Power balance control for switched reluctance generator integrated in DC microgrid

This paper presents a power balance control (PBC) scheme for switched reluctance generator (SRG) wind power system integrated with DC microgrid. First, a switched reluctance generator wind power system is, which acts as distributed energy source, is integrated with a 24V utility DC microgrid. With proper convertor design and control characteristic for SRG system, output voltage ripple is minimized, which makes it possible for directly connection. Then proposed PBC is achieved on DSP controller for a 3 phase 12/8 SRG system. With proposed control scheme and control system, SRG can change control target dynamically with signals on DC bus. In the end, both simulations and experiments demonstrated proposed PBC well.
