Abstract

This paper presents dynamic analysis of multi-machine power systems with large penetration of Photovoltaic (PV) units. The actual non-linear characteristics of the PV-units is included in the modeling of the overall power system and the influence of this non-linear dynamics is studied through various simulations. These simulations (performed in MATLAB Simulink software package) are applied on a modified IEEE 30-bus system, where one of the major generators is replaced by a large PV power plant. Three case studies are considered. From these studies it is concluded that large penetration of PV-units deteriorates the dynamics of the overall system.
