An economic assessment of the residential PV self-consumption support under cost-reflective grid tariffs(PPT)

摘要

1.Developement of photovoltaic(PV)panels has been encouraged by Feed-in tariffs(FIT)in France.2.2016: French government implemeted a regulatory framework to encourage photovoltaic(PV)self-consumption.3.2021 in France: Time-of-Use network tariffs applied to 80% of residential customers.3.1 Purpose: to better reflect each network user’s contribution to network costs 4.But Time-of-Use tariffs decrease the profitability of PV self-consumption(O’Shaughnessy et al.,2018)because: 4.1 Higher tariffs occur at night and during winter whereas the PV production is diurnal.4.2 Households are not willing to shift most of their consumption(Palm and al,2018).5.Batteries can improve the profitability of PV self-consumption but FITs hinder the investiment batteries : Barbour et Gonzalez(2018),Kaschub,Jochem,and Fichtner(2016),Sani Hassan et al(2017).6.Issues with the current French policy : 6.1 costly due to the FIT.6.2 hinder battery investments while this technology could bring benefit to the grid.6.3 is inappropriate to challenge the future development of Time-of-Use tariffs.
