This paper presents a dual-stator brushless doubly fed induction generator-based stand-alone wind energy conversion system (DSBDFIG-SA-WECS). With the advantages of compact structure, high reliability, and low cost, the DSBDFIG-SA-WECS shows great potential in wind energy applications. Based on the traditional stator-flux-oriented control (SFOC), an improved direct voltage control (DVC) is proposed...
In recent years, with the promotion and application of photovoltaic (PV) technology, research on grid-connected inverters incorporating with weak grid has become a hot field. In general, the large grid impedance will reduce the gain and bandwidth of the control system and slow down the dynamic response, or even lead to resonance and instability of the whole control system. Especially, when the grid...
