We address the topic of a unified controller for maximum power point tracking (MPPT) in distributed hybrid PV and wind energy systems. The power produced by a PV module depends on the solar irradiance and temperature. The power produced by a wind turbine depends on the wind speed. The maximum power controllers adaptively search and maintain operation at the maximum power point for changing irradiance and wind speed conditions, thus maximizing the system output power and consequently minimizing the overall system cost. Various conventional MPPT algorithms have been proposed for ideal conditions, few algorithms were derived to extract true maximum power under abrupt changes in wind speed and partial shading conditions. Very few algorithms have addressed the problem of very fast changes in wind speed and continuously varying shading. Under these dynamically changing conditions, the conventional MPPT controllers can't find the true MPP (global MPP) and are often track to a local one. In this work, results are obtained for a tracking algorithm based on Bayesian information fusion combined with swarm intelligence. Compared to state-of-the-art trackers, the system achieves global maximum power tracking and higher efficiency for hybrid systems with different optimal current, caused by continuously changing wind speed and uneven insolation.

This paper presents an digital dual-mode-structure repetitive control approach for the single-phase shunt active power filter (APF), which aims to enhance the tracking ability and eliminate arbitrary order harmonic. The proposed repetitive control scheme blends the characteristics of both odd-harmonic repetitive control and even-harmonic repetitive control. Moreover, the convergence rate is faster than conventional repetitive controller. Additionally, the parameters have been designed and optimized for the dual-mode structure repetitive control to improve the performance of APF system. Experimental results on a laboratory setup are given to verify the proposed control scheme.

Smart micro-grids offer a new and challenging application environment for modern power electronics. In fact, smart micro-grids are populated by a plethora of distributed energy resources (DERs), which interface with the distribution grid by means of electronic power processors (EPPs). This scenario enables the distributed control of the active and reactive currents flowing in the power lines, with a tremendous potentiality to improve the grid performance in terms of distribution efficiency, power sharing, voltage stabilization, hosting capacity and demand response. This paper presents a simple and powerful approach to cooperative control of distributed EPPs, which only requires narrowband communication among neighbouring units. The proposed scalable and flexible distributed control architecture provides prompt response to power transients and efficient operation of the micro-grid in both grid-connected and islanded conditions.

This paper presents a new Space Vector Pulse Width Modulation (SVPWM) strategy for voltage regulation of a Voltage Source Inverter (VSI) enabling the continuous transition from the linear modulation to the six-step mode. Overmodulation operation is based on a correcting function method modifying properly the amplitude and the phase angle of the VSI output voltage. The evaluation of the method is explored via frequency analysis of the inverter voltage and motor currents in order to be able to evaluate the possible impact of the drive system. Simulation results demonstrate the effectiveness of the proposed SVPWM Overmodulation algorithm applied on sensorless speed control of a salient-pole Synchronous Machine (SM) via Matlab/Simulink utility.

Distributed Generation (DG) based on renewable green energy is expected to grow at an unexpected rate. However increasing penetration of DG to the power grid has issued power quality of power system. Among the power quality problems, the harmonic current may corrupt the power system which is connected to the grid. Accordingly, the performance of DG systems must be improved to meet the grid codes in each country. In this paper, a novel selective harmonic suppression method based on a robust PLL Algorithm is proposed and demonstrated using PSIM. The proposed algorithm is applied over the harmonic current detection of a nonlinear load. Now 10kW prototype active power filter (APF) is set and verification experiment will be conducted with the nonlinear load.

This paper presents a novel digital P-I-D control FPGA for a switching power supply in the higher voltage direct-current (HVDC) power feeding system. At first, digital fast P control buck type converter is presented. Then, the appropriate number of sample point is determined. Then the fast P control is applied to the full bridge converter for HVDC. The acceptable delay time, with realizing superior dynamic response, is half of a switching cycle based on the appropriate number of sample points of buck converter. In the proposed method, the calculation processes of P and I-D controls are parallel. The delay time of P control is less than that of I-D control. The step change against the load will be discussed. It is revealed that the proposed circuit has the superior transient response. Then the proposed digitally controlled phase-shift full bridge dc-dc converter is verified with 800W proto type. The maximum power efficiency is about 92%. Then it is confirmed that proposed digital controlled phase-shift full bridge dc-dc converter achieves superior transient response compared to conventional one.

In this study, implementation of a 10kW three-phase grid-connected inverter system is discussed. The system includes a high voltage dc-link, a two-level inverter and filter inductances. The high voltage dc-link is obtained from AC grid by means of a transformer, a diode rectifier and filter capacitors. The two-level inverter is controlled with SVPWM technique, and L filter is used between the inverter and the AC grid. The system is simulated in MATLAB/Simulink and, appropriate dc-link voltage, filter inductance and switching frequency values are selected. The experimental results are presented from the laboratory prototype which is controlled by dSPACE DS1103 board to demonstrate the power control and harmonic performance. It is observed that at 9 kHz switching frequency, 650V dc-link voltage and 10 kW output power, the total harmonic distortion of the grid current is less than 3.4%, and power factor is higher than 0.99.

A new cross-segmented power supply rail for roadway powered electric vehicles is proposed in this paper for reducing construction cost and EMF. The proposed rail consists of two pairs of power cables, core, bi-directional power switches, a transformer, capacitors, and harness. Each rail is connected through a switch box, which can change the current direction of a pair of power cables. Hence, adding the current of the two pairs of power cables results in the activation mode while nullifying it does the silence mode. A coupling transformer with two capacitors is introduced to compensate the variable line inductance of the rail due to the change of current direction. Therefore, multiple rails can be concurrently activated by selective turning-on and off the power switches using an inverter. In addition, the EMF for the silence mode drastically is reduced if a twisted pair of power cables is used. The proposed cross-segmented power supply rail was implemented for experiments and verified for practical applications.

This work presents a reliability analysis of the power electronic converters for a grid-connected permanent magnet generator-based wind energy conversion system based on the semi conductor power losses. The power converters examined are: the intermediate boost converter (IBC), the intermediate buck-boost converter (IBBC), the back-to-back converter (BBC) and the matrix converter (MC). The aim is to determine which power electronic converter yields the highest mean time between failures (MTBF) and reliability in terms of power losses of the semiconductor devices with a predetermined wind speed. In view of this, a furled wind turbine model developed previously by the author is used to generate power for different wind speeds. Afterwards, a relation between the wind speed, power loss and MTBF is established to evaluate the reliability of the power electronic converters. The power loss model presented in this paper has taken into account the conduction and switching losses of the semiconductor devices within each converter. The analysis reveals that MTBF of an IBC is much higher compared to the other converters considered in this research. The investigation is extended to identify the least reliable component within the converters. It is shown that the inverter has the dominant effect on the system reliability for the converters. This research indicates that IBC with a simple rectifier is a much better option for grid-connected permanent magnet generator based wind energy conversion system.

The single three-phase hybrid power system has the characteristic that the network structure is very complex. Based on signal injection method, a synthesized fault location method aimed at this characteristic is proposed in this paper. The method can fix fault segment with DC signal and fault position with AC signal. In this way, not only avoid the wrong judgment of fault branch because of the distribute capacitance, but also solve the abuse of longtime line patrol. At last, build a single three-phase hybrid power distribution model based on MATLAB to verify the feasibility of this method. The result shows that this method can improve the accuracy and efficiency of fault location.
