Fault ride through concept in low voltage distributed photovoltaic generators for various dispersion and penetration scenarios

摘要: Abstract The Distributed Generation expansion and its smooth integration in distribution networks have gained much interest over the last years. Particularly, photovoltaic systems connected to low voltage networks, present noteworthy benefits for energy markets customers. Meanwhile, aiming high penetration level, many issues emerge regarding their behavior under grid disturbances. In this paper, concept of Fault Ride Through Capability (FRTC) is applied distributed generators (DG-PV), mostly coordinated design control interfacing inverters, so as successfully address FRTC requirements. These alterations are examined combination with an appropriate that improves FRT DG-PV units. order apply proposed control, storage system deemed indispensable. load flow analysis, impact interfaced reactance value XDG thoroughly investigated various dispersion levels scenarios. Therefore, by applying above concept, a suitable selection can be reached, achieving compliance limits without leading extremely inverter overloading (during faults). Finally, it shown wider units enhances compatibility.
