Microgrid system and component evaluation: Mobile test platform with battery storage

This paper describes a mobile test unit designed to address challenges in deploying smart microgrid systems with battery energy storage. Despite the large body of knowledge around microgrid design and control, there is a limited understanding in the practical deployment and real-world operation of microgrids. The mobile and flexible test system has been built to better understand the operation and performance of microgrid systems and energy storage systems, and to provide a platform for advanced testing, training and research. The system is housed in a custom-built shelter containing a 273kWh Li-ion battery, 270kW bi-directional inverter, 350kVA isolating transformer, switchgear and protection systems required for grid connection. An advanced internet of things control system is used, and connects to the distribution network's control system. A flexible high-speed data acquisition and long-term data logging system captures power flow, power quality values, high resolution event waveforms, and environmental measurements.
