Power Topology Considerations for Solar String Inverters and Energy Storage Systems (Rev. A) As PV solar installations continue to grow rapidly over the last decade, the need for solar inverters with high efficiency, improved power density and higher power handling capabilities continue to increase.
Therefore, the key research directions of energy storage PCSs are high-voltage access, single-machine large capacity and modularization. Some scholars have proposed cascaded modular topology in terms of topology [5, 6]. The cascaded H-bridge (CHB) converter obtains the most attention and applications due to its good performance.
For the PV grid-connected system, references [19, 20] propose a topology based on isolated DC converters to meet the insulation requirements of photovoltaic systems connected to medium-voltage power grids. For the energy storage system, a high-frequency isolated topology is proposed, and the SiC-MOSFET module and prototype are developed .
Today this is state of the art that these systems have a power conversion system (PCS) for battery storage integrated. This application note outlines the most relevant power topology considerations for designing power stages commonly used in Solar Inverters and Energy Storage Systems (ESS). Figure 2-1.
In 2022, the South China University of Technology and State Grid Corporation of China proposed a PCS topology with an online bypass function based on H-bridge. They developed a 10 kV/2 MW medium-voltage direct-hanging energy storage converter . The above prototypes adopt non-isolated topology or power frequency isolated topology.
Assuming that there are four clusters of batteries in parallel, when the centralized PCS topology is adopted, BS is connected to the power grid through a PCS, and the system operating reliability is 0.9986.
