Power electronics-based converters are used to connect battery energy storage systems to the AC distribution grid. Learn the different types of converters used. The power conditioning system (PCS) only makes up a small portion of the overall costs for lithium-ion and lead-acid battery-based storage systems, as shown in Figure 1.
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.
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.
Also, consider the restrictions and requirements for safety, harmonic content, and P-Q capabilities established by technical standards and national grid codes. Power electronics converters can first be categorized according to whether or not a step-up transformer is used.
However, the PCS's share of costs will increase due to the falling prices of battery cells, as shown in Figure 2. In this light, it is wise to design the power electronics converter for maximum efficiency and dependability, thereby lowering the total cost of ownership. Figure 1.
