In this work, Grid Forming (GFM) and Grid Following (GFL) inverter controls are developed for solar PV systems in a microgrid network. The different PLL techniques are tested in both a GFL and a GFM control-based inverter. The proposed models are tested in a microgrid test system and the results are validated.
The proposed models are tested in a microgrid test system and the results are validated. Using a proper resynchronization with PLL unit, the grid-connected solar PV with a Battery Energy Storage System (BESS) can be islanded and resynchronized with the main grid with less switching transients and faster resynchronization.
The grid inverter functions in two modes: as a front-end rectifier when transferring power from the grid to the battery, and as a voltage source inverter when feeding power from the PV/battery back to the grid. It incorporates a full-bridge PWM inverter with an LC output filter to inject synchronized sinusoidal current into the grid.
Notably, it excels in adapting to rapid load changes, maintaining active power at the specified reference while dynamically adjusting reactive power for voltage stability, which is ideal for MGs with dynamic load profiles. The inverters’ reference output voltages (Vref) are determined using a power flow analysis on the system.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
