Method of demand side electrical load management and an associated apparatus and system
First Claim
1. An apparatus for demand side electrical load management, the apparatus including a communication arrangement operable to receive messages from a remote site and a display arrangement operable to display information, characterised in that:
- the communication arrangement is operable to receive from a remote site an indication message indicative of an instantaneous electricity consumption, the display arrangement being operable to display visually the instantaneous electricity consumption;
the communication arrangement is further operable to receive from the remote site a threshold message including an indication of an electricity consumption threshold and an indication of a time period within which the consumer must limit his or her electricity consumption to comply with the electricity consumption threshold;
the display arrangement is operable to display a time remaining within which the consumer must limit his/her electricity consumption, andthe apparatus further including an acoustic transducer operable to emit an audible beeping alert indicative of receipt of the threshold message, a frequency of the beeping alert being dependent on a difference between current electricity consumption and the consumption threshold.

Abstract
The present disclosure discloses a method (310, 330, 350, 370) of demand side electrical load management and an associated apparatus (104) and system (100). The method (310, 330, 350, 370) includes providing (336, 318) a consumer of electricity with an indication of instantaneous electricity consumption. The method (310, 330, 350, 370) further includes determining (382) an electricity consumption threshold for the consumer, in response to a determination that load limiting is required and providing (384, 356, 338, 320, 322) the consumer with an indication of the electricity consumption threshold and an indication of a time period within which the consumer must limit his/her electricity consumption to comply with the electricity consumption threshold. The method (310, 330, 350, 370) also includes interrupting (360, 340, 342, 324) supply of electricity to the consumer in response to the electricity consumption of the consumer violating the electricity consumption threshold after the time period has elapsed.

5. A remote controller for demand side electrical load management, the remote controller including:
-
a plurality of electrical connections respectively for supplying electricity to a plurality of remote loads; a plurality of electrical switches respectively associated with the electrical connections; at least one electricity measurement device for measuring electricity supplied to or consumed by each of the loads; and a communication arrangement operable to; send an indication message both to a master controller, the indication message indicative of the electricity supplied to or consumed by the loads, and to a remote apparatus for demand side electrical load management, for display on the apparatus of an instantaneous electricity consumption; and receive from the master controller an interrupt message indicating electricity supply is to be interrupted to at least one of the loads; the remote controller being operable to toggle the switch, in response to receipt of the interrupt message, thereby remotely to interrupt supply of electricity to the at least one load, and the remote controller further being operable to interrupt electricity supply temporarily to a particular electrical connection and thereafter to receive an initialisation message from the remote apparatus confirming the electricity supply was interrupted, thereby to confirm that the remote apparatus is indeed associated with the particular electrical connection. - View Dependent Claims (6)

7. A master controller for demand side electrical load management, the master controller including:
-
a communication arrangement operable to; receive from a remote controller at a remote site an indication message, the indication message indicative of the electricity supplied to or consumed by each of a plurality of loads, which, in turn, is remote from the remote controller; send to the remote controller an interrupt message indicating electricity supply is to be interrupted to at least one of the loads; and an energy balancing module which is operable to measure a total amount of electricity supplied to the remote sites and which is operable to compare the total amount of actual supplied electricity against the reported electricity supplied to each of the loads as indicated in the indication messages, thereby to determine whether or not all supplied electricity is accounted for. - View Dependent Claims (8)

9. A system for demand side electrical load management, the system including:
-
a plurality of apparatus for demand side electrical load management, the apparatus including a communication arrangement operable to receive messages from a remote site and a display arrangement operable to display information, characterised in that; the communication arrangement is operable to receive from a remote site an indication message indicative of an instantaneous electricity consumption, the display arrangement being operable to display visually the instantaneous electricity consumption; the communication arrangement is further operable to receive from the remote site a threshold message including an indication of an electricity consumption threshold and an indication of a time period within which the consumer must limit his/her electricity consumption to comply with the electricity consumption threshold; and the display arrangement is operable to display a time remaining within which the consumer must limit his/her electricity consumption; at least one remote controller for demand side electrical load management, in communication with the apparatus, the remote controller including; a plurality of electrical connections respectively for supplying electricity to a plurality of remote loads; a plurality of electrical switches respectively associated with the electrical connections; at least one electricity measurement device for measuring electricity supplied to or consumed by each of the loads; and a communication arrangement operable to; send an indication message both to a master controller, the indication message indicative of the electricity supplied to or consumed by the loads, and to a remote apparatus for demand side electrical load management, for display on the apparatus of an instantaneous electricity consumption; and receive from the master controller an interrupt message indicating electricity supply is to be interrupted to at least one of the loads; the remote controller being operable to toggle the switch, in response to receipt of the interrupt message, thereby remotely to interrupt supply of electricity to the at least one load; at least one master controller for demand side electrical load management, in communication with the remote controller, the master controller including; a communication arrangement operable to; receive from a remote controller at a remote site an indication message, the indication message indicative of the electricity supplied to or consumed by each of a plurality of loads, which, in turn, is remote from the remote controller; and send to the remote controller an interrupt message indicating electricity supply is to be interrupted to at least one of the loads; and at least one computer server for demand side electrical load management, in communication with the master controller, the computer server including; a communication arrangement for receiving a plurality of indication messages respectively from a plurality of remote controllers, the indication messages being indicative of electricity supplied to or consumed by respective loads of the respective remote controllers; and a control module operable to calculate, in response to a determination that there is insufficient supply of electricity to satisfy the consumption of each of the loads, an electricity consumption threshold for which there is sufficient supply; the communication arrangement further being operable to send a threshold message to at least one of the remote controllers, the threshold message indicative of an electricity consumption threshold below which there is sufficient supply and thereafter to send an interrupt message to at least one of the remote controllers in response to a determination that at least one of the loads of that remote controller is violating the electricity consumption threshold. - View Dependent Claims (10)
