Aspects of the invention relate to system and method of storing off-peak electricity. The system includes an energy storage device electrically coupled to an electricity grid of at least one electricity provider, where the energy storage device has a storing capacity and is chargeable or dischargeable, upon demand, and a controller configured to control operation of the energy storage device such that the energy storage device is charged with the off-peak electricity at an off-peak time each day when a demand for electricity is low from the electricity grid, and is discharged at a peak time each day when the demand for electricity is high, to provide an amount of the stored electricity, to the at least one electricity provider. |

1. A system of storing off-peak electricity, comprising:
an energy storage device electrically coupled to an electricity grid of at least one electricity provider, wherein the energy storage device has a storing capacity of Woff, and is chargeable or dischargeable, upon demand; and a controller configured to control operation of the energy storage device such that the energy storage device is charged with the off-peak electricity at an off-peak time each day when a demand for electricity is low from the electricity grid, and is discharged at a peak time each day when the demand for electricity is high, to provide an amount of the stored electricity, to the at least one electricity provider, wherein the amount of the stored electricity provided to the at least one electricity provider is
W=(1−η)×Woff−Wc,wherein η is a loss rate of the stored electricity, and Wc is an amount of electricity of which the property owner consumes per day. |
