1. A method comprising:
increasing a resilience of a first section of a regional electric transmission grid, that is part of a synchronized interconnection, serving at least two independent electric loads of pre-selected critical infrastructure facilities served by different substations on the regional electric transmission grid by detecting or anticipating a problem in or threats to the regional electric transmission grid, wherein the regional electric transmission grid comprises the first section serving the at least two independent electric loads of the pre-selected critical infrastructure and a second section, wherein the first section and the second section are configured to operate together during normal operating conditions under control of a first control system and a first cybersecurity system for the regional electric transmission grid, wherein neither of the first section or the second section is (a) a microgrid that comprises a group of interconnected loads and distributed energy resources (DER) which is under control independent from the regional electric transmission grid during normal operating conditions, and problem, threat or anticipated problem operating conditions or (b) a system containing only distributed energy resources (DER) which is under control independent from the regional electric transmission grid during normal operating conditions, and problem, threat or anticipated problem operating conditions, wherein the first section is connected to the second section via at least two electric transmission connections which provide for current flow at transmission voltages between the first section and the second section under normal operating conditions, and comprises transmission equipment and at least one of central station power generation equipment or distributed generation equipment capable of serving the at least two independent electric loads within the first section independently of the second section, wherein the second section comprises a remainder of the regional electric transmission grid but excluding the first section;
determining that disconnection of the first section from the second section would enable the first section to continue operation to serve the at least two independent electric loads of the pre-selected critical infrastructure during the problem, anticipated problem or threat, wherein the first section is disconnected from the second section via the at least two electric transmission connections when the problem is detected or anticipated;
controlling an operation of the first section involving movement of power over electric transmission lines after disconnection, during the problem, anticipated problem or threat to balance power generated within the first section with the at least two independent electric loads within the first section, by using a second control system and a second cybersecurity system for the first section that is independent of the first control system and first cybersecurity system;
delivering power to the at least two independent electric loads within the first section;
monitoring, via the second control system, a generation, a transmission, or a distribution of electricity or electric loads within the first section during a period of disconnection;
resynchronizing the first section and the second section of the regional electric transmission grid upon reconnection of the first section and the second section; and
restoring control and operation of the first section to the first control system and the first cybersecurity system when the problem or threat is resolved or no longer anticipated.
