Embodiment 1

In this embodiment, the power consumption attribute of the power consumer and the power cost attribute and the simulation period defined by the power supply type are acquired, and the power consumption attribute and the power supply type of the consumer are used for each of the plurality of power supply types. The power cost simulation calculation formula, which is a calculation formula for simulating the power cost for each power supply type in time series according to the specified power cost attribute, is held, and the acquired power consumption attribute is held. Provided is a power cost simulation device configured to select the power supply type having the lowest power cost among a plurality of power supply types in time series in the simulation period based on the power cost simulation calculation formula. ..

FIG. 16 is a diagram showing an overall image of the present embodiment. As an example, the electric power cost simulation device has acquired "electric power cost attributes" from each of the four electric power supply companies of Pacific Electric Power, Tokai Electric Power, Nippon Electric Power, and Daiwa Electric Power, and the acquired "electric power consumption attributes" of the ABC coffee chain. Using the acquired "simulation period", the "selection result within the simulation period of the power supply type with the lowest power cost" is calculated based on the "power cost simulation calculation formula".

"Electricity supply type" means an electric power supply service provided by an electric power company or / and an individual electric power company. The electric power company means "a retail electric power company, a general power transmission and distribution business, a power transmission business, a specific power transmission and distribution business, and a power generation business", and a combination thereof may be included in the power supply type. For example, a combination of a power selling company and a power transmission company. In 2015, the Electricity Business Act was partially amended by the "Act No. 47 of June 24, 2007", in line with the full liberalization of electricity retailing from April 1, 2016. , The revised Electricity Business Law came into effect on the same day, but the electric power companies specified by the old name before this amendment, "general electric power companies, wholesale electric power companies, specified electric power companies and specified scale electricity""Businessoperator" is applicable in Japan. It also includes businesses that have come to be called "new power", which is a business that retails to consumers with contract power of 50 kW or more by receiving special high voltage and high voltage through transmission lines managed by general electric power companies.
FIG. 19 is a diagram showing an example of selection of an “available power supply type” as an option among many power supply companies. Candidates include "Pacific Electric Power", "Tokai Electric Power", "Nippon Denryoku", "Yamato Electric Power", "Nara Electric Power", and "Okinawa Electric Power". "Tokai Electric Power""NipponDenryoku""Yamato Electric Power" is selected. The "power supply type with the lowest power cost" in the selection unit described later is performed within the range of the selected power supply type.
In the specific example in the explanation using the following figure, as a virtual company, "Pacific Electric Power", "Tokai Electric Power", "Nippon Denryoku", "Yamato Electric Power" are used as virtual companies, and "ABC Coffee Chain" is used as an electric power consumer. I will explain to.

Hereinafter, the power cost simulation device in the present embodiment will be described in order with respect to the functional configuration, the hardware configuration, and the flow of processing.

<Functional configuration>
FIG. 1 is a diagram showing a functional configuration of the power cost simulation device according to the present embodiment. The power cost simulation device in the present embodiment includes a power consumption attribute acquisition unit (0101), a power cost attribute acquisition unit (0102), a simulation period acquisition unit (0103), a power cost simulation calculation formula holding unit (0104), and a selection unit ( 0105). Hereinafter, the functional configuration will be specifically described with respect to the contents of each function.

The "power consumption attribute acquisition unit" has a function of acquiring the power consumption attribute of a power consumer. The "power consumption attribute" indicates a pattern of power consumption in time series. The time series includes, for example, consumption patterns such as year, month, and week. The "consumer" may be a specific existing consumer, a representative and virtual consumer of the assumed industry, or a virtual consumer who is not particularly conscious of the industry itself. It may be. In other words, the consumer is the consumer of electricity.
The power consumption attribute acquisition unit may be selected from a plurality of patterns of the power consumption attribute prepared in advance, or is a hint of the power consumption attribute prepared in advance, and the power consumption attribute is filled in by filling in the blanks. It may be something that can be obtained. Alternatively, this fill-in-the-blank formula (which may be text) may be selected first, and then fill-in-the-blanks may be configured to acquire the power consumption attribute. Filling in the blanks may be configured to be performed by selecting a pull-down menu.

