Modular BESS designs allow for easier scaling and replacement of components, improving flexibility and reducing lifecycle costs. Designing a Battery Energy Storage System is a complex task involving factors ranging from the choice of battery technology to the integration with renewable energy sources and the power grid.
To address this challenge, battery energy storage systems (BESS) are considered to be one of the main technologies . Every traditional BESS is based on three main components: the power converter, the battery management system (BMS) and the assembly of cells required to create the battery-pack .

The PCS should be designed with this capability in mind. Peak Shaving: the battery energy storage system can discharge during periods of high demand to reduce peak load on the grid. The system should be sized appropriately to handle the expected peak demand reduction.
However, as the cell to cell imbalances tend to rise over time, the cycle life of the battery-pack is shorter than the life of individual cells. New design proposals focused on modular systems could help to overcome this problem, increasing the access to each cell measurements and management.
Fluctuations in electricity generation due to the stochastic nature of solar and wind power, together with the need for higher efficiency in the electrical system, make the use of energy storage systems increasingly necessary.
