TLDR
In this paper, a load shed module for use in a power distribution system that includes facility for delivering both electrical power and electrical power rate information from a utility supplier is presented, where a rotary switch is mounted on the enclosure, and rotary rate indicia is provided on an enclosure adjacent to the rotary switches for operator selection of a rate tier at which the socket is to be disconnected from the plug.Abstract:
A load shed module for use in a power distribution system that includes facility for delivering both electrical power and electrical power rate information from a utility supplier. The load shed module includes an enclosure having a power plug for receipt in a standard utility power outlet such as a wall socket, and a power socket on the enclosure for connection to a power load. A relay switch is disposed within the enclosure for selectively electrically connecting the plug to the socket to deliver electrical power to the load coupled to the socket. A rotary switch is mounted on the enclosure, and rotary rate indicia is provided on the enclosure adjacent to the rotary switch and coordinated with position of the rotary switch for operator selection of a rate tier at which the socket is to be disconnected from the plug. Utility power rate information is received from the utility supplier and compared with the rate tier selected by the operator at the rotary switch. When the power rate information equals or exceeds the selected rate tier, the module socket is disconnected from the plug so that the associated load is effectively disconnected from the power distribution system.read more

Engery management and building automation system
TL;DR: In this paper, a CEBus-based energy management and building automation system including a local area network or home automation data bus such as the CEBus is described. But the second microcomputer serves as an input/output terminal, allowing the customer to set parameters and query the system as to power usage, displaying reports requested by the customer and messages transmitted by the utility company and by either microcomputer.

Apparatus and method for controlling an electrical load and monitoring control operations and the electrical load
Glenn A. Davis,James M. Massara +1 more
TL;DR: In this paper, a controller for controlling an electrical load in an electrical distribution network in response to command signals transmitted by a command center remotely located from the electrical load is presented. But the controller does not have the ability to monitor the load control operations and the energy supplied to the electrical loads.

Responding to pricing signals from a power supplier using mixed add/shed and profile setback delta schemes
TL;DR: In this paper, a method for employing utility-supplied information relies on two schemes for accommodating such pricing information: direct load control and user overrides are allowed; where appropriate, a setback is applied across subsystems that operate on setpoints, and other loads are add/shed based on their value vis-a-vis interpreted utility pricing information signals.
