Description

  The present invention relates to an energy management device for heat pump equipment.

  Today, due to environmental considerations, it is required to increase the proportion of natural energy.

  However, natural energy is susceptible to weather changes. As wind power and solar power generation increase, the amount of power generation increases and decreases depending on the weather. If the total power generation and the total power consumption do not match, the frequency of the power system changes. When the frequency changes, a fault occurs in the power system. In order to match the total power generation amount and the total power consumption, there is a method of adjusting the power supply such as storing surplus power in the storage battery and supplementing with the power of the storage battery when the power generation amount is insufficient. However, storage batteries are still expensive, and it is difficult to deploy storage batteries sufficient for adjustment. Therefore, a method for adjusting the power demand has been proposed. For example, in Patent Document 1 (Japanese Patent Application Laid-Open No. 2006-353079), by controlling the power consumption of a plurality of specific loads connected to an electric power system via a communication line, There has been proposed a power system stabilization system that matches the total amount of power consumption in time series and stabilizes the frequency of the power system.

  However, in the power system stabilization system described in Patent Document 1, the total amount of generated power in time series and the total amount of power consumption in time series are matched, but the power consumption is instantaneously adjusted by detecting the mismatch. Is difficult and expensive to operate. In addition, the power system stabilization system described in Patent Document 1 uses a specific load, which is a power consumption control target, as a vending machine compressor, a river drainer, or a pump for pumping agricultural water.

  In the present embodiment, the heat pump device 40 is a heating and hot water supply device, and can heat and hot water in a living room. The heat pump device 40 includes a heat pump unit 41, a hot water storage tank 42, a hot water supply pipe 43, a heating circulation circuit 44, and a heat pump device control device 100.

  The heat pump unit 41 includes the refrigerant circuit 16 and boiles water sent from the hot water storage tank 42 to make warm water. The refrigerant circuit 16 is mainly configured by sequentially connecting a compressor 12, a hydrothermal exchanger 13 as a radiator, an electric expansion valve 15 as an expansion mechanism, and an evaporator 11. The water heat exchanger 13 is a heat exchanger that functions as a refrigerant condenser.

The hot water storage tank 42 stores the hot water heated by the heat pump unit 41. Inside the hot water storage tank 42, a plurality of sensors (not shown) are installed vertically, and these sensors sense the temperature of the hot water in the hot water storage tank and transmit temperature information to the heat pump device control apparatus 100. . The hot water storage tank 42 is connected to the heat pump unit 41 via a boiling circulation circuit 45. The boiling circulation circuit 45 passes the relatively low temperature hot water at the bottom of the hot water storage tank 42 through the water heat exchanger 13 and returns it to the hot water storage tank 42.

  The hot water supply pipe 43 is branched from a water supply pipe to which water is supplied, and is drawn into a hot water supply heat exchanger 32 provided in the hot water storage tank 42, and tap water supplied from the water supply pipe is converted into a hot water supply heat exchanger. 32 is a pipe that exchanges heat with hot water in the hot water storage tank 42 by 32 to supply hot water to a kitchen, bathtub, shower, etc. in the home.

By returning and circulating in the hot water storage tank 42, a plurality of radiators 48 are used as heating appliances in the room.

The heat pump device control apparatus 100 controls components such as the compressor 12 of the heat pump device 40. For example, when the temperature of the hot water in the hot water storage tank 42 falls below a predetermined lower limit, the heat pump device control apparatus 100 starts the boiling operation until the temperature of the hot water rises to a predetermined temperature. In the boiling operation, the hot water in the hot water storage tank 42 is caused to flow to the heat pump unit 41 via the boiling circulation circuit 45, the hot water is heated through the hydrothermal exchanger 13, and returned to the hot water storage tank 42. Moreover, the heat pump apparatus control apparatus 100 controls the component of the heat pump apparatus 40 based on the operation plan 103b mentioned later. The operation plan 103b is input and set by the user from the remote controller 130, and is also created by learning the daily operation data 103a of the heat pump device 40 by the heat pump device control apparatus 100. Further, the heat pump device control apparatus 100 controls the components of the heat pump device 40 according to an operation by the user via the remote controller 130.

