An Improved Voltage and Frequency Droop Control Method for Microgrids having Inverter Based Resources, Realizing the Effect of Lines R/X, M.Sc. Thesis Sharif University of Technology ; Vakilian, Mehdi (Supervisor)
Abstract
The centralized and decentralized control approaches are the most effective control approaches to be applied in micro grids. However, practically to rerduce the cost and improve the reliability, decentralized control is usually employed. Initially, this thesis discusses the components and dynamic model of the micro grid in order to evaluate the stability. Then, it introduces the decentralized control methods which can be used in a micro grid. In the next step, a sample micro gird is studied (with high ratio of lines R/X). This microgrid has three DG plants having DC voltage sources, inverter, and LCL filter. The performance of AVR controls is evaluated by combining the PQ and droop control...
