESULTS. The research was carried out on asynchronous motors with a short-circuited rotor: classic series (4A132S4, AIR160S8), upgraded series (5A132M6, AIR132S4) with PH = 7,5 kW, rated speed n = 1500 rpm. Modeling of the physical processes of the studied electric motors was carried out by changing the voltage asymmetry coefficient in the reverse sequence (K2U) from 0 to 5% in increments of 1%. Based on the obtained simulation results, diagrams of the change in the service life of AM from the magnitude of the influencing factor are constructed. The studies performed using computer modeling based on the "SimPowerSystems" software package of the Matlab/Simulink system made it possible to predict changes in the service life of AM, estimate the limits of permissible values of the voltage asymmetry coefficient in the reverse sequence, compare the studied electric motors by the level of resistance to an external influencing factor. CONCLUSION. A comprehensive solution to issues related to improving the operational reliability of low-voltage asynchronous electric motors is one of the priority areas, mainly aimed at ensuring the effective functioning of the electrical complex with an electric motor load. In the course of the study, a detailed assessment and analysis of the degree of influence of the asymmetry of the supply voltage on the operational reliability of low-voltage asynchronous electric motors was carried out. The results of the study were discussed, recommendations for the use of asynchronous electric motors in the presence of asymmetry of the supply voltage were formulated.
