Stability Analysis of a Hybrid Power Plant: An Analysis through ETAP Software

Abstract—Transient analysis plays an important role in power system. Transient analysis is aimed at determining whether a system will remain in synchronism with other generating plants after disturbances. In this paper, transient stability for a small power plant (80MW) coupled with a small solar plant has been studied through ETAP software. The plant is operating as IPP (Independent Power Producer) and owned by United Power Generation & Distribution Co. ltd. (UPGD) under United Group, Bangladesh. Effect of fault on generating plant and solar plant side has been studied. In this paper our main aim is to show the effect of any type of fault on the power plant side is very low when fault occurs at solar plant side. The plant almost remains unhindered due to fault in the solar part of the proposed hybrid plant. Complete analysis has been done under ETAP software environment to predict the stability of the hybrid plant. As Bangladesh government is taking up a project to install MW range solar PV based plant that will be hooked up with the national grid, the present study will give an idea as to predict the behavior of the hybrid system especially as far as the stability of the overall system is concerned.
