Power Engineering Letters Transient Stability Analysis of a Distribution Network With Distributed Generators

Abstract—This letter describes the transient stability analysis of a 10-kV distribution network with wind generators, microturbines, and CHP plants. The network being modeled in Matlab/Simulink takes into account detailed dynamic models of the generators. Fault simulations at various locations are investigated. For the studied cases, the critical clearing times are calculated. Results obtained from several case studies are presented and discussed. Index Terms—Critical clearing time, distributed generation, dis-tribution network, power system protection. I
