[0003] Description

[0004] Energy distribution

[0005] The invention relates to methods, devices, computer programs and computer-readable data carriers for distributing energy or power.

[0006] The availability of grid-based energy for heating and / or cooling rooms, apartments, or industrial buildings can vary. Grid-based energy distribution transmits energy, for example in the form of gas, district heating, or electricity, via pipes or cables directly to the consumer, who consumes the supplied energy immediately. To date, energy distribution has been designed in such a way that fluctuations in energy consumption by the consumer can be absorbed by storage, and sufficient energy quantities are always available to prevent undersupply.

[0007] However, an undersupply of energy or power can cause significant damage to both end users and industry, as the current energy distribution can only react to fluctuations by switching off, for example, large consumers.

[0008] Therefore, the object of the present invention is to provide methods, devices, computer programs and computer-readable data carriers that can prevent damage caused by fluctuations in the required energy or power.

[0009] This object is achieved by the independent claims. Further developments of the invention can be found in the dependent claims.

[0010] The invention relates to a method for distributing energy or power for at least two consumers who use the energy or power to heat or cool a respective room, comprising the following steps: a) providing a temperature profile, a tolerance profile and a room profile for the respective room; b) determining a current room temperature of the respective room; c) determining an available energy or power from at least one energy supplier for several future time periods; d) determining a thermal energy or power required for each consumer for the several future time periods, taking into account the current room temperatures, the temperature profiles, the tolerance profiles, the room profiles and the available energy or power;e) determining a control signal for each consumer based on the respective required thermal energy or power, whereby the respective control signal controls a supply of thermal energy or power by the respective consumer;

[0011] The invention is based on the fundamental idea that the available energy can be allocated to different consumers or rooms based on predefined profiles and the room temperature, depending on the situation, in order to avoid undesirable undersupply. Alternatively, instead of allocating energy, the invention can distribute power in an analogous manner. While the description focuses on the distribution of energy or energy quantities, the description is analogously applicable and implementable for the allocation of power.

[0012] In this description, the terms "energy" and "energy quantity" are used synonymously - unless explicitly stated. Energy is measured in kWh (kilowatt hours), which can be consumed or supplied over a period of time. The term "power" is used analogously, for example, in kW (kilowatts). Over a period of time, an energy quantity can be determined by multiplying the power by the period. The units kWh and kW are also used to describe energy or power for various energy sources, such as electricity, gas, or district heating.

[0013] Furthermore, the invention is explained in several places in the description with reference to the supply of heat. It goes without saying that the description applies analogously to the supply of cold, even if not explicitly mentioned. Cold supply can be understood here as the supply of heat, whereby the heat required to cool the room is lower than the room temperature.

[0014] In addition, within the scope of this description, room temperatures are determined which are to be achieved by supplying heat or cooling. A specialist will be aware that specifications for reaching a room temperature are associated with latency periods and that the control of room temperatures is therefore subject to temporal inertia. This means that room temperatures can also be reached with a delay when determining the energy distribution. The term consumer is understood to be a unit which converts supplied energy, such as electricity or hot water generated from natural gas by a gas boiler, into heat or cold. This unit can be implemented as a radiator, underfloor heating, air conditioning or even a heating element. The unit heats or cools the air in a room directly or indirectly.

[0015] The term room describes an enclosure, such as a living space enclosed by walls, doors, windows, floor and ceiling, or a container that holds liquids, such as a stainless steel container used in the chemical industry or in the production of food.

[0016] The expression "which uses energy or power to heat or cool a particular room" is intended to encompass, on the one hand, that the energy or power is used directly by the consumer for cooling or heating, as is the case with electricity, for example. On the other hand, it is also intended to encompass indirect use, in which the energy or power is converted from one form of energy into another over a period of time and the consumer then uses the other form of energy for heating or cooling. For example, a gas boiler uses supplied gas to heat heating water, which is then piped to the consumer and used by the consumer at the consumer's location to heat or cool the room, for example through a pipe laid in the floor.

[0017] To control the consumer, i.e., the amount of energy or power used for heating or cooling, the consumer also has a control unit with which consumption can be regulated. In the case of a radiator, this could be a radio-controlled thermostat that opens or closes a valve on the radiator to regulate the amount of energy or power supplied.

[0018] The temperature profile describes a desired room temperature. This can be a fixed room temperature or a room temperature that changes over time. Typically, different room temperatures can also be specified for each day of the week.

