Microgrid @ 萝莉社

 has partnered with 萝莉社 to develop a Renewable Energy Lab. The grant from Eevery provides real-time data from solar PVs and a substation for research and education at 萝莉社. The solar PV system includes eight different configurations of solar panels and 1-minute averaged data real from solar panels and the weather station. PMU data from substation along with a twin relay system in the lab will not only provide data but also will provide the necessary tools for hardware in the loop virtual microgrid. A schematic diagram of the solar system at 萝莉社 with eight configurations are shown in the figure.

Solar PV System Details 

  • Array 1: Standard string-inverter with 3.8kW solar generation capacity. Two strings of panels with separate maximum power point trackers for optional azimuth variation 
  • Array 2: Optimized string inverter with battery. Total installed solar generation capacity is 3.8 kW. Inverter is capable of demand response & load shifting. Installed capacity of the lithium battery is 9.8 kWh. 
  • Array 3: North facing solar array with micro-inverter. Total installed solar generation capacity is 1.9 kW. All eight solar modules are mounted at a nominal 0-degree azimuth angle.
  • Array 4: East facing solar array with micro-inverter. Total installed solar generation capacity is 1.9 kW. All eight solar modules are mounted at a nominal 90-degree azimuth angle.
  • Array 5: South facing solar array with micro-inverter. Total installed solar generation capacity is 1.9 kW. All eight solar modules are mounted at a nominal 180-degree azimuth angle.
  • Array 6: West facing solar array with micro-inverter. Total installed solar generation capacity is 1.9 kW. All eight solar modules are mounted at a nominal 270-degree azimuth angle.
  • Array 7: Dual axis solar trackers with micro-inverters. Total installed solar generation capacity is 1.9 kW. Four tracker each with two modules. 
  • Array 8: Partially shaded optimized string inverter. Total installed solar generation capacity is 3.8 kW. Shadows from building and an exhaust partially shade the solar panels, at different times in a year.
