SYSTEMS AND METHODS FOR MINIMIZING ENERGY COSTS FOR A POWER CONSUMPTION SYSTEM THAT HAS ACCESS TO OFF-GRID RESOURCES
First Claim
1. A method, comprising:
- at a computer system having one or more processors and memory storing one or more programs executed by the one or more processors;
calculating a load prediction arising from an electrical-power consumption entity over a prospective time period;
calculating a predicted off-grid electrical-power supply from an off-grid electrical-power supply over the prospective time period;
minimizing, for a respective time interval in a plurality of time intervals, a calculated amount of electrical-power to import from a power grid during the respective time interval, in accordance with output from a cost function, wherein the cost function uses;
(i) a multi-component time of use tariff schedule associated with the power grid that includes a first power rate during a prospective time period and second power rate during a second time period, wherein the first power rate is other than the second power rate,(ii) the load prediction over the prospective time period,(iii) the predicted off-grid electrical-power supply over the prospective time period, and(iv) a state of a rechargeable battery, wherein the plurality of time intervals collectively accounts for the prospective time period; and
for at least one interval in the plurality of time intervals,importing, from the power grid, the corresponding calculated amount of electrical-power corresponding to the at least one interval.

Abstract
A method includes: calculating a load prediction arising from an power consumption entity over a prospective time period; calculating a predicted off-grid power supply from an off-grid power supply; minimizing, for a respective time interval, a calculated amount of electrical-power to import from a power grid, in accordance with output from a cost function; and, for at least one interval, importing, from the power grid, the corresponding calculated amount of electrical-power corresponding to the at least one interval. The cost function uses: (i) a multi-component time of use tariff schedule associated with the power grid that includes a first power rate during a prospective time period and second power rate during a second time period, (ii) the load prediction over the prospective time period, (iii) the predicted off-grid electrical-power supply over the prospective time period, (iv) a state of a rechargeable battery.
