Description

System and method for optimizing hot water management using renewable energy

[0001] The present invention relates to a hot water management optimization system and method, and more particularly, to a hot water management optimization system and method using renewable energy that can stably supply hot water using renewable energy, particularly solar and wind power, while maximizing the utilization of renewable energy.

[0002] Remote areas, islands, and low-density population centers with inadequate heating infrastructure face challenges in power generation and supply. These areas require distributed resources, such as stand-alone microgrids, to provide self-sufficient power. This distributed resource is driven by the global trend toward greenhouse gas reduction and low-cost renewable energy. Renewable energy sources such as solar and wind power are utilized for power supply, while solar thermal energy is used for hot water.

[0003] In areas like the above, it's difficult to reliably supply hot water for domestic and heating needs to the facilities in need. Solar energy is often used to supply these needs. Typically, hot water is primarily consumed during sunrise, sunset, and nighttime hours. Therefore, in solar thermal systems, collectors capture solar energy during the day and transfer the energy to a storage tank. The storage tank then uses the solar energy to generate hot water and store it.

[0004] Meanwhile, in solar thermal systems, the storage tank is initially sized to match the energy production of the collectors. Consequently, fluctuations in hot water usage make it difficult to manage the solar energy in the storage tank. For example, if hot water usage is low compared to the energy production of the collectors, the water temperature in the storage tank may exceed the setpoint. To maintain the water temperature below the setpoint, hot water from the storage tank is discharged and discarded, cold water is supplied to the tank, or the collectors are blocked by a shading curtain. This means that solar energy captured by the solar thermal system is either wasted or unused. Furthermore, if hot water usage is high compared to the energy production of the collectors, or if weather conditions make it difficult for the collectors to collect solar heat, energy from other devices (such as a boiler) must be supplied to the storage tank to generate hot water and maintain the water temperature. This process of generating energy from these other devices can also generate greenhouse gases. Because of this, the solar energy in the storage tank needs to be managed so that it can be used efficiently.

[0005] The technical problem to be solved by the hot water management optimization system and method according to the technical idea of ​​the present invention is to provide a hot water management optimization system and method that can stably generate hot water using renewable energy regardless of the weather, maintain the water temperature, and supply it to demand facilities.

Here, the control unit (104) can generate a control signal corresponding to the extracted process information and transmit it to the hot water production storage device (10). In addition, the hot water production storage device (10) can be operated to correspond to the extracted process information according to the control signal. Accordingly, the control unit (104) can operate the hot water production storage device (10) based on the status information and the predicted status information, so as to generate hot water using solar and wind power and supply it to the demand facility (20) by taking into account the status of the hot water production storage device (10).

[0100] For example, the process management unit (103) can extract third process information. Here, the control unit (104) can sequentially perform the 31st analysis process, the 31st operation process, the 32nd analysis process, and the 32nd operation process included in the third process information to control the hot water production storage device (10).

[0101] The hot water management optimization system (100) according to the present embodiment is connected to a hot water production storage device (10), a demand facility (20), and an administrator terminal (30), and can control the hot water production storage device (10). In the hot water production storage device (10), a heat storage tank (110) can produce hot water by combining with a solar collector (130) that collects solar heat, and a backup heat storage tank (140) can produce hot water by a heat transfer unit (144) supplied with electric energy from a wind power generator (150). Here, the hot water production storage device (10) can supply hot water at an available water temperature to the demand facility (20). In addition, the electric energy of the wind power generator (150) can be stored in an energy storage unit (160) and supplied to the heat transfer unit (144) as needed. That is, on sunny and windy days, hot water can be generated by the heat of the heat transfer unit (144) operated by the solar heat collected in the collector (130) and the wind power generator (150), and on sunny and windy days, hot water can be generated by the heat of the heat transfer unit (144) operated by the energy storage unit (160). Therefore, the hot water management optimization system (100) according to the present embodiment can stably generate hot water and maintain the water temperature regardless of the weather by using renewable energy, particularly solar and wind power, so that it can be supplied to demand facilities.

