Systems and methods for stationary energy storage system optimization

An energy storage system comprising:

• an energy storage device;
• an inverter configured to control a flow of power out of the energy storage device;
• a rectifier configured to control the flow of power into the energy storage device;
• one or more controllers configured to:
• generate a schedule based on data relating to energy costs, the generated schedule indicating whether the energy storage system is to be placed in a charging state, a discharging state, or an idle state during respective periods, wherein the one or more controllers are further configured to:
• check a charge level of the energy storage device;
• determine an amount of time the energy storage device is able to be discharged based on the charge level;
• and
• generate the schedule based on the data and the amount of time the energy storage device is able to be discharged;
• and
• control the inverter and the rectifier based on the schedule.

A method of controlling an energy storage system, executing on one or more controllers, the method comprising:

• checking a charge level of an energy storage device of the energy storage system;
• determining an amount of time the energy storage device is able to be discharged based on the charge level;
• generating a schedule based on data relating to energy costs and the amount of time the energy storage device is able to be discharged, wherein the schedule indicates whether the energy storage system is to be placed in a charging state, a discharging state, or an idle state during respective periods;
• and
• controlling a flow of power to or from the energy storage device based on the schedule.

A system comprising,

• an energy storage device;
• a generator set configured to generate power to drive one or more loads, wherein one of the one or more loads is the energy storage device when the energy storage device is configured to charge;
• an inverter configured to control a flow of power out of the energy storage device;
• a rectifier configured to control the flow of power into the energy storage device;
• and
• one or more controllers configured to:
• generate a schedule based on data relating to energy costs, the generated schedule indicating whether the energy storage system is to be placed in a charging state, a discharging state, or an idle state during respective periods, wherein the one or more controllers are further configured to:
• check a charge level of the energy storage device;
• determine an amount of time the energy storage device is able to be discharged based on the charge level;
• and
• generate the schedule based on the data and the amount of time the energy storage device is able to be discharged;
• and
• control the inverter and the rectifier based on the schedule.
