The present invention relates to a virtual resource plant and a method for operating the same.

In recent years, various efforts have been made on energy management systems (EMS) with the aim of efficiently operating distributed energy facilities. Patent Document 1 discloses an operation plan creation device for a distributed energy system that can create an operation plan that enables efficient energy interchange. Patent Document 2 discloses a control device for a virtual power plant (VPP) that appropriately controls the charging and discharging operations of the entire group of vehicles that make up the VPP according to the state of the vehicles.

Patent No. 6520462 JP 2021-191133 A

The devices disclosed in Patent Documents 1 and 2 focus on the efficient use of electrical energy. Meanwhile, in recent years, attempts have been made to trade saved electrical energy as virtual electricity in the market (capacity market) (also known as negawatt trading). However, in order to be traded in the capacity market, it is required to be able to supply a certain amount of electrical power for a certain amount of time, which may hinder the efficient use of electrical energy. Similar issues may arise not only with electrical energy, but also with general resources such as water resources.

The present invention aims to provide a virtual resource plant that enables more efficient use of resources.

The virtual resource plant of the present invention has a plurality of virtual resource supply facilities capable of supplying virtual resources, and an operation plan creation means for creating an operation plan for the plurality of virtual resource supply facilities. The operation plan creation means receives a request for a specific virtual resource in which a requested supply time and a requested resource amount are specified, and creates an operation plan so that two or more virtual resource supply facilities among the plurality of virtual resource supply facilities share the specific virtual resource.

The present invention provides a virtual resource plant that enables more efficient use of resources.

1 is a schematic diagram of a virtual resource plant according to an embodiment of the present invention; FIG. 1 is a schematic diagram showing an example of operation of the water-related facility of the present invention.

Figure 1 shows an overview of a virtual resource plant 1 according to one embodiment of the present invention. A number of water-related facilities, such as water treatment facilities and water purification facilities, are installed in a specified area. The multiple water-related facilities are interconnected by piping networks 8-11. The specified area is not particularly limited, but it is preferable that the area is relatively limited in order to avoid excessive investment in constructing the piping networks 8-11. The specified area is divided into multiple areas A-C, and each of areas A-C has multiple water-related facilities. Details of the water-related facilities will be described later.

In this embodiment, the virtual resource is electrical energy. Conventionally, the concept of demand response (DR) has been used in relation to electrical energy. DR refers to a mechanism (Daijisen Digital Dictionary) that suppresses the total amount of electrical power consumption by making the unit price of electricity higher during peak power consumption times and by providing some sort of reward in accordance with efforts to conserve power. In this specification, the electrical power used to adjust and control electrical power supply and demand through DR (for example, electrical power obtained through power saving) is referred to as virtual electrical power, and this generalization to all resources is referred to as virtual resources.

The water-related facilities in each of areas A to C are equipped with electric equipment such as pumps. Therefore, each of areas A to C is an area that uses electric energy, but based on a contract with an electric power company (including companies that specialize in power transmission and distribution), it is obligated to conserve electricity under specified conditions at the request of the electric power company. Since the electric power company can freely use the electric energy obtained through power saving, it is equivalent to the electric energy obtained by the electric power company through its own generation. The surplus electricity obtained through the power saving obligation can be considered as virtual electricity (virtual resource). Therefore, each of areas A to C can be said to be a virtual resource supply facility that can supply virtual electricity (virtual resource) to the power transmission and distribution network 21. Furthermore, since the water-related facilities in each of areas A to C can each supply virtual electricity through power saving, they can be said to be individual virtual resource supply facilities.

The electricity transmission and distribution network 21 is operated by an electric power company. Each water-related facility is connected to the electricity transmission and distribution network 21. Power plants 7A to 7C operated by the electric power company are also connected to the electricity transmission and distribution network 21. Each of areas A to C has an area management unit 12A to 12C that manages the area. The area management units 12A to 12C manage the operation of the water-related facilities belonging to the area, and are connected to a database 23, an operation plan creation server 24, and a management server 26, which will be described later, via a communication network 22, which will be described later. The area management units 12A to 12C are composed of computers such as servers, and are connected to each water treatment facility belonging to the area A to C via communication lines (not shown).