[0102] In addition, the hot water management optimization system (100) according to the present embodiment can store hot water in the thermal storage tank (110) and the backup thermal storage tank (140) of the hot water production storage device (10) and supply it to the demand facility (20) at an available water temperature. Here, the hot water can be distributed and stored in the thermal storage tank (110) and the backup thermal storage tank (140), so that the cases in which it is discarded without being supplied to the demand facility (20) can be significantly reduced. By reducing the waste of hot water, the loss of solar and wind power used to produce hot water and maintain the water temperature can be prevented. In particular, the electric energy generated from the wind generator (150) can be stored in the energy storage unit (160) and supplied to the heat transfer unit (144) as needed, so that the use of fuel that can generate greenhouse gases can be reduced. Therefore, the hot water management optimization system (100) according to the present embodiment can prevent the loss of renewable energy in the production of hot water and the maintenance of the water temperature, and can prevent the generation of greenhouse gases.

[0103] FIG. 3 is a flowchart illustrating a method for optimizing hot water management according to one embodiment of the present invention.

[0104] As illustrated in FIG. 3, a hot water management optimization method according to an embodiment of the present invention manages energy according to hot water through a hot water production and storage device (10) that can generate and store hot water using solar and wind power, a demand facility (20) that receives and uses hot water generated from the hot water production and storage device (10), and a hot water management optimization system (100) connected to an administrator terminal (30) of an administrator who manages the hot water production and storage device (10) and the demand facility (20). The hot water management optimization method of this embodiment intends to utilize the hot water management optimization system (100) mentioned above.

[0105] A step (S101) may be performed in which the monitoring unit (101) receives operational information and weather information according to the operation of the hot water production storage device (10) and the demand facility (20). In step S101, the operating information may mean data that can be generated from the hot water production storage device (10) and the demand facility (20) when the hot water production storage device (10) and the demand facility (20) are in operation, for example, the storage tank water temperature measured by the storage temperature sensor (115) of the storage tank (110), the supply storage tank water temperature measured by the supply temperature sensor (123) of the supply storage tank (120), the backup storage tank water temperature measured by the backup temperature sensor (143) of the backup storage tank (140), the maximum capacity of the storage tank (110), the flow rate of the inlet pipe (111) of the storage tank (110), the flow rate of the hot water outlet pipe (112) of the storage tank (110), the maximum capacity of the backup storage tank (140), the flow rate of the backup inlet pipe (141) of the backup storage tank (140), the backup of the backup storage tank (140). It may include the flow rate of the outlet pipe (142), the power generation amount of the wind power generator (150), the electric energy storage amount of the energy storage unit (160), the hot water consumption amount of the demand facility (20), etc. In addition, the maximum capacity of the heat storage tank (110) means the maximum amount of water that can be stored in the heat storage tank (110), and the maximum capacity of the backup heat storage tank (140) means the maximum amount of water that can be stored in the backup heat storage tank (140).

[0106] In addition, weather information can be transmitted to the monitoring unit (101) in real time from the administrator terminal (30) while being transmitted to the administrator terminal (30), and can include, for example, weather, temperature, wind speed, etc.

[0107] Next, a step (S102) may be performed in which the monitoring unit (101) generates and stores status information. In step S102, the status information may be generated using operating information and weather information. Here, the status information may mean data generated by processing the operation information transmitted to the monitoring unit (101) for a predetermined period of time (e.g., 24 hours, 7 days, 1 month, etc.) prior to the reference point in units of predetermined periods, and for example, weather information corresponding to the operation information, the water temperature of the upper part of the storage tank (110) by period, the water temperature of the lower part of the storage tank (110) by period, the water temperature between the upper and lower parts of the storage tank (110) by period, the water temperature of the upper part of the backup storage tank (140) by period, the water temperature of the lower part of the backup storage tank (140) by period, the water storage amount of the storage tank (110) by period, the water storage amount of the incandescent storage tank (110) by period, the power generation amount of the wind power generator (150) by period, the electric energy storage amount of the energy storage unit (160) by period, the hot water consumption amount of the demand facility (20) by period, and the standard hot water of the demand facility (20). Consumption, etc. may be included. Here, the water storage amount of the storage tank (110) by period may refer to the amount of water stored in the storage tank (110) for a predetermined period, and the water storage amount of the backup storage tank (140) by period may refer to the amount of water stored in the backup storage tank (140) for a predetermined period. In addition, the reference hot water consumption amount of the demand facility (20) may be generated by combining the average value of the hot water consumption amount of the demand facility (20) for a predetermined period and the frequent value of the hot water consumption amount, and may have a predetermined range and include an upper limit and a lower limit. Such status information may indicate a change trend of data according to the operation information for a predetermined period. For example, if the reference point is 0:00 on July 1, 2022, the predetermined period of 24 hours may be from 0:00 on June 30, 2022 to 23:59 on June 30, 2022.

