Diagram of grid-connected photovoltaic system . The inverter, used to convert photovoltaic dc energy to ac energy, is the key to the successful operation of the system, but it is also the most complex hardware.
Grid-connected PV systems Grid-connected PV systems include building integrated PV (BIPV) systems and terrestrial PV systems (including PV power plants in saline-alkali land, tideland and desert). At the scale of the entire interconnected electric power grid, generated electric power must be consumed within milliseconds of being generated.
Grid interconnection of PV power generation system has the advantage of more effective utilization of generated power. However, the technical requirements from both the utility power system grid side and the PV system side need to be satisfied to ensure the safety of the PV installer and the reliability of the utility grid.
Grid interconnection of PV systems is accomplished through the inverter, which convert dc power generated from PV modules to ac power used for ordinary power supply to electric equipments. Inverter system is therefore very important for grid-connected PV systems.
Grid connected photovoltaic systems (GCPVS) are the application of photovoltaic (PV) solar energy that have shown the most growth in the world. Since 1997, the amount of GCPVS power installed annually is greater than that all other terrestrial applications of PV technology combined .
