Abstract	The rapid growth of solar photovoltaic (PV) deployment is accelerating the transition from conventional power systems to smart grids. Although solar energy offers significant environmental and economic advantages, high PV penetration introduces several operational and technical challenges, including voltage fluctuations, frequency instability, power quality degradation, protection coordination issues, and reduced system inertia. Smart grid technologies supported by advanced communication, automation, and intelligent control provide effective solutions to these challenges. This paper presents a comprehensive review of the impacts of solar energy integration into smart grids and systematically analyzes mitigation techniques reported in the literature. Smart inverters, energy storage systems, demand response, artificial intelligence–based optimization, and microgrid architectures are discussed along with standards and global trends. Research gaps and future directions are highlighted to support reliable and resilient smart grid operation.
Keywords	Solar PV integration, smart grid, voltage stability, energy storage, demand response, artificial intelligence, microgrids.