[0108] Next, a step (S103) may be performed in which the status prediction unit (102) generates predicted status information based on the status information stored in the monitoring unit (101). In step S103, the predicted status information may refer to data predicting the operating status of the hot water production storage device (10) and the demand facility (20) for a set period (e.g., 12 hours, 24 hours, etc.) by considering weather information after a reference point in time, and may include, for example, a predicted water temperature at the upper part of the storage tank (110), a predicted water temperature at the lower part of the storage tank (110), a predicted water temperature between the upper and lower parts of the storage tank (110), a predicted water temperature at the upper part of the backup storage tank (140), a predicted water temperature at the lower part of the backup storage tank (140), a predicted hot water storage amount of the storage tank (110), a predicted hot water storage amount of the backup storage tank (140), a predicted hot water consumption amount of the demand facility (20), etc.

[0109] Next, a step (S104) may be performed in which the process management unit (103) extracts process information corresponding to the status information and the status prediction information. Step S104 may be performed by extracting one of a plurality of process information stored in the process management unit (103), and may extract process information corresponding to the combined status information and the status prediction information by combining the status information and the status prediction information. Here, the process information may be information including the contents to be analyzed in the predicted status information and the status information according to the predicted status information and the status information, and the operation contents of the hot water production storage device (10) to be performed according to the results of the analysis.

[0110] In step S104, the process management unit (103) can compare the predicted hot water consumption of the demand facility (20) of the predicted status information with the reference hot water consumption of the demand facility (20) of the status information, check the operation of the collector (130) and the wind power generator (150) of the hot water production storage device (10) according to the weather information, and check the predicted water temperature of the upper part of the storage tank (110), the predicted water temperature of the lower part of the storage tank (110), the predicted water temperature between the upper and lower parts of the storage tank (110), the predicted water temperature of the upper part of the backup storage tank (140), the predicted water temperature of the lower part of the backup storage tank (140), the predicted hot water storage amount of the storage tank (110), and the predicted hot water storage amount of the backup storage tank (140).

[0111] Additionally, in step S104, when the predicted hot water consumption is greater than the upper limit of the reference hot water consumption, i.e., when the hot water consumption is predicted to be greater than the reference value, the process management unit (103) can extract the first process information. The first process information can include the 11th analysis process, the 11th operation process, the 12th analysis process, the 12th operation process, and the 13th operation process.

[0112] The eleventh analysis process may include a process of comparing the predicted hot water storage capacity of the storage tank (110) with the predicted hot water consumption capacity of the demand facility (20).

[0113] The eleventh operating process may include a process of supplying water from the supply storage tank (120) to the storage tank (110) and maintaining the hot water storage amount and the water temperature of the storage tank (110) at values ​​that can be supplied to the demand facility (20) when the predicted hot water storage amount of the storage tank (110) in the eleventh analysis process is greater than the predicted hot water consumption amount of the demand facility (20), i.e., when hot water can be supplied by the storage tank (110) and the collector (130). Here, water may be supplied from the supply storage tank (120) to the storage tank (110) in an amount equal to the difference between the predicted hot water consumption amount of the storage tank (110) and the upper limit of the reference hot water consumption amount.

