It is generally believed that following a fault, the system remains stable as long as the fault is cleared within a “critical clearing time” or CCT. This letter shows that when there is a high impedance resistive fault, there are later intervals such that if the fault is cleared within these intervals of time, the system is still stable notwithstanding that the clearing time is now larger than the...
Modeling of distributed generation and associated controllers have a considerable influence on the results of transient stability analysis. Synchronous generators and induction generators are two common types of generators which are used for distributed generation, for example in micro-turbines and wind turbines. In this paper, the effect of detail of modeling of synchronous generators on the transient...
This paper implements a full electromagnetic transient (EMT) micro-grid model based on a distribution system to show the possibility of evolving actual distribution systems to micro-grids platform. Due to necessity of different studies for a micro-grid, the success of this evolution depends on feasibility of performing complete studies using the platform. Micro-grid studies include power flow, fault...
