“…The dc side of the converter is connected to the battery module while the ac side is connected to the grid. In order to simplify the control of the three-phase converter as well as to achieve different charging strategies, the direct-quadrature (d-q) transformation is a commonly adopted method to control the three-phase converter [35]. Besides, a voltage modulated direct power control was proposed in [36]- [37].…”

The objective of this paper is to propose bidirectional charging/discharging strategies for three-phase grid-tied converters. The bidirectional power flow control feature of the converter is able to realize both charging and discharging capability. Besides, in order to achieve high charging efficiency as well as extend the life of the battery, five charging strategies are adopted and developed: 1) the constant current (CC) charging, 2) the pulse-ripple-current (PRC) charging, 3) the sinusoidal-ripple-current (SRC) charging, 4) the bidirectional pulse-ripple-current (BPRC) charging and 5) the bidirectional sinusoidalripple-current (BSRC) charging. The direct quadrature (d-q) transformation is utilized for the converter to realize different charging methods. These methods can be achieved by the digital signal processor (DSP) without adding extra circuit components. In addition, the charging power differences between each strategy are considered and analyzed in this paper. Finally, both simulation and experimental results obtained from a 5-kW prototype circuit verify the performance and feasibility of the proposed bidirectional charger. INDEX TERMS Three-phase grid-tied converter, bidirectional chargers, energy storage system.

“…However, the coupling of the frequency control and the dc-link voltage regulation in these control schemes might have a negative impact on the converter stability because the dc-link voltage of the BTB converter is oscillated by the disturbance in each MG system. Several control strategies of the DC-link voltage have been proposed for the BTB converters to improve the stability of the MMG system as well as the stability of the BTB converter [27][28][29]. The interface between multiple MGs based on the BTB converters has been discussed in [7,8,19] to enhance system stability since each MG can participate in the voltage and frequency regulation.…”

“…Several frequency control strategies have been presented in previous works. However, these previous works mainly focused on the regulation of single frequency in the MMG system or design of the frequency management systems with complex algorithms like in [16,17,29,30]. The contribution of this study is to propose a multi-frequency control strategy in the MMG system.…”

“…The contribution of this study is to propose a multi-frequency control strategy in the MMG system. Compared to the frequency management systems in [16,17,29,30], the proposed multi-frequency control strategy is a simpler approach for regulating multiple frequencies in the MMG system. The proposed control strategy does not require any communication system, thus making it easy to extend the MMG system with the proposed multi-frequency control strategy.…”

Multi-Frequency Control in a Stand-Alone Multi-Microgrid System Using a Back-To-Back Converter

Abstract:A stand-alone multi-microgrid (MMG) system can be formed by connecting multiple stand-alone microgrids (MGs). In the stand-alone MMG system where the frequencies of each MG system are different, a back-to-back (BTB) converter can be used for interconnecting the adjacent MG system. The frequency control performance of the MMG system can be improved by designing the suitable controller of the BTB converter. This study proposes a multi-frequency control in the BTB converter to improve the performance of frequency regulation in the MMG system. Autonomous power sharing between each MG system is achieved by using the proposed multi-frequency control. The stand-alone MMG system where two stand-alone MG systems with different nominal frequencies are interconnected using the BTB converter is simulated in this study to show the feasibility of the proposed multi-frequency controller. Each stand-alone MG system consists of an inverter-based distributed generator (DG) that uses a grid-forming converter with a conventional frequency droop controller. The inverter-based DG is responsible for the primary frequency control in each MG system. To show the effectiveness of the proposed multi-frequency control, a comparison study of the multi-frequency control and the single frequency control is presented in this study. Simulation results show that the system stability can be improved by using the proposed multi-frequency controller.
