Voltage Stability Analysis of Power System with Photovoltaic Power Plant

Photovoltaic power plants usually do not provide reactive output; hence the application of large photovoltaics in systems will decrease voltage stability level system. Capacitor banks can to compensate photovoltaic plants; therefore, capacitor overcome deficiency plants. However, effect bank installation on system’s is unknown. Therefore, research aims investigate whether installing a capacitors restore system stability. The study employs method Voltage Stability Margin and transient simulation IEEE 9 bus modified where one generator replaced with plant, also installed. results show that lower than original When capacity increased maximum allowable value, rises. it still unable be restored its value.
