Introduction

The global energy transition towards renewable sources such as wind, solar, and hydroelectric power was gaining momentum as part of efforts to reduce carbon emissions and combat climate change [1,2]. Renewable energy generation faces inherent challenges due to its intermittent nature, with power output fluctuating based on weather conditions and time of day [3,4]. To effectively integrate these renewable sources into the existing power grid, reliable energy storage solutions are essential [5,6]. Energy storage technologies enable the capture and storage of excess energy generated during periods of high renewable output, which can then be released when demand exceeds supply or when renewable generation was insufficient [7,8]. As such, these technologies are critical for ensuring the stability, reliability, and resilience of smart grids, which are becoming the backbone of modern energy systems [9-11]. The role of energy storage in smart grids extends beyond simply balancing energy supply and demand [12]. It contributes significantly to the optimization of grid operations, reducing grid congestion, and enhancing power quality [13,14]. Smart grids leverage advanced communication, control, and monitoring systems to enable two-way communication between utilities and consumers, allowing for more efficient management of electricity distribution [15-17]. In this context, energy storage technologies provide grid operators with the flexibility needed to maintain consistent power flow while accommodating the variability of renewable generation [18]. By storing energy during off-peak times and releasing it when needed, storage systems help mitigate fluctuations, ensuring a stable and reliable power supply [19-22].
