Test Specification 02.01

Test Rationale

N/A

Specific Test System

Laboratory setup

Target measures

Inverter power injection, load voltage and frequency, inverter currents

Input and output parameters

Input:

• Load
• Inverter power injection set-points
• Grid conditions Output:
• Power, voltage, current and frequency measurements

Test Design

1. Operate multiple inverters in parallel
2. Perform a network fault when the microgrid operates either in islanded (non-interconnected) mode or in grid-connected mode
3. Save the experimental results

Initial system state

• Inverter controllers enabled
• Hardware or simulated network and devices up and running
• Computer displaying and saving data

Evolution of system state and test signals

The system goes from normal operation (operation close to nominal voltage and frequency) to operation under grid faults, to test the inverter control algorithms

Other parameters

N/A

Temporal resolution

N/A

Source of uncertainty

Impedance of load and lines, inverter sensors operation

Suspension criteria / Stopping criteria

Abnormal current/ power injections from inverters
