Abstract

In this paper, transient stability analysis is carried out on 39 bus systems. The wind and PV distributed generators are new to the 39 bus system. Transient stability of smaller Synchronous Generator units was studied in the presence of DGs. The power system under consideration receives power from a public utility and nine smaller captive power generators. The total active power load of the system is 121.57 MW, and the reactive power load is 56.6 MVAr Stability is assessed by obtaining Critical Clearing Times (CCTs). CCTs are calculated before and after placing DGs. Two solar power DGs and two wind DGs are introduced by suitably adjusting the active power outputs of existing synchronous generator units.    Stability analysis is carried out on seven load buses and ten generator buses. It is observed that CCTs of various faults are improved in the presence of DGs.  For the faults on generator buses, CCTs are improved by 15.7% on average, and for faults on load buses, CCTs are improved by 29.7% on average. The internal machine angle, voltage and frequency are plotted for various faults.
