“…The PV array is characterized by a non-linear behavior that changes significantly with the operating conditions, e.g. irradiance level, shades, temperature, among others, which makes difficult to predict the voltage and current to guarantee the maximum power production [3]. The operation point in which the PV array provides its maximum power is named maximum power point (MPP) [4], [5].…”

“…The operation point in which the PV array provides its maximum power is named maximum power point (MPP) [4], [5]. Then, the main objective of the control strategy in a PV system is to ensure the system operation around its MPP (Maximum Power Point Tracking -MPPT) in whichever load and environmental conditions [3]- [6]. In the literature, the most commonly used MPPT solutions are the incremental conductance (IC) and the perturb and observe (P&O) [7], where the P&O is widely adopted due to its simple implementation and tracking efficiency [4], [8].…”

In many grid-connected applications a dc/dc switching converter is usually connected between the PV modules and the inverter. This paper presents an improved procedure to design a sliding controller for the PV system, which drives the PV voltage to follow a reference provided by an external MPPT algorithm and mitigates the perturbations caused by the irradiance changes and oscillations in the bulk-voltage. By considering that the switching surface is the linear combination of the input capacitor current and the PV voltage error, the proposed design exhibits advantages in comparison with existing solutions that rely in the linearization of inner current loop dynamics. The proposed integral procedure, by taking also into account the effects in the closed loop system dynamics of a reference filter, ensures a stable sliding regime in all the desired operation range of the system, while the settling time and overshoot of the PV voltage required by an MPPT algorithm are provided. Differently from a previous similar but less rigorous approach, the switching function and reference filter parameters are obtained by numerically solving a set of nonlinear equations. Simulations and experiments were used to demonstrate the efficiency of the proposed solution in presence of environmental and load perturbations. 0885-8993 (c)

“…At the same time the computing speed of modern digital signal processors (DSP) has multiplied and enabled modern control strategies like fuzzy control [3], adaptive control [4], sliding mode control [5] or predictive control algorithms [6]- [13] to be applied in industrial power electronic converter systems.

Abstract:The implementation of maximum power point tracking (MPPT) schemes by the ripple correlation control (RCC) algorithm is presented in this paper. A reference is made to single-phase single-stage multilevel photovoltaic (PV) generation systems, when the inverter input variables (PV voltage and PV current) have multiple low-frequency (ripple) harmonics. The harmonic analysis is carried out with reference to a multilevel configuration consisting of an H-bridge inverter and level doubling network (LDN) cell, leading to the multilevel inverter having double the output voltage levels as compared to the basic H-bridge inverter topology (i.e., five levels vs. three levels). The LDN cell is basically a half-bridge fed by a floating capacitor, with self-balancing voltage capability. The multilevel configuration introduces additional PV voltage and current low-frequency harmonics, perturbing the basic implementation of the RCC scheme (based on the second harmonic component), leading to malfunctioning. The proposed RCC algorithm employs the PV current and voltage harmonics at a specific frequency for the estimation of the voltage derivative of power dP/dV (or dI/dV), driving the PV operating point toward the maximum power point (MPP) in a faster and more precise manner. The steady-state and transient performances of the proposed RCC-MPPT schemes have been preliminarily tested and compared using MATLAB/Simulink. Results have been verified by experimental tests considering the whole multilevel PV generation system, including real PV modules, multilevel insulated-gate bipolar transistor (IGBT) inverters, and utility grids.
