Description

ENERGY STORE
Field of the Invention
The invention relates to systems, methods and apparatus for storing energy in a domestic or commercial environment, and in particularly energy generated from episodic renewable sources and transmitted to an energy store within the domestic or commercial environment via an electrical distribudon grid.
Baekround and Prior An Renewable sources of energy are increasingly being used to generate power. Such sources include wind, wave and tidal power and the use of photovoltaic cells to collect is solar energy. One abiding issue with such sources of cower is, however, that. the rate of generation (or effectively harvesting) of power is somewhat unpredictable and at best intermittent. It is a challenge to the power generation industry to find a way of balancing the supply of such power with consumer demand, especially in light of the difficulty and/or expense of storing electrical energy. I'he use of other more controllable power sources such as oil, gas, coal and nuclear generation to balance the supply and demand creates potential difficulties in those supply industries, especially as the power generation for a distribution grid increases it reliance on renewable sources.
It. is aniongst the object.s of the present invention to provide apparatus t.o help solve that problem.

By utilifing a series of such energy stores distributed across the grid, problems of energy storage may he at least alleviated by giving greater flexibility to balance supply with demand.
to Preferably, said apparatus further comprises a temperature sensor in operative connection with said heat store, and wherein said controller is further configured to switch power to said heater in response to a received signal only when the measured temperature in the heat. store is below a predetermined maximuni temperature. In this way, considerations of safety may he addressed, e.g. to ensure that domestic hot water is is not too hot for a user's needs.
Preferably also, said controller is further configured to determine the available thermal capacity of said heat store with reference to the measured temperature and the known thermal characteristics of said store. fly knowing thc size of the thermal store, the heat capacity, the measured temperature and the pre-set maximum temperature, the available thermal capacity may be calculated.
Preferably also, said communication unit is further configured to nnsmit a signal indicating said available thermal capacity to a remote eleetrieit.y provider. In this way, the total available energy storage capacity across a distributed grid may he calculated by the energy provider, further allowing control of the energy generation network.
Preferably also, said apparatus further comprises a user interface to allow a user to override the operation of said controller in the face of received signals.
Preferably also said apparatus further comprises a processor and a data store to store patterns of a user's energy use and/or requirements and to control heat input into said heat store so as to maintain available thermal capacity for use in response to said received signal, whilst providing sufficient stored energy to meet a user's predicted needs.
Preferably also said heater is one heater in a multi-zone heater.
In preferred enibodinients said heal store comprises a hot waLer storage tank.
In further preferred embodiments said heat store comprises a storage heater, for example a space healing unit where thermal energy is stored by healing solid storage to elements such as ceramic blocks.

Also included in the scope of the invention is apparatus substantially as described herein with reference to and as illustrated by any appropriate combination of the accompanying drawings.
Brief Description of the Figures
[he invention will be described with reference to the accompanying drawings, in a which Figure 1 shows a schematic representation of apparatus and systems of the present invention.
Description of Preferred I imbodiments
to Figure 1 is a schematic illustration of apparatus and systems of the present invention.
Illustrated is a thermal energy storage unit in the form of a domestic water tank.
Other embodiments of such a storage unit arc described herein, and thc domcstic water storage tank is used by way of example. Water connections to and fromi t.he tank are not illustrated in Figure 1 for sake of clarity.
Also shown is a limE, heater 2 in thermal communication with the energy store. In this embodiment, the system comprise three such heaters 2, 3 and 4, each in thermal communication with a separate zone of the thermal store 1.
The tank is also provided with corresponding temperature sensors 5, 6, 7 each again in thermal communication with a corresponding zone of the thermal store 1. A controller and switching apparatus 8 is provided, to control switching of the heater(s) 1-2 via signal lines 9. Signals corresponding to temperature measurements are passed to the controller 8 by means of further temperature signal lines 10.
A communication unit 11 is configured to receive and optionally to send signals 12 to and from a remotely-located electricity provider 13 (potentially via an intermediary) to allow the provider 13 to signal that they would like to store sonic generated energy in the energy store. fle contiuller can configured to respond to such a signal and thereby activate one or more of the heaters (2-4) in response to the signal.
In particularly preferred embodiments, the system also comprises a processor and dat.a store 14 that can store patterns of a user's energy usage (e.g. the usage of domestic hot water) or patterns of a user's desired energy availability (e.g. to provide hot water for showers in the morning). In this way the system may he configured to leave some thernial capacity available in Ge energy store until a short period (perhaps an hour or two) before the expected user demand in the event thai a signal 12 is received from the energy provider. For example, when the known heating time to provide the a desired capacity of stored energy (e.g. hot water) equals the time before the deadline for providing the required energy storage (e.g. when the hot waler is required by the user) this may trigger the heating of the energy store.
The controller can also be configured to deternune the available energy storage to capacity in the thermal store, and transmit a signal 12 indicative of this capacity to the energy provider. In this way the energy provider can have greater knowledge of the available energy storage across the distribution grid, and can schedule and plan operation of (he renewable energy generating systems to best. effect..
is Parameters may be set by a user (or pre-set by a manufacturer) to limit the acceptance of energy at the request of the energy provider in response to e.g. a pre-set. tiiaximum temperature of the energy store, Also, the system may be configured to allow a user to reject energy at the request of a provider, for example if the user is on holiday, and does not wish to suffer the standing losses that might occur from having a hot energy store when no energy demand (e.g. hot water demand) is anticipated for a period.
In particularly preferred embodiments, the system may he configured such that one zone of the energy store (e.g. the bottom-most zone in a multi-zone heated hot water cylinder) might he reserved for control only at the request of the external energy provider.
