Description

  TECHNICAL FIELD The present invention relates to a power supply service providing system that enables a power supplier to buy and sell a device usage right for controlling a power consumer side device between a power supplier that supplies purchased power and a power consumer. Is.

  Conventionally, it is common for a power supplier to request a power consumer to reduce power consumption, and to provide cost merit when control is performed on the consumer side. In the conventional incentive power load control system, a cost merit is given when control is performed on the customer side (see, for example, Patent Document 1). In this system, the incentive fee is paid only when the power consumer side reduces the power consumption.

  In addition, the conventional system generally performs on / off control for an adjustable device of an electric power consumer. In a conventional power load adjustment system, on / off control is performed on devices that can be adjusted by power consumers (see, for example, Patent Document 2). In this system, among the devices classified into the regulated load and the non-regulated load of the electric power consumer, the power supply circuit switching control of the device group classified as the regulated load is performed.

  FIG. 7 is a diagram showing a controllable power table in which the controllable power of the power consumer devices managed by the power supplier in the power supply service providing system according to Embodiment 1 of the present invention is summarized.

  As shown in FIG. 7, the power supplier S stores information on power that can be reduced by controlling the devices held by each power consumer. The control device 100 creates in advance a controllable power table as shown in FIG. 7 by collecting the controllable power of the devices 12, 22, 23, and 32 held by the power consumers C1, C2, and C3 in advance. Stored in the storage device.

  FIG. 8 is a diagram showing a usage right selection table showing how many yen is required for 1 kW control in the power supply service providing system according to Embodiment 1 of the present invention.

  The power supplier S calculates the unit price (yen / kW) of controllable power from the device usage right bid price table shown in FIG. 6 and the controllable power table shown in FIG. 7, as shown in FIG. carry out. For example, the control device 100 sets the bid price 10 yen for the device usage right of the device 12 of the power consumer C1 at the time 0:00 to 0:30, and the device of the power customer C1 at the same time 0:00 to 0:30. Dividing by 12 controllable power 30 kW, the unit price of controllable power 0.333 (yen / kW) is calculated. The control device 100 calculates the unit price of all devices every 30 minutes, creates a usage right selection table (yen / kW) as shown in FIG. 8, and stores it in the storage device.

  FIG. 9 is a diagram showing a target reduced power information table that is the power that the power supplier should secure (reduce) for performing control in the power supply service providing system according to Embodiment 1 of the present invention.

  As shown in FIG. 9, the power supplier S stores information on power that should be reduced in order to perform control in units of 30 minutes. The control device 100 pre-calculates the target reduction power that is the difference between the contract power contracted with the power company P and the maximum demand forecast value in units of 30 minutes, and summarizes the calculation results to obtain target reduction as shown in FIG. A power information table is created and stored in the storage device. The demand maximum predicted value is predicted and calculated by the control device 100 based on past data (power consumption), weather forecast including predicted temperature, and the like. For example, as shown in FIG. 9, in the unit of 30 minutes of time 0:00 to 0:30, there is a possibility that the total power consumption of all expected power consumers may exceed the contract power by 10 kW. This means that the control device 100 selects the right to use the device so as to reduce the possibility of exceeding 10 kW.

  The control device 100 collects the measured value of the total integrated watt-hour meter 101 through the communication line L2, and stores it in the storage device for prediction calculation of the maximum demand prediction value, billing, and the like. In addition, the control device 100 collects the measured values of the integrated watt-hour meters 11, 21, and 31 of each power consumer through the communication line L2, and stores them for billing the power usage fee to each power consumer. Accumulate in the device. Furthermore, the control apparatus 100 measures the power consumption of each apparatus 12, 22, 23, 32 of each electric power consumer through the communication line L2, and accumulate | stores it in a memory | storage device.

  FIG. 10 is a diagram showing a selected device information table of devices for which the power supplier has selected the device usage right purchase in the power supply service providing system according to Embodiment 1 of the present invention.

  The power supplier has a device usage right bid price table shown in FIG. 6, a controllable power table shown in FIG. 7, a usage right selection table showing unit price information of controllable power shown in FIG. As shown in FIG. 10, a device for which a device usage right is purchased is selected from the target reduced power information table that is the power to be reduced for performing the control shown in FIG. To store.