FIG. 20 is a diagram showing an example of power consumption attributes. The power consumption attribute is information indicating the power consumption tendency of a specific power consumer. For example, it can be derived from the actual power consumption of electric power consumers in the past one year or the past five years. Alternatively, it can be derived based on the past power consumption performance of a group consisting of a plurality of power consumers who can assume that the power consumption propensity is close. Alternatively, it is designed based on the assumption of what kind of power consumption tendency a virtual power consumer would show based on the past experience of the designer and administrator of this device, rather than based on actual results. Power consumption tendency. This virtual electric power consumer includes the industry classification to which the electric power consumer belongs (for example, Japan Standard Industrial Classification, industry classification appropriately designed by the designer) and industry classification (GICS industry classification, industry classification appropriately designed by the designer). , It may be prepared in advance according to the business scale of the electric power consumer. The power consumption attribute is a power consumption attribute applied during the simulation period described later. That is, the power consumption attribute is a value obtained as a function with the simulation period described later as the time axis.
For example, "maximum power consumption peak time zone (demand period)""(average) power consumption (by demand period)""maximum power consumption (by demand period)""contract power supply type""power consumption change tendency (increase rate)" , Decrease rate) "" Industry classification to which electricity consumers belong "" Information indicating the size of the company (annual sales, number of employees, market value in the case of listed companies) "" Electric power consumption ratio by device that consumes electricity "" Examples include "power consumption area (region, address)" and "power saving history of power consumers (power saving forecast)".

For the input of these power consumption attributes, it is conceivable to prepare candidates in advance and put them in a pull-down format.

FIG. 18 is a diagram showing an example of a screen when the power consumption attribute is input in a pull-down format. The company name of the target electric power consumer is input as "ABC coffee chain", and then the target period "Monday-Monday" can be input. On top of that, the items listed in FIG. 17 can be selected, and by selecting a specific item and then selecting it from the pull-down menu, the input can be completed automatically. By doing so, it is possible to prevent the input contents from spreading innumerably.

Further, the power consumption attribute acquisition unit is a basic equipment operating amount holding means for holding the basic equipment operating amount which is the equipment operating amount constituting the basic power consumption attribute in the unit time length unit in the simulation period, and the basic equipment operating amount holding means in the simulation period. A trial equipment operation amount acquisition means for acquiring a test equipment operation amount, which is a trial equipment operation amount in a unit time length unit, and a trial power consumption attribute for generating a power consumption attribute including the test equipment operation amount. It may have a generation means. In this case, the unit time length may be one or more of 30 minutes from the hour, a natural number multiple of 30 minutes from the hour, and 24 hours from the hour. good. Further, the test equipment operating amount acquisition means may have a replacement device that replaces the equipment operating amount of a certain unit time length with the equipment operating amount of another unit time length.
It is preferable that the experimental equipment operating amount is configured so as to be obtained by editing the held basic equipment operating amount. There is an effect that it is possible to obtain from the selection result of the selection unit what kind of power supply type selection is advantageous when the basic equipment operation amount is changed. Furthermore, it is possible to simulate the power cost based on this selection result, and it is possible to know how the cost changes when the basic equipment operating amount is changed. Furthermore, starting from one basic equipment operation amount, multiple trial equipment operation amounts are acquired, and the selection results in the selection section are compared for each of these, and the cost simulation results are compared. You can see the difference in the virtual operation plan. Furthermore, on top of this, it will be possible to compare the results of selecting different power supply types for the same period of the simulation period. The electric power cost attribute may be configured to include, for example, CO2 emission cost and carbon tax amount in addition to the electric power cost. The carbon tax is generally included in the electricity cost when it is levied on the electricity supplier, but by explicitly extracting and showing the carbon tax part, it is used as an index to be recognized as a barometer of socially responsible investment. You can also do it.

