Investigation of transient stability of DG integration in Lebanon a simulation using MATLAB/SIMULINK

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 system's 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 inverter-based distributed generations. A simulation was designed to investigate the proposed approaches using MATLAB/SIMULINK.
