In a power plant such as micro-hydropower (MHP), an induction generator (IG) is usually employed to produce electrical power. Therefore, an inverter is needed to deliver it with high efficiency. Z-source inverter (ZSI) has been introduced as a topology with many advantages over conventional inverters. This research aims to investigate the performance of ZSI based simple boost control (SBC) in laboratory-scale MHP systems using a rewinding induction generator. This research has been conducted both from simulations and experiments. Based on the result, the waveform characteristic and value of ZSI are close to the desired design. A shoot-through duty ratio of 17% can reach 60 Vrms output voltage, and this condition has a conversion ratio of about 2.05 times. Also, SBC can significantly reduce the Total Harmonic Distortion (THD). ZSI efficiency has a value of 84.78% at 50% of rating load 100 W and an average value of 80%. Compared to the previous study, the proposed design has more economical with the same component for the higher rating power. Moreover, it has a smoother and entire output waveform of the voltage.

“…By injecting correct three-phase voltages in series with the line voltage, this device keeps the load voltage constant [1]. The DVR usually consists of an injection transformer, a harmonic filter, a voltage source converter (VSC), and a control block [2][3]. The energy for compensating the voltage sag can be achieved by using a parallel transformer or a separate source, where selfrecovery management and fast response will be the most important tasks of the control system [4].…”

Dynamic voltage restorer (DVR) is a protecting device for sensitive loads which compensates grid voltage fluctuations. Although using fault current limiting devices (FCL) is a method of protecting loads and electrical networks against short circuits. In recent years, some methods have been proposed to combine these two devices to reduce the cost of converters and use the benefits of each device simultaneously. A new topology and control method to combine a DVR and an FCL is presented in this paper, which with just adding a switch to the conventional DVR, the FCL performance will be available for the network. The FCL-DVR has been developed to provide excellent dynamic performance and faster response time to network failures while maintaining appropriate reliability and a low converter cost. The performance ability of the proposed device is investigated by simulation results.

“…In four-wire systems, by means of a neutral transformer can provide the path of zero sequence current due to voltage and current imbalance and there upon, reduce the current passing through neutral in three-phase four-wire systems [5], [6]. On the other hand, many solutions have been proposed to overcome the other existing challenges and power quality problems in the power industry that among them custom power devices such as dynamic voltage restorer (DVR) and D-STATCOM have an effective role in power quality improvement in the distribution systems [7][8][9][10][11]. One of these devices is D-STATCOM that has been designed based on working principles of voltage source convertor or current source convertor and by injecting current into the system, compensates harmonics due to the nonlinear loads and also allows the control of reactive power, improvement of load imbalance and power factor correction and has the ability to further compensation and very fast response time in comparison with the Static Var Compensator [12][13][14][15][16][17].…”

Distribution Static Synchronous Compensator (D-STATCOM) is a shunt compensator in the distribution systems that one of the most important tasks is to improve the imbalance, reduce and eliminate the nonlinear loads harmonics. Distributed generation resources such as photovoltaic (PV) array can be used as the DC input of D-STATCOM. In this paper, PV array and DC/DC boost convertor are used to stabilize the DC link voltage of D-STATCOM. The main advantage of theproposed method is that for all time provides continuous compensation. Another power quality issues are neutral current in four-wire systems that are created due to the harmonics and system imbalance.Zig-Zag transformer is one of the ways for compensating neutral current and providing isolation between the convertor and flow of the fundamental zero sequence component which contains harmonic neutral current. Role and performance of the distribution shunt compensator in the improvement of power quality indices depends on the performance of its control system. In this paper, the control scheme of synchronous reference frame theory based on fuzzy controller is used for D-STATCOM based on PV and Zig-Zag transformer. Performance and behaviour of the proposed system examined using Matlab/Simulink software and the results will be presented.