The water-related facility may have a power storage facility for storing electrical energy. For example, when electrical energy is supplied to the power company as virtual power (during power saving), the electrical energy stored in the power storage facility may be used to operate the water-related facility. Alternatively, the electrical energy stored in the power storage facility may be supplied to the power transmission and distribution network 21 as actual power equivalent to the virtual power.

The water-related facilities include water treatment facilities 2A-2I, purified water production facilities 3A-3C, sewage treatment facilities 4A-4C, purified water storage facilities 5A, 5B, and sewage storage facility 6. Water treatment facilities 2A-2I are facilities that treat water resources, and treatment includes using the supply water as part of a product, cleaning water, domestic water, industrial water, etc., further purifying the supply water for specific uses (production of pretreated water), and post-treating wastewater generated after using the supply water before discharging it (production of post-treated water). Representative examples of water treatment facilities are houses, factories (machinery, chemical, food, pharmaceutical, etc.), farms, power plants, pure water production plants, office buildings, public facilities, etc.

The purified water production facilities 3A-3C are facilities that produce purified water from raw water, and also include facilities (such as factories with wastewater treatment facilities) that treat wastewater to produce purified water (industrial water or recycled water). The purified water produced by the purified water production facilities 3A-3C is supplied to the water treatment facilities 2A-2I by the water supply system 8, and a portion of it is stored in the purified water storage facilities 5A, 5B by the water supply connection system 10. For example, when the purified water production facilities 3A-3C supply virtual power (during power saving), the purified water stored in the purified water storage facilities 5A, 5B can be released and used by the water treatment facilities 2A-2I. The water supply connection system 10 is also installed between water-related facilities in different areas to accommodate water supply between the areas.

The sewage treatment facilities 4A to 4C treat the sewage or wastewater collected by the sewage system 9. The sewage storage facility 6 stores the sewage or wastewater collected by the sewage communication system 11. The sewage communication system 11 is also used to move sewage or wastewater between different areas.

The virtual resource plant 1 has a database 23, an operation plan creation server 24, an Internet browsing terminal 25, and a management server 26. The virtual resource plant 1 also has a communication network 22 that interconnects a plurality of water-related facilities, the database 23, the operation plan creation server 24, the Internet browsing terminal 25, and the management server 26. The communication network 22 is an Internet line, an intranet line, etc., but the power transmission and distribution network 21 may also be used. The database 23, the operation plan creation server 24, the Internet browsing terminal 25, and the management server 26 may be integrated in part or in whole.

The database 23 is an example of a storage means, and is configured by an information processing device such as a workstation. The database 23 is capable of writing and reading electronic information via the communication network 22. The database 23 stores information on the water-related facilities and the power transmission/distribution/communication/piping networks that configure the virtual resource plant 1 via the communication network 22 at a predetermined cycle or at any timing. The database 23 stores the following operation-related data, including operation data for multiple water-related facilities, as an example.
・Purified water production capacity of purified water production facilities ・Purified water storage capacity of purified water storage facilities (storage capacity of purified water storage facilities - current storage capacity of purified water storage facilities)
- Purified water supply capacity of purified water supply facilities - Time fluctuation of purified water demand at water treatment facilities - Wastewater volume discharged from each water treatment facility - Wastewater treatment capacity of wastewater treatment facilities - Wastewater storage capacity of wastewater storage facilities (storage capacity of wastewater storage facilities - current storage volume of wastewater storage facilities)
・Water quality required by each water treatment facility ・Water quality of sewage discharged from each water treatment facility ・Water level and water volume of intake reservoirs, distribution reservoirs, etc. ・Electricity costs and hourly fluctuations in electricity rates ・Hourly fluctuations in electricity supply and demand, electricity supply and demand situation ・Type of electric energy ・Adjustable power capacity ・Operating status of each water treatment facility (including operating hours, regular inspection and repair information, etc.)
・Charging and discharging status of the storage facility (SOC)
- General information that affects the operation of each water treatment facility (weather, political, economic, social, etc. information, including current conditions and future predictions)
- Contents of the contract regarding virtual power supply (power saving) (power saving period, amount of power saving, number of power saving requests (times/year), etc.)

