“…However, PI+R increases the computational burden because one resonant action is needed to reject each one of the unwanted harmonic components. PI control with repetitive action (PI+RC) is a nonselective algorithm that can reject all harmonic perturbation components with one controller [4,23]. Nevertheless, PI+RC performance is degraded with grid frequency variations.…”

Grid background and dead-time harmonic perturbations pose challenges in maintaining power quality and stability in the grid integration of renewable energy conversion systems. Therefore, a super-twisting algorithm with the ability to reject harmonic perturbations on three-phase grid-tied inverters is proposed. The algorithm design is related to dead-time and grid background harmonics so that robust performance is achieved under these perturbations. To highlight the advantages of the proposed algorithm, it is compared against proportional-integral (PI) control in several dead-time and grid background harmonic sweeps. The maximum inverter current distortion obtained with PI control in simulation is 15.53%. However, by using the proposed algorithm instead, the maximum current distortion is reduced to 1.8%. Dead-time is experimentally swept by using a permanent magnet motor as a harmonic-free grid. Experimental results of grid background harmonics are obtained by injecting reactive energy into a grid with 2.19% voltage distortion. When PI control is used in the experimental setup, the maximum inverter current distortion obtained is 11.4%. However, with the proposed algorithm, the maximum current distortion is reduced to 1.5%, which complies with the standard IEEE 1547-2018.

“…If the detected harmonic component is not accurate, the subsequent control will be meaningless. Thus, instantaneous reactive power harmonic current detection mode and current hysteresis control mode are used [19]. Improved APF is used to filter out most of the harmonics, while PF is used to filter out other small portions.…”

The growing number of accessed energy-efficient frequency conversion air conditioners is likely to generate a large number of harmonics on the power grid. The following shortage in the reactive power of peak load may trigger voltage collapse. Hence, this conflicts with people’s expectations for a cozy environment. Concerning the problems mentioned above, an active management scheme is put forward to balance the electricity use and the normal operation of air conditioning systems. To be specific, first, schemes to suppress the low voltage ride through (LVRT) and harmonic are designed. Second, to deaden the adverse effects caused by nonlinear group load running on the grid and prevent the unexpected accidents engendered from grid malfunction, the dynamic sensing information obtained by an online monitor is analyzed, which can be seen as an actively supervised mechanism. The combined application of active and passive filtering technology is studied as well. Third, the new energy storage is accessed reliably to cope with peak-cutting or grid breaking emergencies, and the fuzzy control algorithm is researched. Finally, system feasibility is verified by functional modules co-operation simulation, and active management target is achieved under scientific and reasonable state-of-charge (SOC) management strategy.

“…Among them, the problem of harmonic pollution is the most serious, which has caused a serious decline in power quality of the power grid [1]- [3]. The APF with good compensation characteristics, strong suppression capability and fast dynamic response has become the main method of harmonic control [4]- [6]. Due to the increase in the capacity of switching devices, the APF capacity can meet the requirements of low voltage occasions.…”

In order to reduce the capacity of the active power filter (APF), improve its dynamic tracking speed and anti-disturbance ability of harmonic currents, so as to better solve the problem of harmonic pollution in the medium and high voltage distribution network, this article is suitable for medium and high voltage distribution networks. The three-phase three-wire injection hybrid active power filter (IHAPF) of high voltage distribution network is the research object, and a fuzzy linear active disturbance rejection controller (Fuzzy-LADRC) suitable for IHAPF voltage outer loop control is proposed. The controller is composed of a fuzzy proportional controller, a linear extended state observer (LESO), and a total disturbance compensation link. The introduction of fuzzy logic control solves the difficult problem of controller parameter tuning, and uses Lyapunov stability definition to prove the stability of the system. Finally, the control performance of IHAPF under the control of Fuzzy-LADRC is simulated and verified by MATLAB&SIMULINK simulation platform, and compared with the traditional PI controller. The results show that the Fuzzy-LADRC controller is better than the traditional PI controller and has good tracking and anti-disturbance capabilities.INDEX TERMS injection hybrid active power filter(IHAPF); linear active disturbance rejection controller(LADRC); fuzzy control; voltage outer loop; stability; anti-disturbance characteristics
