“…The main idea of passivity control is to control the energy in the transmission converter within a reasonable variation range by designing an energy storage function. Therefore, by adjusting the structure of the energy storage function, the good performance of the flexible DC transmission converter can be improved, and the results of the passive controller can be lightweight [6]. Passivity means that the current operation inside and outside the power system is always accompanied by energy consumption.…”

At present, the conventional flexible DC transmission converters mainly track the internal energy through sliding mode control or PI control. Due to the lack of dynamic adjustment of controller parameters, the control effect is poor. For this reason, a passive control technology for flexible DC transmission converters based on an improved ant lion algorithm is proposed. The passive controller is designed by constructing the energy storage function. The ant lion algorithm is used to dynamically solve the optimal parameters of the passive controller, and the control process is optimized by adjusting the transition time and overshoot. In the experiment, the control performance of the designed passive control method is tested. The final results can prove that the proposed method has a fast convergence speed of energy function and an ideal passive control effect when it is used to control the transmission converter.

“…Moreover, the droop strategy may lead to circulating current problems in DC subgrids. To avoid these issues, secondary controllers are added above the primary droop controller in DC subgrids [17]. For the secondary controller, the low bandwidth communication (LBC) channel shares the desired information to mitigate the voltage droop error and establishes a coordinated power flow among the subgrids [18].…”

Multiple DC subgrids in close proximity can be connected to form a DC microgrid. The interconnected DC subgrids enhance reliability and efficient utilization of resources. In this paper, a novel coordinated power management strategy is proposed for interconnected subgrids of a DC microgrid. Each DC subgrid has PV and battery units. The proposed strategy is implemented on interlinking bidirectional converters (IBCs). The strategy considers the state-of-charge (SoC) and charging/discharging current of the batteries for SoC balancing-based power sharing through IBCs. A fuzzy logic controller is implemented to decide the amount of power flow through the IBCs from SoC and the charging/discharging current of battery units. Moreover, with the coordinated strategy, a high SoC battery takes more loads compared to a lower SoC battery. The proposed strategy supports fast charging and fast discharging of batteries depending on the SoC level. In addition, the coordinated strategy can seamlessly transfer the control of IBC from the power regulating mode to the voltage regulating mode without any additional control scheme during an outage of the battery unit. The feasibility of the proposed strategy is validated through simulation in MATLAB/Simulink and OPAL-RT real-time digital simulator.