[0114] The 12th analysis process may include a process of comparing the predicted hot water storage amount of the backup thermal storage tank (140) and the difference between the predicted hot water storage amount of the thermal storage tank (110) and the predicted hot water consumption amount of the demand facility (20) when the predicted hot water storage amount of the thermal storage tank (110) is less than the predicted hot water consumption amount of the demand facility (20) in the 11th analysis process, i.e., when hot water cannot be supplied by the thermal storage tank (110) and the collector (130).

[0115] The 12th operation process may include a process in which the backup storage tank (140) supplies hot water having a temperature that can be supplied to the demand facility (20) to the demand facility (20) when the predicted hot water storage amount of the backup storage tank (140) is greater than or equal to the difference between the predicted hot water storage amount of the storage tank (110) and the predicted hot water consumption in the 12th analysis process, i.e., when hot water can be supplied by the backup storage tank (140). Here, hot water may be supplied to the demand facility (20) from the backup storage tank (140) in an amount equal to the difference between the predicted hot water storage amount of the storage tank (110) and the predicted hot water consumption. In addition, the 12th operation process may further include a process of supplying water from the storage tank (110) to the backup storage tank (140) after a set period of time in an amount equal to the difference between the predicted hot water storage amount of the storage tank (110) and the predicted hot water consumption amount, and operating the heat transfer unit (144) to maintain the water temperature of the backup storage tank (140) at a temperature that can be supplied to the demand facility (20).

[0116] The 13th operating process may include a process of operating the heat transfer unit (144) to supply water from the heat storage tank (110) to the backup heat storage tank (140) and to supply the water to the demand facility (20) when the predicted hot water storage amount of the backup heat storage tank (140) in the 12th analysis process is less than the difference between the predicted hot water storage amount of the heat storage tank (110) and the predicted hot water consumption, i.e., when the hot water cannot be supplied by the backup heat storage tank (140). Here, when water is supplied from the heat storage tank (110) to the backup heat storage tank (140), the amount of water supplied may be equal to the difference between the predicted hot water storage amount of the heat storage tank (110) and the predicted hot water consumption and the predicted hot water storage amount of the backup heat storage tank (140). Additionally, the 13th operating process may include a process in which the energy storage unit (160) supplies the amount of electric energy required by the heating unit (144) to the heating unit (144) or a process in which grid power is supplied to the heating unit (144) when the energy storage unit (160) stores less electric energy than the amount required by the heating unit (144).

[0117] Additionally, in step S104, when the predicted hot water consumption is less than the lower limit of the reference hot water consumption, i.e., when the hot water consumption is predicted to be less than the reference value, the process management unit (103) can extract second process information. The second process information can include the 21st analysis process, the 21st operation process, the 22nd analysis process, the 22nd operation process, and the 23rd operation process.

[0118] The 21st analysis process may include a process of comparing the predicted hot water storage capacity of the storage tank (110) with the maximum capacity of the storage tank (110) and checking the water temperature of the storage tank (110).

[0119] The 21st operating process may include a process of supplying water from the supply storage tank (120) to the storage tank (110) to reach a water temperature of the storage tank (110) that can be supplied to the demand facility (20) when the predicted hot water storage capacity of the storage tank (110) in the 21st analysis process is less than the maximum capacity of the storage tank (110) and the water temperature of the storage tank (110) is higher than the water temperature that can be supplied to the demand facility (20).

[0121] The 22nd operation process may include a process of supplying water from the storage tank (110) to the backup storage tank (140) in an amount equal to the difference between the predicted hot water storage amount of the backup storage tank (140) and the maximum capacity of the backup storage tank (140) when the difference between the predicted hot water storage amount of the storage tank (110) and the maximum capacity of the backup storage tank (140) is greater than the difference between the predicted hot water storage amount of the storage tank (110) and the maximum capacity of the storage tank (110), i.e., when surplus hot water can be stored in the backup storage tank (140). In addition, the 22nd operating process may include a process of supplying water from the supply storage tank (120) to the storage tank (110) in the amount supplied to the backup storage tank (140) from the storage tank (110) and reaching a water temperature that can be supplied to the demand facility (20) through the collector (130), and may include a process of maintaining the water supplied to the backup storage tank (140) at a water temperature that can be supplied to the demand facility (20) using the heat transfer unit (144).

