Abstract: This paper aims to investigate the effective integration of renewable energy sources, such as solar and wind energy, into intelligent distribution networks and address the challenges posed by their inherent instability and volatility. We begin by introducing the definitions and characteristics of renewable energy sources and intelligent distribution networks, along with their interrelationship. Subsequently, we explore the challenges associated with renewable energy integration, including instability and volatility, grid capacity and renewable energy penetration limitations, complexity of scheduling and operations, and cross-regional integration issues. We then focus on the role of energy storage technologies in renewable energy integration, including battery storage, pumped hydro storage, and thermal energy storage. We analyze the advantages and application scenarios of these technologies and discuss how they mitigate the fluctuation of renewable energy, improve utilization efficiency, and enhance power supply reliability. Furthermore, we present various methods and technologies to address the challenges of renewable energy integration, including high-precision renewable energy forecasting and scheduling methods, optimization control strategies for energy storage systems, intelligent management and optimization algorithms for distribution networks, and the support and encouragement of electricity markets and policies. Lastly, we provide insights into the future directions of renewable energy integration and intelligent distribution networks, encompassing technological innovations and research areas, the importance of policies and regulations, as well as the commercialization and market prospects. The findings of this paper have significant theoretical and practical implications for promoting the development of renewable energy integration and intelligent distribution networks, thereby realizing clean, reliable, and efficient energy supply.
