Grid Connected Interactive Photovoltaic Power Flow Analysis: A Technique for System Operation Comprehension and Sizing

The progressive tendency, of the photovoltaic (PV) system connected to the electrical grid, is establishing new applications, in a way that, such system has to be optimised. Nowadays, many of these configurations start to bring benefits into the electrical network, such as: export/import of real and reactive powers, quick fix to shortages in power when used with storage equipment, active power mains harmonics filtering, and reduction of greenhouse emission and environment friendly power generation source. In this context, this paper deals with modelling and analysis of a grid connected PV system power flow, with the consideration of chain parasitic resistances and inductances. As a result, this leads to understand and infer various possible operating modes and system design concept
