The advancement of a decentralized inverter-based strategy for voltage balancing effectively manages power imbalances in three-phase distribution networks by modulation of power injection based exclusively on real-time voltage readings taken at the Point of Common Coupling (PCC).
Abstract: For an AC-stacked photovoltaic (PV) inverter system with N cascaded inverters, existing control methods require at least N communication links to acquire the grid synchronization signal. In this paper, a novel decentralized control is proposed.
A recent paper co-authored by EIT’s Dr Hossein Tafti explores a distributed approach to inverter control, offering a practical path to more stable, resilient solar energy systems. The global shift toward renewable energy is pushing photovoltaic (PV) systems into a more prominent role on national grids.
The high phase margin confirms that the decentralized inverter control scheme exhibits strong robustness against disturbances and model uncertainties. This supports the observed rapid stabilization time (0.1 s) in simulation results and aligns with the system’s real-time control behavior.
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.
