چکیده :

The main purpose of this paper is to propose a novel approach to determine the maximum allowable penetration level of large scale photovoltaic power plants (LSPVPPs) considering rotor angle stability of power network. For this purpose, firstly, an algorithm for determining critical fault location (CFL) and critical clearing time (CCT) against three-phase faults in transmission lines will be proposed. Then, a novel algorithm will be proposed to determine the LSPVPPs penetration limit considering transient rotor angle stability. Also, the effects of different fault locations (FL) and the protection system operation time on the LSPVPPs penetration limit will be investigated. To show the performance of the proposed method and analyzing the factors affecting the penetration limit, LSPVPPs and their controllers are precisely modeled in the DSL environment of DIgSILENT PowerFactory software, and using the DPL environment of this software, the proposed algorithms are implemented on the Nordic32 test system. The dynamic simulation results verify the efficiency of the proposed method.
