Abstract: A simulation analysis is performed on the operational performance of distributed PV systems connected to distribution networks. Firstly, the topology of distributed PV system is analyzed. And then the operational model of PV module and PV inverter is established according to the operational mechanism of key components of PV system, and the shadow occlusion model of PV modules is established according to the I-V characteristics of PV modules. Finally, combined with the field test results, the operational model parameters for the PV system are determined. The operational performance of the distributed PV system can be evaluated with the structure and PV modules of PV system.

Key words: PV generation, PV module, PV inverter, shadow occlusion
