“…Therefore, the power quality improvement is a significant issue in GTT along with extracting maximum available PV power [16]. The literature [17][18][19][20][21][22][23][24] lists a broad range of methods of identification of harmonic components. The harmonics methods of detection are mainly used in the load current to isolate the fundamental component and harmonics.…”

“…The disadvantage of the above-mentioned adaptive techniques is their noticeable inability to maintain acceptable performance in the presence of DC-offset as mentioned in [24]. In the context of treating this disadvantage, the proposed SFT-PLL is introduced to extract the fundamental load current component.…”

This paper introduces a multifunction interactive PV system that has the ability to feed a nonlinear local load in either grid-tied topology (GTT) or off-grid topology (OGT) and transits between the two topologies are seamless. The interactive PV system utilizes a sliding Fourier transform-based phaselocked loop (SFT-PLL) as an adaptive and robust control technique for extracting the fundamental load current. Further, the SFT-PLL is also used to synchronize the inverter output voltage with the grid during the GTT. The proposed synchronization technique has a superior immunity to the weak grid problems. The SFT-PLL based control technique has a very good ability to mitigate the nonlinear load harmonics and to deliver active current to the grid with a unity power factor. Moreover, the proposed control technique is able to keep a balanced grid current when the connected load is unbalanced whether the PV source is available or not. The DC-link voltage is controlled by the controller of the voltage source inverter (VSI) during GTT. During the OGT, the AC load voltage is regulated by the VSI controller while the DC-link voltage is regulated by the boost converter controller to satisfy the power requirements of the connected load. The simulation and experimental results show the effectiveness of the proposed control technique in feeding a balanced current with THD adheres to the IEEE-519 standard at different operating conditions. The performance of the proposed method is compared with recently published adaptive filtering techniques to show its effectiveness especially when the load current has a DC-offset.

“…Battery Energy Storage Systems (BESS) are a more viable option compared to other energy storage systems due to their technical as well as economical merits. A number of topologies and control schemes for hybrid systems have been proposed in the literature [1][2][3][4][5][6][7][8][9][10]. Among them, Omar [1] presented a performance analysis of a grid-connected PV-wind hybrid power system during variations of environmental as well as load conditions.…”

Renewable Energy Sources (RES) such as solar photovoltaic (PV) and wind-based generation cannot meet dynamic load demand all the time because of their intermittent nature. Battery Energy Storage System (BESS) is integrated with RES to meet dynamic load demands. Proper power management is needed for the efficient and reliable performance of the system. This paper presents power management of PV-Wind- Battery hybrid system for both grid-connected and islanded modes of operation as well. The power balance is maintained by a power management system (PMS) under different environmental conditions and load conditions, and modes of operation. The control method for state-of-charge (SOC) and battery charge/discharge is applied to ensure efficient performance and safe operation of BESS. Different cases, such as surplus/deficit power available from RES with respect to load demand and battery capacity, have been considered and carried out to verify the performance of PMS using the MATLAB/Simulink platform.

“…As a result, in addition to enhancing the stability robustness of VSIs, a limited bandwidth PLL is typically used, compromising the system's dynamic performance greatly. To circumvent the PLL system's limitations, some studies [23][24][25] proposed frequency locked loop (FLL)-based synchronization solution for the MG's VSI [23][24][25]. Power control approach based on PLL-less CCT is introduced in [26] for grid-tied hybrid MG's VSI.…”
