The control of grid‐connected inverters is recently executed with digital microprocessors due to the advances in digital signal processing technology. However, the digital realisation has a drawback of the phase lag induced by the time‐delay. This phase lag challenges the stability and robustness of the controller of the inverters. In view of the challenge, this paper presents a comprehensive review of time‐delay compensation techniques employed in both model‐free (MF), and model‐based (MB) controls of an inverter in grid connection. MF techniques mainly use proportional‐integral, and proportional resonance controllers with some techniques to reduce time‐delay. Meanwhile, for MB, this paper discusses the commonly used control techniques, which are the Smith predictor, modified Smith predictor, deadbeat controller and model predictive controller. Several related techniques from the literature that have been adopted to mitigate the delays are tabulated comprehensively, and critical issues regarding the MF and MB techniques are also discussed. Finally, this paper presents a hypothesis on which technique is superior at present and suggests a hybrid technique from the MF and MB techniques to give readers a direction for further research.

Nowadays, more research projects have described a converter that is widely used at the distributed generation (DG) level in order to increase the amount of electrical power generation. The converter is known as an inverter when only one DG source is used or as a multi-inverter when several DGs are used. Here, the application of a multilevel inverter with a C2000 microcontroller (Texas Instruments (TI) TMS320F28335 microcontroller), which can be implemented with a current feedback loop, is investigated. This microcontroller acts as a communication interface between MATLAB SIMULINK and the multilevel inverter. Meanwhile, the current control model is modeled in MATLAB for designing the control strategy. It is where the multilevel inverter switches are triggered by using pulse-width modulation (PWM) signals generated by the microcontroller output. At the same time, the proportional integral derivative (PID) current control is used in order to allow the load current to follow the reference current. Based on the results, it can be summarized that the multilevel inverter is a very useful device for the next DG sources when it is combined with current control for load current distribution. From this investigation, it can be seen that in the future DGs could be connected to a multilevel inverter structure, where it will reduce the dependency on filter design and have a more sinusoidal output to the load for different DG power ratings.

This paper is written to give a complete comprehensive analysis on sensorless Field-Oriented Control (FOC) in electric vehicle motor application. Sensorless control has opened a wide discussion in terms of its low cost and less complexity for crucial applications such as in electric vehicle, where rotor speed can be estimated by measuring the quantities of stator voltage and current at the terminal of the motor. Therefore, this paper provides a comprehensive review of the control methods for sensorless motor in order to increase motor efficiency. This review is based on vector control, which is the main focus in this paper, and on how it can be used more effectively in a wide speed range. Several tabulated tables are presented in order to give a fair comparison in determining the advantages of sensorless application of FOC in the estimation method for flux and speed controls. These tables show the effectiveness of each vector control in order to achieve the FOC. Lastly, the authors estimate the error, torque ripple and efficiency of the motor in order to allow readers to choose a suitable sensorless control for an effective method to increase the efficiency of an electric vehicle.

This project describes the investigation on the Proportional Resonant (PR) control and its performance for a 7-level multilevel inverter using only 5 switches of devices in the single-phase inverter. The performance of the PR control is measured based on the ability of the controller to reduce the harmonic distortion in the inverter output system when connected to a non-linear load. This project is divided into two parts: firstly by using the MATLAB simulation, and then testing the hardware implementation. The results of the multilevel simulation in MATLAB/Simulink show that the implementation of the PR control in the inverter system can reduce the total harmonic distortion caused by the non-linear load; meanwhile, the hardware results show that the PR controller system is applicable and functioning well for generating a 7-step level using TI microcontroller based on current PR control strategy system.

