The county-scaled photovoltaic roof development pilot projects are encountering difficulties such as grid connection,insufficient local absorption capacity,and other technical problems.A new power system technology of"Photovoltaics,Energy storage,Direct current and Flexibility"(PEDF)is introduced.The opportunities and challenges of this new power system technology in solving the above two problems are analyzed to provide relevant suggestions.Advantages and economic benefits of the first rural PEDF low-voltage DC system in Dongyao village,Ruicheng County,Shanxi Province are analyzed in terms of new energy consumption,safety,and reliability.Besides,BIPV Center of China Energy is also analyzed for its PEDF technology,which makes use of its facade and roof to improve PV installed capacity,achieves on-site consumption,and realizes flexible energy supply and consumption.It is suggested that PEDF technology is one of the effective ways to solve the difficulties in grid connection and lack of local absorption capacity in large-scaled photovoltaic development.
