A high-level block diagram of a grid-connected solar microinverter system is shown in Figure 4. The term, “microinverter”, refers to a solar PV system comprised of a single low-power inverter module for each PV panel.
This dependency leads to fluctuations in power output and potential grid instability. Grid-connected inverters (GCIs) have emerged as a critical technology addressing these challenges. GCIs convert variable direct current (DC) power from renewable sources into alternating current (AC) power suitable for grid consumption .
The inverter is a key link in the power electronic converter, which affects the power quality of entire microgrid 3. However, conventional inverter control methods can easily lead to poor control performance in complex engineering conditions, which can have adverse effects on the power quality of microgrids.
The grid-side inverter further processes the energy output to align with the grid’s frequency and voltage standards, facilitating smooth integration and enhancing the stability and reliability of the power 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.
This study presents a novel grid-forming inverter control strategy for resilient microgrid operations with bidirectional electric vehicle integration.
