Summary The aim of the paper is to provide seamless transition between the grid connected to an islanded mode and vice versa by switching the control of the load connected VSC (LCVSC) ensuring uninterruptable power supply. In the grid connected mode, a TOQSG (third‐order quadrature signal Generator) based method is applied for power quality improvement at the grid. During synchronization, the LCVSC adapts the phase and frequency of the grid voltage for seamless transition. The paper presents a smart microgrid, which manages the mode of operations and generation of reference signals for the smooth operation. The proposed approach is validated through test results. The grid current and CCP voltage distortion are as per the IEEE‐519 and the IEEE‐1547 standards.

“…The second mode aims to enhance the HS power quality by reducing the fluctuations of the output power for different weather conditions. This objective aims to smooth the total power produced by the hybrid system in a way that is different from unlike other works which deal the subject of energy quality for the hybrid systems through other techniques and according to other concepts, such as: the technique that applies the improved control strategy for power quality enhancement in standalone systems based on four-leg voltage source inverters (presented in [13]), the technique that aims to achieve the power quality improvement of single phase weak grid interfaced hybrid solar PV and wind system using double fundamental signal extracter-based control (presented in [14]), the technique aims to improve the voltage of remote connection using wind-solar farms equipped with new voltage control strategy based on virtual impedance monitoring (presented in [15]) and the technique which aims to improve the energy quality using a shunt active power filter (presented in [16]).…”

The Adrar site located in the south of Algeria, presents the most important windy and sunny site in Algeria that can be exploited. In this context for the exploitation of the two complimentary sources of this site (wind and sun) based on the meteorological data, the present paper focuses on the study of a Hybrid System (HS) based on an interconnection between a Wind Energy Conversion System (WECS) and a Photovoltaic System (PVS) which is planted in the DC-link bus of the back-to-back converter feeding the Double Feed Induction Generator (DFIG) rotor of the WECS. The objective of using this proposed coupling topology is to exploit the two available complementary renewable sources in the same time, to enhance the exploitation rate of the un-resized WECS back-to-back converter which remains at low power in the weak wind case or in the synchronism case and to eliminate the PVS inverter. Consequently the overall cost of the HS can be reduced. On the other side, to solve the energy quality problem; a modified MPPT mode control technique is proposed and compared with two other conventional techniques, the first one uses the PVS to offset only the WECS power rapid fluctuations and the second one uses a Battery Storage Unit (BSU) to ensure the produced energy smoothing. This BSU plays also an interesting role to store the surplus of energy when the maximum power level of the WECS converter is reached in case of wind and/or irradiation abundances.

“…To synchronize with the grid, PLL must extract precise data about grid voltage, magnitude, and frequency. Poor performance of the conventional synchronization controller using the synchronous reference frame (SRF) PLL has been demonstrated under power quality problems such as voltage imbalance, disturbances, and the presence of low-order harmonics in the system [13]. The p-q theory was originally employed in a three-phase system.…”

This paper investigates the performance of a single-phase grid-integrated photovoltaic based DSTATCOM by using modified p-q theory control algorithm. Previously, p-q theory controller has been employed for a three-phase DSTATCOM system. Thus, this paper employs a modified p-q theory control algorithm for a single-phase grid-integrated solar PV (GCPV) based DSTATCOM. Thus, the GCPV system has improved with DSTATCOM capabilities such as harmonic reduction for a single-phase distribution system under varying solar irradiances. The simulation results have been obtained by using MATLAB/SIMULINK software in accordance with IEEE Standard 519:2014, which stated that the THD should be less than 8% for the line current at the Point of Common Coupling (PCC). The performance of the single-phase GCPV based DSTATCOM has been analysed for dynamic and steady-state conditions under varying solar irradiances.
