Special Issue Information

Dear Colleagues,

During the first years of the development of solar photovoltaic cells and panels, they were considered to be expensive and to operate with a low efficiency. At this time, investment in photovoltaic systems was quite limited. Nevertheless, with time, the prices of PV cells and panels continued to increase due to the competitive market. This was mainly accompanied with the continuous increase in their efficiency, reliability, as well as other improved performance features. Consequently, there has been a significant increase in the employment of the solar photovoltaic systems in various applications worldwide.

Photovoltaic systems are usually connected to a power electronic converter. This allows for the extraction of the maximum power possible from photovoltaic panels and allows the generated voltage to be adjusted according to the voltage of the application in hand. In this regard, many power converters have been developed in recent decades, such as transformerless inverters, impedance source converters, zero voltage switching converters, resonant converters, etc. The objective behind the development of each of these converters was to offer advanced performance according to the application in hand. In addition to these inverters, modular multilevel converters have been employed in photovoltaic applications due to their numerous advantages, such as low switching frequency, modularity, fault tolerance, smaller output filter, etc.

To drive these power converters, control methods are used, which work by adjusting desired variables, such as input and/or output voltage levels, output voltage frequency and phase, and/or output current. Many families of control methods have been developed, such as resonant controllers, model predictive control, sliding mode, artificial neural networks, etc, which offer different performance levels, while at the same time, each of these families suffer from some deficiencies. Accordingly, to date, many research efforts are still being carried out in an effort to overcome or limit these deficiencies in their outcomes.

This Special Issue is entitled “Research Trends of Power Electronics Topologies, Modeling, and Control for Photovoltaic Systems” and is focused on presenting the latest developments in power converters and their control methods in photovoltaic applications, with particular emphasis on practical applications and problems that occur in real systems.

This paper proposes a new automatic tuning method for the proportional-integral (PI) controllers of photovoltaic irrigation systems (PVIS) without the need for any other power source or batteries. It enables the optimisation of the values of the PI parameters (Kp and Ki) automatically, eliminating the requirement for skilled personnel during the installation phase of PVIS. This method is based on the system’s voltage response when a disturbance signal is introduced through the feedforward input of the PI controller. To automatically assess the response properties, two indicators are proposed: the total harmonic distortion (THD), used to evaluate the sine response, and the total square distortion (TSD), used to evaluate the square response. The results indicate that the tuning changes for different irradiance and temperature conditions due to the non-linearity of the system, obtaining the most conservative values at maximum irradiance and temperature. The robustness of the results of the new automatic tuning method to abrupt photovoltaic (PV) power fluctuations due to clouds passing over the PV generator has been experimentally tested and the results show that the obtained tuning values make the PVIS stable, even when PV power drops of 66% occur abruptly.
