• Figure 4 is a diagram describing the flow of activities relating to an implementation of the solution according to an embodiment of the invention.
• the system 100 has a client/server architecture, wherein servers 105 (only one shown in the figure) manage a plurality of clients 110. Multiple clients 110 are connected to server 105 (for example, clients 110 can be coupled to household or electronics appliances, e.g. washing machine, DVD recorders, computers) .
• the server 105 and the clients 110 communicate through a network which allows to communicate the intention to turn on the appliance/switch associated to a given client; typically, the network 115 is implemented by means of a medium which is able to carry electronic control signals, for example by means of conveyed waves, which is a common method to propagate low voltage control signals over regular electrical wires (e.g.
• the server 105 consists of a computer being formed by several units that are connected in parallel to a system bus 120.
• one or more microprocessors (//P) 125 control operation of the server 105;
• a RAM 130 is directly used as a working memory by the microprocessors 125, and
• a ROM 135 stores basic code for a bootstrap of the server 105.
• Several peripheral units are clustered around a local bus 140 (by means of respective interfaces) .
• a mass memory consists of one or more hard-disks 145.
• the server 105 includes input units 160 (for example, a keyboard), and output units 165 (for example, a monitor) .
• An adapter 170 is used to connect the server 105 to the network 115.
• a bridge unit 175 interfaces the system bus 120 with the local bus 140.
• Each microprocessor 125 and the bridge unit 175 can operate as master agents requesting an access to the system bus 120 for transmitting information.
• An arbiter 180 manages the granting of the access with mutual exclusion to the system bus 120.
• server 105 is connected to the meter 201 and to a plurality of agents 110.
• this device 105 provides a new functionality which can range from a mere alerting service to a proper control and management of the electricity consumption within the house.
• PED power enabler device
• PED could be located anywhere between the main meter/switch, normally provided by the electrical distribution company, and the household appliances or, more in general, the electrical devices to be managed. Its preferred location is however inside the apartment itself, near the remainder of the main internal switches (normally used to section the electrical network between e.g. 10 and 16 A loads) .
• Connected to the PED 105 there are several clients which are associated to one or more switch or plug. The amount of logic of these clients may vary to a great extent and the services provided by such clients are strictly dependent on such logic.
• the role of the PED is to give consensus, whenever a new appliance is being turned on.
• Switch which is only able to communicate its ID
• Switch which is able to communicate its ID and receive a consensus signal
• each internal switch located in the house (for either turning on lights or enabling a wall socket) , is able to transmit over the wire a unique signal ID (e.g. unique deviation out of a base CW frequency, or a unique resistance) each time it's turned on (or pressed) .
• a unique signal ID e.g. unique deviation out of a base CW frequency, or a unique resistance
• PED receives all these signal IDs from switches being turned on, and have a static table where, for each switch ID, it lists the associated known load. As PED also includes a power meter, so it's instantly aware of the current total load in use, it's able to forecast if, giving power to the wire from which the specific switch is connected, the total power threshold would be violated, and in this case it won't activate the specific wiring, that connects PED to the specific switch. In this scenario, every switch (for which a sensible load is known to be possibly connected) must have a direct wiring which connects it to the PED; such wire is usually not powered (it only allows ID signal exchange) and gets powered with 220/110 voltage, only if consensus is given from PED.
• PED In case of switches which are powered from intermediate junctions, and that have no direct wiring with the master-PED, slave PEDs could be added in the intermediate junctions. In this scenario, PED must know how much electrical power a switch will absorb, and this information can be statically defined in PED configuration, although it could optionally be self updated as consensus is given (usage statistics) , with an optional time-based reset policy.
• Wall outlets could be thought with a similar RF identification, although, as different appliance may be connected to the same outlet, the configuration should be done a priori.
• a limitation of this scenario is the static load pre-configuration, and the need to direct PED-switch wires, or of intermediate PEDs.
• the advantage is the limited logic needed in the switch.
• activity 1 indicates the request from the end-user of an electrical load activation e.g. by pressing the Sender-Switch.
• activity 2 the Sender/Switch sends a control command to the central PED server, through which it communicates its unique ID.
• each switch is not only able to send an ID signal to the PED, but is also able to receive a consensus signal, over the wire.
• activity 1 represents End user request of an electrical load activation pressing the Sender-Switch.
• activity 2 Sender-Switch sends a control command to the central PED server, through which it communicates its unique ID.
• Switch remains listening for ack/nack.
• Activity 5 Switch receives consensus control signal from PED, and in turn the Switch, working in relais mode, activates power connection to the load (activity 6) .
• each internal switch in addition to be able to send its ID (sender) and to receive a consensus signal from PED (CW receiver) , is also able to remember the last required load from the served appliance.
• the amount of power required from each switch/load may not be known a priori from PED, but switches are able to remember last used load.
• PED in this case, must only reply to the given switch ID which made the request, that the requested amount of load is available, as it won't exceed the total available load.
• ⁇ ID> and ⁇ needed power> are communicated from the switch to the PED, and there is no more need of a lookup on a static table (activity 3 of Figures 3a and 3b) . Also it's possible to have some manual control on the switch itself (500W, IkW, 2kW, etc) in case it's serving nomadic appliances, through a controlled wall outlet.
• FIG. 4 the logic flow of an exemplary process that can be implemented in the above-described system to manage the power load (or overload) within a plurality of house appliances is represented with a method 400.
• the method begins at start block 401 and passes to block 403 where the total system power usage is monitored by the PED.
• a communication from a switch, controlling its electrical load is received by the PED 105 from one of the clients 110 (step 405) .
• the expected new requested load is estimated by the system (step 407), e.g. by means of a look-up table by the PED or directly communicated by the client 110.
• step 409 If the addition of the expected new requested load to the current one does not exceed the predetermined maximum allowed power of the meter/switch 201 (step 409) then authorisation is given to the client 110 and supply of power is granted (step 411) , otherwise alternative recovery solution is implemented (step 413); in this case the request is suspended but the rest of the system does not suffer of any breakdown as with prior art systems.
• the range of possible recovery solutions is very broad and could be a simple communication to the client (and finally to the user) that the new request is not receivable (e.g. by means of an alarm) or a more complex management of the power load depending on the logic contained in the clients 110.
• the control messages exchanged between the PED Server and the plurality of clients 110 can be of several different types, depending on the level of complexity of each client. If the client 110 is only able to send its unique identity, then the PED will need to directly control the electrical power which has to be granted to the client switch, as the client is not able to receive a consensus signal; this has implications in the electrical wiring, as star-wiring form PED to client would be need (as described for scenario A above) . On the other hand, if the client is also able to receive a consensus control signal (e.g.
• client 110 may also be able to communicate additional attributes of the controlling load, so that it could be able e.g. to report the expected load demand, according to current load settings or last/historical power demand for the controlling load; this information allows PED to operate in a more dynamic way, without the need of manual power-usage settings for the different controlling client loads (see above described scenario C) .
• more complex recovery actions could be implemented, e.g. one of the currently connected appliances or devices could be disconnected to allow the new request to be satisfied, according to a predefined priority list.
• monitoring step 403 could be done only when needed, i.e. when the request at step 405 is received by the PED.
• monitoring step 403 could be done only when needed, i.e. when the request at step 405 is received by the PED.

• the proposed solution lends itself to be applied to scenarios in which clients 110 are able to report additional information to the controlling PED which could be taken into account when taking the decision; this may include load priority, for possible pre-emption of different active loads, introspection of load setting etc. It may also be possible to extend the solution to different environments, e.g. to implement a control of a whole building or using different communication means among clients and PED.