The "power cost attribute acquisition unit" has a function of acquiring the power cost attribute for each power supply type. The "electric power cost attribute" is an attribute related to the so-called electric power supply price, and what kind of condition, what kind of rule, what kind of price is set for the electric power consumer, or what kind of price is set. Information that indicates whether there is a tendency. For example, when the power supply capacity of the whole country or a specific area (for example, eastern Japan, western Japan, Okinawa, Hokkaido, the west coast, the east coast in the case of the United States, etc.) is exhausted, or the power supply of the whole country or a specific area. It is information showing the relationship between the power supply conditions and the power supply price at that time, such as what price is set when there is a lot of spare capacity. Power supply conditions include season, month, day, time zone, region, supply amount, power generation cost, and power supply price determination policy. For each power supply type, it may be an average value of past actual results, the latest actual results, or an estimated cost attribute based on past actual results, not based on actual values. For example, the electric power cost attribute in the simulation period described later may be predicted based on the future forecast trend of the crude oil price, the future forecast trend of the exchange rate, and the past actual value, and the person may be another person. The power cost attribute is acquired as it should be applied during the simulation period described below. Further, when predicting the power cost attribute as described above, the power cost attribute prediction unit may be provided. Then, the power cost attribute prediction unit holds a power cost attribute prediction value calculation rule for calculating the predicted value of the power cost attribute by inputting a plurality of variables into a predetermined calculation formula, and is predicted or actually predicted. The power cost attribute can be configured to be obtained as a predicted value by entering the variable of. Since the power cost attribute is the power cost attribute of the simulation period as described above, it is a value obtained as a function of the time axis of the simulation period. The power cost attribute is defined corresponding to the smallest unit that constitutes the simulation period.
The smallest unit of the simulation period is usually the demand period, which consists of a set of multiple demand periods. That is, the beginning and end of the simulation period are the beginning and end of the demand period, and the end is also the end of the demand period. Therefore, in this case, the power cost attribute is determined for each demand period.
The "demand period" is the period used to determine the basic electricity rate, and in Japan, it is midnight every hour (1 o'clock, 2 o'clock, 3 o'clock, 4 o'clock, 5 o'clock, 6 o'clock, 7 o'clock. Hours, 9:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00, 17:00, 18:00, 19:00, 20:00, 21:00, 22:00, 23:00, 24:00 ( The 30 minutes from 0 o'clock)) is the 1-demand period, and the 30 minutes until the next hour is the 1-demand period.

FIG. 13 is a diagram showing an example of electric power cost attributes for each electric power supplier in relation to electric power consumers. For example, "basic charge / basic charge history", "electricity charge / electricity charge history", "fuel adjustment cost / fuel adjustment cost history" ("fuel adjustment cost" means that fuel cost is the economic situation (exchange rate and crude oil price). ) Is greatly affected, and in order to clarify the results of improving the management efficiency of electric power companies, fluctuations in fuel costs are quickly reflected in electricity prices.) "History of fluctuations in costs per unit power (single) Annual results or multi-year average) ”“ Fluctuations in cost per unit power received due to fluctuations in exchange rates ”“ Changes in costs per unit power received due to fluctuations in crude oil and other fuel prices ”“ Changes in costs per unit power received due to fluctuations in customs rates "Fluctuation of cost" and "Fluctuation of cost per unit power received due to fluctuation of shipping fee from the power plant of the supplier".

FIG. 22 is a diagram showing specific electric power cost attributes of four companies, Pacific Electric Power, Tokai Electric Power, Nippon Denryoku, and Yamato Electric Power. Pacific Electric Power has the characteristic of being cheaper (electric power cost attribute) for large consumers during the daytime during the New Year and Obon seasons. Tokai Electric Power has the characteristic (electric power cost attribute) that it supplies electric power at a certain discount throughout the year. Nippon Denryoku has the characteristic that the basic charge is low, but the electricity charge is relatively high (electric power cost attribute). Daiwa Electric Power has the characteristic (electric power cost attribute) that it is by far the cheapest charge before and after the settlement month (December, June). In this way, there is a power rate plan unique to the power supply company, and each has its own characteristics. For example, in the case of Nippon Denryoku, it is advantageous for households and small companies, but it is disadvantageous for companies that consume a large amount of electricity. Moreover, even for households and small companies, the fact is that the advantageous (low cost) power supply company changes depending on the season.

