Improvement of the Transient Stability of Grid Connected Microgrids Including Inverter Based DGs Using DSTATCOM

Microgrids are becoming popular because they can meet the needs of people who want energy from natural sources and are using more and more energy. Itis important to emphasis on numerous safety and control features of a microgrid. During the change from following the grid to forming the grid, the instability of frequency and voltage due to control problems becomes the main concern. Then, the paper uses a method to control the frequency and voltage of power generators so they can share power efficiently. Furthermore, we are suggesting a way to handle situations when there is not enough control and to keep the system strong. We are proposing a method to prioritize and shed different parts of the system in three stages to help with this. The effectiveness of the method depends on how quickly the system reacts and is calculated based on the changing speed of the frequency. The process combines the battery capacity system and D-STATCOM in the microgrid to provide a reliable power supply to customers for a long time without sudden power cuts. We test the proposed procedures on a smaller version of an IEEE 13-bus microgrid using MATLAB. We recreate the time-domain to see if the procedures work well.
