Abstract: This paper presents a study for a power system restoration plan for the Electricité Du Laos (EDL) power system in Southern area of Lao’s People Democratic Republic (Lao PDR) that utilizes available hydropower generation. Transient analysis is used in studying frequency and voltage fluctuations during the power system restoration process. DIgSILENT PowerFactory software is used as a tool to simulate the power system. Simulation results can be used to formulate guidelines for a safe and efficient restoration procedure of power system. The result of this research can assist the power system operators and planning engineers to set the plans for power system restoration in the case of a blackout.

Keywords: Blackout, DIgSILENT PowerFactory, power system restoration, restoration planning