The "simulation period acquisition unit" has a function of acquiring a simulation period, which is a simulation period described later. The smallest unit of the simulation period is usually the demand period, which consists of a set of multiple demand periods. That is, the beginning and end of the simulation period are the beginning and end of the demand period, and the end is also the end of the demand period.
The "demand period" is the period used to determine the basic electricity rate, and in Japan, it is midnight every hour (1 o'clock, 2 o'clock, 3 o'clock, 4 o'clock, 5 o'clock, 6 o'clock, 7 o'clock. Hours, 9:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00, 17:00, 18:00, 19:00, 20:00, 21:00, 22:00, 23:00, 24:00 ( It means 30 minutes from 0 o'clock)) and then 30 minutes until the next hour.
"Electricity charges" are usually set as follows.
"Electricity charge" = "Basic charge (fixed charge)" + "Electric energy charge (metered charge)" + "Renewable energy power generation promotion levy" (Electricity charge includes a considerable amount such as consumption tax)
"Basic charge" = "charge unit price" x "contract power (kW)" x "(185-power factor) / 100"
"Electric energy charge" = "Electric energy charge unit price (yen / kWh)" x "Electric energy consumption (kWh)" ± "Fuel cost adjustment amount". Here, the "fuel cost adjustment amount" is an amount for adjusting the electricity price according to the price fluctuation of the fuel [crude oil, LNG <liquefied natural gas>, coal]. The fuel cost adjustment amount is calculated by multiplying the fuel cost adjustment unit price (yen / kWh) by the amount of power used (kWh).
Next, a method of determining the contract power will be described. As for the method of determining the "contract power (kW)", for example, in the case of a power consumer having a high voltage of less than 500 kW, the monthly contract power (kW) is determined by an actual amount system based on the measured value of the meter. The "actual energy system" is an electronic watt-hour meter with a built-in maximum demand wattmeter, which measures the average amount of electricity consumed every 30 minutes, and the largest value in a month is the maximum demand value / maximum. It is the demand power. The contract power is the largest value among the maximum demand power of each month in the past year including this month.
As mentioned above, a typical example of the simulation period is one year, and if you are going to conclude a power supply contract with a new power supplier, it is convenient to set it to one year from the assumed contract start date. be. This is because it is possible to see how much power costs can be reduced in the next year by switching to a new power supplier. A typical example of the new power supplier envisioned here is a power supplier (power supply) that always supplies power to the power consumer in chronological order at the lowest cost for each period throughout the year. It is one power supplier, etc. that promises to supply power at the same cost when switching (type). In other words, it is a power supplier that provides a power supply business model that enables virtual switching of power providers (power supply types) that cannot be performed frequently in reality. In other words, the power supplier has a rigid power charge system (“electricity charge” = “basic charge (fixed charge)” + “electric energy charge (metered charge)” + “promotion of renewable energy power generation” as described above. It does not adopt "levy").
In addition, the simulation period may be in minutes, in 1 hour, in 3 hours, in the morning / afternoon, or in days. It may be on a weekly basis, on a monthly basis, or on a yearly basis.

The "power cost simulation calculation formula holding unit" is the power consumption attribute of the consumer and the power cost attribute defined by the power supply type for each of the plurality of power supply types, and the power is generated in time series during the simulation period. It has a function to hold a power cost simulation calculation formula, which is a calculation formula for simulating the power cost for each supply type.
As a typical "power cost simulation formula", the value of the power consumption included in the power consumption attribute (for example, 1000kWh) and the power cost for each unit time (for example, demand unit period) of the simulation period. A process of multiplying the cost per unit power consumption included in the attribute (whether it is a monetary unit or another unit. For example, 10 yen / 1kWh) (for example, 1000kWh × (10 yen / 1kWh). ) = 10,000 yen).

