“…The ratio for four converters' rated capacity is 2: 2: 1: 1 from converter 1 to 4. The nominal voltage for the dc MG is 120 V. According to the standard [14], the upper voltage boundary is set as 122V which is smaller than 120*(1+2%)V, while the lower voltage boundary is set as 118V which is larger than 120*(1-2%)V. The experimental results are shown in Fig. 7-9.…”

A highly flexible and reliable control strategy is proposed to achieve bounded voltage and precise current sharing, which is implemented in a reverse-droop-based dc Micro-Grid. To acquire the fast-dynamic response, the reverse droop control is used to replace the V-I droop control in the primary level. In the secondary level, the containment-based controller is proposed to bound the bus voltages within a reasonable range and keep the necessary voltage deviations for power flow regulation; the consensus-based controller is simultaneous involved to regulate power flow achieving accurate current sharing among converters. Combined the proposed controllers with the electrical part of the dc Micro-Grid, a model is fully developed to analyze the sensitivity of different control coefficients. Experimental results are presented to demonstrate the effectiveness of the proposed method. Keywords-Containment-based distributed control, bounded voltage, current sharing, large signal model, dc microgridI.

The objective of this study was to develop a reducedorder small-signal model of a microgrid system capable of operating in both the grid-tied and the islanded conditions. The nonlinear equations of the proposed system were derived in the dq reference frame and then linearized around stable operating points to construct a small-signal model. The high-order state matrix was then reduced using the singular perturbation technique. The dynamic equations were divided into two groups based on the small-signal model parameters ε. The "slow" states, which dominated the system's dynamics, were preserved, whereas the "fast" states were eliminated.Step responses of the model were compared to the experimental results from a hardware test to assess their accuracy and similarity to the full-order system. The proposed reduced-order model was applied to a modified IEEE-37 bus gridtied microgrid system to evaluate system's dynamic response in grid-tied mode, islanded mode, and transition from grid-tied to islanded mode.

“…The υ max is global value for all converters and it is approximately 5% of the rated voltage [19]. Although the virtual resistances are selected based on the converter ratings of the sources, the droop controller cannot ensure proportional current sharing under the effect of transmission line impedances.…”

“…The main control objective in a MG is to ensure a proper load sharing among the sources. Several control techniques, such as master-slave and feeder flow, have been introduced in the literature to perform a proper power sharing in parallel-connected converter systems [19][20][21][22]. The droop control method has been widely accepted and used to achieve an efficient load sharing among the sources in the MG systems [5-13, 19, 20].…”
