Abstract: Reliable, automated or semi-automated systems/methods that address technical problems involved in electrical power grid design, planning, and operation/control are disclosed. Applications include the technical problem of optimizing adjustments of, and/or infrastructure additions to, large electrical power grids in response to changed operating conditions or planned facility additions that may impact their reliability. An automated or semi-automated system for identifying appropriate adjustments to the electrical power grid and/or addition of new facilities, and the methods and executable computer instructions that enable them, are disclosed.