The operation plan creation server 24 is an example of an operation plan creation means, and is composed of an information processing device such as a workstation, and an artificial intelligence such as XAI. The operation plan creation server 24 creates operation plans for each of areas A to C (virtual resource supply facilities) based on instructions from the power company.

Here, the operation plan created by the operation plan creation server 24 (operation plan creation means) will be described in more detail. First, the power company transmits a command to request a specific virtual resource from the management server 26 (specific virtual resource request means) to the operation plan creation server 24. A specific virtual resource is a virtual resource for which a requested supply time and a requested resource amount during the requested supply time are specified, and more specifically, a power saving request time period and a requested power saving amount during the power saving request time period. The requested power saving amount may be constant or may vary within the power saving request time period. Either or both of the power saving request time and the requested power saving amount may be fixed. For example, the power saving request time period may be 14:00 to 16:00 on weekdays, and the requested power saving amount may always be 150 kW.

The management server 26 comprises the following means, which are realized by computer applications and communication functions.
A prediction means for predicting how much resource (electricity) will be in short supply in a certain time period based on the power supply and demand situation, temperature prediction, etc. stored in the database 23. A specific virtual resource requirement determination means for determining how much resource to request as a specific virtual resource in a certain time period based on the prediction result of the prediction means (this requirement is called a specific virtual resource requirement). A means for transmitting the specific virtual resource requirement to the operation plan creation server 24.

The specific virtual resource requirements can be automatically created by the specific virtual resource requirements determination means using AI or the like based on the prediction results of the prediction means. The specific virtual resource requirements can also be determined by the operator. In this case, it is preferable that the specific virtual resource requirements determination means has a function for displaying data to assist the operator in making decisions, a function for accepting input from the operator, etc.

The operation plan creation server 24 creates an operation plan so that two or more virtual resource supply facilities among the multiple virtual resource supply facilities (areas A to C) share the supply of a specific virtual resource. A specific example of the operation plan will be explained in the operation example.

When the operation plan creation server 24 receives a specific virtual resource request, it divides the requested supply time of the specific virtual resource into multiple requested supply times (hereinafter referred to as segmented requested supply times). Next, the operation plan creation server 24 queries each area management unit 12A to 12C via the communication network 22 (transmission means) about the amount of resources that can be supplied for each segmented requested supply time (hereinafter referred to as segmented supplyable amount). The segmented supplyable amount is the amount of virtual resource that can be continuously supplied (power saving amount) during the corresponding segmented requested supply time. The operation plan creation server 24 refers to the contract information registered in the database 23 and excludes virtual resource supply facilities for which power saving requests cannot be made.

Each area management unit 12A to 12C monitors the water demand registered in the database 23, the water level of the intake reservoir, the water distribution reservoir, etc. (the amount of water and the water level that can be operated without problems even if the water-related equipment is stopped or the amount of discharge is suppressed), the operating status of the water-related equipment, etc., and is in a state where it is possible to grasp how much power can actually be saved. In response to an inquiry from the operation plan creation server 24, each area management unit 12A to 12C extracts water-related equipment that can save power, accumulates the power that each water-related equipment can save for each section request supply time, and calculates the section supplyable amount for each section request supply time. Each area management unit 12A to 12C transmits the section supplyable amount for each section request supply time to the operation plan creation server 24 via the communication network 22 (transmission means). The section supplyable amount may be lower than the requested resource amount for each section request supply time, may be higher than it, or may be zero. The operation plan creation server 24 creates an operation plan by combining the section supplyable amount for each section request supply time transmitted from each area management unit 12A to 12C so as to satisfy the specific virtual resource request. Operation plans can also be created using AI.

Each area management unit 12A-12C may also calculate the sectional supplyable amount for each type of electric energy. Electric energy can be classified into green energy (energy that does not emit greenhouse gases), gray energy (energy that emits greenhouse gases), and blue energy (energy that reduces greenhouse gas emissions by recovering and using greenhouse gases emitted in the manufacturing process of gray energy), and the database 23 stores the type of electric energy used by each water-related facility. If there is a surplus in the sectional supplyable amount for each sectional requested supply time transmitted from each area management unit 12A-12C, the operation plan creation server 24 can create an operation plan by combining the sectional supplyable amount for each sectional requested supply time in the order of priority of green energy, blue energy, and gray energy.

