With the growth of distributed generators in power grid, replacing fossil‐fuel‐based conventional generation sources with renewable resources, namely photovoltaics (PVs) or wind turbines, is inevitable. However, when rotating‐kind synchronous machines that usually possess high inertia are replaced by PVs have an inherent static nature, grid stability issues such as reduced system inertia, lack reactive power, and decreased damping may arise. This study investigates impacts high‐PV penetration Texas 2000‐bus network. From impact analysis conducted under transient conditions, it observed could negatively adversely affect voltage frequency which mainly due to replacement results network support. Hence, alleviate adverse implications on systems a long‐term generator scheduling strategy proposed considering criticality for optimally decommitting generators. Extensive case studies determine ideal dispatch test based criterions.
