Voltage stability analysis for the South-West Libyan electrical power system: Problem simulation and analysis

This paper discusses the simulation and analysis study of the South-West Libyan electric power system. The main problem facing this system is the frequent voltage sags and occasional power interruptions of the supply which adversely affect the customer's loads. The paper presents results of analysis and simulation for all possible contingencies that cause voltage instability on this part of the Libyan power system network.
