Photovoltaic (PV) has become the alternative form of clean energy generation world-wide. Many power utilities have embraced this alternative source of power generation and integrating the power to the grid. This research study provides insights on the effects of high levels of Photovoltaic (PV) generation integration on the utility grid with particular emphasis on the South African utility grid. The...
The aim of this paper is to present a general description about the method called Extremum Seeking Control (ESC), and its applications in the nonlinear systems, which have an unknown dynamics. The system we are interested in is the photovoltaic system. This technique presents a solution on real time optimization control problems.
This paper aims to investigate problem of the integration of a photovoltaic site been submitted under local weather conditions, located at Bouira city (Algeria) in a three-phase grid. In fact, Algeria has great assets to embark on the exploration of photovoltaic energy whether by its solar potential or by its large area. The study of photovoltaic systems with their integration into conventional electrical...
The work presented in this paper aims for the study and implement an acquisition system and remote control of a photovoltaic pumping station. The proposed system, built around an Arduino board and a GSM module enables real time characterization parameters of a photovoltaic pumping station and transmission of different measures to the operator by GSM network. Indeed, using his mobile phone, the operator...
This study presents the principle of the MPPT command. The command techniques most used in MPPT control are reviewed and analyzed such as: Observation and Perturbation (O & P) and Conductance Incrementing (CI). The aim of this study is the association of the Fuzzy Logic command with the MPPT command, then analyzing and comparing its behavior with other techniques (O & P and CI) used in the...
The use of multilevel inverters in Photovoltaic (PV) applications have attracted major attentions in both industry and academic research. This paper presents a PV system based on a single-phase Quasi-Z-Source (QZS) multilevel inverter with a great reduction in number of switches. The introduced inverter is based on a Multilevel DC link (MLDCL) structure and an H-bridge inverter. The MLDCL consists...
In this work, we analyze the design and simulation of the electrical operation of a photovoltaic (PV) system adapted by a numerical intelligent controller (MPPT controller) ensuring the pursuit of the maximum power supplied by the photovoltaic generator despite the change of weather conditions. Particularly, we present the effect of meteorological conditions on the performance of a photovoltaic generator...
This paper presents a simulation approach which can help in the preliminary power sizing design of a grid-connected PV system based on a single inverter configuration. Given a nominal peak power of the PV array, this simulation procedure leads to the PV inverter maximum rated power which maximizes the yearly injected energy to the grid.
In this paper a simulator of photovoltaic generators with programmable electrical characteristics is presented. The proposed system has the ability to generate the current-voltage curves of photovoltaic modules under any desirable insolation and temperature conditions. The system is also capable of integrating any maximum power point tracking algorithm under a unified control. The simulatorpsilas...