The operation plan created by the operation plan creation server 24 is transmitted to the area management units 12A-12C of the areas incorporated in the operation plan. Based on the operation plan, each area management unit 12A-12C controls the water-related facilities under its management so as to supply the allocated virtual resources (save power) during the allocated division request supply time. The actual control may be performed automatically by each area management unit 12A-12C or manually by an operator. Alternatively, the operation plan creation server 24 may transmit the operation plan to the management server 26, and the management server 26 may control the area management units 12A-12C.

(Example of operation)
An operation example is shown below. Assume that a specific virtual resource request is issued at 10:00 on a certain day of a certain month. The specific virtual resource request is for 150 kW continuously during the time period from 13:00 to 16:00 on the same day. As described above, a specific virtual resource request may request a certain amount of virtual resources over a certain period of time. The operation plan creation server 24 sets the sectional request supply times to 13:00 to 14:00, 14:00 to 15:00, and 15:00 to 16:00. The requested resource amount during each sectional request supply time is 150 kW.

Table 1 shows the sectional supply capacity for each sectional requested supply time in each of areas A to C. Area A can supply 150 kW from 13:00 to 14:00, area B can supply 150 kW from 14:00 to 15:00, and area C can supply 150 kW from 15:00 to 16:00. Next, the operation plan creation server 24 determines whether or not a specific virtual resource request is satisfied by combining multiple pairs of sectional requested supply times and sectional supply capacity sent from each of areas A to C. If the operation plan creation server 24 determines that the request is satisfied, it creates an operation plan by combining the pairs of sectional requested supply times and sectional supply capacity. That is, the operation plan creation server 24 creates an operation plan in which area A supplies 150 kW from 13:00 to 14:00, area B supplies 150 kW from 14:00 to 15:00, and area C supplies 150 kW from 15:00 to 16:00.

Tables 2 and 3 show other patterns of the sectional supply possible amount for each sectional requested supply time in each of areas A to C. In the example of Table 2, the operation plan creation server 24 creates an operation plan in which areas A, B, and C each supply 50 kW from 13:00 to 14:00, areas A, B, and C each supply 50 kW from 14:00 to 15:00, and areas A, B, and C each supply 50 kW from 15:00 to 16:00. In the example of Table 3, the operation plan creation server 24 creates an operation plan in which areas A, B, and C each supply 50 kW from 13:00 to 14:00, area C supplies 150 kW from 14:00 to 15:00, area A supplies 100 kW and area B supplies 50 kW from 15:00 to 16:00.

In each operation example, each area alone cannot satisfy the specific virtual resource requirements, but by implementing linked operation (combination, switching, etc.) of areas A to C, the specific virtual resource requirements can be satisfied and the electrical energy obtained by power saving in each area can be effectively utilized. Therefore, according to this embodiment, a power adjustment function such as leveling the power load, adjusting power demand during power shortages, and compensating for a shortage in the supply of renewable energy, and a water resource adjustment function such as reducing the load on water-related facilities and making effective use and sharing of water, are realized, and effective power and water saving is possible through the synergistic effect of both functions. In addition, this embodiment also contributes to the provision of emergency water infrastructure, the construction of an efficient distributed sewerage and drainage system, and low carbonization.

In the above operation example, a specific virtual resource request is issued at 10:00, so a preparation time (3 hours) is given until the requested supply time. If the specific virtual resource request can be satisfied by operating the water-related equipment at full capacity during this preparation time, the water-related equipment can be operated at full capacity during the preparation time to respond to the specific virtual resource request. In this way, after a specific virtual resource request is issued, preparations for power saving may be actively implemented. In other words, the operation plan may include an operation plan for responding to the specific virtual resource request during the preparation time until the requested supply time.

In the operation example, the requested supply time of a specific virtual resource is divided into multiple divided requested supply times, but each area management unit 12A to 12C may transmit the amount of resources that can be supplied within the requested supply time and the available supply time to the operation plan creation server 24. For example, within the requested supply time (13:00 to 16:00), area A can supply 100 kW between 13:00 and 14:30, area B can supply 50 kW between 13:00 and 16:00, and area C can supply 125 kW between 14:00 and 16:00. In this case, for example, an operation plan can be created in which area A supplies 100 kW between 13:00 and 14:30, area B supplies 50 kW between 13:00 and 16:00, and area C supplies 100 kW between 14:30 and 16:00.

