Method and system for managing a power grid

A method for data management for a power grid, the method comprising:

• sensing, using a device positioned in a section of a power grid, operational data including an electrical parameter in the section of the power grid;
• storing the operational data in a memory location of a data storage device, the data storage device associated with the device and proximate to the device;
• sending, to a central power grid authority that manages the power grid, a link to the memory location of the operational data;
• receiving, from the central power grid authority, a request for access to the operational data associated with the link included in the request;
• and
• responding to the request by transmitting to the central power grid authority the operational data of the memory location in accordance with the corresponding link included in the request.

A data management system for a power grid, the power grid comprising a central power grid authority for managing the power grid and a plurality of devices within the power grid, the data management system comprising:

• data storage associated with a device positioned in a section of the grid, the data storage being proximate to the device, the device sensing an electrical parameter in the section of the power grid, the data storage comprising a plurality of memory locations, at least one of which is allocated to store the sensed electrical parameter;
• and
• a central data storage associated with the central power grid authority, wherein the central power grid authority is configured to receive a link identifying a memory location in the data storage in which the electrical parameter is stored;
• and
• wherein the central power grid authority is configured to store the link in the central data storage;
• and
• wherein the central power grid authority is configured to access the link in the central data storage and send a request to the device requesting data associated with the link;
• and
• wherein the central power grid authority is configured to receive a response from the device comprising the electrical parameter stored in the memory location identified by the link.
