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).
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).
From this perspective, energy storage systems (ESSs) can help to balance demand and supply and control frequency, voltage, and power flows in isolated power systems or MGs operating in islanded mode.
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.
