Abstract

Systems and methods for synchronizing switching within a power distribution network are provided. A switch plan for restoring electrical power to a power distribution network following a power outage may be identified by a control system. The control system may be associated with a power utility and may include one or more computers. A plurality of switching operations associated with the switch plan may be identified by the control system. The plurality of switching operations may include at least one automatic switching operation and at least one manual switching operation. A synchronized execution of the plurality of switching operations may be coordinated by the control system.

receiving, by the control system, communication from the one or more components of the power distribution network, wherein the switch plan is dynamically modified based upon the communication received;

identifying, by the control system, a plurality of switching operations associated with the switch plan, the plurality of switching operations comprising at least one automatic switching operation and at least one manual switching operation;

directing, by the control system, to a mobile user device a communication of a message to execute the at least one manual switching operation to facilitate execution of the switch plan;

receiving, by the control system, an indication that at least one switching operation has been completed;

dynamically modifying, by the control system, the switch plan based at least in part on the received indication, and one or more conditions associated with the power distribution network, wherein the one or more conditions comprises one or more of;

phase balancing analysis, load balancing analysis, voltage conditions, frequency conditions, reactive power conditions, or maintenance information;

coordinating, by the control system, a synchronized execution of the plurality of switching operations based at least upon the communication received from the one or more components, indications that the switching operations have been completed, and/or the one more conditions associated with the power distribution network, wherein the synchronized execution facilitates the dynamically modified switch plan and executes a next switching operation included in the plurality of switching operations based at least in part upon the received indication that one switching operation has been completed;

identifying, by the control system based at least in part on the switch plan, an area of the power distribution network isolated as a result of the plurality of switching operations; and

directing, by the control system, an optimization of maintenance associated with the identified area, wherein the directing comprises;

communicating, by the control system to an asset management system, information associated with a power outage for the isolated area, wherein the asset management system schedules maintenance associated with the isolated area based at least in part on the received information;

receiving, by the control system from the asset management system, scheduled maintenance information for the isolated area; and

modifying, by the control system based at least in part upon the scheduled maintenance information, the switch plan.

2. The method of claim 1, wherein coordinating the synchronized execution of the plurality of switching operations comprises:

determining, by the control system, an order for executing the plurality of switching operations; and

directing, by the control system based at least in part upon the determined order, the synchronized execution of each of the plurality of switching operations.

3. The method of claim 2, wherein directing the synchronized execution of each of the plurality of switching operations comprises:

determining, by the control system for each of the plurality of switching operations, whether the switching operation is an automatic switching operation or a manual switching operation; and

directing, by the control system based at least in part on the determinations, the synchronized execution of the switching operation.

4. The method of claim 3, wherein it is determined that the switching operation is an automatic switching operation, and wherein directing the synchronized execution of the switching operation comprises:

directing, by the control system, communication of a command to execute the switching operation to an automatic switching control system.

5. The method of claim 1, further comprising:

directing, by the control system, conduction of a load balancing analysis within the power distribution network; and

modifying, by the control system based at least in part upon the load balancing analysis, the switch plan.

6. The method of claim 1, further comprising:

communicating, by the control system to a distributed energy resource, an indication that one or more switching operations have been executed,

wherein the distributed energy resource determines, based at least in part on the indication, an effect of the one or more switching operations on a power delivery associated with the distributed energy resource.

7. A system, comprising:

at least one memory configured to store computer-executable instructions; and

at least one processor configured to access the at least one memory and execute the computer-executable instructions to;

direct notifications to one or more components of the power distribution network, wherein the one or more components comprises one or more of;

a load balancing controller, one or more distributed energy resources (DERs), or an asset management system;

receive communication from the one or more components of the power distribution network, wherein the switch plan is dynamically modified based upon the communication received;