The "selection unit" has the lowest power cost among a plurality of power supply types based on the acquired power consumption attribute, the acquired power cost attribute, and the held power cost simulation calculation formula. It has a function to select the power supply type in time series within the simulation period. The simulation period is typically one year, when the season goes around once. This is because the power consumption pattern usually has one cycle in one year.
The minimum period unit for selecting the power supply type is the demand period. Since the demand period is as described above, it can be designed to select the power supply type most frequently at 30-minute intervals. However, the present invention is not limited to this, and a period of 30 minutes, which is several times the natural number, can be selected as the time length during which the power supply type can be switched. A feature of this device is that it does not have to match the actual rules of switching power companies. Further, the switching period of the power supply type can be configured to select the switching period. In that case, it is conceivable to provide a switching period selection means in the selection unit.

FIG. 21 is a diagram showing an example of electric power costs (yen / kW) incurred for a specific monthly electric power consumer of four electric power supply companies based on the electric power consumption attribute of a specific electric power consumer. Here, the unit of the selection period in the time series is set to the unit of the month, and the simulation period is shown as an example of one year in which the season goes around once.
Pacific Electric Power has "23.0" in November, "21.5" in December, "21.5" in January, "22.5" in February, "23.5" in March, and 4 The month is "25.0", May is "23.5", June is "22.5", July is "21.0", August is "21.5", and September is "23. 5 ”and October are“ 25.0 ”.
Tokai Electric Power Co., Ltd. has "17.5" in November, "19.0" in December, "21.5" in January, "25.0" in February, "19.5" in March, and 4 The month is "17.0", May is "17.5", June is "18.5", July is "24.0", August is "25.5", and September is "20. "0" and October are "19.0".
Nippon Electric Power Co., Ltd. has "17.5" in November, "20.5" in December, "23.5" in January, "25.0" in February, "22.0" in March, and 4 The month is "22.5", May is "20.5", June is "18.5", July is "21.0", August is "23.0", and September is "22. "0" and October are "22.5".
Daiwa Electric Power has "15.0" in November, "20.0" in December, "22.5" in January, "20.5" in February, "21.0" in March, and 4 The month is "20.5", May is "19.5", June is "15.5", July is "18.0", August is "22.5", and September is "25. "5" and October are "23.5".
Assuming the above power costs, the power supply type with the lowest power cost is the part surrounding the numbers in the figure. Specifically, November is "15.0" (Daiwa Electric Power), December is "19.0" (Tokai Electric Power), January is "21.5" (Pacific Electric Power, Tokai Electric Power), and February is. "20.5" (Daiwa Electric Power), March "19.5" (Tokai Electric Power), April "17.0" (Tokai Electric Power), May "17.5" (Tokai Electric Power), 6 Month is "15.5" (Daiwa Electric Power), July is "18.0" (Daiwa Electric Power), August is "21.5" (Pacific Electric Power), September is "20.0" (Tokai Electric Power) In October, "19.0" (Tokai Electric Power) is the power supply type with the lowest power cost. In the selection unit, the supply type is selected.

FIG. 14 is a diagram showing an example of the selection contents in the selection unit as a graph. Here, too, the unit of the selection period in the time series is set to the unit of the month, and the simulation period is shown as an example of one year in which the season goes around once. The contents of each numerical value are as shown in Fig. 21, but when the graph shows the power cost on the vertical axis, the power supply type at the bottom is the power supply type with the lowest power cost. , The selected power supply type will be the lowest power supply type in each month.

FIG. 15 is a graph showing a comparison of power costs with the selected power supply type, taking as an example the case where the ABC coffee chain uses Pacific power. Since the selected power supply type is "the power supply type with the lowest power cost", the power cost will not be higher than that of Pacific Power. For example, in January and August, when the power cost of Pacific Power was the lowest among the four power supply companies, the power supply type (Pacific power) of the power cost was selected. On the other hand, in the months other than January and August, the power cost of companies other than Pacific Electric Power was the lowest, so the power supply type of the power company with the lowest price is selected. Therefore, for that month, it will be lower than the electricity cost of Pacific Electric Power. Therefore, simulations show that it will lead to a significant reduction in electricity costs for the ABC coffee chain throughout the year. In other words, if such a rate system can be presented to electric power consumers as a business model of a new electric power company, it will be possible to supply electric power to electric power consumers at an unprecedented low cost, so that electric power consumers will also have a large cost. It can be reduced and motivates the selection of the operator.

