Description

ENERGY MANAGEMENT SYSTEM AND METHOD OF USE THEREOF
This invention relates to an energy management system and to a method of use thereof.
Conventionally, an energy supply company will purchase energy, such as electricity and gas, in a wholesale market and sell it on to customers. A large proportion of the energy is purchased weeks, months or even years in advance of when it is to be used so that the best price for the energy can be obtained on the wholesale market. In addition, it allows the energy comp ny to guarantee the supply of energy to their customers. This type of purchasing is known as hedging and helps to even out the costs associated with energy purchase over time. However, a disadvantage of advance energy purchasing is that the energy supply company does not know what the actual customer energy requirements will be on any particular day in the future. As such, the energy supply company has to estimate how much energy is required. This estimate is difficult to undertake accurately so far in advance as the company may not have details relating to future weather conditions, what appliances a customer may be using in their home, whether any public or sporting events may be scheduled (it is often found that energy requirements increase when an important football match is being televised for example) and/or the like. On a particular day, any shortfall in energy previously purchased has to be topped up by purchasing energy on the day. Any excess energy purchased, is typically sold. However, it will be appreciated that energy purchased on the day is likely to be subject to higher prices than energy purchased months in advance. It is therefore an aim of energy supply companies to be able to more accurately predict the energy consumption of their customers.
In an attempt to address this problem, it is known to provide a smart meter in an energy consumer's home that records the consumption of electrical energy used within the home over a period of time. The smart meter allows two way communication of data between the energy consumer and the energy supply company for the purposes of monitoring energy consumption and billing. However, this data typically relates to the property as a whole and it cannot distinguish between individual energy consuming devices within the home or property. In addition, the data generated by the smart meter only relates to energy that has been consumed. Although the data collected by the smart meter may be helpful to the energy supply company in being able to estimate how much energy a property or home may require on average in the future, it does not allow accurate monitoring of the energy supply requirements of the property or home on a real time basis or over a relatively short future time period, such as hours or days.
It is therefore an aim of the present invention to provide an energy management system that overcomes the abovementioned problems.
It is a further aim of the present invention to provide a method of using an energy management system that overcomes the abovementioned problems.

Figure 4 is an example of an interface provided on an energy supply control server; Figure 5 is further example of an interface provided on an energy supply control server showing an individual customer's electricity usage over a pre-determined time period;
Figure 6 is an example of an interface that could be provided on the common control unit shown in figure 2.
Referring firstly to figure 1, there is illustrated an energy management system 2 according to an embodiment of the present invention. The energy management system 2 comprises an energy consuming device 6 that consumes energy when in at least an operational condition. It is to be noted that the device 6 could also consume some energy when in a non-operational condition, albeit significantly less than when in an operational condition, such as for example, in a standby condition. Alternatively, the device 6 may consume no energy when in a non-operational condition. In one example the energy consuming device 6 is in the form of an electrical heater and is located at a first location.
The energy management system further comprises an energy supply source 8, such as for example an electricity sub-station, which takes electricity from a power station and transports it to device 6 at the first location along electricity cables 10 provided between the sub-station 8 and the device 6. The electricity source 8 is at a second location remote to the first location.
The energy management system also comprises energy supply control means in the form of a energy supply control server 4 located at an energy supply company at a third location. The first and second locations are typically remote from the third location. The energy supply control server 4 is arranged to purchase electricity from an electricity wholesale marketplace, such as for example, an electricity stock exchange and/or the like. This purchase is typically undertaken following a request for electricity submitted from the device 6.
The energy consuming device 6 has control means in the form of a control unit 12 provided on the same. Transceiver devices 14, 16 are associated with the control unit 12 at the first location and the energy supply control server 4 located at the third location respectively. These transceiver devices 14,16 allow two way cornmunication between the device 6 and the server 4 in use. In the illustration, communication between the transceiver devices 14, 16 is typically wireless, such as via WIFI, but it will be appreciated that other forms of wireless or wired technology could be used.
The control unit 12 contains a micro-processor and data storage to allow historical energy usage data to be stored and/or data relating to one or more parameters. The control unit includes one or more sensors for sensing some of the one or more parameters. The one or more parameters can include any or any combination of one or more of the prevailing weather conditions at the first location, the future weather forecast or conditions for the first location, current energy usage of device 6, historical usage of device 6, one or more scheduled events, such as football matches, popular events that may influence whether device 6 is operational and/ or the like, the detection of one or more animals and/or humans in the vicinity of device 6, movement detection in the vicinity of device 6, room temperature or ambient temperature in the room or vicinity of device 6, voltage usage of device 6, amp usage of device 6, wattage usage of device 6, current time, target temperature for the room or vicinity in which device 6 is located and/or for device 6, device 6 surface temperature and/or the like.
The control unit 12 is able to calculate an amount of energy it is currently using in real time and also predicts the amount of energy it will need for an imminent time period in the future, such as for example the next 4 hours, based on the data collected and/or stored relating to the one or more parameters. The control unit 12 can perform this prediction based on mathematical formulae, algorithms, software and/or the like. The control unit 12 then communicates this predicted energy data request, typically together with data relating to the current/real time energy usage for device 6 to the energy supply control server 4. The energy supply control server 4 is then able to use this transmitted energy data to purchase the predicted amount of energy at that point in time and also to bill the customer associated with device 6 for the amount of energy purchased. This method is a significantly more accurate method of purchasing energy, thereby preventing the problems of over-purchasing or under-purchasing of energy associated with the prior art. To prevent under purchasing the energy supply control server 4 can also instruct a device 6 to limit it's electrical usage to make sure that under purchasing is eliminated. In one embodiment device 6 can be an infrared heater and turning that off for short time periods will have little detriment to the temperature in a room in which the infrared heater is located but will reduce the amount of energy consumed by the device.
The energy management system 100 shown in figure 2 works in a similar manner to the energy management system 2 shown in figure 1, with the exception that a plurality of energy consuming devices 6, 6', 6" are provided in a house 102 at the first location. Each energy consuming device 6, 6', 6" has a control unit 12 and a transceiver 14. The electricity required to power devices 6, 6', 6" enters the house 102 via electricity cable 10 provided between the sub-station 8 and the house. Once the electricity reaches house 102, it then travels along electricity cables 104, 106, 108 to the respective devices 6, 6', 6". A common control unit 110 is provided in house 102 which also has a transceiver 112. The common control unit 110 can communicate directly and independently with each of devices 6, 6', 6" and also with energy supply control server 4. Thus, in this embodiment devices 6, 6', 6" do not generally communicate directly with energy supply control server 4 but communicate indirectly via common control unit 110. Communication between common control unit 100, energy supply control server 4 and control unit 12 is typically wirelessly as before, but could be wired communication and/or a combination of wired and wireless communication as required.
Figure 3 illustrates an example of an energy consuming device 6 in the form of an infra-red wall mounted heater. Figure 4 illustrates an example of an interface 200 provided on a display screen associated with the energy supply control server 4. The interface 200 is arranged to display a number of data items, such as a customer identification number 202 to identify the customer's energy usage. Other data items displayed can include data relating to the actual recorded energy usage in kWh supplied by common control unit 110 provided in column 204 of table 206; data relating to the predicted energy usage in kWh supplied by common control unit 110 provided in column 208 of table 206; the cost of the energy purchased is provided in column 210 and time on an hour by hour basis within a 24 hour time period is shown in column 212. This data is represented graphically in graph 214 provided on interface 200.
Figure 5 illustrates a further example of data that can be displayed on interface 200.