  The power supplier considers the combination of all device usage rights purchases per time unit, and purchases the device usage so that the total controllable power of the device usage rights is equal to or greater than the target reduced power and the purchase price is minimized. Decide the right. For example, in the unit of 30 minutes of time 0:00 to 0:30, when the device 22 having the controllable power amount equal to the target reduced power of 10 kW is purchased, the purchase price is minimized although the unit price is the second highest. . In addition, in the unit of 30 minutes from 10:00 to 10:30, the target reduction power is 50 kW, and the purchase price is minimized when the devices 12, 22, and 32 are purchased. If the number of combinations becomes very large and it takes too much time to consider all combinations, determine the combination that purchases the right to use the equipment in such a way that the solution within the allowable range is required from the minimum purchase price . FIG. 10 shows the result of purchasing the device usage right. As shown in FIG. 10, the control device 100 stores the devices 12, 22, and 32 for which the device usage right has been purchased in the corresponding column of the selected device information table. When a device usage right is purchased, a predetermined percentage (for example, 10% or 0%) of the purchase price is returned to the power consumer who sold the device usage right regardless of whether or not the device is actually controlled. To do. When the device is actually controlled, the remaining amount of the purchase amount is returned to the electric power consumer according to the control amount. In addition, when the total amount purchased is controlled, the total amount of money returned to the electric power consumer is the purchase amount of the device usage right.

  The process so far is the process up to the previous day. The control device 100 refers to the selected device information table of FIG. 10 on the day, and transmits the device purchased the device usage right for each power consumer and the information of the time unit to the terminals 10 to 30 through the communication line L3. On the other hand, when the terminals 10 to 30 receive information about the device that sold the device usage right and the unit of time, the terminal 10-30 distinguishes the column that sold the device usage right from the column that does not sell the device usage right trading display table shown in FIG. Display as you can. In FIG. 4, a portion where a point is written is a portion where the device usage right is sold, and a portion not drawn by hatching is a portion where the device usage right is not sold. The meaning of the portion indicated by one-side oblique lines or intersecting oblique lines will be described later.

  According to the first embodiment, the power supplier S purchases the device usage rights U1 to U4 from the power consumers C1, C2, and C3, and thereby the devices 12, 22, and 23 of the power consumers C1, C2, and C3. , 32 can be controlled, the power consumption of the devices 12, 22, 23, 32 can be suppressed, the contract power with the power company P can be kept low, and the fee paid to the power company P can be reduced. It is possible to implement a service that can be performed.

  FIG. 11 is a diagram showing a state in which the power supplier has purchased a device usage right from a power consumer in the power supply service providing system according to Embodiment 1 of the present invention.

  As shown in FIG. 11, the power supplier S purchases the device usage right U1 from the power consumer C1 and the device usage rights U2 and U3 from the power consumer C2. That is, as described above, the control device 100 creates a selected device information table by selecting a device for which a device usage right is purchased. Next, the control device 100 refers to the selected device information table and transmits information on the device usage right state including the device information and the time information in units of 30 minutes to the terminals 10 to 30. On the other hand, when receiving information on the status of the device usage right from the control device 100, the terminals 10 to 30 display the corresponding column of the device usage right trading display table shown in FIG. 4 in a display method according to the conditions of the device usage right. . Thus, the power consumer can recognize that the device usage right has been purchased by the power supplier S.

  FIG. 12 is a diagram showing a priority order table that defines priorities when the power supplier performs control on controllable devices in the power supply service providing system according to Embodiment 1 of the present invention. In FIG. 12, the power consumption suppression effect means the maximum amount that can suppress power consumption, and the reduction fee means the fee paid to the power consumer when the power amount described in the column of the power consumption suppression effect is suppressed.

  As shown in FIG. 12, the power supplier calculates the priority for performing control on the device from the power consumption suppression effect (kW) and the return charge (yen), and performs control on the device accordingly. The control device 100 calculates the priority order for performing control from the power consumption suppression effect and the return charge to the device every 30 minutes in the priority device information table of FIG. 10, creates a priority table, and stores it in the storage device. Store. As shown in FIG. 12, first, priority is given to a thing with a large power consumption suppression effect per unit reduction fee. In the example of FIG. 12, the priority order of the equipment 12 of the power consumer C1 that can control 0.8 kW of power with 0.1 yen is the first. Next, when the power consumption suppression effect per unit reduction fee is the same, priority is given to the larger controllable amount. Therefore, the priority order of the device 23 of the power consumer C2 is second.

  In the time zone in which the device usage right is purchased, the control device 100 has a predetermined time period (for example, 1 minute), and the difference between the measured value of the total integrated watt-hour meter 101 and the current measured value at the start time of the time unit. To calculate the power consumption in the predetermined time unit. In addition, a limit power consumption that is a power consumption at each time when contract power is consumed in a predetermined time unit is calculated. The marginal power consumption is calculated as consuming a certain amount of power in a predetermined period unit, so it is zero at the start time and becomes a straight line that becomes contract power at the end time. You may calculate limit power consumption so that it may become a broken line or a curve. If the limit power consumption at the end time is equal to the contract power, any calculation may be performed.

