| Summary: | A supercapacitor storage system (SCSS) is used for improving the dynamic performances of
a microgrid (MG) fed by a self-excited induction generator (SEIG), in the case of the direct
start-up of an induction motor (IM) of comparable power. The primary control system contains
a voltage source inverter (VSI) with a dump load (DL), to which the SCSS is added. The
control strategy for the SCSS consists of injecting power into the VSI DC-link when,
because of the overload created by the IM, the DC voltage decreases under the acceptable
limit. Thus, the overall performance of the SEIG-supplied MG is significantly improved.
Simulations and experimental results accomplished on a laboratory-scale MG validate the
effectiveness of the proposed control structure. |
