1. A method of managing an outage condition associated with at least one portion of a power grid, the method executable with computer having at least one processor and memory and comprising: receiving a plurality of event messages, wherein each of the plurality of event messages is indicative of a condition associated with the at least one portion of the power grid; determining, using the at least one processor, that at least one of the plurality of event messages is indicative of an outage condition associated with the at least one portion of the power grid; retrieving at least a portion of grid state data, wherein the grid state data is representative of current demand conditions of the power grid; retrieving at least a portion of connectivity data, wherein the connectivity data is representative of a physical configuration of the power grid; verifying, using the at least one processor, presence of the outage condition based on the grid state data and connectivity data from devices of the power grid; receiving, from a high-level entity of the power grid selected from the group consisting of a section, a feeder circuit, and a data management system (DMS), a suspension message to suspend processing the plurality of event messages from at least one device in the at least one portion of the power grid, the at least one device comprising a line sensor, wherein the suspension message is indicative of a detected undesired condition of the line sensor; determining that the line sensor is in a suspend filter state when the suspension message exists while the high-level entity is in a state selected from the group consisting of: (i) performing a health check of the line sensor; (ii) an outage sensed condition; (iii) an outage confirmed condition; and (iv) a fault sensed condition; suspending processing of the event messages originating from the line sensor while in the suspend filter state; and terminating the suspend filter state responsive to receipt of a resume message from the high-level entity, thereby returning the line sensor to normal operation.
