Abstract :

The goal of this study is to examine how synchronous generators that operate in tandem with photovoltaic (PV) power plants in a power system respond in terms of stability. Rotor angle, rotor speed, active and reactive power, terminal current response, excitation current response in the generator, and PV generator responses are the synchronous generator stability features that are measured. Six daily solar irradiation conditions—200 W/m2, 400 W/m2, 600 W/m2, 800 W/m2, and 1000 W/m2—as well as the state of the power system without PV generation—are used to replicate every facet of stability. An inverter is used in one of the substations to power the 10 MWp non-battery PV generator connected to a transmission line. The single-line graphic of the seven buses used to model this study on energy transmission lines.The existing transmission lines are supplied from two synchronous generator capacities, 100 MVA and 25 MVA. This result of this study shows that the high-penetration level of
