Reconfigured PV array performance of BIPV system in urban area under Partial Shading Conditions

Résumé

Partial shading Condition is responsible for most of the power losses in a PV system, especially in urban areas with high building density. Conventional configurations, Series-Parallel, Bridge-Link, Honey-Comb and Total-Crossed-Tied can mitigate these losses. Besides, physical array reconfiguration or electrical array reconfiguration can achieve better performance. This paper compares the performance of the four conventional configurations and two reconfiguration techniques for a homogeneous building district. Nine buildings are arranged uniformly in three rows and three columns, with the central building being the focus of the study. The areas studied correspond to the roof and a vertical (south) façade with a 5x5 PV array. The performance is evaluated by analyzing the daily energy losses on typical days in August (summer) and February (winter). With the data extracted from a database in Geneva, the results show that reconfiguration techniques can reduce the energy losses by 5% in August and 20% in February.
