In the quest for a resilient and efficient power grid, Battery Energy Storage Systems (BESS) have emerged as a transformative solution. This technical article explores the diverse applications of BESS within the grid, highlighting the critical technical considerations that enable these systems to enhance overall grid performance and reliability.
Battery Energy Storage Systems (BESS) can be utilized to provide three types of reserves: spinning, non-spinning, and supplemental reserves. Spinning reserves refer to the reserve power that is already online and synchronized with the grid. It is the first line of defense during a grid disturbance and can be dispatched almost instantaneously.
Since battery storage systems do not have the mechanical constraints of traditional generators, they can provide non-spinning reserves more quickly and with greater precision. Supplemental reserves are typically the last to be called upon during a power supply shortfall.
