“…(3) Where (4) The characteristic polynomial of the state matrix is given as (5) By introducing damping control, the attenuation coefficient of DCpower grid can be obtained using (6) According to (6), the variation in attenuation coefficient can be calculated as follows: (7) If Δα>0, the additional state-feedback loop can cause the eigenvalues of DC-power grid to shift to the left, enhancing the DC voltage damping. Therefore, the feedback coefficients kdu and kdi can be satisfied as follows: (8) The variation scope of feedback coefficients kdi and kdu can be limited using (8), ensuring that the proposed control loop always produced positive damping. In the proposed control system, state variables IB and Udc are used to provide the feedback signals, both of which are then added to the output duty cycle of droop control.…”

DC microgrid contains a large number of tightly regulated closed-loop converters, which performance for the constant power loads and may cause stability problem of bus voltage when used as a load since they trend to draw constant power. In order to improve the stability of DC microgrid, this paper proposes a method for stabilization the DC microgrid based on the state feedback. e. In this study, the small disturbance linearised state equation of a DC-power grid with constant power load is derived to estimate the damping characteristics of DC voltage. To enhance the transient voltage stability, a novel DC- voltage damping control method is proposed, where both DC voltage and DC current are used as state feedback variables.
