A comprehensive review of grid-connected inverter topologies
This comprehensive review examines grid-connected inverter technologies from 2020 to 2025, revealing critical insights that fundamentally challenge industry assumptions
Grid-connected microgrids, wind energy systems, and photovoltaic (PV) inverters employ various feedback, feedforward, and hybrid control techniques to optimize performance under fluctuating grid conditions.
In the report, the communication and control system architecture models to enable distributed solar PV to be integrated into the future smart grid environment were reviewed. The existing communication technologies, protocols and current practice for solar PV integration are also introduced in the report.
The existing communication technologies, protocols and current practice for solar PV integration are also introduced in the report. The survey results show that deployment of communication and control systems for distributed PV systems is increasing.
Additionally, novel PV inverter control techniques ensure stable operation during unbalanced grid conditions using 4-leg NPC inverters, instantaneous active/reactive control, and hardware-based solutions. Table 16 provides a comparative analysis of these control strategies.
