主　　题：photovoltaic renewable energy sources power protection voltage profile fault ride-through 

摘      要：The energy market in Libya is expected to face substantial changes in the next few years:electrical energy consumption will increase by 50% within the next 4 ***,there is a plan to gradually increase renewable energy sources in the power network by 2030 to 30%.Solar photovoltaic(PV)plants will play a significant role in the energy transition and the mix of energy sources in *** article is a study conducted to investigate the challenges of power-flow management and power protection from integrating PV power plants into the Libyan power *** particular,a simulation model is built for the Kufra PV power plant(10 MW)with eight buses to assess the power network performance in terms of power quality such as voltage profile,power losses and ***,the impact of the PV plant on the short-circuit level and the power-protection system is presented under different operating *** fault ride-through(FRT)is operated using standard ambient temperature and a wide range of irradiation intensity,and is verified by using the Libyan grid *** results show that the integration of the PV plant into the grid has a significant impact on the short-circuit level and the FRT over the different fault levels and locations on the *** initial period of the three-phase fault shows that the PV plant will be disconnected from the grid due to a decrease in the root mean square value voltages where the reactive and active power of the grid reach 938 MVAR and 261 MW,*** results show that increasing the fault level will lead to an increase in injecting the active *** work is considered the first extensive investigation into the challenges of modern power-flow management and power protection for the power network system in Libya.
