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.
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).
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 present work focuses on the preliminary development of a novel energy storage system that makes use of real inertia to address short term supply/demand imbalances while simultaneously allowing for extended depths of discharge. The concept looks to combine flywheel and compressed fluid energy stores in order to power a synchronous generator.
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.
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.
The global solar storage container market is experiencing explosive growth, with demand increasing by over 200% in the past two years. Pre-fabricated containerized solutions now account for approximately 35% of all new utility-scale storage deployments worldwide. North America leads with 40% market share, driven by streamlined permitting processes and tax incentives that reduce total project costs by 15-25%.
