Abstract

The purpose of this project is to identify the effect of high penetration level of solar energy on small signal stability of a power system. With the growth of renewable energy development, the problems with high penetration level of renewable energy can no longer be ignored. The replacement of conventional generator with renewable energy generator has been taking placed in the power system generation as the non-renewable energy continue to deplete. Other than that, the final products excreted from non-renewable energy increased the pollution. With the level of penetration that currently exist, the small signal stability had no issues to be solved. The problem comes with high penetration level of solar. This was stated in terms of solar energy generation. Other than small signal stability, the issues will also come in terms of transient stability or large signal stability. The project focused on small signal stability as the previous studies showed conflicting results that need to be further investigated. A suitable power system had been chosen as a test system. The simulation was conducted by using two software which are Power World Simulator and MATLAB/Simulink. The analysis is based on characteristic system response. The penetration levels of solar energy were PV varied to see the characteristic response of the system. The high penetration level of solar may not have significant impact on small signal stability of power system based on the simulation.
