Abstract
In order to improve the efficiency of photovoltaic panels it is necessary to introduce the technique of Maximum Power Point (the technique of the MPPT). In the literature, several strategies are mentioned, among which the perturbation and observation (P&O) algorithm. The aim of this work is to a simulation study in MATLAB of a photovoltaic panel connected to the network using DC-DC and DC-AC converters. DC Boost converter is checked by the MPPT command to adjust the output voltage of the photovoltaic panel and maximize the power produced by the photovoltaic panel. The PI controller is used to control the inverter three-phase to make the connection of the photovoltaic panel to a three-phase electrical network.
Highlights
The renewable energy market has grown rapidly over the past decade due to deteriorating environmental quality and the escalating price of fossil fuels.Renewable energy has become today like a potential solution for pollution because it is more appropriate and more efficient and clean.The rapid development of solar energy has gradually appeared in the form of small electrical installations connected to the Low Voltage (LV) network and solar farms directly connected to the Medium and High Voltage (HV, MV) network.In order to improve the efficiency of photovoltaic panels it is necessary to introduce the technique of the Maximum Power Point
