This paper deals with the implementation of a voltage and frequency controller (VFC) for an isolated asynchronous generator (IAG)-based stand-alone wind energy conversion system (SWECS) with a battery energy storage system (BESS) feeding three-phase four-wire loads. The control algorithm for VFC is based on a low-pass filter (LPF) for estimation of reference source currents. The VFC is realized using...

This paper presents a novel plug-in electric vehicle (PEV) model in a voltage controlled bus formulation, suitable to carry out efficient power flow studies of large vehicular fleets. The PEV model comprises a voltage source converter (VSC) and it is different from the family of PEV models based on a PQ bus with unity power factor concept. While active power is regulated at the storage device according...

In this paper, an autonomous wind energy conversion system (WECS) is proposed using a permanent magnet synchronous generator (PMSG). The voltage and frequency (VF) of the stand alone WECS is controlled using a voltage source converter (VSC) with a battery energy storage system (BESS) at its dc link.

In this paper a local generation system (LGS) based on an induction generator (IG) is presented. The IG supplies the active power to the system with the support of a voltage source converter (VSC) for power conditioning. With the LGS connected to the grid through coupling inductors the deficit or the excess of power production of the IG is imported or exported to the grid at unity power factor. In...
