Modeling and Dynamic Stability Analysis of Grid Following Inverter Integrated with Photovoltaics

The power transfer capacity of transmission lines is limited by the stability system. Additionally, dynamics photovoltaic (PV) integration through grid following inverter (GFI) affect limits, which are not well studied in literature. This paper, therefore, focuses on stability-constrained capabilities with single-phase PV-GFI integration. An adaptive tuning method proposed based Lyapunov function analysis that increases capability limit. Outer and inner control loop parameters considered as candidates for method. law affected active reactive requirements, low-voltage or over-voltage ride-through, network impedance, load changes. an damping utilizing a capacitor voltage feedback to eliminate effect resonance improved quality. validated simulation experimental verification various test scenarios, such sudden changes solar irradiance, dynamic changes, parameter variation, sag-swell conditions. achieves enhanced limit compared existing