[0019] The tolerance profile describes a deviation from the room temperature specified by the temperature profile. For example, the tolerance profile can indicate that a room temperature deviation of, for example, + / -1 °C is tolerable. The tolerance profile can also specify different room temperature deviations over time and / or per day of the week. The deviations can be specified as discrete values, percentages of the desired room temperature, or as a function over time. Furthermore, the tolerance profile can also include acceptance values ​​that indicate whether a deviation is more or less acceptable.

[0020] The room profile describes the thermal behavior of the room. For example, it can specify how quickly the room cools down at a predefined outside temperature or how quickly the room warms up when heat is supplied by the consumer. The outside temperature is, for example, the temperature adjacent to the walls, such as outside or in a neighboring room. The room profile can include a variety of functions that describe the room temperature over time at predefined outside temperatures or the amount of energy supplied or the power output. In addition, the room profile can also provide detailed information about the room envelope, such as a specific thermal conductivity coefficient, or the size of a wall or window area and the wall thickness. With this detailed information, the energy distribution can be calculated more precisely.Storage effects and inertia effects of room properties such as walls or ceilings or solar gains through windows can also be part of the room profile, which influence the temperature behavior of the room temperature.

[0021] To determine the current room temperature of a given room, a thermometer installed in the room or integrated into a digital thermostat can display the current temperature at regular intervals, for example, every 5 minutes. Alternatively, the current room temperature can be estimated based on the amount of energy or power supplied to the room, the condition of the room's envelope, and the temperature outside the room (=outside temperature). This can be achieved using a digital twin of the room.

[0022] The available energy or power from at least one energy supplier for several future time periods indicates which energy quantities can be supplied in the future from a current perspective. For example, the first energy supplier can state that it can supply 1.5 MWh with a maximum power of 1.5 MW from 7:00 p.m. to 8:00 p.m. and 0.75 MWh with a maximum power of 1.0 MW from 8:00 p.m. to 9:00 p.m. From this, it can be deduced whether sufficient energy can be provided based on the temperature profiles or whether deviations from the temperature profile must be made due to the temperature, tolerance and room profiles. The available energy or power can be announced for a few minutes, for hours or for a few days.If a supply bottleneck is foreseeable for one energy source, this bottleneck can under certain circumstances be compensated by other energy sources, provided there is sufficient energy from the other energy source. For example, there is a 5GWh shortfall in district heating in an initial period. Since a surplus of electrical energy or power is expected in this period, the missing energy or power can be made up by supplementing the district heating with electricity. This means that there is no undersupply of district heating as an energy source. Thus, an undersupply of consumers can be avoided by energy quantity planning based on the available energy or power from the energy supplier. In general, an energy supplier is a technical unit that provides energy, for example in the form of district heating, gas or electricity.The energy supplier can be a gas storage facility, a combined heat and power plant, a wind turbine or a geothermal plant.

[0023] In addition, if multiple energy suppliers are involved, prioritization of energy suppliers can also take place, for example, depending on the amount of CO2 generated during the production of 1 kWh. The process can prioritize those energy suppliers that generate no or low amounts of CO2 per 1 kWh. A shortage can also arise if the process only purchases energy from those energy suppliers whose energy production per kWh remains below a specified CO2 amount (threshold). Thus, the process also offers the advantage that CO2 quantities can be saved or reduced through active distribution of energy or power.

[0024] The process determines the thermal energy or power required for each consumer for several future time periods, taking into account the current room temperatures, temperature profiles, tolerance profiles, room profiles, and the available energy or power. If sufficient energy or power is available, the respective room temperature can be achieved according to the associated temperature profile. If insufficient energy is available, deviations from the room temperature required by the temperature profile will occur. The tolerance profiles specify the limits up to which a reduction in the respective room temperature is tolerated.

[0025] Optimization methods can be used to determine the achievable room temperatures, for example, allowing an absolute or relative deviation of the room temperature to the same value for all consumers. Alternatively or additionally, the room temperature values ​​can be determined based on the acceptance values ​​assigned to the tolerance profiles in such a way that the respective deviation in the room temperature achieves an identical or similar acceptance value in all rooms. This has the advantage that the room temperature can deviate from the temperature profile to varying degrees because, for example, a greater deviation is accepted in bedrooms than in bathrooms. Thus, the acceptance value can be used to specify a technical parameter for an individual temperature deviation for each room and to evaluate it automatically.

