In order to suppress the imbalance of DC microgrid bus voltage during power fluctuations, virtual inertial control is usually used in energy storage systems. This method increases the damping and inertia of the system, and achieves the effect of suppressing bus voltage fluctuations by slowing down the response time.
Energy storage systems (ESS) hold the potential to compensate for this lack of rotational kinetic energy with virtual inertia—such a system is called a virtual synchronous generator (VSG). The ESS is then sized accordingly to compensate for the lost inertia. The proposed method is demonstrated on the reduced Western System Coordinating

Incorporating energy storage as a virtual inertial course would require fundamental changes in grid operations and market design. Because grid rotational inertia is considered an inherent property of power generation, there is no market mechanism to include inertia generation as an ancillary service.
The inertia response of an energy system limits the rate of change of frequency, known as RoCoF, when a sudden change in load is encountered . Systems such as thermal energy storage and pumped hydroelectric have very little associated inertia and may be thought of as providing slow response energy storage.
Energy storage technologies have emerged as a viable alternative to providing inertia through virtual inertia, i.e. inertia generated or simulated with power electronics and controls (Zhao and Ding, 2018, Zhang et al., 2019, Fang et al., 2017a).
With a weighted score of 4.3, flywheels (with lithium–ion batteries a close second) appear as the most suitable energy storage technology to provide inertia for power systems.
Real inertia is distinct to emulated or synthetic inertia, and may be thought of as energy storage that acts in an entirely passive manner. That is to say, the transfer of energy is determined completely by the reluctance of the system to change speed.
