Battery Energy Storage Systems (BESS) play a crucial role in the modern energy landscape, providing flexibility, stability, and resilience to the power grid. Within these energy storage solutions, the Power Conversion System (PCS) serves as the linchpin, managing the bidirectional flow of energy between the battery and the grid.
Storage is used in PV systems to increase the amount of time that the PV system can be used to power a load. Batteries are the most common type of storage in a PV systems. However, in specific types of systems or applications, other storage components can also be used.
In more detail, let’s look at the critical components of a battery energy storage system (BESS). The battery is a crucial component within the BESS; it stores the energy ready to be dispatched when needed. The battery comprises a fixed number of lithium cells wired in series and parallel within a frame to create a module.
The EMS will also collect and analyze BESS performance data, making reporting and forecasting easy. These are the critical components of a battery energy storage system that make them safe, efficient, and valuable.
NGK Insulators, Ltd. has applied the NaS battery to MW class power storage. The NaS battery is used rather for industrial use because the battery is operated at 573K. For residential use, the Li ion battery with 7 kWh is commercialized.
Energy storage systems provide a wide array of technological approaches to manage our supply-demand situation and to create a more resilient energy infrastructure and bring cost savings to utilities and consumers.