The above is the selection when the actual value is adopted as the cost attribute, but the power supply type that is judged to have the lowest power cost based on the power consumption attribute and the power cost attribute that does not directly adopt the actual value. May be configured to select. In other words, it is not the person who uses the past actual value of each power supply type as the power cost attribute, but the case where the power cost attribute predicted in the future for each power supply type is derived and used based on the past actual value and the like. Is. Specifically, if the "electric power consumption attribute" is a large consumer and the seasonal fluctuation is severe, the "electric power cost attribute" predicted in the future, which is the simulation period, selects the power supply type that is disadvantageous to the large consumer. In addition, the cheapest power supply type (power supply type with a low unit price of power cost when a large amount of power is consumed) is selected in consideration of the contents of seasonal fluctuations. In this case, for example, there may be a plurality of power supply types that are considered to be advantageous to large consumers. In such a case, the person who manages the invention device may decide which of the plurality to be selected, or the power consumer who requests the manager to perform the simulation may select. However, the device for invention may be configured to arbitrarily select using a random number or the like.
In addition, multiple scenarios with different selectivity for selecting which power supply type are prepared, the power consumer or the like is made to select the scenario, and the power supply type is selected according to the selected scenario. You can also do it. For this purpose, the power cost simulation device can be configured to include a scenario holding unit, a scenario selection receiving unit, and a scenario selection control unit that controls the selection unit according to the scenario. Furthermore, the power cost simulation device automatically selects all multiple scenarios in sequence and executes the selection while controlling the selection unit, and compares the execution results to compare the power cost most over the entire simulation period.

<Hardware configuration>
The hardware configuration of the power cost simulation device in this embodiment will be described with reference to the drawings.

FIG. 2 is a diagram showing a hardware configuration of the power cost simulation device according to the present embodiment. As shown in this figure, the computer is configured on the motherboard, such as a chipset (0210), a CPU (0201), a non-volatile memory (0203), a main memory (0204), various buses (0202a to 0202e), and a BIOS. (0207) It is composed of various interfaces (0205, 0206, 0208), a real-time clock (0209), and the like. These work in conjunction with operating systems, device drivers, and various programs. The various programs and various data constituting the present invention are configured to efficiently utilize these hardware resources to execute various processes.
<Chipset>
A "chipset" is a set of large-scale integrated circuits (LSIs) mounted on the motherboard of a computer and integrated with a communication function between an external bus of the CPU and a standard bus for connecting memories and peripheral devices, that is, a bridge function. .. There are cases where a two-chipset configuration is adopted and cases where a one-chipset configuration is adopted. A north bridge is provided on the side close to the CPU and main memory, and a south bridge is provided on the side of the interface with a relatively low-speed external I / O on the far side.
(Northbridge)
The north bridge includes a CPU interface, a memory controller, and a graphic interface. The CPU may be responsible for most of the functions of the conventional north bridge. The north bridge is connected to the memory slot of the main memory via a memory bus, and is connected to the graphic card slot of the graphic card by a high-speed graphic bus (AGP, PCI Express).
(Southbridge)
The south bridge is connected to a PCI interface (PCI slot) via a PCI bus, and is responsible for I / O functions and sound functions with an ATA (SATA) interface, a USB interface, an Ethernet interface, and the like. Incorporating circuits that support PS / 2 ports, floppy disk drives, serial ports, parallel ports, and ISA buses that do not require or do not require high-speed operation will hinder the speeding up of the chipset itself. Therefore, it may be separated from the chip of the south bridge and assigned to another LSI called a super I / O chip. A bus is used to connect the CPU (MPU) to peripheral devices and various control units. The buses are connected by a chipset. The memory bus used for connection with the main memory may adopt a channel structure instead of the memory bus in order to increase the speed. A serial bus or a parallel bus can be used as the bus. In the parallel bus, while the serial bus transfers data bit by bit, the original data itself or a plurality of bits cut out from the original data are grouped together and transmitted over a plurality of communication paths at the same time. A dedicated clock signal line is provided in parallel with the data line to synchronize data demodulation on the receiving side. It is also used as a bus that connects a CPU (chipset) and an external device, and includes GPIB, IDE / (parallel) ATA, SCSI, and PCI. Since there is a limit to the speedup, the data line may be a serial bus in the improved version of PCI Express or the improved serial ATA of parallel ATA.
<CPU>
The CPU reads, interprets, and executes instruction sequences called programs in the main memory in order, and outputs information consisting of signals to the main memory as well. The CPU functions as a center for performing calculations in the computer. The CPU is composed of a CPU core part that is the center of calculation and a peripheral part thereof, and has a register and a cache memory inside the CPU, an internal bus that connects the cache memory and the CPU core, a DMA controller, a timer, and a north bridge. The interface with the connection bus with is included. A plurality of CPU cores may be provided in one CPU (chip). Further, in addition to the CPU, processing may be performed by a graphic interface (GPU) or an FPU.
<Non-volatile memory>
(HDD)
The basic structure of a hard disk drive consists of a magnetic disk, a magnetic head, and an arm on which the magnetic head is mounted. The external interface can adopt SATA (ATA in the past). A sophisticated controller, such as SCSI, is used to support communication between hard disk drives. For example, when copying a file to another hard disk drive, the controller can read the sector and transfer it to another hard disk drive for writing. At this time, the memory of the host CPU is not accessed. Therefore, it is not necessary to increase the load on the CPU.
<Main memory>
The CPU directly accesses and executes various programs on the main memory. The main memory is a volatile memory and DRAM is used. The program on the main memory is expanded from the non-volatile memory onto the main memory in response to the program start command. After that, the CPU executes the program according to various execution instructions and execution procedures in the program.
<Operating system (OS)>
The operating system is used to manage the resources on the computer for the application to use, to manage various device drivers, and to manage the computer itself, which is the hardware. Small computers may use firmware as an operating system.
<BIOS>
The BIOS is the one that causes the CPU to execute the procedure for starting up the hardware of the computer and operating the operating system, and most typically, the hardware that the CPU first reads when receiving the start command of the computer. .. Here, the address of the operating system stored in the disk (nonvolatile memory) is described, and the operating system is sequentially expanded to the main memory by the BIOS expanded in the CPU and put into an operating state. The BIOS also has a check function for checking the presence or absence of various devices connected to the bus. The result of the check is saved in the main memory and made available by the operating system as appropriate. The BIOS may be configured to check an external device or the like.

