Integration of wind and solar hybrid power generation system into the grid and investigation of power quality control

Today, conventional energy sources are rapidly depleting. In contrast, increasing energy demand triggered the need for renewable energy sources. The disadvantages of conventional basic energy sources such as the harmful effects on the environment and the problem of transportation to resources have led to the shift to renewable energy sources. With the increasing use of renewable energy sources in energy demand, the use of these energy sources in electrical energy production is also increasing. The use of wind and solar energy, which is one of the renewable energy sources, in electricity generation, has become widespread. The reason for this is that these types of energy do not need any fuel and are clean and do not have any harmful effects to the environment. Hybrid power generation systems have been developed by taking advantage of wind and solar energy. In this study thesis, the design and analysis of a grid connected hybrid electrical power system consisting of wind and solar power generation system using power quality and fuzzy logic and classical logic controller (PI) methods will be carried out. The design will be designed with photovoltaic panels and wind turbines in Matlab / Simulink environment. Frequency, phase, voltage, power and harmonic measurements of hybrid power generation system and network will be made. In addition, the voltage and frequency fluctuation times between the hybrid power generation system and the grid during the synchronization process, the voltage increases in the network when the system is unloaded, and the voltage, power, frequency, phase angle values measured in the hybrid system, load and network after synchronization will be shown separately. The performance of hybrid power generation system will be analyzed according to the graphs and measured values resulting from the simulation. Conventional energy sources are rapidly depleted today. However, energy demand continues to increase. Therefore, the need for renewable energy sources has increased. In addition, conventional energy sources have disadvantages such as harmful effects to the environment and the problem of access to resources. These reasons have largely triggered the shift to renewable energy sources. The use of renewable energy sources in energy demand is increasing. Today, the use of these energy sources in the production of electrical energy is also increasing. The use of wind and solar energy, which is one of the renewable energy sources, in electricity generation, has become widespread. The reason for this is that these energy types do not need any fuel, clean and no harmful effects to the environment. Hybrid systems have been developed by taking advantage of wind and solar energy. The hybrid system creates two or more sources together. The purpose of bringing these resources together and creating a hybrid power generation system is to ensure that the resources are used together and thus to increase efficiency. In addition, if one of the resources is absent or diminished, the energy requirement of the system from the other source will be met. The PV panels and wind turbine output to be used in the Wind and Solar hybrid power generation system, which will be modeled in our thesis, will be connected to the hybrid power inverter providing the mains power and frequency and the loads will be fed from the output. The energy, current and power values produced by the PV panels and wind turbines that make up the system, as well as the state of the panels and turbines will be recorded in the hybrid power inverter.With the help of these data, the efficiency of hybrid power generation system will be evaluated and necessary actions can be taken in order to increase efficiency. Stability in power systems is a balanced state of operation and the ability to restore the system to its former state after disturbing effects. It is extremely important that the energy to be delivered to consumers is stable and efficient. With this thesis, the electrical energy produced in the hybrid power production system is aimed at making the energy produced with fuzzy logic and making the energy produced more stable and more efficiently.
