Voltage Stability Analysis in an IEEE 34 Nodes Test System with the Participation of Photovoltaic Generation Plants

This article describes a stability analysis in critical and generation nodes for an IEEE 34 topology that contains photovoltaic generation plants. The case studies the participation of photovoltaic plants is shown with 15% total generation of the system. The purpose of the case studies is to determine the range of stability that can be accepted in the proposed topology with the penetration of photovoltaic generation of the 15%, 25% and 50%, as well as to present the possible voltage variations, power drops and change in rotor angles in existing synchronous machines in the topology, in steady state as at the time of a failure.
