The use of renewable energy sources plays an irreplaceable role in remote areas where the power grid is not available. Photovoltaic power conversion (PV) and wind power conversion are the main types of renewable energy sources used. Hybrid systems are considered the most efficient solution for remote areas that are not connected to the centralized power grid. Renewable energy is attracting the attention of researchers around the world. The main challenge is to combine the various existing sources into a single model in order to benefit from each of them, while complementing each other's disadvantages. The possibilities of managing combined hybrid systems based on renewable energy sources are currently not thoroughly studied. To increase the generation of electrical energy and reduce losses during the operation of these systems, it is necessary to conduct research aimed at improving the interactions of individual nodes of the proposed generation systems and improving the calculation methods for hybrid power plants. The integrated use of solar and wind generation systems can significantly improve energy performance and increase the generation of electrical energy. This paper proposes a method for integrating a solar photovoltaic system, a wind turbine, and a diesel generator connected to a load. An additional load is also connected to the system to absorb excess power. The hybrid system model was developed in MATLAB / Simulink. A controller based on an adaptive neuro-fuzzy inference system was developed and the system analyzed in terms of energy production and consumption. The results obtained show the degree of increase in the reliability and stability of the system.
The findings of a study of a combined wind-photovoltaic installation for use in the Najaf governorate’s energy sector are presented in this article. The suggested hybrid system is for serving community customers in Iraq, as well as for the country's energy sector. Iraqi consumers are constantly short of electricity, and the proposed approach of combining solar and solar installations to generate energy will assist to alleviate this problem. In the presented studies, the authors show a total increase in the efficiency of the mini-energy complex due to the combined generation of electric energy by converting the wind flow and solar radiation. This work is devoted to the analysis and modeling of a small autonomous hybrid wind-photo-energy system. The paper presents a simulation of the operation of a wind power installation. During the study, parameters such as the angle of inclination, rotor diameter, wind speed, etc. are taken into account. The photovoltaic installation is simulated under realistic conditions, such as silicon cell temperature, sun insolation, and so on. The MATLAB computer program was used to solve mathematical models of small horizontal axes of wind turbines and solar systems. An experiment was conducted with low-power installations. The findings reveal that when hybrid wind-solar systems are used to power Iraq's energy complex, the total output of the hybrid installation increases dramatically. Furthermore, the output of electric energy from wind and solar installations varies throughout the year. During summer months, mainly photovoltaic batteries operate, while in winter months, wind turbines make the main contribution to the generation. As a result, the joint work of wind and solar installations to generate electrical energy helps to establish a more uniform generation throughout the year.
