TRANSIENT STABILITY ANALYSIS AND ITS INTENSIFICATION IN MICROGRID

Abstract—Technology evaluation, environmental concerns are often vast and messy in electrical power system. Hence, the study of transient stability plays a vital role for secured and planning operation in the power system. Today’s challenge is the implementation of renewable energy into existing power system. Thus, microgrid an effective means of integrating distributed energy source. However, low inertia power electronics interface make microgrids sensitive to disturbance. It is therefore essential to investigate the transient stability characteristic of microgrid in detail. This paper presents the transient stability analysis of microgrid under different loading conditions and system voltage and critical clearing time is observed. The test system is simulated and stability analysis is carried out using MATLAB/Simulink Library. Index Terms—Transient stability, Microgrid, Distribution generation (DG), WEC
