摘要：Voltage collapse is an undesired phenomenon that occurs due to voltage instabilityand is generally associated with weak or stressed system (heavily loaded lines), long lines,radial networks, faults and/or reactive power shortages. Its occurrence is not frequent indeveloped countries despite their large and complex networks but its frequency is high inEgypt. Voltage collapses are highly catastrophic anytime they occur. On the EgyptianInterconnected Electrical Grid EIEG, the system collapse phenomenon is frequentlyexperienced and often leads to either partial or total system collapse blackout, which greatlyimpairs the nation’s socio-economic development and industrialization. This high rate is due tothe fact that the EIEG is weak, highly stressed, long and radial in nature hence lackingflexibility. The analysis is performed for EIEG power system. Modern advances in technologyare changing the way utility industry increase the transmission of power throughout thecountry. Distributed energy resources are constantly improving their reliability and powercapabilities. The model analysis technique is performed for system using the constant loadmodel. The simulation results are Q-V curves on weak voltages by Power World SimulatorPWS Software and Matlab Program.
