Summary Due to the increasing development of distribution networks, the need to use clean energy resources, and the existence of different single‐phase and three‐phase consumers, the maximum use of both single‐phase and three‐phase distributed generation (DG) units has become crucial. However, the presence of DG units in microgrids (MGs) requires efficient control strategies, for power control and voltage regulation, to achieve a rapid and proper dynamic response with respect to external disturbances and uncertainties. In this paper, in order to improve the dynamic and steady‐state performance of an unbalanced multibus microgrid including inverter‐based single‐phase DGs, a robust control strategy is proposed for controlling the active and reactive power of DGs. The proposed control scheme is composed of a current controller based on an adaptive sliding mode control method in a virtual synchronous dq reference frame, to control the single‐phase inverter output current, and a PI controller to regulate the voltage magnitude of the generation buses connected to DGs. In the proposed control structure, each single‐phase inverter is controlled as a virtual balanced three‐phase inverter, based on the dynamic phasor concept that makes decoupled control of the active and reactive powers of single‐phase inverters possible. In order to evaluate the validity and effectiveness of the presented control structure, a multibus single‐phase MG containing several inverter‐based single‐phase DG units has been simulated in MATLAB software environment, and the performance of the proposed control scheme has been investigated for various scenarios of parametric uncertainties and external disturbances.

“…The precise control of the duty cycle with respect to various atmospheric conditions is obtained in [5]. A peak current controller strategy is used to generate the gate pulses of semiconductor switches which control both active and reactive powers [6][7][8]. PV systems in the future should perform a number of functions like reactive power control, Maximum Power Point Tracking (MPPT), islanding detection, power quality improvement and Fault Ride-Through (FRT) capability [9][10][11].…”

The current grid standards for the single-phase residential PV system expect it to operate at Maximum Power Point Tracking (MPPT) mode under normal operating conditions and to maintain the voltage profile whenever a grid fault occurs. The proposed system supplies power to the load under stable conditions and the PV system works in MPPT mode. When the fault occurs at the Point of Common Coupling (PCC) and the voltage is reduced, the proposed controller maintains the voltage profile by injecting the current fed by the current controller at the PCC. The controller shifts from MPPT to the faulty mode and maintains voltage as per grid requirements. During islanding conditions, the PV system successfully caters to the requirements of the load by shifting the control from MPPT to islanding mode. When the PV system is in operation the power quality is enhanced

“…Photovoltaic (PV) can be considered the most promising type of RES where it has a flexible and modular structure in which it can be integrated to the grid by utilities, investors, and even final consumers [1]- [3]. A unique feature of this RES type is the watt-var control functions of its inverter, thereby providing local control options [4], [5]. However, this further option is accomplished on the expensive of excessive curtailed power in high penetrated PV distribution systems.…”
