Abstract:
1. A computer-assisted method of electrical energy load shifting utilizing an electrical energy storage device connected to receive electrical energy from an electrical power grid, comprising the steps of: establishing a budget of unreserved cycles of discharging and charging the electrical energy storage device for load shifting purposes within a given time period, the budget of unreserved cycles is based on rated cycles of the electrical energy storage device and reserved cycles of the electrical energy storage device; establishing a schedule for load shifting within sub-parts of said time period, based upon said budget and input data regarding multiple rate levels applicable to electrical energy available from the electrical power grid during the sub-parts of said time period; and executing load shifting cycles within one or more of said sub-parts of said time period, in accordance with said schedule, by discharging electrical energy stored in said electrical energy storage device in a first interval for which a first rate is applicable to energy available from the grid, and charging said electrical energy storage device with electrical energy obtained from the grid during a second interval for which a second rate lower than said first rate is applicable to energy obtained from the grid.
