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.
Abstract Recent works have highlighted the growth of battery energy storage system (BESS) in the electrical system. In the scenario of high penetration level of renewable energy in the distributed generation, BESS plays a key role in the effort to combine a sustainable power supply with a reliable dispatched load.
The battery energy storage system (BESS) is the simplest ESS to design. The BESS is substantially less affected by environmental changes . HESS is typically used to handle such problems. HESS has a benefit over a single ESS in that it can efficiently use the characteristics of many energy storage technologies.
The BC can incorporate the battery and SC as HESS to alleviate the power imbalance between PV power and load demand. In addition to meeting the demands of the network operator, the proposed system also allows for the optimal functioning of a HESS integrated into a PV plant.
