| Abstract | The concept of distributed generation (DG) as a small-scale electric generator located near the load is becoming a very popular topic due to the rapid growing electricity demand, the shortage of conventional sources and the increasing concern over greenhouse gas emission. Renewable energy resources (RES) have been utilized and developed for DG technology to promote environmental friendly. Among those technologies, solar photovoltaic (solar PV), wind power and small hydro power are the renewable energy resources which grow faster than any other resources. Generally, small number of DG units will not influence power system operation. Thus, their impact can be neglected. However, the overall dynamics of power system will be affected when large amount of DG units are connected at higher capacity. In order to understand the system dynamic behavior, the stability analysis is needed to be studied. Small signal stability analysis is very much necessary to study the system oscillation when subjected to small disturbances. Therefore, the main purpose of this thesis is to investigate the impact of selected distributed generation (DG) on small signal stability in power distribution networks by using Eigenvalue analysis. The DG represents a solar PV and wind turbine system. The analysis has been carried out in two tested systems namely modified IEEE 13-bus test system and Thailand practical test system. Factors affecting DG operation such as wind speed, loading and DG penetration level are thoroughly investigated in this study. The modeling and simulation have been carried out by using MATLAB based power system analysis toolbox (PSAT) version 2.1.5. |
