“…However, analysts paid little attention to how transmission-level PV installations influenced utilities prior to the beginning of this decade. Features that separate associated PV facilities from traditional power facilities, including thermal, hydroelectric, or nuclear facilities, can be referred to as PV plants (Nasrazadani et al 2021). A power electronics interface connects a number of generators to the network in a large-scale photovoltaic endeavor.…”

Wind and solar energy production is intermittent and variable, causing voltage fluctuations in the power system. These fluctuations can affect supply and demand balance, leading to voltage instability. In some cases, integrating solar and wind energy can result in overvoltage or undervoltage conditions, which can negatively impact the power grid's operation. The research examines the effects and challenges of integrating wind and solar energy into power grids, concentrating in particular on issues with voltage stability. The investigation explores fundamental issues like voltage stability-based distributed power generation (DG) unit sizing and optimal locations, stability of voltage assessment and methods for enhancement. Experiments are conducted to examine the effects of energy storage devices, adaptive alternate current (AC) transmission lines, static caps and other electric components of the system on the stability of the voltage of the distribution and transmission networks. It provides a comprehensive examination of the technical difficulties, such as the stability issues associated with incorporating massive solar systems into the electrical grid. The research obtained results on technical methods to address the power instability challenges with the integration of solar power on a massive scale into the transmission system and its subtransmissions, known as the medium voltage distribution system.

“…In [13], the study analysed the system voltage stability before and after photovoltaic installation; however, the photovoltaic is not a replacement for the existing synchronous generator but an additional power generation. In [14]- [18], voltage stability analysis is conducted for a system with a photovoltaic inverter that generates reactive power, which does not follow standards, such as IEEE 1547, that prohibits actively regulating the voltage at the point of common coupling (PCC) [11]. Therefore, this study aims to examine whether installing a capacitor bank to compensate the reactive power, after a synchronous generator replacement with photovoltaic, can restore voltage stability level.…”

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