Abstract
New power electronic components or Balance of Plant (BoP) elements to increase short circuit power of battery energy storage systems (BESS), improving their capability to be integrated in the current protection scheme of distribution and transmission networks
Description
Lithium ion battery energy storage systems (BESS) are usually installed into power generation plants, distribution and transmission grids.
During the operation of power grids, short circuit events can occur, which are detected by specific protection devices, based on short circuit current flowing into the grid. Conventional systems to detect short circuit events are designed to measure very high current flows, due to the traditional nature of grid generators, with high short circuit current (typically 6-8 times In). However, power electronics used in BESS systems can manage only its nominal power and have no protective systems so, in case of a short circuit event they inject “In” into the grid leading to possible failure of protective devices.
Conventional systems are not suitable. Hence, the Seeker is looking for new power electronic components or Balance of Plant (BoP) elements to increase short circuit power of BESS, improving their capability to be integrated in the current protection scheme of distribution and transmission networks.
