Parallel Inverters Using Virtual Synchronous Generators with Fuzzy Logic Controller in Micro Grids

Authors(2) :-G. Krishnaiah, Atchi Ram Babu

Virtual synchronous generator (VSG) control is a promising correspondence less control strategy in a microgrid for its inertia support highlight. Be that as it may, active power transients also, despicable transient active power sharing is observed when fundamental VSG control is connected. Also, the issue of reactive power sharing mistake, acquired from traditional droop control, ought to likewise be routed to acquire attractive stable state execution. In this paper, an upgraded VSG control is proposed, with which transient damping and genuine transient active power sharing are accomplished by changing the virtual stator reactance with fuzzy logic controller in based of state-space examinations. Besides, correspondence less precise reactive power sharing is accomplished in view of inversed voltage droop control include (V–Q droop control) and normal ac bus voltage estimation.
