Transient stability and other important aspects of power system in Multi-DG environment

Abstract

Modern world smart grid is a combination of a reliable communication network, robust central generation and strategic commanded Distributed Generations (DG). Ungoverned penetration of DG to balance inflationist load will encourage grid instability. This paper proposes a modest methodology to analyse the transient stability of the electrical network with distributed generation and its effect on other important aspects like voltage stability, overall loss minimization, economic benefits, short circuit capacity, power quality and reliability of power system. The possible events have been simulated with 33 bus radial distributed system. The case studies have been extended to single and multi DG environment. ETAP 7.5 and MATLAB v10 have been used for simulation of case studies. Simulation results validate the promising outcome of this work.
