RoCoF-based sizing of Energy Storage System for Virtual Inertia support. Consideration of traditionally dismissed phenomena such as local frequency dynamics. Virtual Inertia support is offered as a coordinated effort across different power system areas. The method is validated in IEEE 9-bus system.
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.
This allows to distribute the inertia provision effort around the power system resulting in lower overall power and energy requirements for the energy storage. The validation is approached using the IEEE 9-bus system, then, the island of Santiago, Cape Verde is employed as a realistic study exploring its inertia needs.
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).
