An economic parallel processing technology for faster than real-time transient stability simulation

The need to increase power flows is forcing electric power companies to consider the rapid determination of transfer and security limits in energy management centers. At the present time, transient stability transfer limits are generally calculated off-line due to the limitations of numerical computers. This paper introduces an innovative approach for simulating transient stability based on the use of a new type of chip technology designed for real-time image processing. Power system equations in matrix form are solved by means of rapid matrix operation techniques on the PULSE (parallel ultra large scale engine) technology, resulting in outstanding low cost performance. This paper confirms the efficiency of this approach on the 9 bus Western Systems Coordinating Council (WSCC) test power system. Simulation results based on a preliminary version of the PULSE technology clearly indicate that economic, faster than real-time transient stability simulation is feasible for large networks.
