The global transition to renewable energy sources is increasingly driving the development and integration of solar energy into smart grid architectures [1]. Solar energy, being one of the most abundant and environmentally sustainable resources, is playing a central role in modern energy systems. Smart grids, which use advanced communication and control technologies to optimize the generation, distribution, and consumption of electricity, are particularly suited to accommodate renewable energy [2]. The integration of solar power into the grid presents a range of challenges [3]. These include the intermittent nature of solar generation, the need for effective energy storage, and the complexities of managing decentralized energy production across diverse grid components [4]. As renewable energy adoption continues to grow, addressing these challenges becomes crucial for maintaining grid stability and ensuring the reliability of energy supply [5].
Smart grids offer a promising solution by utilizing real-time data and automated control mechanisms to improve the efficiency and resilience of energy systems [6]. In the case of solar energy, this requires sophisticated technologies to predict and manage fluctuations in generation [7]. The intermittent nature of solar power can lead to periods of excess generation during sunny days and energy shortages during cloudy or nighttime periods [8]. Effective energy storage solutions, such as batteries and other storage technologies, are essential for mitigating these fluctuations and ensuring a continuous power supply [9]. Integrating these storage systems into existing grids, which were primarily designed for traditional, centralized power generation, presents significant challenges in terms of interoperability and efficiency. The need for advanced energy storage solutions that can handle the dynamic requirements of solar integration is paramount to optimizing smart grid performance [10].
