Transient Stability Analysis of Large-Scale PV Penetration on Power Systems

Abstract

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.

Utilizing Hybrid Renewable Energy Systems for Enhancing Transient Stability in Power Grids: A Comprehensive Review

“…Chen et al [35] presented an urgent control strategy for system stability augmentation of system components with solar and hydropower plants utilizing the EEAC concept of equal-spanned area criterion. Almutiari and Rawa [36] examined the TS analysis of the actual network under three states: overloading the system, compensating the generator's power deficiency with a (Large Scale PV) LSP station, and replacing the SG with an LSP station. Hazari et al [37] proposed a Fuzzy Logic Controller (FLC)-based PV plant control system to improve LVRT efficiency TS.…”
