Real-time simulation and hardware-in-the-loop tests of a battery system

In this paper, a real time model of the microgrid with an energy storage system has been implemented in RT-Lab. Coordinated control of the battery storage system with a PV system is simulated. To be more realistic, hardware-in-the-loop (HIL) testbed has been implemented with a real battery cell (3.2-V, 40-Ahr) connected to the real-time simulation model of the microgrid. A programmable current source (Magna) and programmable load (Bk 8500) have been used to create charging and discharging paths between the energy storage unit and the RT-LAB.
