Literature first proposed the reconfigurable topology of the battery, in which the system reconfiguration could be achieved through five control switches per cell. In the series topology, each battery cell had only two controllable switches, which were used to connect other cells in series or bypass .
Traditional battery energy storage systems in industrial use have been largely restricted to DC based systems, and often limited in operation to a separate sub power network that does not directly interact with the main power network. Examples are 110 V DC UPS power networks, often reserved only for critical control and protection systems.
Recent advancements in battery technology, the economics of battery deployment, and increased power of automation and control systems, have enabled an emerging area of dynamic battery energy storage systems that can be interfaced directly to an AC grid.
The graph based algorithm was used to optimize the battery management system configurations for real time load requirements. Three switches per battery and two switches per pack have been used for reconfiguration . Furthermore, there are few researches on PCS topology at present.
The intended audience is project and design engineers who shall perform procurement and integration of such systems into both greenfield and brownfield electrical installations, as well as anyone who may have to interact with battery energy storage in a technical or professional capacity, including project managers and operational personnel.
While it is also common to find battery backed systems with an AC output, such as AC UPS systems, they are usually uni-directional, in that AC power is rectified, used to charge and float a DC link with battery energy storage, and this DC link then used to supply an inverter that feeds an AC network separate from the main AC power network.
