Abstract: This paper epitomises the various aspects of virtual inertia using energy storage systems for satisfactory regulation against uncertain frequency and voltage fluctuations. Since the power system switches from a generator-dominated system to an inverter-dominated system it results in the culmination of lack of inertia due to the massive penetration of renewable energy resources. This eventually leads to problems of frequency stability and power quality. The principle of virtual inertia, which emulates the operation of the synchronous generator by providing the power system with inertia remotely, was a topic of research from 2007 and is now gaining recognition. Software simulations and hardware implementation will open the way for a thorough investigation of the technology in the future. Furthermore, it also addresses the different types of virtual inertia topologies, application with renewable energy sources, evaluation for ancillary services, potential opportunities, risks posed, and future research directions.
