System and Method for Managing the Charging and Discharging of an Energy Storage Device
First Claim
1. A method for managing the charging and/or discharging of an energy storage device, the method comprising:
- obtaining, at a processing device, a plurality of clearing price data points spanning a plurality of dates, each clearing price data point being indicative of a clearing price of a unit of energy on a certain date;
for each date represented in the plurality of clearing price data points;
generating, at the processing device, a distribution of the clearing price data points corresponding to the date;
determining, at the processing device, a lower quantile price point of the distribution based on a capacity of the energy storage device and a charge rate of the energy storage device; and
determining, at the processing device, an upper quantile price point of the distribution based on the capacity of the energy storage device and the discharge rate of the energy storage device;
selecting, at the processing device, a first set of the lower quantile price points from the determined lower quantiles;
selecting, at the processing device, a second set of the upper quantile price points from the determined upper quantiles;
determining, at the processing device, a buy bid indicating an offered price for a purchase of energy based on the first set, wherein when the buy bid is accepted, purchased energy is delivered to and charges the energy storage device at a first prescribed time;
determining, at the processing device, a sell bid indicating an offered price for a sale of energy based on the second set, wherein when the sell bid is accepted, sold energy is discharged from the energy storage device at a second prescribed time;
transmitting the buy bid to an energy market server when the current capacity of the energy storage device is less than a maximum threshold; and
transmitting the sell bid to the energy market server when the current capacity of the energy storage device is greater than a minimum threshold.

Abstract
Techniques for managing the charging and/or discharging of an energy storage device are disclosed. The techniques include obtaining clearing price data points spanning a plurality of dates and for each date: generating a distribution of the clearing price data points corresponding to the date; determining a lower quantile price point of the distribution based on a capacity of the device and a charge rate of the device; and determining an upper quantile price point of the distribution based on the capacity and a discharge rate of the device. The techniques include selecting a first set of the lower quantile price points from the lower quantiles and a second set of the upper quantile price points from the upper quantiles. The techniques include determining a buy bid based on the first set and a sell bid based on the second set and selectively transmitting the buy bid and/or the sell bid.

13. An energy market server for managing the charging and/or discharging of an energy storage device, the server comprising:
-
a network interface device; a storage device; and a processing device configured to; obtain a plurality of clearing price data points spanning a plurality of dates, each clearing price data point being indicative of a clearing price of a unit of energy on a certain date; for each date represented in the plurality of clearing price data points; generate distribution of the clearing price data points corresponding to the date; determine a lower quantile price point of the distribution based on a capacity of the energy storage device and a charge rate of the energy storage device; and determine an upper quantile price point of the distribution based on the capacity of the energy storage device and the discharge rate of the energy storage device; select a first set of the lower quantile price points from the determined lower quantiles; select a second set of the upper quantile price points from the determined upper quantiles; determine a buy bid indicating an offered price for a purchase of energy based on the first set, wherein when the buy bid is accepted, purchased energy is delivered to and charges the energy storage device at a first prescribed time; determine a sell bid indicating an offered price for a sale of energy based on the second set, wherein when the sell bid is accepted, sold energy is discharged from the energy storage device at a second prescribed time; transmit the buy bid to an energy market server when the current capacity of the energy storage device is less than a maximum threshold; and transmit the sell bid to the energy market server when the current capacity of the energy storage device is greater than a minimum threshold. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
