Distributed main-tie-tie-main transfer control scheme

A main-tie-tie-main (MTTM) power system comprising:

• a first main protection relay controlling a first utility breaker;
• a second main protection relay controlling a second utility breaker;
• a first tie protection relay controlling a first tie breaker;
• a second tie protection relay controlling a second tie breaker;
• and
• a common bus communicatively connecting the first main protection relay, second main protection relay, first tie protection relay, and second tie protection relay together, wherein each of the first main protection relay, second main protection relay, first tie protection relay, and second tie protection relay is connected to the common bus via one or more communication lines,
• wherein the first main protection relay and the first tie protection relay are connected together via a first paired line, and
• wherein the first main protection relay controls the first tie breaker via the first paired line and the first tie protection relay controls the first utility breaker via the first paired line.
