Non-Pll Direct Power Control For A Single-Phase Grid-Connected Three-Level Inverter, King Ademola Adebo

Master's Theses

The growing demand for clean, reliable renewable energy generation has led to the widespread adoption of solar energy as a source of electricity. Technological advancement aiding to reduce the cost of solar photovoltaic (PV) panels, as well as improvement in power electronics and control strategies for solar PV systems have also contributed to the growing popularity. For grid-connected solar systems to adequately meet future demand and grid requirements, the system must be reliable, and not affected by instability or distortions on the power grid.

In this thesis, a control strategy for single-phase grid-connected inverters that can synchronize to the grid …
