Global energy needs are growing continuously, and there is now more focus on renewable energy sources. Solar Photovoltaic (PV) and wind have the major contribution among utility-level renewable energy sources. In India, till now gridconnected solar PV systems do not follow any specialized controls for grid support during disturbance and they isolate the solar PV system immediately with the help of anti-islanding technique. The paper presents a synchronous reference frame-based current control technique for solar PV inverters with low voltage ride-through control. A detailed performance analysis of grid-connected solar PV systems with and without low voltage ride-through control for various types of grid faults has been carried out. Various parameters like active and reactive power injection, circuit breaker opening time, dc-link voltage magnitude and voltage magnitude at the Point of Common Coupling (PCC) are recorded for symmetrical and unsymmetrical faults.


Among all energy resources, the importance of renewable energy is rapidly increasing and this trend is being seen globally. To reduce the greenhouse gas emissions and ensure security of energy for the future, it is important to reduce the use of fossil fuels and lessen our reliance on them. A viable way to resolve the current situation is to switch to renewable energy. Among the renewable energy sources, solar energy (particularly solar PV) and wind energy are the two important sources that are well established commercially and have proven technology for producing clean energy. The advantages of solar PV technology over other technologies include its small size, simplicity of installation, lack of mechanical moving parts, quiet operation, and low maintenance requirements. According to statistical predictions, the world' s solar PV installations will increase even more quickly in the future.
