NETWORK ARCHITECTURE HAVING PARALLEL REDUNDANCY FOR COMMUNICATION IN DC ENERGY STORAGE SYSTEMS

A power plant having a plurality of DC battery energy storage system (BESS) modules is disclosed, with each BESS module having a dually attached node (DAN); a plant controller; and a communication network. The communication network is linked between the plurality of BESS modules and the plant controller. The communication network includes a redundant local area network (LAN) arranged with a first LAN and a second LAN. The DAN of each of the plurality of BESS modules is in communication with the plant controller via the first LAN and via the second LAN. The communication network executes a parallel redundancy protocol (PRP) to effect communication between the plant controller and the plurality of BESS modules via the first and second LANs and the DAN.
