Presented in this paper is a method of bidirectional real and reactive power control of a three-phase grid-connected inverter under unbalanced grid situations. Unbalanced three-phase load and unbalanced grid impedance are illustrations of unbalanced grid issues that have been investigated.
This project focuses on designing and simulating a three-phase inverter intended for grid-connected renewable energy systems such as solar PV or wind turbines. The inverter converts DC power from renewable sources into AC power synchronized with the grid, enabling efficient and stable integration of renewable energy into the electrical grid.
Abstract: Three-phase inverters for grid-connected applications typically require some form of grid voltage phase detection in order to properly synchronize to the grid and control real and reactive power. This phase detection is usually based upon some type of grid voltage sensing.
Integrating these into the conventional AC grid requires power electronics converters, particularly inverters that produce high-quality AC waveforms synchronized with the grid. This project simulates a three-phase inverter topology widely used in grid-tied renewable applications, focusing on efficiency and power quality.
Our photovoltaic 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.
