Abstract :
In the on-line assessment of the power grid to assure reliable operation, the state estimation is the front-end real-time processing of the measurement data being transmitted from the SCADA system via network and telemetry. An alternative high-performance computing platform comprising a host computer interconnected to a Field Programmable Gate Array (FPGA) via a PCI-Express bus is proposed. The predicted performance obtained from the state estimation of benchmark power grids (118 and 1648 bus systems) shows that the row-oriented Givens algorithm-specific hardware can provide an order of magnitude speedup over the software program of the same Givens rotation algorithm running on Pentium 4 M 1.7 GHz processor with 1 GB of RAM. This result indicates that algorithm-specific hardware on FPGA may provide a cost-effective solution to high-performance state estimation.