  The display unit 105 and the input unit 106 are provided in the remote controller 130. The display unit 105 is a touch panel type liquid crystal screen. Therefore, the liquid crystal screen also has a function as the input unit 106. In addition, the remote controller 130 also includes an operation button, and the button also has a function as the input unit 106.

(4-2-1) Demand side information transmitter 102a
The demand side information transmission part 102a transmits the energy consumption plan value and energy consumption performance value of the heat pump apparatus 40 to the heat pump apparatus energy management apparatus 110. Specifically, the demand side information transmission unit 102a transmits the individual consumption plan 121, which is data stored in the storage unit 103, to the heat pump device energy management apparatus 110 via the communication unit 101. For example, as shown in FIG. 5, the individual consumption plan 121 includes energy consumption plan values for the time zone of the current day and the next day (for example, every minute). Moreover, the energy consumption performance value for every time zone (for example, every minute) which has already passed is also included.

  Specifically, for example, when the schedule set by the user exists, the operation plan creation unit 102c creates the operation plan 103b based on the schedule.

  When the operation data 103a is stored, the operation data 103a is learned, and the operation plan 103b is created based on the learning result. Learning is performed, for example, by calculating the driving with the highest probability for each time zone.

  When both the schedule and the operation data 103a exist, the operation plan 103b is created based on the learning result of the schedule and the operation data 103a.

  If neither the schedule nor the operation data 103a exists, the plan that is preset in advance is set as the operation plan 103b.

  In any case, when the unit price of energy is relatively low, for example, the operation plan 103b is created so that energy is consumed as much as possible at night.

  Or when the individual consumption request | requirement 124 is memorize | stored in the memory | storage part 103, the individual consumption request | requirement 124 is referred and the operation plan 103b is created so that the individual consumption request | requirement 124 may be followed. For example, as shown in FIG. 9, the operation plan 103b has an output of 25%, that is, the compressor 12 is rated at a time zone (0:01) where the lower limit of use is defined as 25% of the rating. It operates at a rotational speed of 25% or more, generates hot water, and stores surplus energy as heat. In a time zone (17:00) in which the upper limit of use is determined to be 50% of the rating, heating is performed at an output of 50%, that is, the compressor 12 is not operated at a rotational speed exceeding 50% of the rating.

  The operation plan 103 b is stored in the storage unit 103.

(4-2-4) Consumption plan creation unit 102d

That is, the operation plan 103b is converted into the individual consumption plan 121. Specifically, the storage unit 103 stores data related to the rated energy consumption of the heat pump device 40. The consumption plan creation unit 102d refers to the data, calculates the amount of energy consumed for each time zone (for example, every minute) based on the operation plan 103b, and stores it in the storage unit 103 as the individual consumption plan 121.

(4-2-5) Operation data recording unit 102e

In addition, the operation data recording unit 102e includes the actual value of energy consumption for each time zone (for example, every minute), that is, the actual energy consumption value included in the individual consumption plan 121 and causes the storage unit 103 to store it.

(4-2-6) Operation control unit 102f
The operation control unit 102f controls the heat pump device 40 according to the operation plan 103b. In addition, the operation control unit 102f controls the heat pump device 40 in accordance with a user instruction input via the remote controller 130.

(5) Operation (5-1) Overall Operation The overall operation of the energy demand adjustment system 1 described above is summarized from the viewpoint of the heat pump device energy management apparatus 110 as shown in the flowchart of FIG.

  In step S <b> 101, the heat pump device energy management apparatus 110 collects the energy consumption plan value and the actual value from each heat pump device 40. Specifically, the energy consumption information collection unit 112 c receives the individual consumption plan 121 transmitted from each heat pump device 40 via the communication unit 111 and stores the individual consumption plan 121 in the storage unit 113.

