 Abstract: An efficient Fuzzy Logic Controller (FLC) is proposed for maintaining constant voltage and frequency in a Decoupled DC micro grid system. The micro grid is modeled with solar, wind turbine, Fuel cell, battery and loads. Individual fuzzy MPPT (Maximum Power Point Tracking) controllers have proposed for solar, wind and fuel cell to extract maximum power from the sources and also to maintain constant voltage at DC bus. For the bidirectional power flow among the buses in the micro grid with power management strategy, an efficient Fuzzy logic controller is proposed for the bidirectional converter connected between DC and AC buses. The performance indices such as ITAE, ITSE, and settling time, rise time of DC link voltage has determined and it is being compared with the conventional Proportional Integral (PI) controller to endorse the performance of the proposed FLC. The results prove that the FLC has better performance in all aspects and it is more suitable for the power management in micro grid.

Summary In a hybrid AC‐DC microgrid, the interlinking converter (IC) is used for tying AC and DC subgrids as the medium of power transfer between the two subgrids. Within an islanded hybrid microgrid (HMG) power transfer between droop controlled AC and DC subgrids is done through IC to achieve power sharing between the subgrids. Further, in this paper, a modified control strategy for IC is proposed for carrying out active power filtering also. Under non‐linear loading conditions, IC in conjunction with the DC subgrid can be used as an active power filter (APF), to filter the AC side line currents and to maintain a sinusoidal voltage at the AC bus. This type of control of the IC in an islanded HMG is so far not much investigated. In this paper, an HMG is simulated in MATLAB/Simulink for different loading conditions, considering linear and non‐linear loads and various set of simulation studies are presented for validating the effectiveness of the proposed control strategy. The system is also implemented using real‐time digital simulator hardware, and the obtained results are presented to support the efficacy of the proposed control strategy.

“…Among the major issues, power and voltage control plays a significant role in the microgrids since frequency is related to real power control (P-f) and voltage is related to reactive power (Q-V) control. The power management has been done by the active power control [1,2], reactive power control [3,4], AC/DC bus voltage control [5][6][7] , storage control [8][9][10] and control of interlinking converters [11,12]. AC microgrids are employing real power and reactive power droop control, whereas DC microgrids are adopting voltage and current droop control methods [13].…”

A novel Set Point Weighting Iterative Learning Controller (SPW-ILC) has been proposed for voltage stabilization at AC/DC bus, coordinated control among the distributed sources in the modeled hybrid microgrid (HMG) and synchronization of HMG with utility grid. The Aichi Micro grid test system located at Aichi Institute of Technology, Japan has been considered for the simulation studies and modeled in MATLAB/Simulink environment. The Aichi microgrid can be operated in autonomous mode as AC system and DC system. When it is working as DC system, the dc bus voltage is maintained stable by incorporating dedicated fuzzy logic controllers (FLC) for DC-DC converters due to the variable distributed sources. Meanwhile, the bidirectional converter also called as Interlinking Converter (IC) located between ac bus and dc bus controlled by proposed SPW-ILC converts the DC voltage into AC voltage and meets AC loads. In AC system of autonomous mode, the inverters are controlled by proposed controller to meet the ac demands. The grid connected mode of Aichi microgrid system is performed by properly controlling the IC to meet ac and dc loads. The proposed SPW-ILC reduces the voltage deviation and maintains the power balance under variable source and load conditions. The results have been compared with the conventional proportional integral (PI) controller and FLC to validate the performance of the controller. The results show that the proposed SPW-ILC has efficiently control the voltage and maintain the power balance.
