Lab Information and Equipment

The Advanced Power System Laboratory (APSL) is highly flexible and is the first of its kind in Hawai‘i — able to test AC and DC equipment, systems, and microgrids within a representative and tightly controlled electrical environment. Major components of the lab include a 35.3 kW rooftop PV system connected to four advanced PV inverters equipped with grid support functions serving three AC/DC equipment test bays. The architecture also includes a real-time grid simulator connected to a 30 kVA power amplifier. This power hardware-in-the-loop (PHIL) configuration can evaluate electrical power equipment as units under test (UUTs) in a real-time simulated grid environment. This architecture is shown in the figure below:

The lab includes three modular test bays that can be used to evaluate the advanced functions, communications, and controls of various UUTs such as:

  • Advanced function PV inverters;
  • EV chargers, including vehicle-to-grid (V2G), vehicle-to-home (V2H) enabled chargers;
  • Battery energy storage systems (BESS);
  • Power monitoring and edge computing device;
  • AC or DC loads/appliances and load control devices; and
  • Voltage management devices.

Each of the three test bays are equipped with outlets rated at different voltages (3Φ 208Y/120 V grid-tied, 1Φ 240/120 V grid-tied, 3Φ 0~520 VLL Grid Simulator, and 600 VDC off-grid).

The AC test beds provide access to the following three AC test buses:

  • 1Φ/3Φ 0~520 VLL AC grid simulator bus served by the Chroma 61830 grid simulator;
  • 3Φ 208Y/120 V AC bus served by a 225kVA transformer; and
  • 1Φ 240/120 V AC bus served by a 100kVA transformer.