In the above embodiment, each virtual resource supply facility is an area having a plurality of virtual resource supply facilities (water-related facilities), but each virtual resource supply facility may be composed of one virtual resource supply facility (water-related facility). That is, in the above embodiment, a specific virtual resource request is handled on an area basis, but it can also be handled on a virtual resource supply facility basis (water-related facility basis). In addition, the virtual resource may be a fluid resource such as water, gas, heat (hot water, cold water, etc.), hydrogen, ammonia, CO ₂ , etc. In the case where the virtual resource is a fluid resource other than water, "water supply" can be replaced with "transport", "purified water" can be replaced with "purified fluid", "drainage" can be replaced with "discharge", etc. In addition, in the case of ammonia, for example, a "purified water production facility" can be replaced with an "ammonia production facility", a "water treatment facility" can be replaced with an "ammonia use facility", a "purified water storage facility" can be replaced with an "ammonia storage facility", a "sewage wastewater treatment facility" can be replaced with an "ammonia treatment facility", and a "sewage wastewater storage facility" can be replaced with a "used ammonia storage facility". In the case where multiple fluid resources can be used in combination, and an instruction from the management server 26 or information on which resource should be used preferentially is included in the database 23, the operation plan creation server 24 can create an operation plan taking that information into consideration. This is the same idea as prioritizing green energy, blue energy, and gray energy in the case of electrical energy.

(Examples of application)
An example in which the above-described embodiment is applied to a specific example will be described.
[Sub-area A]
[Throughput]
In the case of individual operation of each facility, the water treatment facilities 2A, 2B, and 2C each perform optimal operation (treatment) and therefore each operates at 100%. That is, the respective treatment volumes are 100 m ³ /h, 200 m ³ /h, and 300 m ³ /h. In addition, the treatment volumes of the purified water production facility 3A and the sewage treatment facility 4A are both 2,000 m ³ /h, so the total treatment volume in area A at this time is 100 + 200 + 300 + 2,000 + 2,000 = 4,600 m ³ /h. On the other hand, in the case of the operation plan of this application example, the operation status of each facility is linked, and the load that can be operated with the operation plan of this application example is calculated from the operating status, required water volume, water quality, water treatment capacity, etc. of each facility. That is, the purified water production equipment 3A, the water treatment equipment 2A, 2B, 2C, and the sewage treatment equipment 4A are aware of each other's status and work together, being M: medium (75% operation), H: high (100% operation), M: medium (75% operation), L: low (50% operation), and M: medium (75% operation). The water treatment equipment 2A is operating at 100% compared to 100 ^m3 /h when operated individually, so the operation plan for this application example also has a treatment volume of 100 ^m3 /h, but since 100 ^m3 /h of water is lent from the purified water storage equipment 5A, the treatment volume is 0 ^m3 /h. Based on the same concept, the treatment volumes of the water treatment equipment 2B and 2C are 150 ^m3 /h and 150 ^m3 /h, respectively. Therefore, the water treatment plants 2A, 2B, and 2C can reduce their treatment load by 100-0= ^100m3 /h, 200-150= ^50m3 /h, and 300-150= ^150m3 /h, respectively, compared to when they are operated individually. Also, the purified water production plant 3A only needs to be operated at 75% of the capacity when operated individually ( ^2,000m3 /h), so the treatment volume is ^1,500m3 /h, but because water treatment plants 2A, 2B, and 2C can save water by ^100m3 /h, ^50m3 /h, and ^150m3 /h, respectively, a treatment volume of 1,500-100-50-150= ^1,200m3 /h (purified water production) will suffice. Therefore, the water treatment equipment 2A, 2B, and 2C can reduce the treatment load by 100-0=100m ³ /h, 200-150=50m ³ /h, and 300-150=150m ³ /h, respectively, compared to when they are operated individually. Also, the water treatment equipment 2A receives 100m ³ /h of water from the purified water storage equipment 5A, but the operation plan of this application example also generates a wastewater volume of 100m ³ /h. By the same reasoning, the wastewater volume of the water treatment equipment 2B is 150m ³ /h. The water treatment equipment 2C is operated at 50% of the 300m ³ /h when operated individually, so the operation plan of this application example generates a wastewater volume of 150m ³ /h, but since it is sent to the water treatment equipment 2D in area B, it is not supplied to the sewage treatment equipment 4A. Therefore, compared to when the water treatment plants 2A, 2B, and 2C are operated individually, the wastewater treatment load of the wastewater treatment plant 4A can be reduced by 100-100= ⁰ m3/h, 200-150= ⁵⁰ m3/h, and 300-0=300 ^m3 /h, respectively. Also, the sewage treatment plant 4A only needs to be operated at 75% of the rate of operation (2,000 ^m3 /h) when operated individually, so the treatment volume is 1,500 ^m3 /h, but since the sewage treatment load can be reduced by 0 ^m3 /h, 50 ^m3 /h, and 300 ^m3 /h in the water treatment plants 2A, 2B, and 2C, respectively, the sewage treatment volume will be 1,500-0-50-300=1,150 ^m3 /h.