  In the next step S <b> 102, the heat pump device energy management apparatus 110 aggregates the energy consumption plan values of the heat pump devices 40 and transmits them to the energy control device 90. Specifically, the totaling unit 112d totals the energy consumption plan value and the actual value included in the individual consumption plan 121 of each heat pump device 40 in the storage unit 113, and the total result is stored in the storage unit 113 as the total consumption plan 122. Remember. The demand side provided information transmission unit 112 a transmits the total consumption plan 122 to the energy control device 90 via the communication unit 111.

  In the next step S103, the heat pump device energy management device 110 receives the recommended energy consumption value from the energy control device 90 as a target value for the amount of energy to be consumed. Specifically, when information related to the recommended energy consumption value is transmitted as the total consumption request 123 from the energy control device 90, the supply side provided information receiving unit 112b receives the total consumption request via the communication unit 111. 123 is stored in the storage unit 113. The total consumption request 123 includes recommended energy consumption values for each time zone (for example, every minute). The total consumption request 123 is data as shown in FIG. 7, for example. For example, in the time zone of 0:01 minutes, the recommended value of the total consumption request 123 is larger than the planned value of the total consumption plan 122 shown in FIG. In the time zone of 17:00, the recommended value of the total consumption request 123 is smaller than the planned value of the total consumption plan 122, so that consumption suppression is requested.

  In the next step S <b> 104, the heat pump device energy management apparatus 110 determines an adjustment amount and incentive (reward or fine) of energy consumption of each heat pump device 40, and transmits the adjustment amount and incentive to each heat pump device 40. Specifically, the allocation unit 112f allocates an adjustment amount and incentive for energy consumption to each heat pump device 40. The adjustment amount of energy consumption is determined so that the total energy consumption becomes the recommended energy consumption value included in the total consumption request 123. Incentives are rewards or fines negotiated in advance with the power company. The allocated adjustment amount and incentive are transmitted as an individual consumption request 124 by the energy consumption request unit 112e to each heat pump device 40 via the communication unit 111. The individual consumption request 124 to be transmitted is, for example, data as shown in FIG. For example, in the time zone of 0:01 minutes, the recommended value of the total consumption request 123 is larger than the planned value of the total consumption plan 122, so the lower limit of use is 25% of the rated capacity of the heat pump device 40 in order to promote consumption. As stated above, the reward is set at £ 0.5 as an incentive. In the 17:00 time zone, the recommended value of the total consumption request 123 is smaller than the planned value of the total consumption plan 122, so the upper limit of use is set to 50% or less of the rated capacity of the heat pump device 40 in order to suppress consumption. As an incentive, the reward is set at £ 0.50.

  Thereafter, the flow returns to step S101.

(5-2) Details of Allocation Processing Next, allocation processing for allocating compensation amounts and fines as adjustment amounts and incentives for energy consumption will be described below.

  The amount of energy consumption to be allocated to each heat pump device 40, that is, each consumer is determined by the energy consumption request unit 112e using the following equation (1).

here,
ΔPi: Energy consumption adjustment amount at customer i,
ΔP total: total energy consumption adjustment amount,
αi: Adjustment factor for customer i,
Pi max: the maximum value of the rated energy consumption of the device at the customer i or the adjustable energy consumption at the customer i,
γ: Adjustment magnification (1 or more),
It is.

  The total consumption energy adjustment amount ΔP total is, as an example of the total consumption plan 122 in FIG. 6 and the total consumption request in FIG. It is 0.4 MWh which is a difference from the recommended value 0.6 MWh.

  The adjustment coefficient αi is a different weight depending on the type of consumer. For example, when the consumer is an office building, a store, and a hospital, it is predicted that the adjustment of energy consumption is the most difficult in the hospital. Store: Hospital = 10: 5: 1

  As a result, it is possible to allocate a large amount of adjustment to a type of consumer whose energy consumption is easy to adjust, and to allocate a small amount of adjustment to a type of consumer who is difficult to adjust.

  In addition, since the adjustment factor γ does not necessarily adjust the energy consumption as required by all consumers, for example, when considering a 10% margin, the margin can be taken into consideration when γ = 1.1.

  The amount of compensation or punishment that is an incentive is allocated to each consumer in proportion to the amount of adjustment.
