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.
Claims20
A controller of an electrical power system, the controller comprising:
- a data storage device configured to store a demand setpoint representing an upper limit demand of the electrical power system;
- and
- one or more processors operably coupled to the data storage device and configured to:
- compare an adjusted demand associated with the electrical power system to the demand setpoint;
- adjust the demand setpoint, wherein the demand setpoint adjustment occurs at a frequency higher than a billing frequency associated with the electrical power system, and wherein the demand setpoint adjustment is based at least on a function of historic load data and a power level of an alternate power system;
- obtain a configuration of the electrical power system, the configuration including one or more constraints of the electrical power system and one or more cost elements including equipment degradation costs;
- based on the configuration, determine a control plan for the electrical power system, the control plan including the adjusted demand setpoint and one or more control parameters for each time segment of a set upcoming time segments;
- and
- provide, according to the control plan, at least one control value to at least one of a load and a generator of the electrical power system to effectuate change to the electrical power system toward compliance with the demand setpoint during a time segment of the set of upcoming time segments, wherein the control value is based on the one or more control parameters for the time segment.

A method comprising:
- storing a demand setpoint representing an upper limit demand threshold of an electrical power system;
- comparing an adjusted demand associated with the electrical power system to the demand setpoint;
- and
- adjusting the demand setpoint, wherein the demand setpoint adjustment occurs at a frequency higher than a billing frequency associated with the electrical power system, and wherein the demand setpoint adjustment is based at least on a function of historic load data and a power level of an alternate power system;
- and
- obtaining a configuration of the electrical power system, the configuration including one or more constraints of the electrical power system and one or more cost elements including equipment degradation costs;
- based on the configuration, determine a control plan for the electrical power system, the control plan including the adjusted demand setpoint and one or more control parameters for each time segment of a set upcoming time segments;
- and
- providing, according to the control plan, at least one control value to at least one of a load and a generator of the electrical power system to effectuate change to the electrical power system to attempt to comply with the demand setpoint during a time segment of the set of upcoming time segments, wherein the control value is based on the one or more control parameters for the time segment.
