Abstract:

Today, energy demands are increasing gradually. In order to meet the requested energy, it is necessary to use the developing technological devices and methods. With the implementation of these structures, energy efficiency is ensured as well as preventing environmental pollution. In daily life, renewable energy source systems preferred in order to provide the energy requirements and to use sources without harming the environment. The sun, which is one of the renewable energy sources, is first of the sources used for energy production today. But, the efficiency of photovoltaic (PV) panels are not sufficient in energy conversion. This situation limits the usage area. Photovoltaic systems operate depending on different environmental parameters such as temperature and radiation. All the time, the energy produced isn't at the same level under variable conditions. The maximum power point of photovoltaic systems is tracked. With always operating the system at this point, maximum energy efficiency is achieved. Energy efficiency is not only about production, at the same time, about managing energy. In this study, it has been tried to increase the energy efficiency of the system by using MPPT algorithms and the developed energy management system in the case of working with constant temperature and variable radiation values in photovoltaic systems. The all system was modelled in the MATLAB/Simulink. The simulation results were interpreted.
