Transitioning to a decentralized energy system
Ways to store renewable energy
Battery Energy Storage
Currently, the most promising technology for industrial and grid applications is electrochemical storage via battery. Over the last decade, lithium-ion batteries have emerged to cover a wide spectrum of energy storage applications, spanning a few kW to hundreds of MW and providing energy for just a few minutes or for many hours of continuous supply. Lithium-ion battery systems are made up of various elements:
- battery cells assembled in modules;
- battery racks connecting these modules to obtain the desired DC current; a containerized battery system made up of multiple racks connected in parallel;
- a power conversion system to convert a battery’s DC output into an AC output at mains voltage;
- and a customizable control system, spanning from a basic level to check parameters such as temperature and voltage, to more complex applications offering a further, smarter level of control, for example to optimize the economic side of a storage management system.