[0026] Furthermore, storage effects and inertia effects can also be used to determine the thermal energy or power required for each consumer. The walls of a living space store heat and can release it. Thus, a prediction of how a room will cool down or heat up can be used to bridge short-term energy shortages. In the event of a brief interruption in the heat supply, the room temperature specified by the temperature profile can be maintained for a period of time within the deviation specified by the tolerance profile.

[0027] Based on the thermal energy or power required by each consumer, a respective control signal is determined, which enables the respective consumer to supply the thermal energy or power. With an electrically operated consumer, the electrical heating power consumed can be varied by modulation depending on the control signal. With a radiator, the control signal can precede a valve opening, for example with a value of 0% for closed to 100% for fully open. To release the determined thermal energy, the valve opening value is then adjusted so that the room temperature is reached after a latency period. During thermal balancing, volume flows and temperature increases are coordinated, whereby a temperature increase of 2° K (K-Kelvin) per hour is often a typical value.Thus, the values ​​specified by the temperature profiles and tolerance profiles are to be understood in such a way that they can be achieved after typical latency periods, such as 2° K temperature rise per hour.

[0028] In a further development of the invention, the tolerance profile is specified by at least one of the following parameters:

[0029] - Minimum room temperature

[0030] - Maximum room temperature

[0031] - Temperature deviation during absence

[0032] - Prioritization when applying deviations from the temperature profile. This means that when allocating the available energy or power to each room, the limits specified for each consumer, such as the minimum or maximum room temperature, can be individually taken into account. This simplifies the distribution of energy or power for at least two consumers, as individual deviations can be taken into account in the distribution calculation during the step “Determining the thermal energy or power required for each consumer”. Prioritization when applying deviations from the room temperature profile indicates that if there is insufficient energy or power available, the room temperature of the room with the highest priority should be reduced first so that the respective room temperature of one or more rooms, each with a lower priority, can reach the target temperature specified by the temperature profile.Prioritization can be achieved using absolute values, for example from 1-10, where 1 represents the highest priority and 10 the lowest priority.

[0033] Additionally, one or more acceptance values ​​can be added to the tolerance profile, indicating which deviations from the temperature value specified by the temperature profile are acceptable. This advantageously allows, when insufficient energy or power is available, the energy or power to be distributed in such a way that almost all consumers can achieve an optimal room temperature according to their respective acceptance values. This avoids situations in which rooms are cooled too much and other rooms are kept too hot unnecessarily.

[0034] In an advantageous further development, the spatial profile can be realized by at least one of the following parameters:

[0035] - cooling coefficient of the room;

[0036] - Construction of the room;

[0037] - Consumer performance;

[0038] - heat capacity of the room;

[0039] - Size and / or window areas.

[0040] This further development allows a future room temperature to be predicted more accurately after the supply of energy or power. In addition, the future room temperature can also be predicted more accurately if a reduced amount of heat or no heat is supplied to the room via the consumer. The cooling coefficient of the room indicates how quickly the room temperature adjusts to the outside temperature. Typically, this adjustment takes place more quickly in the room's poorly insulated walls than in well-insulated ones. The construction of the room indicates how well walls, particularly those that form an external wall of a building, release heat to the outside. The construction of a wall can be specified as a binary value with well insulated / not well insulated or as the thermal transmittance of the wall. The power of the consumer, for example in watts W, indicates how much energy the consumer can release per unit of time.Typical values ​​for radiators are 500-2000 W. The heat capacity of a room indicates how much heat the room can store and, if applicable, how much heat can be released into the room over time. For example, solid walls made of clay bricks or sand-lime bricks can store and release heat. Window areas can also influence the thermal behavior of a room, for example through solar gains or, if the walls are poorly insulated, through high temperature losses. The orientation of window areas indicates the direction the windows face. For example, a south-facing window can bring more solar gains in the form of heat into the room than a north-facing window.

[0041] In an advantageous development of the invention, the space can be designed as a room in an apartment, as an apartment with several sub-rooms, or as a container, in particular as a buffer storage tank or domestic water storage tank. The generic representation of the space makes it possible for the distribution of energy to include residential buildings as well as industrial plants. The invention thus advantageously ensures that a central heat distribution unit can take into account a large number of thermal energy consumers and distribute the energy in an optimal manner. In addition, the space can also describe a zone in a building, wherein the zone has one or more (office) rooms, which generally have a room temperature control system.

[0042] One or more steps of the method can be implemented and realized as a computer-implemented method.

