Review of Diverse Types of Fault, Their Impacts, and Their Solutions in Smart Grid

For effective operation of grid systems, it is important to understand the major types of power grid failures and the benefits of available renewable energy resources in the system during fault conditions. This paper surveys different types of faults that may occur in the power system, the underlying fault management approaches, offers diverse fault detection and localization techniques used for smart grid systems. Additionally, the impact of renewable energy resources on the stability of the system in the event of power failure is explored. The smart grid model in this paper investigates using Matlab/Simulink to determine the time needed to detect a power failure in the system, and to locate the faulty line by monitoring currents and voltages in the system. Presence of renewable energy resources and storage systems in the smart grid were found to play important roles in improving the reliability of the system.
