Introduction

Smart grids are emerging as a critical solution to address the challenges posed by renewable energy integration [1]. Unlike traditional grids, smart grids incorporate advanced communication, control, and monitoring systems that enable real-time data collection and dynamic response to changing grid conditions [2,3]. Through these innovations, smart grids can manage the variable nature of renewable energy sources more effectively [4]. Technologies such as Energy Storage Systems (ESS), Demand Response (DR), and DERs offer essential tools for balancing supply and demand [5,6]. These systems provide the flexibility needed to integrate renewable energy while ensuring grid stability [7]. The capability to store excess energy during periods of high renewable generation and release it during peak demand or low generation periods was a cornerstone of smart grid functionality, enabling a more resilient and reliable power supply [8,9]. Energy Storage Systems (ESS) play a vital role in ensuring that renewable energy sources are utilized efficiently by storing excess power when generation exceeds demand [10-13]. ESS helps smooth out the fluctuations in renewable energy generation by absorbing energy during times of abundance and releasing it when renewable output was low or demand was high [14-16]. This ability to store and dispatch energy ensures that renewable power can be harnessed and used optimally, reducing reliance on conventional fossil-fuel-based power plants [17]. Technologies such as batteries, pumped hydro storage, and flywheels have varying capabilities depending on the duration and capacity of energy storage required. By optimizing ESS, grid operators can manage the intermittency of renewable energy, thus enhancing the overall efficiency of the grid and reducing operational costs [18]. ESS contributes to reducing carbon emissions by lowering the need for backup power from fossil-fuel plants, aligning with sustainability goals [19].