[0122] The 23rd operation process may include a process of supplying water from the storage tank (110) to the backup storage tank (140) in an amount equal to the difference between the predicted hot water storage amount of the backup storage tank (140) and the maximum capacity of the backup storage tank (140) in the 22nd analysis process, when the difference between the predicted hot water storage amount of the storage tank (110) and the maximum capacity of the storage tank (110) is less than the difference between the predicted hot water storage amount of the storage tank (110) and the maximum capacity of the storage tank (110), i.e., when the surplus hot water cannot be completely stored in the backup storage tank (140), and discharging and discarding from the storage tank (110) an amount that cannot be supplied to the backup storage tank (140).

[0123] Additionally, in step S104, when the predicted hot water consumption corresponds between the upper and lower limits of the reference hot water consumption, i.e., when the hot water consumption is predicted to be at the reference level, the process management unit (103) can extract third process information. The third process information can include a 31st analysis process, a 31st operation process, a 32nd analysis process, and a 32nd operation process.

[0124] The 31st analysis process may include a process of comparing the predicted hot water storage amount of the storage tank (110) with the predicted hot water consumption amount.

[0125] The 31st operating process may include a process of supplying water from the supply storage tank (120) to the storage tank (110) and maintaining the hot water storage amount and water temperature of the storage tank (110) at a level that can be supplied to the demand facility (20) when the predicted hot water storage amount of the storage tank (110) is greater than the predicted hot water consumption amount in the 31st analysis process, i.e., when hot water can be supplied by the storage tank (110) and the collector (130).

[0126] The 32nd analysis process may include a process of comparing the predicted hot water storage amount of the backup thermal storage tank (140) and the difference between the predicted hot water storage amount of the thermal storage tank (110) and the predicted hot water consumption amount of the demand facility (20) when the predicted hot water storage amount of the thermal storage tank (110) is less than the predicted hot water consumption amount in the 31st analysis process, i.e., when hot water cannot be supplied by the thermal storage tank (110) and the collector (130).

[0127] The 32nd operation process may include a process in which the backup storage tank (140) supplies hot water having a temperature that can be supplied to the demand facility (20) to the demand facility (20) when the predicted hot water storage amount of the backup storage tank (140) is greater than or equal to the difference between the predicted hot water storage amount of the storage tank (110) and the predicted hot water consumption in the 32nd analysis process, i.e., when hot water can be supplied by the backup storage tank (140). Here, hot water may be supplied to the demand facility (20) from the backup storage tank (140) in an amount equal to the difference between the predicted hot water storage amount of the storage tank (110) and the predicted hot water consumption. In addition, the 32nd operation process may further include a process of supplying water from the storage tank (110) to the backup storage tank (140) after a set period of time by the difference between the predicted hot water storage amount of the storage tank (110) and the predicted hot water consumption amount, and operating the heat transfer unit (144) to maintain the water temperature of the backup storage tank (140) at a temperature that can be supplied to the demand facility (20).

[0128] Additionally, at step S104, the process management unit (103) can extract process information based on the predicted power generation amount of the wind power generator (150).

[0129] For example, in step S104, when the predicted power generation of the wind power generator (150) is greater than 0, i.e., when the wind power generator (150) is in operation, the process management unit (103) can extract the fourth process information. The fourth process information can include the 41st analysis process, the 42nd analysis process, the 41st operation process, the 42nd operation process, and the 43rd operation process.

[0130] The 41st analysis process may include a process of comparing the water temperature at the upper part of the backup storage tank (140) and the water temperature at the lower part of the backup storage tank (140) with the water temperature that can be supplied to the demand facility (20).

[0131] The 42nd analysis process may include a process of comparing the electric energy storage capacity of the energy storage unit (160) and the maximum storage capacity of the energy storage unit (160) when the water temperature of the upper part of the backup storage tank (140) and the water temperature of the lower part of the backup storage tank (140) are each higher than the water temperature that can be supplied to the demand facility (20) in the 41st analysis process.

