To address the post support disturbances, a modified control strategy is proposed based on SOP. The smooth transition in the active power reference and the appropriate selection of the shaping parameters limit the fall of frequency during kinetic MK0752 regain. With OSOP, the impact of kinetic energy regain is limited even in regions below rated wind speed, for which energy transfers are slightly negative, i.e., the amount of energy regain is slightly higher than the released energy.
Further, for the comparative evaluation two well-known inertia emulating architectures, Governor-Inertia and SOP, were simulated. The performance is evaluated across eleven different operating points, distributed across the entire operating range of the WT. The comparison shows that the proposed method is quite effective over the entire operating range of the WT. The obtained results show that with the OSOP, it is possible to extract the maximum energy from the SKE reserve while keeping the post support disturbances minimum. The OSOP outperformed all three compared architectures in low and medium wind speed regions. In high wind speed region, its performance was comparable with the others in limiting the initial fall of frequency, though it was most successful in limiting post support disturbance and hence provided overall best performance.
