7.5MW Tracking Microgrid with Experimental Testing Sub-Array
Project Details
What made this project interesting?
The design for this project was highly detailed, and involved a significant level of coordination with the end-client, installers, and other engineering subcontractors. In terms of system characteristics, the most interesting aspect of this project was the experimental testing sub-array, which contains one 60kW inverter worth of single-axis tracking, fixed frame, fixed bifacial, and fixed frameless modules. Each 60kWp section of this sub-array is connected to its own 60kVA string inverter, and the performance of each system will be compared for demonstration purposes. Finally, due to the significant number of cables installed in trenches for the site, thermal deratings needed to be thoroughly considered during design. In this case, a thermal analysis software was used to create detailed models of trench cross-sections, and confirm that selected cable sizes were adequate for required loads
Key Learnings
Project management for utility-scale PV/battery systems.
Effects of thermal derating on current carrying capacities, and detailed modelling methods for trenching cross-sections.
