What is battery energy storage system (BESS)?

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.

Which multilevel topologies are used in power storage applications?

The cascaded H-bridge converter (CHB) and the modular multilevel converter with chopper or bridge cells (CC or BC) are two highly discussed multilevel topologies in power storage applications. The CHB converters, shown in Fig. 6, consist of several cells of single-phase H-bridge converters connected in series in each phase [35, 36, 37].

Which topologies are connected to a 13.8 kV/60 Hz grid?

All topologies are connected to a 13.8 kV/60 Hz grid. The 2 L and 3 L requires a power transformer to step-up the output converter voltage from 380 V to the grid voltage level. The MMC directly connected to the 13.8 kV grid without transformer. The MMC + ITX presents an insulation transformer (ITx) with turns ratio 1:1.

Why is Bess a good alternative to high energy consumption?

Since the energy price in the peak demand hours is typically more expensive, BESS has become an attractive alternative to companies with high electricity consumption during peak hours. BESS is usually controlled to charge at low demand hours and discharge at the critical time of demand [57, 58, 59];

What is the energy storage requirement for 2 L & 3 L converters?

According to , 2 L and 3 L converters have an energy storage requirement in the dc-link between 2 and 4 J/kVA. Therefore, both 2 L and 3 L presented equal stored energy requirements in the dc-link capacitor around 4000 J. For the inductor, the stored energy is 360 J and 1050 J for 2 L and 3 L, respectively.
