Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations.
Control structures for grid-connected photovoltaic systems The DC–AC converters inject sinusoidal current into the grid controlling the power factor. Therefore, the inverter converts the DC power from the PV generator into AC power for grid injection. One important part of the system PV connected to the grid is its control.
In an effort to use solar energy effectively, a great deal of research has been done on the grid-connected photovoltaic generation systems. Fig. 2 shows the total PV power installed in the Europe, 98.7% correspond to PV grid-connected and only 1.3% for off grid. Fig. 2. PV power installed in Europe.
This example shows the operation of a photovoltaic (PV) residential system connected to the electrical grid. The PV strings section implements a home installation of six PV array blocks in series that can produce 2400 W of power at a solar irradiance of 1000 W/m2.
Apart from this, the control aspects of grid-connected solar PV systems are categorized into two important segments, namely, a) DC-side control and b) AC-side control. This article covers the important features, utilization, and significant challenges of this controller and summarizes the advanced control techniques available in the literature.
