Research on the Construction and Key Technologies of Wind-Solar-Storage Integrated Smart Grid

Under the global carbon neutrality strategy and the ongoing transformation of the energy structure, renewable energy sources such as photovoltaics and wind power are rapidly being integrated into the traditional energy system rely on their green and clean advantages. Given the intermittent and fluctuating nature of these new energy sources, energy storage technologies serve as a crucial “bridge”, balancing power supply and demand through peak shaving and valley filling. This has led to the emergence of wind-solar-storage integrated smart grid systems. This paper systematically reviews the core structure and key technologies of such systems, including the basic components of photovoltaic and wind power systems, advanced energy storage technologies, and intelligent control mechanisms. Additionally, by examining real-world application cases, it analyzes the effectiveness of these systems in various scenarios such as households, communities, and industrial settings. The study provides a theoretical foundation and technical reference for the optimized design and widespread application of wind-solar-storage integrated systems.
