“…Also, the bus voltage recovered more speed during PV penetration than the base case where there is no PV. The voltage control scheme in the LSP plant acts fast in comparison to the conventional voltage control scheme of the synchronous generator [21].…”

With the continuous expansion and upgrading of power networks, most countries tend to exploit the renewable energy sources available to them to facing the increasing of system load or to compensate the power shortage in the system or to replace the conventional generator (SG) by large scale photovoltaic (LSP) plant. This paper deals with a representation of a real network using the powerfactory DIgSILENT program to examine the transient stability analysis of power grid under three cases, increasing of the system load, compensation of the power shortage from the generator with LSP plant and replacement of the SG by the LSP plant. The different level of the LSP penetration are considered in some assumed cases to examine the variation of the rotor angle and bus voltage after a three phase fault. The results of the transient stability analysis have been plotted and presented.

“…Low solar irradiance directs the real part of the critical value to the right side of the complex plane and leads to a high proportion of instability on the system with high gains of the current regulator and the impedance controller. A systematic methodology [24] was proposed to explore the stability of the rotor angle when the PV integration is high and maintaining steady-state system parameters with solar PV integration. These parameters include AP, RP, and the difference in the maximum angle of the rotor.…”

Renewable energy systems (RESs), such as photovoltaic (PV) systems, are providing increasingly larger shares of power generation. PV systems are the fastest growing generation technology today with almost ~30% increase since 2015 reaching 509.3 GWp worldwide capacity by the end of 2018 and predicted to reach 1000 GWp by 2022. Due to the fluctuating and intermittent nature of PV systems, their large-scale integration into the grid poses momentous challenges. This paper provides a review of the technical challenges, such as frequency disturbances and voltage limit violation, related to the stability issues due to the large-scale and intensive PV system penetration into the power network. Possible solutions that mitigate the effect of large-scale PV system integration on the grid are also reviewed. Finally, power system stability when faults occur are outlined as well as their respective achievable solutions.

“…Damping of inter-area mode was found to be decreased due to impact of inverter-based generation on the small signal stability [4]. The authors in [5] has revealed the impact of both utility-scale and roof-top PV on power system transient stability of a large test system. The conclusion shows that solar PV could have both negative and positive impact on the transient stability of the system depending upon the fault location and the duration of fault.…”
