“…The AI techniques were implemented in a single board of National Instruments based on a field‐programmable gate array (FPGA) Xilinx Spartan‐6 LX45 at 2.5 MHz. Also, the main inverter controller implemented in simulation and experimental tests is a digital controller, where the errors between the sensed currents on the PCC and sinusoidal references stated by the voltage grid are minimised by a single band hysteresis current controller, which is best known for robustness, fast error tracking, good dynamic response, and ease of implementation [34].…”

This study presents an active anti‐islanding technique for distributed power generator systems. The proposed scheme is based on the Sandia voltage shift (SVS) technique, which is characterised by a small non‐detection zone (NDZ) and by an acceptable solution to the trade‐off between the output power quality and the effectiveness of islanding detection. The proposed technique has the advantage to improve the NDZ and to reduce the anti‐islanding detection times. This is due to the exponential‐product modification made in the positive feedback to inject current, thereby making the response faster than SVS. Additionally, a self‐adaptive gain is considered to achieve a low total harmonic distortion at different power levels. Moreover, the proposed scheme has been validated with theoretical and numerical analysis and experimental results. Finally, the behaviour and performance of the proposed technique are compared with other recent techniques.

“…The implemented control structure is presented in Figure 8. PR controllers were used in both axes of the stationary frame (α and β) and implemented through Equations (3)- (8). The synchronization with the grid is performed using the second order generalized integrator phase-locked loop (SOGI-PLL) algorithm, characterized by Equations (16) and (17) with a sampling frequency of 20 kHz.…”

“…The most commonly used controllers with a nonlinear control structure are hysteresis controllers, predictive controllers, and deadbeat controllers [7]. Hysteresis controllers are widely used because of their characteristics: simple implementation, low cost, and fast dynamic response [8,9]. However, these controllers have the disadvantages of introducing harmonics into the current shape.…”

Proportional Resonant Current Control and Output-Filter Design Optimization for Grid-Tied Inverters Using Grey Wolf Optimizer

This paper proposes a new method for the simultaneous determination of the optimal control parameters of proportional resonant controllers and the optimal design of the output filter of a grid-tied three-phase inverter. The proposed method, based on the grey wolf optimization (GWO) algorithm, addresses both optimization problems as a single process to achieve a better system frequency response. It optimizes the unknown parameters by using a fitness function to find the best trade-off between the following fundamental terms: the harmonic attenuation rate; the power loss, through the damping resistor; and the current tracking error in the stationary frame, ensuring the system and grid stability. To validate the proposed optimization methodology, two case studies are considered with different output filter topologies with passive damping methods. The results obtained from the proposed optimization procedure were analyzed and discussed according to the fitness function terms.

Single-phase inverters are widely used in different renewable energy applications. Although the full-bridge inverter istypically used, dual-buck inverters provide an important advantage, since they eliminate the shoot-through problems. However, solutions proposed in the literature require additional inductors, use linear controllersdesigned around an operation point, or cannot be used in grid-connected applications. This paper presents a hysteresis current control of a single-phase dual-buck full-bridge inverter for grid-connected active power injection. Includes the dynamical modelin state variables, as well as analytical conditions to guarantee the evolution of the error dynamics in a set with boundaries defined by the designer. Moreover, the paper provides guidelines for the design of the dead band required for the transitions between the positive and negative semi-cycles (and vice-versa) of the grid voltage. Finally, simulation results validate the main features of the controller as well as the design of the dead band