[0043] The invention further comprises a distribution device for distributing energy or power for at least two consumers who use the energy or power to heat and / or cool a respective room, comprising the following units: a) provision unit for providing a temperature profile, a tolerance profile and a room profile for the respective room and b) determination unit for determining a current temperature of the respective room and for determining an available energy from at least one energy supplier for several future time periods; c) calculation unit for determining a thermal energy or power required for each consumer for the several future time periods, taking into account the current room temperatures, the temperature profiles, the tolerance profiles, the room profiles and the available energy;d) Control unit for determining a control signal for each consumer based on the respective required thermal energy or power, whereby the respective control signal controls a supply of thermal energy or power by the respective consumer; e) Transmitter unit for transmitting the control signal to the respective consumer, with which the consumer controls an amount of energy or power for heating or cooling the room.

[0044] Furthermore, the distribution device can have an execution unit which is designed such that it can implement and execute at least one of the above method steps.

[0045] This allows the distribution device to realize the same functions and have the same advantages as the process.

[0046] The distribution device, with its provision unit, determination unit, calculation unit, control unit, and transmission unit, can be implemented, realized, and executed in software, hardware, or a combination of software and hardware. Using a processor, a memory, and input and output modules connected to each other via data lines, the distribution device and its units can read individual steps of the method from the memory as machine-readable code and process them in the processor. The input and output modules are used for communication with other units, such as a respective consumer.

[0047] The invention further comprises a computer program product comprising instructions which, when the program is executed by a computer, cause the computer to carry out the method according to the above method steps.

[0048] Finally, the invention comprises a computer-readable data carrier on which the computer program product is stored. The invention and its further developments are explained in more detail below with reference to the figures. In detail:

[0049] Figure 1: Embodiment with a distribution device

[0050] Figure 2: Flowchart with individual processing steps

[0051] Elements with the same function and mode of operation are provided with the same reference numerals in the figures. The following exemplary embodiments describe the invention using energy distribution. The exemplary embodiments can be applied analogously to the distribution of power and thus also apply to power.

[0052] Figure 1 shows a first embodiment of the invention. In a first room R1, a room temperature is set using a radiator HK, which has a first thermostat TH1. The radiator and the first thermostat form the first consumer V1. A second room R2 is heated or cooled by an underfloor heating system FB, which is controlled by a second thermostat TH2. The underfloor heating system and the second thermostat form a second consumer V2.

[0053] The first and second rooms may have doors to other rooms. Furthermore, these rooms may also have doors and windows leading outside. These doors and windows are not shown in Figure 1.

[0054] These thermostats are so-called smart thermostats. They can receive and send messages, especially wirelessly. These messages include, for example, the current room temperature, the opening degree of a radiator or underfloor heating valve, the current room temperature to be achieved, and / or a temperature profile for one or more days. Furthermore, these thermostats can determine the current room temperature and regulate a preset room temperature by opening or closing a respective valve on the radiator or underfloor heating.

[0055] Figure 1 also shows a distribution device EVE. This provides temperature profiles TP1 and TP2 for the two consumers. A user can communicate their daily and hourly room temperature requirements for the two rooms as a temperature profile, particularly using their mobile phone MOB. For example, in the first room R1, a living room, a temperature of 17°C (Celsius) should prevail every day from 00:00 to 08:00, a temperature of 21.5°C from 06:00 to 23:00, and then a temperature of 19°C from 23:00 to 24:00. Similarly, in the second room R2, a bathroom, the temperature should be as follows:

[0056] Time from ... to Temperature

[0057] 00:00 - 05:30 21.0° C

[0058] 05:30 - 08:30 23.0° C

[0059] 08:30 - 18:00 21.0° C

[0060] 18:00 - 22:30 23.0° C

[0061] 22:30 - 24:00 21.0° C

[0062] In addition, a tolerance profile OP1, OP2 is provided for each room in the EVE energy distribution unit. Users can also create or modify these profiles via their mobile device (MOB) and make them available to the EVE energy distribution unit.

[0063] The first tolerance profile OP1 for the first room specifies that the minimum temperature in the first room may be 18° C and the maximum temperature 22.5° C. For the second room, the second tolerance profile OP2 specifies that the room temperature between 05:30 and 22:30 may be a maximum of 0.5° C below the respective temperature value of the second temperature profile and that the maximum temperature in the second room may be 25° C. Between 22:30 and 24:00 and between 00:00 and 5:30 the temperature may be a maximum of 2° C colder than the temperature specified by the second temperature profile. In addition, the first tolerance profile indicates that this must be applied before the second tolerance profile OP2. This means that the tolerances in the first room must be applied first, and only when these have been reached or exhausted, e.g. the maximum or minimum temperature has been reached, then the second tolerance profile for the second room is applied.

