In this work, the converter topologies for BESS are divided into two groups: with transformers and transformerless. This work is focused on MV applications. Thus, only three-phase topologies are addressed in the following subsections. .
Different control strategies can be applied to BESS [7, 33, 53]. However, most of them are based on the same principles of power control cascaded with current control, as shown in Fig. 8. When. .
The viability of the installation of BESS connected to MV grids depends on the services provided and agreements with the local power system operator. The typical services provided are illustrated in. .
Since this work is mainly focused on the power converter topologies applied to BESSs, the following topologies were chosen to compare the aspects of a 1 MVA BESS: 1. Two-level VSC with transformer (2 L + Tx), shown in Fig. 2; 2. Three-level NPC with transformer (3 L + Tx), shown in Fig. 4; 3. MMC, shown in Fig. 7(a). 4. MMC with. Power Conversion Systems (PCS) are critical components in energy storage systems. Acting as a “bridge” that switches electrical energy between direct current (DC) and alternating current (AC), PCS enable efficient charging and discharging of batteries for a wide variety of applications.

In Cuba, the electricity crisis has led to significant challenges in the power supply, with widespread blackouts and a severe deficit in electricity generation. The National Electric System is facing continuous disruptions, primarily due to breakdowns in thermoelectric units and a lack of investment in infrastructure23. As a result, the need for uninterruptible power supplies (UPS) has become increasingly critical, especially for businesses and essential services that require a reliable power source during outages5. However, the availability of UPS systems in Cuba may be limited due to economic restrictions and supply chain issues4. [pdf]
An energy storage system consists of three main components:a power conversion system, which transforms electrical energy into another form of energy and vice versa;a storage unit, which stores the converted energy;a control system, which manages the energy flow between the converter and the storage unit.

The capacity of outdoor power supplies varies widely, typically ranging from 100Wh to 2400Wh. Here are some key points to consider:Battery Capacity: Measured in watt-hours (Wh), it determines how much power the supply can provide. A larger capacity means longer battery life2.Types of Batteries: Common choices include ternary lithium batteries and lithium iron phosphate batteries, which affect the overall capacity and performance3.Power Supply Scenarios: The capacity should be selected based on the specific needs and scenarios, such as camping, emergency use, or powering devices4.Charging Speed and Output Ports: Consider the charging speed efficiency and the variety of output ports available for your devices4.These factors will help you choose the right outdoor power supply for your needs.
