“…An alternative method is based on measuring and processing the current and/or voltage ripple due to the switching behavior of the converter connected to the PV panels array. This method is known as "ripple correlation control", firstly proposed by Midya (1996) and successively utilized by Brambilla (1999) and Logue (2001). However, for small power PV generation systems, high switching frequency converters are usually adopted, reducing the residual voltage and Fig.…”

A maximum power point tracking algorithm for single-stage converters connecting photovoltaic panels to a single-phase grid is presented in this paper. The algorithm is based on the processing of current and voltage low-frequency oscillations introduced in the PV panels by the single-phase utility grid. The algorithm has been developed to allow an array of PV modules to be connected to the grid by using a single-stage converter. This simple structure yields higher efficiency and reliability when compared with standard solutions based on double-stage converters configuration. The proposed maximum power point tracking algorithm has been numerically simulated and experimentally verified by means of a converter prototype connected to a single-phase grid.

Abstract-This paper proposes a voltage compensator (VC)for a grid-connected photovoltaic generation system to compensate shadowing phenomena. The solar cell array in this paper is composed of several strings using the same maximum power point. The proposed VC is an isolated DC-DC power converter which supplies a voltage to compensate for the voltage of shaded string in order to maintain the output voltages of every strings of a solar cell array to be the same. Therefore, the problem of multi-peaks in P-V curve of solar cell array caused by shadowing in a solar generation system can be solved. Therefore, the power generation in gridconnected photovoltaic generation system can be increased. A solar cell array comprising two strings is tested to verify the performance of the proposed VC. The experimental results are as expected.

Tracking the Maximum Power Point (MPP) of a photovoltaic (PV) array is usually an essential part of a PV system. The problem addressed by Maximum Power Point Tracking (MPPT) techniques is to find the voltage V MPP or current I MPP at which a PV array should operate to generate the maximum power output P MPP under a given temperature and irradiance. MPPT control methods such as the perturb and observe method and the incremental conductance method require a microprocessor or DSP to determine if the duty cycle should be increased or not. This paper proposes a simple and fast analog MPPT method. The proposed control scheme tracks the MPP very quickly and its hardware implementation is simple when compared with the conventional techniques. The new algorithm can successfully track the MPP even in the case of rapidly changing atmospheric conditions. In addition, it has higher efficiency than ordinary algorithms.
