Managing an energy storage system
First Claim
1. A method performed by a control system of an energy storage system, the method comprising:
- receiving one or more commands from an energy management system of an electrical grid, and in response, executing a command compliance routine to charge or discharge energy from the energy storage system to the electrical grid in accordance with the one or more commands;
and receiving one or more system condition values from the energy storage system and one or more market condition values for the electrical grid and executing a management routine to charge or discharge energy from the energy storage system to the electrical grid by comparing a first numerical value to a second numerical value, the first numerical value based on a first difference between the one or more system condition values and a first target value, and the second numerical value based on a second difference between the one or more market condition values and a second target value, wherein, in response to determining to discharge the energy storage system, executing the management routine comprises;
sending a request to the energy management system to discharge;
receiving a reply to the request from the energy management system specifying that discharging is authorized; and
discharging the energy storage system as authorized by the reply to the request.

Abstract
A system includes an energy storage system configured to supply energy to an electrical grid and a control system coupled to an energy management system of the electrical grid and configured to control the energy storage system. The control system receives one or more commands from the energy management system, and in response, executes a command compliance routine to charge or discharge energy from the energy storage system to the electric grid in accordance with the one or more commands. The control system also receives one or more system condition values from the energy storage system and one or more market condition values for the electric grid and executes a management routine to charge or discharge energy from the energy storage system to the electric grid based on the system condition values and the market condition values.
