Summary Microgrid (MG), a localized modular power system comprising of distribution generations (DGs) and loads, acts as a single controllable unit in relation to grid. It may either operate in standalone mode or grid connected mode. It offers benefits like efficient and sustainable energy supply, reduced carbon emission, deferring extension of power distribution infrastructures, and so on. However, integration of DGs having different characteristics results in various operational challenges in a MG network. One of which is power quality (PQ) issue. Hence, in this article, impact of PQ issues in an adopted standalone MG system (comprising of solar, wind and fuel cell based DGs) is investigated in the presence of shunt active power filter (SAPF). The realization of SAPF is carried out using conventional synchronous reference frame (SRF) and modified SRF (MSRF) techniques for reference current generation, proportional integral (PI) controller, and fuzzy logic controller (FLC) for DC‐link capacitor voltage regulation and a basic hysteresis band current controller technique for generation of switching pulse for the inverter. The simulation model of conventional SRF/MSRF techniques and the proposed FLC approach based SAPF is developed under MATLAB/SIMULINKR environment both at ideal and nonideal source condition considering inductive and capacitive load. The results obtained using proposed MSRF technique and FLC approach owing to different load scenarios is compared to that of conventional SRF and MSRF technique with PI controller. The comparative results obtained validate the superiority of proposed technique over other related to harmonics elimination and DC‐link capacitor voltage regulation.

Summary This paper presents design and hardware implementation of single‐phase interleaved inverter as shunt active power filter (SAPF) to mitigate shoot‐through phenomena and power quality problems like current harmonics and reactive power compensation. Shoot‐through phenomena are 1 of the failure mode in conventional voltage source inverter (VSI) which may damage power switches. This also introduces ringing effect and temperature rise and affects the reliability and efficiency of the system. However, external dead band circuits are used to eliminate these problems, but they reduce the harmonic compensation level. Further, the multitudinal sliding mode controller (MSMC) is proposed for stabilizing the DC‐link voltage under steady‐state and transient condition of the load. This has shown an excellent tracking capability with reduced DC‐link voltage ripples compared to the conventional sliding mode and PI controllers. DC‐link energy balance theorem is used for reference current generation. The proposed topology has been modeled using MATLAB®/Simulink environment and tested under the steady and transient condition of the load in different supply voltage conditions. A laboratory prototype has been designed and developed using dSPACE 1104 controller to validate the simulation results. The test results show the viability of the control algorithm and performance of the proposed interleaved inverter in the power quality applications.

“…It consists of three single-phase H-bridge inverter. The advantage of this topology is that the voltage across in each H-bridge interleaved buck inverter appears the singlephase voltage only and hence the reference DC link voltage needed is reduced by √3 times as compared to 3phase interleaved buck inverter with split capacitor topology [10]. Here, in this proposed topology only one DC-link capacitor voltage is required by the p-q control strategy, out of the three individual phases for reference Where i sa , i sb , i sc and i sn represent the corresponding source phase currents and source neutral current.…”

This paper gives a comprehensive study of the novel 3-phase 4-wire H-bridge interleaved buck active power filter (H-bridge IB-APF) which eliminates current harmonics without shoot-through phenomenon and with no dead time effect. In this topology, three single phase H-bridge interleaved buck inverter is being connected with each particular phase and neutral and can be used for high voltage, medium-to-high power application. The adaptive hysteresis current band controller based p-q control strategy is chosen as it is found quite satisfactory for harmonic compensation with optimized switching frequency. The performance of the H-bridge IB-APF is being verified by MATLAB/Simulink and real time study is being done by OPAL-RT real time simulator. As can be seen, the THD of the source current is well below 5% following to IEEE-519 standard with non-linear un-balanced load current. Further the circuit is able to eliminate the shoot-through current which improves the reliability of the filter.I.