The above is the same for other embodiments.

Further, the calculated power cost may be calculated by dividing the simulation period into a plurality of sub-periods and showing the result. In addition, the power cost is the power cost attribute used to calculate the power cost, the representative value of the power consumption attribute, or the one calculated by an example, and the resimulation is immediately shown by changing these values.

Of course, it may be output by voice. Furthermore, the post-selection power cost simulation results include not only costs such as monetary units, but also information for specifying the power supply type selected in each period of the simulation, and the reason why the power supply type was selected. Further, it may include a comparison with the case where another power supply type is selected. Furthermore, the circumstances assumed in performing the power cost simulation (forecast of fluctuations in fuel prices such as crude oil prices, forecasts of fluctuations in foreign exchange) may be included.

The definitions of "power supply type" and "power cost attribute" are the same as those described in the first embodiment.

<Functional configuration>
FIG. 24 is a diagram showing a functional configuration of the electric power charge calculation device according to the present embodiment. The power charge calculation device in the present embodiment includes a power consumption acquisition unit (2501), a power cost attribute acquisition unit (2502), a power charge calculation period acquisition period acquisition unit (2503), and a power cost calculation formula holding unit (2504). And has a selection unit (2505). Hereinafter, the functional configuration will be specifically described with respect to the contents of each function.

The "electric power consumption acquisition unit" has a function of acquiring the electric power consumption attribute of the electric power consumer. "Power consumption" indicates the actual power consumption in chronological order. The time series includes, for example, a year, a month, a week, and the like.

The “electric power cost attribute acquisition unit” is the same as the description of the first embodiment.

The "electric power charge calculation period acquisition unit" has a function of acquiring the electric power charge calculation period, which is the period for calculating the electric power charge. The smallest unit of the electricity charge calculation period is the demand period, which consists of a set of multiple demand periods. That is, the beginning and end of the simulation period are the beginning and end of the demand period, and the end is also the end of the demand period.

