Abstract

In one embodiment, a system includes a coordinated distribution optimization (CDO) system. The CDO system includes a processor configured to coordinate execution of a plurality of independent electrical network applications. Each of the plurality of independent electrical network applications is configured to alter one or more operational parameters of a power grid based on one or more respective objectives and based on power grid operational data, and the execution of the plurality of independent electrical network applications is coordinated by the CDO system to block the power grid from entering an abnormal state. The CDO system further comprises a network interface configured to receive the power grid operational data from a controller of the power grid, and wherein the power grid operational data comprises current values for the one or more operational parameters of the power grid.
