1. A supervisory system comprising:
- a sensing circuit configured to dynamically determine the available load capacity of an AC power supply circuit downstream of a substation of a high-voltage power transmission and distribution grid, the AC power supply circuit having a limited capacity for supplying power to one or more electrical loads;
a reporting circuit configured to report the dynamically available load capacity of the AC power supply circuit;
a controller configured to respond to the reported dynamically available load capacity of the AC power supply circuit; and
an input/output communication interface communicatively linking the controller with one or more electrical loads, potential electrical loads, and/or other devices on the AC power supply circuit;
wherein the reporting circuit is configured to send information to a first load or device in a first time period, wait for a second time period, and then send information to a second load or device in a third time period.

Abstract
Systems and methods for operation of an AC power supply distribution circuit that has a limited supply capacity rely on dynamically measured available load capacity to regulate operation of the AC power supply circuit, and existing and potential loads, to avoid fault or damage.

28. A method, comprising:
-
dynamically determining an available load capacity of an AC power supply circuit downstream of a substation in a high-voltage power transmission and distribution grid, the AC power supply having a limited total capacity for supplying power to one or more electrical loads; reporting the dynamically available load capacity of the AC power supply circuit to one or more present electrical loads, potential electrical loads, and/or other devices connected to the AC power supply circuit; and controlling operations of one or more components of the AC power supply circuit and/or the existing or potential electrical loads in response to the dynamically available load capacity information; wherein the reporting includes sending information to a first load or device in a first time period, waiting for a second time period, and then sending information to a second load or device in a third time period. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37)