[0132] The 41st operating process may include a process in which the wind power generator (150) supplies and stores electric energy to the energy storage unit (160) when the electric energy storage capacity of the energy storage unit (160) in the 42nd analysis process is less than the maximum storage capacity of the energy storage unit (160).

[0135] Additionally, in step S104, when the predicted power generation of the wind power generator (150) is 0, the process management unit (103) can extract fifth process information. The fifth process information can include a 51st analysis process, a 52nd analysis process, a 51st operation process, and a 52nd operation process.

[0136] The 51st analysis process may include a process of comparing the water temperature at the upper part of the backup storage tank (140) and the water temperature at the lower part of the backup storage tank (140) with the water temperature that can be supplied to the demand facility (20).

[0138] The 51st operating process may include a process in which the energy storage unit (160) supplies electric energy to the heating unit (144) when the electric energy storage amount of the energy storage unit (160) in the 52nd analysis process is greater than 0 and less than the maximum storage amount of the energy storage unit (160).

[0139] The 52nd operation process may include a process in which the system equipment supplies electric energy to the heating unit (144) when the electric energy storage amount of the energy storage unit (160) is 0 in the 52nd analysis process.

[0140] Next, a step (S105) may be performed in which the control unit (104) controls the hot water production storage device (10) according to the process information extracted from the process management unit (103). In step S105, the control unit (104) may generate a control signal corresponding to the extracted process information and transmit it to the hot water production storage device (10). In addition, the hot water production storage device (10) may be operated to correspond to the extracted process information according to the control signal. Accordingly, the control unit (104) may operate the hot water production storage device (10) based on the status information and the predicted status information, so as to generate hot water using solar and wind power and supply it to the demand facility (20) in consideration of the status of the hot water production storage device (10).

[0141] For example, in step S104, the process management unit (103) can extract third process information. Accordingly, in step S105, the control unit (104) can sequentially perform the 31st analysis process, the 31st operation process, the 32nd analysis process, and the 32nd operation process included in the third process information to control the hot water production storage device (10).

[0142] The hot water management optimization method according to the present embodiment is connected to a hot water production storage device (10), a demand facility (20), and a manager terminal (30), and can control the hot water production storage device (10). In the hot water production storage device (10), a heat storage tank (110) can produce hot water by combining with a solar collector (130) that collects solar heat, and a backup heat storage tank (140) can produce hot water by a heat transfer unit (144) supplied with electric energy from a wind power generator (150). Here, the hot water production storage device (10) can supply hot water at an available water temperature to the demand facility (20). In addition, the electric energy of the wind power generator (150) can be stored in an energy storage unit (160) and supplied to the heat transfer unit (144) as needed. That is, on sunny and windy days, hot water can be generated by the heat of the heat transfer unit (144) operated by the solar heat collected in the collector (130) and the wind power generator (150), and on sunny and windy days, hot water can be generated by the heat of the heat transfer unit (144) operated by the energy storage unit (160). Therefore, the hot water management optimization method according to the present embodiment can stably generate hot water and maintain the water temperature regardless of the weather by using renewable energy, particularly solar and wind power, so that it can be supplied to demand facilities.

[0143] In addition, the hot water management optimization method according to the present embodiment can store hot water in the thermal storage tank (110) and the backup thermal storage tank (140) of the hot water production storage device (10) and supply it to the demand facility (20) at an available water temperature. Here, the hot water can be distributed and stored in the thermal storage tank (110) and the backup thermal storage tank (140), so that the cases in which it is discarded without being supplied to the demand facility (20) can be significantly reduced. By reducing the waste of hot water, the loss of solar and wind power used to produce hot water and maintain the water temperature can be prevented. In particular, the electric energy generated from the wind generator (150) can be stored in the energy storage unit (160) and supplied to the heat transfer unit (144) as needed, so that the use of fuel that can generate greenhouse gases can be reduced. Therefore, the hot water management optimization method according to the present embodiment can prevent the loss of renewable energy in the production of hot water and the maintenance of the water temperature, and can prevent the generation of greenhouse gases.