This paper explains an improved capacitor voltage control (i-CVC) by combining with maximum power point tracking (MPPT) algorithm as a control strategy for a single-phase Z-source inverter (ZSI) using photovoltaic (PV) source. The existing CVC based-MPPT control algorithm has a net shoot-through interval which should be inserted in the switching waveforms of the inverter to produce maximum power at the Z-network of the PV. However, this net shoot-through period is formed by an additional shoot-through period which has drawbacks as it boosts the capacitor voltage to a greater extent beyond the allowable voltage boundary of the capacitor. İn other words, the PV will boost the voltage more than the desired level as per required by reference capacitor voltage of the Z-network. Due to this problem, an improved capacitor voltage control (i-CVC) with general Perturb and Observe (P&O) based on ΔT0’ configuration of the changes shoot-through duty cycle to maintain the DC-link of the ZSI is introduced and been tested in simulation case with a resistive load. At the end, this modification able to assist the MPPT output power by increasing the overall system effectiveness of power generation by the PV.

This paper performs a comprehensive survey on power flow control scheme and is applied to a single-phase hybrid energy system. The survey is made based on the performance of the system during operation in islanding and grid-tied modes. It covers the coordination of control strategies and the stability and the efficiency of the controller techniques among the hybrid systems. At the same time, the system must be able to stabilize the voltage level as well as to control the flexibility of power flows. Therefore, this review is based on droop control concept and has been coordinated with adaptive and robust control mechanisms. The importance of these controllers is to see the adaptability to various conditions practically, such as disconnection of transition of those modes whenever there are dynamic changes to the hybrid system. For this reason, the droop control scheme must able to fulfil the performance requirements to achieve faster and smoother transition associated with islanded and grid configurations. Moreover, it also should provide an effective system performance in terms of setting up the power control strategy to manage the power flows among the inverters connected to local loads. As a conclusion, this paper has tabulated several important tables on the variety of droop control techniques that are suitable for different case systems for the hybrid-islanded-grid connection. As an ultimate goal, it is also to provide information covered from the system configuration to choose the right controller that can balance the power in the system and generate a continuous load voltage waveform during transient.

In this project, the development of MPPT based on Z-Source single phase inverter using a Raspberry Pi with voltage control is proposed in order to increase and boost the inverter output to be greater than the input solar power. The main features of this system is the ability to control the Raspberry Pi gate signal switching inverter while controlling the duty cycle of the pulse width modulation based on MPPT algorithm. In order to ensure the output voltage can be as maintain as desired, MPPT algorithm will make changes to the duty cycle by tracking to maximum power point (MPPT) of the PV cell, while Proportional (P) controller is used in this system as a controller which functions to make sure the inverter output is equal to the target reference value. The effectiveness of this control strategy is implemented in MATLAB Simulink and verified by experimental results using PI reference 5Vpk, 10Vpk and 15Vpk. It is proved that, the voltage can be corrected and stabilized using these control methods.

In grid connected system, unity power factor current injection into the grid is vital. This can be achieved by choosing the right inverter topology, passive filter components, current controllers, and PWM switching scheme. This paper compares the output current harmonics profile between when using the conventional proportional resonant (PR) current controller and when using the modified PR current controller. By applying the latter technique, via experimental validation using TMS320F2812, the THD of the injected grid current in a parallel connected inverters system is improved.

In this paper, a fast-synchronization between grid and inverter based on virtual synchronous converter (VSCon) technique is achieved in single-phase inverter. Consequently, this technique is designed and simulated in Matlab/Simulink platform to perceive the significances during variation of grid load parameters. The VSCon is implemented for inverter output control that has a behavior of grid voltage and frequency synchronization using droop control mechanism. This technique has been tested in inverter-microgrid connection with several loads connected. In case of 0.1 Hz grid frequency changes in grid test, it takes nearly 230ms to synchronize between inverter and grid frequency even with loads connected to the test system. Hence, this proposed technique can be implemented in microgrids with several distributed generation sources without using the PLL for fast synchronization between grid-inverters.

This paper explains the control techniques that have been applied to the 3-phase inverter for a grid connected system. The H ∞ current control strategy with the Voltage Oriented Controller (VOC) with power control have been used together, in order to respond to the power required by the grid. The VOC control consists of a real and reactive power control with feedforward dc-voltage control. A simple synchronization method has been used in order to allow the power flow from the inverter to the grid can be achieved. Finally, the simulation results show, the proposed control strategies are able to control the power flow based to the reference power where the proposed controller generates around 5% of low power error signal.
