Implementation of a distributed parallel computing architecture for transient stability constrained ttc evaluation

A task level intelligent computing architecture, called as smart workstation cluster distributed parallel computing model, is presented for transient stability constrained total transfer capability (TTC) evaluation of large scale interconnected power system with respect to a specified contingency set. The proposed intelligent distributed parallel computing mode can effectively integrate the heterogeneous distributed computing resources around internet and implement the dynamic load balancing so as to make full use of the whole system computing performance. Furthermore, the dynamic scalability and fault-tolerance of the proposed computing architecture are analyzed and developed as well. The case studies have been carried out on a real-sized Chinese power system, and results demonstrate the practicability and effectiveness of the proposed model.
