Today¿s electric power system is operated under increasingly stressed conditions. As electrical demand increases, the existing grid is operated closer to its stable operating limits while maintaining high reliability of electric power delivery to its customers. Protective schemes are designed to account for pressures towards unstable operation, but there is always a tradeoff between security and dependability of this protection. Adaptive relaying schemes that can change or modify their operation based on prevailing system conditions are an example of a protective scheme increasing reliability of the power system. The purpose of this work is to validate and analyze implementation of a Security-Dependability Adaptive Voting Scheme that utilizes synchronized phasor measurements and decision trees.

In early July 1864, a quickly patched together force of outnumbered Union soldiers under the command of Maj. Gen. Lew Wallace prepared for a last-ditch defense along the banks of the Monocacy River. Behind them, barely fifty miles away, lay the capital of the United States, open to attack. Facing Wallace's men were Lt. Gen. Jubal Early's Confederates. In just over a month, they had cleared the Shenandoah Valley of Union soldiers and crossed the Potomac River, invading the north for the third time in the war. The veterans in Early's force could almost imagine their flags flying above the White House. A Confederate victory near Washington could be all the pro-peace platforms in the north needed to defeat Abraham Lincoln in the upcoming election. Then came Monocacy. Over the course of the day, Union and Confederate soldiers attacked and counter-attacked, filling the fields just south of Frederick, Maryland, with the dead and wounded. By the end of the day, Wallace's men fell into retreat, but they had done their job: they had slowed Jubal Early. The fighting at Monocacy soon became known as the "e;Battle that Saved Washington."e;Determined to Stand and Fight by Ryan T. Quint tells the story of that pivotal day and an even more pivotal campaign that went right to the gates of Washington, D.C. Readers can enjoy the narrative and then easily follow along on a nine-stop driving tour around the battlefield and into the streets of historic Frederick. Another fascinating title from the award-winning Emerging Civil War Series.