The "electric power cost calculation formula holding unit" is a time series for each of a plurality of electric power supply types in the electric power charge calculation period according to the electric power consumption amount of the consumer and the electric power cost attribute defined by the electric power supply type. It has a function of holding a power cost calculation formula, which is a formula for calculating the power cost for each power supply type.

The "selection unit" in this embodiment is the most power cost among a plurality of power supply types based on the acquired power consumption, the acquired power cost attribute, and the held power cost calculation calculation formula. It has a function to select the power supply type with a low cost in time series in the power charge calculation period.
The minimum period unit for selecting the power supply type is the demand period. Since the demand period is as described above, it can be designed to select the power supply type most frequently at 30-minute intervals. However, the present invention is not limited to this, and a period of 30 minutes, which is several times the natural number, can be selected as the time length during which the power supply type can be switched. A feature of this device is that it does not have to match the actual rules of switching power companies. Further, the switching period of the power supply type can be configured to select the switching period. In that case, it is conceivable to provide a switching period selection means in the selection unit.

Further, the electricity charge calculation device calculates the power charge for the electric power consumer within the electric power charge calculation period based on the selection result in the selection unit and the electric power supply attribute of the selected electric power supply type. It may have more parts.

As described above, the basic idea of selecting the lowest power supply type among a plurality of power supply types for each time series is the same as in the first embodiment, but the actual power consumption is not a simulation of prediction. It differs from the first embodiment in that the lowest power supply type is selected for each time series and the power charge is charged according to the amount of consumption.

The various programs and various data constituting the present invention are configured to efficiently utilize these hardware resources to execute various processes.

Here, the "main memory" reads a program for performing various processes to be executed by the "CPU", and at the same time, provides a work area which is also a work area of the program. In addition, a plurality of addresses are assigned to each of the "main memory" and the "HDD", and the program executed by the "CPU" exchanges data with each other by specifying and accessing the addresses. It is possible to perform processing. The programs stored in the "main memory" in the present embodiment are a power consumption acquisition program, a power cost attribute acquisition program, a power charge calculation period acquisition program, a power cost calculation calculation formula holding program, and a selection program. Further, the "main memory" and the "HDD" store power consumption, power cost attributes, power charge calculation period, power cost calculation calculation formula, and the like.

The "CPU" executes a power consumption acquisition program stored in the "main memory" to acquire power consumption from the user terminal device through the "network interface". Then, the power cost attribute acquisition program stored in the "main memory" is executed to acquire the power cost attribute from the user terminal device through the "network interface". Then, the power charge calculation period acquisition program stored in the "main memory" is executed to acquire the power charge calculation period. Then, the selection program stored in the "main memory" is executed, and the power cost is the lowest among the plurality of power supply types based on the acquired power consumption and the held power cost calculation formula. Select the power supply type to be in chronological order in the power charge calculation period.

<Processing flow>

As shown in FIG. 3, the power consumption acquisition step (S2701), the power cost attribute acquisition step (S2702), the power charge calculation period acquisition step (S2703), the power cost calculation calculation formula acquisition step (S2704), and the power cost calculation calculation formula acquisition step (S2704). It is a processing method including a selection step (S2705).

The "power consumption acquisition step" is a stage of acquiring the power consumption of a power consumer.

The “power cost attribute acquisition step” is a stage of acquiring the power cost attribute for each power supply type.

The "electric power charge calculation period acquisition step" is a stage of acquiring the electric power charge calculation period, which is the period for calculating the electric power charge.

The "power cost calculation calculation formula acquisition step" is a time series in the power charge calculation period according to the power consumption amount of the consumer and the power cost attribute defined by the power supply type for each of multiple power supply types. This is the stage of acquiring the power cost calculation formula, which is a formula for calculating the power cost for each power supply type.

The "selection step" is to calculate the power charge for the power supply type with the lowest power cost among multiple power supply types based on the acquired power consumption and the held power cost calculation formula. It is a stage to select in time series by period.
