  • Understand the grid synchronization process for solar PV inverters, ensuring phase, voltage, and frequency matching.
  • Study system behavior during synchronization, including start-up procedures and dynamic response to grid variations.

Power Flow Management, Net Metering, and Anti-Islanding Protection

Delve into advanced solar PV-grid integration scenarios and protective mechanisms:

  • Evaluate active, reactive, and apparent power flow between the PV system and virtual/actual grid.
  • Explore the implementation and operation of net metering, tracking energy import/export using dual power analyzers.
  • Demonstrate the anti-islanding protection mechanism in the event of sudden grid failure, using the virtual grid feature for safe and repeatable experimentation.

Technical Description

  • The system operates as a grid-connected solar photovoltaic platform, interfacing a PV source with the utility grid/virtual grid through a grid-tied inverter.
  • The inverter continuously executes Maximum Power Point Tracking (MPPT) to extract maximum available power from the PV source matching precise voltage, frequency, and phase synchronization to the utility grid.
  • Generated solar power is first utilized by the connected AC load at PCC; any excess power is exported to the grid through net-metering.
  • A variable capacitor and variable inductor load bank at PCC enables experiments related with transmission line inductance and power factor correction.
  • When solar generation is insufficient, the connected load automatically draws deficit power from the grid, demonstrating bidirectional power flow.
  • Integrated energy meters measure imported and exported energy, enabling net-metering and performance analysis.
  • The system continuously monitors grid parameters such as voltage, frequency, power factor, and harmonics.
  • Anti-islanding protection disconnects the inverter during grid outages or abnormal grid conditions to ensure safety.
  • Open and accessible terminals allow students to manually configure experiments, analyse inverter behaviour, and study grid interaction under varying operating conditions.
