        abstract = {The rapid growth of renewable energy technologies such as solar photovoltaic (PV) and wind power has significantly transformed modern electrical power systems. Although renewable energy provides environmental benefits and sustainable power generation, its large-scale integration introduces several challenges to grid stability and reliability. Unlike conventional synchronous generators, renewable energy sources are typically connected to the grid through power electronic converters, which provide limited inertial support and reduced fault current contribution. As renewable energy penetration increases, the overall system inertia decreases, which significantly affects system dynamics and stability. This review paper presents a comprehensive analysis of grid stability challenges associated with high renewable energy penetration. Key stability issues, including frequency stability, voltage stability, transient stability, and system strength, are discussed. Furthermore, various mitigation techniques such as grid-forming inverters, virtual inertia control, energy storage systems, and synchronous condensers are reviewed. A comparative analysis of selected research studies is presented to identify emerging technological solutions and future research directions. The findings highlight the importance of advanced control strategies and improved system flexibility to ensure reliable operation of renewable-dominated power systems.},
