The utility scale of non-conventional generators (NCGs), such as wind and photovoltaic (PV) plants, are competitive alternatives to synchronous machines (SMs) for power generation. Higher penetration NCGs has been respondent causing several recent incidents leading up voltage collapse in systems due the distinct characteristics under different operating conditions. Consequently, so-called syste...
