Abstract
Systems, methods, and controllers for controlling an adjustment process for a target system are provided. A central controller receives time-related electrical energy demand data, sensor data from controllers of devices which selectively apply electrical power to the target system, and commands the controllers to apply power to exceed a target control value up to a maximum control value where the electrical energy demand data remains below a threshold and only apply sufficient energy to reach the target control value, at least within a margin, where the electrical energy demand data remains above the threshold.
Claims20
A system for controlling an adjustment process for a target system that draws power from an electrical power source, said system comprising:
- devices for controllably applying electrical power from the electrical power source to the target system to cause energy changes at the target system, each of the devices comprising a controller configured to operatively control application of the electrical power, and one or more sensors configured to supply a signal to the controller regarding an energy state of the target system;
- and
- a central controller configured to:
- receive electrical energy demand data from the electrical power source and data from the controllers regarding the energy state of the target system;
- command the controllers to draw power from the electrical source until the measured energy state of the target system exceeds, up to a maximum process control value, a process control target value while the electrical energy demand data received remains below an electrical energy demand threshold;
- and
- command the controllers to draw power from the electrical source until the measured energy state of the target system meets, at least within a predetermined margin, the process control target value while the electrical energy demand data received remains below the electrical energy demand threshold.
A method for controlling an adjustment process for a target system that draws power from an electrical power source, said method comprising:
- situating devices for controllably applying electrical power from the electrical power source to the target system to cause energy changes at the target system, wherein each of the devices comprise a controller configured to operatively control application of the electrical power, and one or more sensors configured to supply a signal to the controller regarding energy state of the target system;
- placing a central controller in communication with each of the devices;
- receiving, at the central controller, electrical energy demand data from the electrical power source and data from the controllers regarding the energy state of the target system;
- commanding, by way of the central controller, the controllers to draw power from the electrical source until the measured energy state of the target system exceeds, up to a maximum process control value, a process control target value while the electrical energy demand data received remains below an electrical energy demand threshold;
- and
- commanding, by way of the central controller, the controllers to draw power from the electrical source until the measured energy state of the target system meets, at least within a predetermined margin, the process control target value while the electrical energy demand data received remains below the electrical energy demand threshold.
