In a grid-connected photovoltaic system, the quality of energy injected by the photovoltaic system into the grid is directly linked to the topology of the inverter used and to the efficiency of its control technique. This paper addresses this problem for a two-level grid-connected photovoltaic inverter operating under low irradiance conditions. The aim is to reduce the harmonic distortion on the electrical network and therefore improve its power quality. To achieve this goal, a control strategy was set up considering the nonlinearity of the dynamic system, and the high dimension of the system model. Thus, a nonlinear controller designed using the backstepping technique is proposed. The effectiveness of this control strategy was evaluated by simulation in MATLAB/Simulink. Results show that the proposed control technique significantly improves the power quality of the grid-connected photovoltaic system by minimizing the current harmonic distortion rates in low irradiance conditions. The current harmonic distortion rates obtained for solar irradiance of 1000 W/m2, 750 W/m2, 500 W/m2, and 250 W/m2 are 0.48%, 0.78%, 1.22%, and 2.16%, respectively. The power factor is 0.988, and the DC bus voltage is maintained at its reference voltage of 600 V with a very low response time during the transient phases. A comparison of our simulation results with those found in the literature on other control techniques such as proportional-integral-derivative (PID) and synergetic controls shows the efficiency, superiority, and satisfactory performance of the proposed control scheme to minimize harmonic distortion under low irradiance conditions. The robustness and better dynamic performance of the proposed backstepping controller under varying irradiance conditions have also been shown.

“…Zadeh et al [24] proposed and evaluated three kinds of controllers: back-stepping, sliding mode, and fuzzy logic with the back-stepping controller demonstrating superior performance. Kolbasi and Seker [25] proposed a nonlinear inverter controller based on robust back-stepping. However, having more than two gains makes it harder for the controller to be efficient.…”

This paper presents a single-phase Photovoltaic (PV) inverter with its superior and robust control in a standalone mode. Initially, modeling and layout of the Buck-Boost DC-DC converter by adopting a non-linear Robust Integral Back-stepping controller (RIBSC) is provided. The controller makes use of a reference voltage generated through the regression plane so that the operating point corresponding to the maximum power point (MPP) could be achieved through the converter under changing climatic conditions. The other main purpose of the Buck-Boost converter is to act like a transformer and produce an increased voltage at the inverter input whenever desired. By not using a transformer makes the circuit size more compact and cost-effective. The proposed RIBSC is applied to an H-bridge inverter with an LC filter to produce the sinusoidal wave in the presence of variations in the output to minimize the difference between the output voltage and the reference voltage. Lyapunov stability criterion has been used to verify the stability and finite-time convergence of the overall system. The overall system is simulated in MATLAB/Simulink to test the system performance with different loads, varying climatic conditions and inverter reference voltages. The proposed methodology is compared with a back-stepping controller and Proportional Integral Derivative (PID) controller under rapidly varying climatic conditions. Results demonstrated that the proposed technique yielded a tracking time of 0.01s, a total harmonic distortion of 9.71% and a root means square error of 0.3998 in the case of resistive load thus showing superior control performance compared to the state-of-the-art control techniques.

“…Otros, como en (Bagheri and Komurcugil, 2022;Guo et al, 2019) hacen uso de técnicas de control no lineal como los modos deslizantes empleando estrategias de reducción de chattering para evitar el efecto de ruido que provocaría en sistemas eléctricos. En (Kolbaşi and Seker, 2019) se propone el uso del control robusto basado en el backstepping con el objetivo de dar seguimiento a una referencia de voltaje a través de una acción de control suave. En (Omar et al, 2019) se diseña un control backstepping para un inversor monofásico que opere de manera independiente a la red eléctrica, el controlador se realimenta de tres señales siendo estas el voltaje en la carga, la corriente que le suministra a la carga y la corriente de la bobina.…”

The following paper presents the modeling and design of a backstepping controller based on saturation functions for a single-phase off-grid inverter system. The proposed controller consists of an algorithm that modifies the controller gains as a function of the error, which is intended to avoid the windup effect and to adapt to changes in system parameters, such as inverter load. The objective of the bakstepping controller acting on the system is to reduce the tracking error and improve the voltage quality at the inverter output by reducing the total harmonic distortion. The results of the backstepping controller with saturated gains are compared against backstepping with constant gains in order to test its performance improvement.
