THE EFFECTS OF RENEWABLE ENERGY SOURCES ON VOLTAGE STABILITY

Power systems are exposed to significant structural changes in recent years. One of the main reasons for this is the integration of renewable energy sources into power systems. Today, especially renewable energy sources such as wind and sun are densely connected to power systems at various points. As a result, changes occur in the structures of the power systems. These structural changes also affect the parameters of power systems. One of these parameters, voltage stability, is considered as an important criterion in terms of the quality of electric energy and the continuity of electric energy. In this study, the voltage stability analysis of the power system was made by adding the renewable energy sources to various points on six bus power system. The review focuses wind power plants heavily used in renewable energy sources. Various scenarios have added renewable energy sources at various levels to the consumption points of the power system. As a result of these scenarios, stability limit values of the power system are investigated. The study was performed through the Power World simulation program. In addition, the P-V curves of the buses are plotted with continuous load flow. According to the results obtained, it is observed that the system has improved stability limits, voltage and power.
