Our present study was performed using a GUI realized under MATLAB in our work.39202239202213203https://npublications.com/journals/energy/2022/a062009-003(2022).pdf10.46300/91010.2022.16.3https://npublications.com/journals/energy/2022/a062009-003(2022).pdfAli.Z.M, and ELsherbiny M.," effect of both mechanical and excitation system on power system and methods of improvement.", M.sc, Egypt, Assuit university,2003. 10.1016/s0142-0615(02)00124-2ABIDO, M.
