Segmentation with Grid Shock Absorbers for Enhancing the Reliability of Large Transmission Interconnections

History recorded a great debate between the principal founders of the modern electric power industry: Thomas Edison and George Westinghouse. DC Interconnect (DCI) has been developing a concept that takes advantage of both ac and dc technologies to meet future needs in a cost effective manner. The article asserts "It seems the great debate is, after all, a draw; the power industry can best achieve improved reliability, power transfer capability, and market operations by taking advantage of both ac and dc technologies."

The DCI / EPRI collaborative research project entails simulations of a regional segmentation limited to the Northeastern part of the Eastern Interconnect. System responses to severe disturbances with and without back-to-back voltage-sourced converters inserted in certain ac ties were compared. Remarkable improvement in reliability performance of the segmented system was demonstrated and fully documented.

The results confirmed earlier DCI analyses. Segmenting large grids is the preferred and inevitable solution to the challenges facing multi-regional interconnections. The application of this technology will reinforce and enhance the performance of the existing ac infrastructure.
