Abstract
The present disclosure is directed to systems and methods for controlling an electrical system using setpoints. Some embodiments include control methods that monitor an adjusted net power associated with the electrical system and adjust the setpoint based on a comparison of the adjusted demand to the setpoint. If the adjusted demand has not exceeded the demand setpoint, the setpoint is reduced. If the adjusted demand has exceeded the demand setpoint, the setpoint is increased.
Claims31
A controller of an electrical power system, the controller comprising:
- a data storage device to store a demand setpoint representing a desired upper limit of demand of an electrical power system;
- one or more processors operably coupled to the data storage device and configured to:
- provide at least one control value to the electrical power system to effectuate a change to the electrical power system to attempt to comply with the demand setpoint;
- monitor an adjusted demand associated with the electrical power system;
- compare the adjusted demand to the demand setpoint and if the adjusted demand is greater than the demand setpoint, increase the demand setpoint;
- and
- reduce the setpoint.
An electrical power control system, comprising:
- one or more sensors coupled to an energy storage system and one or more loads of an electrical power system, the one or more sensors configured to measure power stored by the energy storage system, and demand of the electrical power system;
- a controller coupled to the one or more sensors and the energy storage system, the controller configured to:
- set a demand setpoint representing a desired upper limit of demand of the electrical power system;
- monitor the demand of the electrical power system;
- compare the demand of the electrical power system during a previous period of time to the demand setpoint;
- and
- adjust the demand setpoint for a future period of time by:
- reducing the demand setpoint;
- and
- increasing the demand setpoint when the power drawn from an electrical utility distribution system exceeds the demand setpoint during the previous period;
- and
- provide at least one control value to the electrical power system to effectuate a change to the electrical power system to attempt to comply with the adjusted demand setpoint.
A method for controlling an electrical system, the method comprising:
- monitoring an adjusted demand associated with the electrical power system;
- comparing the adjusted demand to the demand setpoint;
- decreasing the demand setpoint periodically;
- increasing the demand setpoint if the adjusted demand exceeded the demand setpoint;
- and
- providing at least one control value to the electrical power system to effectuate a change to the electrical power system to attempt to comply with the demand setpoint.
