The energy technology sector is experiencing marked change from its traditional architecture of large-scale, centralized supply systems that take advantage of significant economies of scale. PV certainly fits this trend. Thus traditional cost comparisons based on large bulk power market may be misleading.
Solar photovoltaic power systems Solar photovoltaic (PV) power systems are a cornerstone of renewable energy technology, converting sunlight into electrical energy through the PV effect. This process takes place in solar panels comprised of interconnected solar cells, usually made of silicon .
In recent years, extensive research in form of experimental as well as simulation studies are being carried out on the application of PV systems as distributed energy sources (DERs) to harness power from the non-conventional energy sources with low environmental impacts.
Furthermore, the results of this study suggest that the integration of solar PV into existing wind power plants, although increasing the overall renewable capacity, it maintains the forecast errors in the range of the values previously observed in the wind power plants, and, in some cases, could enable to reduce the forecast errors.
A basic photovoltaic system integrated with utility grid is shown in Fig. 2. The PV array converts the solar energy to dc power, which is directly dependent on insolation. Blocking diode facilitates the array generated power to flow only towards the power conditioner.
