“…The voltage controllers [41] adjust the inverter output voltage and it locates to the current controller. Proportional-integral (PI) controller, two degrees of freedom (2DOF) controller, resonant controller, hierarchical control, and repetitive controller are the several controllers used in the voltage controller design.…”

Abstract-Due to the global demand for energy saving and reduction of greenhouse gas emissions, utilization of renewable energy sources have increased in electricity networks. The negative aspects of this technology are very complex and not well known which affect reliability and robustness of the grids. Microgrids based on renewable energy sources have gained significant popularity, due to the major benefits it has to offer for solving the increasing energy demand. Harmonic distortion in microgrids caused by the non-linear loads is an essential topic of study necessary for the better understanding of power quality impacts in microgrids. The various control techniques utilized to curtail the power quality impacts on micro grids are reviewed in this paper. Also, Optimization based control techniques utilized for power quality improvement in microgrids is discussed in this review.

The switching control schemesincluding sinusoidal pulsewidth modulation (SPWM) and space vector modulation (SVM) are very important for the efficiency and accuracyof the voltage source inverter (VSI). Therefore, this paper presents a performance evaluation of a two-level VSI for the photovoltaic (PV) system based on adopted switching controllers namely, SPWM and SVM switching methods. The evaluation procedure and accuracy are demonstrated and investigated using simulations conducted for a 1.5 kW inverter in a MATLAB/Simulink environment. Two types of loads are utilized to assess the performance of the VSI which are resistive (R) load and resistive and inductive (RL) load. Total harmonic distortion (THD) is used for the comparison of the SPWM and the SVM. Results show that the SVM performs better compared with the SPWM in terms of THD rate. The THDs for SVM based system are found to be 0.02% and 0.08% for the R and RL, respectively; whereas the THDsfor SPWM controller are found to be 0.43% and 0.51% for the R and RL, respectively. Furthermore, mean square error (MSE) is also consideredas a statistical indicator. The MSE indicates that the SVM switching controller technique have superior outcomes compared with the SPWM switching controller technique and thus increases the efficiency of the whole system.

“…These voltages ( , , and ) are then scaled and transformed into a d-q reference frame to simplify the calculations for controlling the three-phase inverter [23,24]. The two DC quantities, namely, and , can be obtained by applying Park's transformation, as shown in Equation (4). This transformation employs a 50 Hz synchronization signal from a phase-locked loop block: To apply the control algorithm in the inverter system, the three-phase output voltages in the synchronous reference frame must be sensed at the load terminals through the appropriate voltage sensors.…”

Photovoltaic (PV) inverters essentially convert DC quantities, such as voltage and current, to AC quantities whose magnitude and frequency are controlled to obtain the desired output. Thus, the performance of an inverter depends on its controller. Therefore, an optimum fuzzy logic controller (FLC) design technique for PV inverters using a lightning search algorithm (LSA) is presented in this study. In a conventional FLC, the procedure for obtaining membership functions (MFs) is usually implemented using trial and error, which does not lead to satisfactory solutions in many cases. Therefore, this study presents a technique for obtaining MFs that avoids the exhaustive traditional trial-and-error procedure. This technique is implemented during the inverter design phase by generating adaptive MFs based on the evaluation results of the objective function formulated with LSA. The mean squared error (MSE) of the inverter output voltage is used as an objective function in this study. LSA optimizes the MFs such that the inverter provides the lowest MSE for the output voltage, and the performance of the PV inverter output is improved in terms of amplitude and frequency. First, the design procedure and accuracy of the optimum FLC are illustrated and investigated through simulations conducted in a MATLAB environment. The LSA-based FLC (LSA-FL) are compared with differential search algorithm (DSA)-based FLC (DSA-FL) and particle swarm optimization (PSO)-based FLC (PSO-FL). Finally, the robustness of the LSA-FL is further investigated with a hardware that is operated via an eZdsp F28335 control board. Simulation and experimental results show that the proposed controller can successfully obtain the desired output when different loads are connected to the system. The inverter also has a reasonably low steady-state error and fast response to reference variation.
