1. A load management system comprising:
- a first electrical grid;
one or more power sources coupled to the first electrical grid, each power source coupled to a respective source control system;
a second electrical grid coupled to the first electrical grid by a power conversion system;
a plurality of loads coupled to the second electrical grid;
a plurality of load control systems, each load control system respectively coupled to the one of the loads; and
a grid control system configured to perform operations comprising;
receiving, from the plurality of load control systems, a plurality of priority ratings uniquely assigned to each of the plurality of loads, wherein the plurality of priority ratings for each of the plurality of loads are based on a time of day and each of the plurality of priority ratings individually change based on the time of day;
receiving source information from each source control system of the first electrical grid, wherein source information includes an envelope of power levels that the one or more powers sources can provide at various times;
based on the source information, the time of day, and a priority rating for each of the plurality of loads for a particular time of day, determining a respective load instruction for each of the load control systems; and
sending the load instructions to the load control systems, causing each load control system to adjust power drawn from the second electrical grid by the load control system'"'"'s respective load based on the load control system'"'"'s respective load instruction.

Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for electrical load management. One of the systems includes a first electrical grid, one or more power sources coupled to the first electrical grid, a second electrical grid coupled to the first electrical grid by a power conversion system, one or more loads coupled to the second electrical grid, and one or more load control systems coupled to the one or more loads. A grid control system is configured to receive source information from the first electrical grid and send load instructions to the load control systems based on the source information.

11. A method performed by a grid control system, the method comprising:
-
receiving, from a plurality of load control systems, a plurality of priority ratings uniquely assigned to each of a plurality of loads, wherein the plurality of priority ratings for each of the plurality of loads are based on a particular time of day and each of the plurality of priority ratings individually change based on the time of day; receiving source information from one or more source control systems of a first electrical grid having one or more power sources coupled to the first electrical grid and each of the one or more power sources uniquely coupled to a source control system; based on the source information, the time of day, and a priority rating for each of the plurality of loads for the particular time of day, determining a respective load instruction for each of the load control systems, the load controls systems each being coupled to a respective load coupled to a second electrical grid, the second electrical grid being coupled to the first electrical grid by a power conversion system; and sending the load instructions to the load control systems, causing each load control system to adjust power drawn from the second electrical grid by the load control system'"'"'s respective load based on the load control system'"'"'s respective load instruction. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
