“…A bi-directional power flow scheme has been proposed in [17], where the power flow between the AC main grid and DC microgrid is controlled through a DAB converter. In References [18,19], the reactive power control of a DAB converter is assessed. Reference [20] focused on reducing the current stress.…”

“…In Reference [7], the DAB converter average and small-signal models have been validated through both simulations and experimental tests for the four different control modes. The DABs have also been the object of study in [9][10][11][12][13][14][15][16][17][18][19][20]. Even though several control strategies have been explored for the DAB, the most common among practitioners is the simple phase shift modulation technique [17,18] based on conventional PI controllers [20,21].…”

In this article, three evolutionary search algorithms: particle swarm optimization (PSO), simulated annealing (SA) and genetic algorithms (GA), have been employed to determine the optimal parameter values of the fractional-order (FO)-PI controllers implemented in the dual active bridge-based (DAB) DC microgrid. The optimum strategy to obtain the parameters of these FO-PI controllers is still a major challenge for many power systems applications. The FO-PI controllers implemented in the DAB are used to control the DC link voltage to the desired value and limit the current flowing through the converter. Accordingly, the investigated control system has six parameters to be tuned simultaneously; Kp1, Ki1, λ1 for FO-PI voltage controller and Kp2, Ki2, λ2 for FO-PI current controller. Crucially, this tuning optimization process has been developed to enhance the voltage stability of a DC microgrid. By observing the frequency-domain analysis of the closed-loop and the results of the subsequent time-domain simulations, it has been demonstrated that the evolutionary algorithms have provided optimal controller gains, which ensures the voltage stability of the DC microgrid. The main contribution of the article can be considered in the successful application of evolutionary search algorithms to tune the parameters of FO-based dual loop controllers of a DC microgrid scheme whose power conditioner is a DAB topology.

“…It is presented the modeling in the frequency domain of the input DMC normalized current of a lossless DAB, in such a way that the performance characteristic of power factor and DMC normalized harmonic impacts can be observed through this suitable plane. As it is presented a lossless theory, the power factor will represent the notion of efficiency, as the amount of reactive power impacts on both the efficiency [7] and the power density, whereas the first harmonic appearing in the lower limit of the frequency spectrum represent the effort for filtering to comply with regulations. Therefore, both analysis of power factor and DMC first harmonic represent how much the converter in a general way (filter, isolation, cooling, and etc.)…”

This paper investigates the conducted Differential Mode Current (DMC) harmonic magnitudes and the Power Factor (PF) produced by a Dual Active Bridge (DAB) converter operated under single phaseshift modulation. Power factor and the first harmonic are modeled and analyzed though a dimensionless plane of static gain versus output parametrized current. It is shown that voltage and output current ranges have a significant impact on the magnitude of the reactive power and DMC filter needs, which can therefore compromise the performance of the DAB. Especially, the DMC should be considered in the DAB converter design optimization to avoid EMI filter oversizing or non-compliance with respect to EMC standards.