  When the power consumption becomes larger than the limit power consumption, it is predicted that the power consumption will exceed the contract power, and control is performed to suppress the power consumption of the device of the power consumer who purchased the device usage right. . Here, when it is predicted that the power consumption exceeds the contract power, the power consumption minus the contract power is referred to as excess power. The excess power, which is a value obtained by dividing the excess power amount by the remaining time in a predetermined time unit, is power that should reduce power consumption. The devices to be controlled are determined so that the total reducible power of the devices to be controlled is larger than the excess power. The device to be controlled is given priority to those with a low cost. In the case of controlling one device, the reduced power becomes excess power. When controlling multiple devices, the power that can be reduced is the reduced power except for the one with the lowest priority, and the sum of the reducible power of these devices minus the excess power has the lowest priority. Reduced power consumption of equipment. In addition, it is good also considering that the priority of all the apparatuses is the same, and what divided the excess electric power by the ratio of the electric energy which can be reduced is made into reduction electric power. FIG. 12 shows that when the excess power is 5.0 kW, 4.0 kW is suppressed by the device 12 of the power consumer C1, and 1.0 kW is suppressed by the device 22 of the power consumer C2. When the device is controlled, the limit power consumption after the time when it is predicted that the power consumption exceeds the contract power is recalculated. When it is predicted that the power consumption exceeds the contract power, the power consumption at that time is set as the limit power consumption, and a straight line connecting the points that are the contract power at the end of the period becomes the new limit power consumption.

  Power consumption fluctuates in time, and even if it is expected to exceed the contract power at the beginning of a given time unit, then the power consumption will naturally decrease, and the power consumption per time unit will be the contract power. There is a good chance that it will be less. As a result, in order to minimize the control of power consumer equipment that is no longer necessary, the power consumer equipment is not controlled until the predetermined period has elapsed since the start of the predetermined time unit, and the predetermined period has elapsed. Then, the device of the power consumer may be controlled. The predetermined period may be determined by time such as the first 5 minutes in a predetermined time unit of 30 minutes, or may be determined until the power consumption amount is, for example, 10% of the contract power.

  The predetermined period is appropriately determined in consideration of a trade-off between not generating unnecessary control and not exceeding contract power. If the predetermined period is large, the timing for controlling the power consumer's equipment will be delayed, and when controlling the power consumer's equipment, the amount of control will be large. There is a high possibility that a situation where the amount cannot be reduced below the contracted power will occur. When the predetermined period is small, the control timing is quickened, and the possibility that the amount of power consumption cannot be made equal to or less than the contracted power is reduced. Calculate the rate of change in power consumption, take into account the rate of change in addition to the amount of power consumption, predict the amount of power consumption at the end of a given time unit, and when the predicted value exceeds the contracted power consumption May be determined to exceed the contract power.

  When the control device 100 controls the power consumer device, the control device 100 notifies the power consumer terminal of the controlled device and the time unit. When the terminal receives the information that the device is controlled, the terminal displays the information so that the corresponding time unit of the corresponding device can be distinguished. In Fig.4 (a), the apparatus 23 is controlled by the electric power supplier by the time unit of 12: 0 to 13:30 of the apparatus 23 drawn with the hatching of the one side oblique line.

  According to the first embodiment, the power supplier S controls the devices 12, 22, and 23 of the power consumers C1 and C2 who have purchased the device usage rights U1 to U3 in order to suppress power consumption. By implementing and keeping the power consumption of the entire power consumer within a certain limit, it becomes possible to reduce the payment cost to the power company P and implement a service that can return the cost merit to the power consumer. .

  FIG. 13 is a diagram showing an operation when a power consumer buys back a device usage right from a power supplier in the power supply service providing system according to Embodiment 1 of the present invention.

  Even if the power consumer has transferred the device usage right to the power supplier S and does not want to control the device for some reason, for example, the device is controlled by a sudden visitor. In such a case, the right to use the device can be bought back from the power supplier S. However, the power supplier S suffers the risk of exceeding the contracted power due to a decrease in controllable equipment, so that it can be charged to the power consumer as a penalty, and repurchase at a price higher than the price at the time of purchase of the equipment usage right To be. By giving a penalty, the purchase of unnecessary equipment usage rights from power consumers is suppressed.

  When the power consumer buys back the device usage right, the control device 100 stores information on the device desired to be purchased from the terminal and information in the time unit by a predetermined time before the time unit set by the device usage right (for example, 2 hours before).
