Dynamic Frequency Control Support by Energy Storage to Reduce the Impact of Wind and Solar Generation on Isolated Power System's Inertia. IEEE Trans. Sustain. Energ. 3, 931–939. doi:10.1109/TSTE.2012.2205025 Devold, H. (2013).
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.
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).
The allocation of energy storages for providing virtual inertia will not change radically the frequency trends in transient process, but the appropriate allocation of virtual inertia can improve the transient performance.
