Reliable and resilient future grid through T&D co-simulation and improved distribution systems protection using traveling-wave relays
Over the past century, US electric grid has evolved into an extremely complex and large interconnected grid identified by the National Academy of Engineers (NAE) as the greatest engineering achievement of the century. During that period, the overwhelming accepted principle was “larger or bigger the better”. The AC transmission voltage went up to 765 kV and the individual generating units were in excess of 1,000 MW. This centralized generation model was considered to be efficient and reliable way to operate the grid. This grid continued to serve the nation well. It, however, faced serious challenges ...
