As the output of PV is not constant its influence on the power system stability needs to be considered and it is evident from the grid codes of most of the countries. In this paper two different model of solar photovoltaic generation suitable for small signal stability analysis are presented and its behavior is investigated considering the IEEE 14-bus test system. The research review the impact of solar power on the interconnected power system with a high penetration of PV generation by the control of active and reactive power output. Based on constant reactive power and constant voltage magnitude models, the effect of voltage and angle stability of grid connected PV systems are studied and discussed. The eigenvalue analysis is carried out for the test system without any PV penetration and with different PV penetration levels and the results are compared using the power system analysis toolbox on MATLAB platform. The most influencing critical modes are identified and their behavior with increase in PV penetration is demonstrated.Keyphrases: angle stability, eigenvalue analysis, photovoltaic generation, voltage stability In: Ajitkumar Shukla, J.
