Systems and methods for remote power management using 802.11 wireless protocols
First Claim
1. The method to control the activation of a power load comprising:
- receiving at an on-premise processor a power restriction status indicator transmitted over a distribution network from a load management host processor and storing the power restriction status indicator in a memory of the on-premise processor;
receiving a load authorization request communicated using an 802.11X-based wireless protocol transmitted from a power load controller co-located with the power load, the load authorization request received by the on-premise processor;
retrieving the power restriction status indicator data stored in the memory and determining a restriction status;
generating a response message authorizing or denying activation of the power load based on the value of the restriction status, the response message including an address associated with the power load controller; and
communicating the response message using the 802.11X-based wireless protocol from the on-premise processor to the power load controller.

Abstract
Systems and methods are disclosed for using 802.11 based wireless protocols in various energy management applications wherein a host controller uses various types of communication networks to distribute information to an on-premise processor that in turn uses 802.11 based wireless protocols to communicate with various types of end devices, such as utility meters. Various forms of communication are defined between the end device, the on-premise processor, and the energy management host for accomplishing power load control, including determining when to activate or deactivate a load, requesting permission to activate a load, reading usage data, activating or deactivating a meter, and determining rate schedules. A flexible scheme allows control to be shifted to be resident in various entities. The architecture is applicable not only for power load control, but other control type and metering devices.

1. The method to control the activation of a power load comprising:
-
receiving at an on-premise processor a power restriction status indicator transmitted over a distribution network from a load management host processor and storing the power restriction status indicator in a memory of the on-premise processor; receiving a load authorization request communicated using an 802.11X-based wireless protocol transmitted from a power load controller co-located with the power load, the load authorization request received by the on-premise processor; retrieving the power restriction status indicator data stored in the memory and determining a restriction status; generating a response message authorizing or denying activation of the power load based on the value of the restriction status, the response message including an address associated with the power load controller; and communicating the response message using the 802.11X-based wireless protocol from the on-premise processor to the power load controller. - View Dependent Claims (2, 3, 4, 5, 6)

7. A method to control activation of a power load, comprising:
-
receiving at an on-premise processor a power restriction indication communicated from a load management host using a distribution network, the power restriction indication stored in a memory of the on-premise processor; receiving at the on-premise processor a first authorization request to activate the power load communicated using an 802.11X-based wireless protocol from a power load controller controlling the power load; determining in the on-premise processor a power restriction status based on the power restriction indication data stored in the memory of the on-premise processor; communicating a first response from the on-premise processor to the power load controller using the 802.11X-based wireless protocol authorizing power load activation if the power restriction status is a first value; communicating a second authorization request from the on-premise processor to the load management host processor using the distribution network indicating an address of the on-premise processor if the power restriction status is a second value; receiving a second authorization response from the host processor at the on-premise processor using the distribution network indicating an authorization or a denial of activation of the power load; and sending a third authorization response from the on-premise processor using the 802.11X-based wireless protocol to the power load controller, the third authorization response message either authorizing activation of the power load if the second authorization response authorizes activation of the power load, or denying activation of the power load if the second authorization response denies activation of the power load. - View Dependent Claims (8, 9, 10, 11)

12. A method to control a power load comprising:
-
receiving at an on-premise processor a first authorization request message to activate a power load, the first authorization message sent from a power load controller operatively connected to the power load; sending a second authorization request message transmitted from the on-premise processor using a distribution network to a host processor indicating an address associated with the power load controller; receiving a first authorization response message at the on-premise processor transmitted using the distribution network from the host processor indicating authorization on denial of activating the power load; generating in the on-premise processor a second authorization response message indicating an authorization or denial of activating the power load; and sending the second authorization response message using the 802.11X-based wireless protocol from the on-premise processor to the power load controller. - View Dependent Claims (13, 14, 15)

16. A method to control a power load comprising:
-
sending a first notification message from a host processor to an on-premise processor indicating a request for controlling a power load; determining a first address in the memory of the on-premise processor; communicating a first power control request message using an 802.11X-based wireless protocol incorporating the first address to a power load controller associated with the first address; deactivating the power load by the power load controller in response to the power control request message; receiving a first acknowledgement message communicated using the 802.11X-based protocol from the power load controller to the on-premise processor; and receiving a second acknowledgement message at the host processor, the second acknowledgement message sent by the on-premise processor in response to receiving the first acknowledgement message. - View Dependent Claims (17, 18, 19)

20. A method to control a power load, comprising:
-
sending a first notification message of an impending power control request message to an on-premise processor from the power control host processor using an 802.11X-based protocol; receiving a first acknowledgement message at a power control host processor from the power load controller using the 802.11X-based protocol; sending a power control request message to the on-premise processor from the power control host processor using the 802.11X-based protocol requesting deactivation of the power load; receiving a second acknowledgement message from the on-premise processor acknowledging deactivation of the power load wherein the message is communicated using an 802.11X-based protocol; and recording in the power control host processor a load deactivation indication in a data structure associated with the on-premise processor. - View Dependent Claims (21, 22, 23)