[0064] The EVE distribution device also has room profiles RP1 and RP2 for the two rooms. Each room profile indicates how much energy is required per hour to heat or cool the room by 1°C. This value varies depending on the outside temperature. It may also indicate how much energy can be gained from solar radiation, for example, if the room has a south-facing window. Ventilation losses can also be taken into account.

[0065] In addition, the distribution device receives information via MSG messages from two energy suppliers regarding how much energy EP1 and EP2 can provide within a specified time period ZD. The first energy supplier is a gas supplier that can supply a specific amount of gas that can be converted into district heating. The second energy supplier is a wind turbine that provides electrical energy that heats the district heating water. Thus, the energy distribution unit determines the available energy EP = EP1 + EP2 for several future time periods ZA1, ZA2, and ZA3, where these time periods are disjoint.

[0066] For example, the available energy in kWh is distributed as follows:

[0067] Time period EP1 EP2 EP=EP1+EP2

[0068] ZA1 15 25 40

[0069] ZA2 20 0 20

[0070] ZA3 10 30 40

[0071] The distribution device determines for each consumer based on the current room temperature TA1, TA2, the temperature profile and the room profile which thermal energy EB1, EB2 is required in the several future time periods ZA1, ZA2, ZA3.

[0072] For example, the required thermal energy in kWh is distributed as follows:

[0073] Time period EB1 EB2 EB=EB1+EB2

[0074] ZA1 20 15 35

[0075] ZA2 20 15 35

[0076] ZA3 15 25 40

[0077] Thus, sufficient thermal energy is available in the first and third time periods for the two consumers to heat the two rooms according to the temperature profiles, EB < EP. However, in the second time period, the two energy suppliers cannot supply enough energy together, EB > EP.

[0078] The distribution device can pursue two options, taking into account the respective tolerance profiles OP1, OP2 of the rooms: a) In the first option, the temperature in the first room is reduced, whereby the required energy is reduced to such an extent that the energy provided is sufficient to heat both rooms, since the room temperature of the first room does not fall below the minimum temperature when the temperature is lowered. b) In a second option, more heat is supplied to the first room as required by the first temperature profile. In the second time period, the heat supply to the first room is then reduced, whereby because the room temperature was too high during the first time period, the room temperature in the second time period does not fall below the room temperature required by the temperature.

[0079] Depending on the selected option, the distribution device generates a respective control signal S1, S2, which it sends to the respective thermostats of the consumers. The respective control signal indicates how far a respective valve of the radiator or underfloor heating should be opened or closed. The signal is either transmitted from the distribution device to the respective thermostats in specified time units or it includes a description of how far the respective valves should be opened or closed over time by the respective thermostat. Alternatively, the control signal S1, S2 can specify a desired room temperature that the consumer is to reach. This can also be used to prevent overheating or underheating of a particular room.

[0080] The distribution device EVE has at least one processing unit CPU for executing the individual steps, a memory unit MEM for storing an executable code that contains the processing steps to be carried out and for storing temperature profiles, room profiles and tolerance profiles and input and output interfaces I / O with which messages can be exchanged with the consumers and the energy suppliers.

[0081] Figure 2 shows a flowchart of the core of the invention. After starting in S1, the following steps are executed:

[0082] - S2: Providing a temperature profile, a tolerance profile and a room profile for the respective room;

[0083] - S3: Determine the current room temperature of the respective room;

[0084] - S4: Determining an available energy from at least one energy supplier for several future time periods;

[0085] - S5: Determination of the thermal energy required for each consumer for the several future time periods, taking into account the current room temperatures, the temperature profiles, the tolerance profiles, the room profiles and the available energy;

[0086] - S6: Determining a control signal for each consumer based on the respective required thermal energy, whereby the respective control signal controls a supply of thermal energy by the respective consumer.

[0087] The flowchart ends in step S7. The invention is applied in an energy distribution station, such as for a street, a city block, a district, or an entire city. The consumer releases thermal energy into the room in the form of heat or cold, which in turn generates the thermal energy using electrical energy or hot water. The room can be a living space or a process vessel in a production facility.

[0088] It should be noted that regardless of the grammatical gender of a particular term, persons with male, female or other gender identities are included within the scope of this description.
