PEDF combination of four technologies of Photovoltaic, Energy storage, Direct current and Flexibility
Photovoltaic: Using the surface of buildings to develop photovoltaic power
Energy storage: Storage energy in charging pile or other energy storage devices
Direct current: Change AC into DC
Flexibility: Building electrical equipment needs to have interrupt regulation capability
Advantages
(1)High energy utilization ratio (6-8% higher than conventional PV buildings) and obvious energy-saving advantages
(2)Less equipment investment, short investment payback period
(3)Significantly improved system performance, security, and power quality
(4)Enhance the building electricity regulation ability (15%-30% regulating ability increased)
