ENERGY STORAGE
First Claim
1. A method of controlling storage of electrical energy by charging and discharging an energy storage device in response to pricing data indicative of future prices of electrical energy over time and energy losses caused by charging and discharging the energy storage device, the method comprising:
- detecting alternating candidate charging and discharging occasions with respect to the pricing data by selecting a next occurrence of a locally minimum price in the pricing data as a candidate charging occasion or a next occurrence of a locally maximum price in the pricing data as a candidate discharging occasion;
validating a candidate charging or discharging occasion if the price difference between that candidate charging or discharging occasion and another later price in the pricing data is at least sufficient to compensate for the energy losses caused by charging and discharging the energy storage device; and
charging and discharging the energy storage device at the validated charging and discharging occasions, respectively.

12. An energy storage controller for controlling storage of electrical energy by charging and discharging an energy storage device, the controller being responsive to pricing data indicative of future prices of electrical energy over time and energy losses caused by charging and discharging the energy storage device, the controller comprising:
-
a detector configured to detect alternating candidate charging and discharging occasions with respect to the pricing data by selecting a next occurrence of a locally minimum price in the pricing data as a candidate charging occasion or a next occurrence of a locally maximum price in the pricing data as a candidate discharging occasion; a validator configured to validate a candidate charging or discharging occasion if the price difference between that candidate charging or discharging occasion and another later price in the pricing data is at least sufficient to compensate for the energy losses caused by charging and discharging the energy storage device; and a charge controller operable to charge and discharge the energy storage device at the validated charging and discharging occasions, respectively. - View Dependent Claims (13, 14, 15, 16, 17)
