Simplified distribution grid model for power quality studies in the presence of photovoltaic generators

摘要: Renewable energy sources are expected to have a considerable share in the global mix over next years and consequently further research is required enhance planning strategies, modify prudently existing standards set quality levels on delivered power order accommodate penetration of these technologies. Depending distribution grid dynamics load demand, amplitude voltage may vary significantly, therefore proper simulation models for performing dedicated studies. In this study, simplified accurate model representing introduced studies presence distributed photovoltaic (PV) generators. The proposed (SDGM) validated using measurements it then used along with verified PV system estimate variation capacity under investigation. Moreover, sensitivity analysis performed by varying parameters SDGM assess how altered. As last step, common regulation schemes analysed through use model, validating operational modes that can high capacities.
