2. unctions of Power Conversion Systems (PCS) in a Battery Energy Storage System (BESS) Bidirectional Conversion: The primary role of PCS is to convert the DC power generated or stored in the batteries into AC power that can be fed into the grid. Similarly, during charging, it converts incoming AC power into DC for storage in the batteries.
Power electronics and battery cells are considered when examining the dependability of energy storage systems. Two BESS configurations, a fully rated 2 L converter, and four partially rated 2 L converters were all compared.
Additionally, the DC voltage can be managed by adding an additional DC-DC converter between the battery and the DC-AC converter connected to the grid. However, the additional conversion step increases complexity, raises costs, and may result in further power losses.
To ensure a highly efficient DC-AC conversion, the rated AC voltage should be kept as high as possible to reduce current stress in the semiconductors, which is the main cause of loss in the power electronics converter. A two-level (2L) VSC, a three-level T-type NPC converter, or an ANPC converter is the most widely used option.
