Investigation of transient stability in a distribution system with renewable energy integration

Abstract

Nowadays, renewable energy is extensively participating in the energy production worldwide. This report investigates the integration of the renewable distributed energy in existing power systems while assuring the systems stability. In this paper the relation between the distributed generations (DG) especially induction generator type with respect to transient stability is examined. For the DG to ride through faults the critical clearance time or CCT becomes an essential criterion; in this paper CCT is obtained theoretically and compared with the simulation results. This paper analyzes how transient stability margin is improved using a STATCOM at distribution level or by the implementation of inverterbased distributed generations. A simulation was designed to investigate the proposed approaches using MATLAB/SIMULINK.
