| The green energy is an indispensable factor in our planet, since there are environmental pollution and global warming which damage the human life. The most significant way is either adaptation or implementation of the renewable energy sources practically in order to decrease the harmful effects of the fossil fuels in a vast scale. Nowadays, the initial investment cost of the renewable resources is so high, however, they have many advantages such as free energy, clean environment, and high class human life in a long time.;This paper introduces the combined energy systems which include solar, wind and battery with their grid integration. A DC and AC loads are implemented in the designed system. The solar system, wind system, battery management system and converters are modeled in Matlab/Simulink individually. After that they become integrated with the grid and a residential load. The wind and solar systems are supported by MPPT (Maximum Power Point Tracking) controllers which are Perturb & Observe and Fuzzy Logic. They are compared with each other in terms of their performance and efficiency. Also, these algorithms are analyzed at the various weather conditions. The battery system control method is based on the Fuzzy Logic controller to increase system efficiency. On the other hand, the specific market products and a residence location (Istanbul, Turkey) are selected for the proposed system design by using SAM software. The weather data of that location and specification of the equipment which are wind, solar, battery, converter, grid and load are transferred into HOMER software. Accordingly, a system schematic diagram is designed and the economic analysis is actualized with the system optimization in HOMER. |
