The challenges of large-scale energy storage application in power systems are presented from the aspect of technical and economic considerations. Meanwhile the development prospect of global energy storage market is forecasted, and application prospect of energy storage is analyzed.
Replacing centralized and dispatchable bulk power production with diverse small, medium-scale, and large-scale non-dispatchable and renewable-based resources is revolutionizing the power grid. The Energy Storage Systems (ESSs) have also been employed alongside RESs for enhancing capacity factor and smoothing generated power.
The development and commercialization of energy storage technology will have a significant impact on power system in terms of future system model . In recent years, both engineering and academic research have grown at a rapid pace, which lead to many achievements.
The application scenarios of energy storage technologies are reviewed and investigated, and global and Chinese potential markets for energy storage applications are described. The challenges of large-scale energy storage application in power systems are presented from the aspect of technical and economic considerations.
Intermittent sources act rigidly and their high penetration reduces the flexibility of the power system and may lead to new challenges related to energy quality , stability , and protection of the power grid. A variety of solutions are available to meet the challenges of integrating variable energy into the power grid.
The concerns about system stability have gradually increased with the increasing ratio of these emergent low-inertia technologies known as Inverter-Based Resources (IBRs), i.e., RESs and ESSs. The deficiency of inertia in future power systems due to the high penetration of IBRs poses some stability problems.