Therefore, the treatment volume of the entire equipment in Area A (purified water production equipment 3A, water treatment equipment 2A, 2B, 2C, sewage treatment equipment 4A, purified water storage equipment 5A) in the case of the operation plan of this application example is 1,200 + 0 + 150 + 150 + 1,150 + 100 = 2,750 ^m3 /h, so the treatment volume in Area A in the operation plan of this application example can be reduced by 4,600 - 2,750 = 1,850 ^m3 /h compared to when operated individually.

[power consumption]
Assuming that the power consumption is 50% of the treatment volume, the power consumption of the purified water production equipment 3A, the water treatment equipment 2A, 2B, 2C, and the sewage treatment equipment 4A in the case of individual operation is 1,000, 50, 100, 150, and 1,000 kWh, respectively. On the other hand, the power consumption of the purified water production equipment 3A, the water treatment equipment 2A, 2B, 2C, and the sewage treatment equipment 4A in the case of the operation plan of this application example is 600 (1,200÷2), 0 (because the treatment volume = 0 ^m3 /h), 75 (150÷2), 75 (150÷2), 575 (1,150÷2), and 25 (power consumption to receive water from the purified water storage equipment 5A) kWh, respectively. Therefore, while the total power consumption in the case of individual operation is 1,000 + 50 + 100 + 150 + 1,000 = 2,300 kWh, the total power consumption in the case of the operation plan of this application example is 600 + 0 + 75 + 75 + 575 + 25 = 1,350 kWh, which means a savings of 2,300 - 1,350 = 950 kWh.

[Areas B and C]
Similarly, the treatment volume of the operation plan for this application example for all the facilities in Area B (purified water production facility 3B, water treatment facilities 2D, 2E, 2F, sewage treatment facility 4B, purified water storage facility 5B) is 350 + 0 + 0 + 50 + 450 + 200 = 1,050 ^m3 /h, which is a reduction of 1,650 ^m3 /h compared to individual operation (2,700 ^m3 /h), and power consumption is saved by 825 kWh. The treatment volume of all the equipment in Area C (purified water production equipment 3C, water treatment equipment 2G, 2H, 2I, sewage treatment equipment 4C, sewage storage equipment 6) in the operation plan of this application example is 1,250 + 350 + 100 + 300 + 950 + 200 = 3,150 ^m3 /h, which is a reduction of 3,850 ^m3 /h compared to individual operation (7,000 ^m3 /h), and power consumption was saved by 2,025 kWh. From the above, the total treatment volume of Areas A to C was reduced by approximately 51% compared to individual operation (14,300 ^m3 /h), and the total power consumption of Areas A to C was reduced by approximately 53% compared to individual operation (7,150 kWh).
Furthermore, in cases where a single facility/area is unable to meet the requirements of the capacity market (activation command power source) (for example, regulated power capacity: 100 kW or more, continuous response time: 3 hours), such cases can be handled by combining and switching multiple facilities/areas in accordance with the present invention.
