Description

The present invention relates to a demand adjustment server and a demand adjustment system.

Conventionally, a method of allocating the adjustment amount of electric power demand has been known. For example, in a power demand adjustment system that adjusts power demand in an electric power system, the power demand adjustment power of the consumer equipment, the command amount of the adjustment control for the consumer equipment, and the power of the consumer equipment performed by the adjustment control. The adjustment amount of the power demand is distributed to each consumer device or to a predetermined group including a plurality of consumer devices based on the characteristic curve representing the correlation with the evaluation amount representing the command responsiveness determined based on the consumption amount. A method of doing so is known (Patent Document 1). In the prior art described in Patent Document 1, the adjustment amount of the electric power demand is distributed based on the responsiveness of the electric power consumption of the consumer equipment to the adjustment control request.

An impact index that indicates the magnitude of the impact of implementing the demand reduction amount using the demand reduction amount calculation means that calculates the power that can be reduced in the above as the demand reduction amount and the environmental information or demand reduction amount of each of the control categories. The impact index determining means for determining the above and the control category are combined based on the impact index, and each set of the control categories generates a plurality of demand reduction plans in which the total value of the demand reduction amount is gradually increased. Equipment control that controls the electrical equipment belonging to the control category according to the demand reduction plan generation means and the demand reduction amount of each control category included in the demand reduction plan selected by the external device among the plurality of demand reduction plans. A power supply / demand adjusting device including means is known (Patent Document 2). In the prior art described in Patent Document 2, the demand reduction amount is calculated in consideration of the number of people.

Further, conventionally, a method of determining an incentive according to the adjustment of electric power demand has been known. For example, a demand curve is obtained by obtaining a data acquisition unit that acquires the next-day operation plan of a storage battery in a state where no incentive is given for charging and discharging by the storage battery from a customer, and a demand curve in a state where no incentive is given based on the next-day operation plan. And the target demand curve creation unit that finds the target demand curve that equalizes the power demand represented by the demand curve at the predetermined time of the next day based on the next day operation plan, and the target demand curve created by the target demand curve creation unit. A power demand adjustment device including an incentive determination unit that determines the next day incentive for each time zone at a predetermined time based on the difference from the demand curve and an incentive notification unit that notifies the next day incentive determined by the incentive determination unit is known. (Patent Document 3). In the prior art described in Patent Document 3, the next day incentive for each time zone is determined based on the difference between the target demand curve and the predicted demand curve.

In addition, a signal transmission unit that broadcasts a DR signal, which is a signal requesting consumers to execute demand response, and a calculation unit that calculates a reward amount, which is a consideration for demand response, for each of a plurality of consumers, and a system. It is equipped with a database that records data of the amount of power supplied (index power amount), and the calculation unit is the amount of reduced power (adjusted power) that is the amount of system supply power reduced (or increased) by the consumer executing the demand response. There is known a demand response system that calculates the amount of compensation so that the larger the amount), the higher the amount of compensation (Patent Document 4). In the prior art described in Patent Document 4, the total amount of remuneration is distributed according to the magnitude of the adjusted electric energy to calculate the amount of remuneration for each consumer.

Further, the management device 16 transmits the result of the time change of the electric power demand in the demand request time zone to the server 20 by the communication unit (not shown).

Further, the management device 16 compares the time change of the electric power demand up to the present with the time change of the presented target electric power demand in real time, and presents the comparison result.

The server 20 predicts the time change of the electric power demand of the consumer group based on the actual time change of the electric power demand of each consumer and the setting of the degree of adjustment cooperation of each consumer, and the electric power of the consumer group. In addition to adjusting the time change of demand, the time change of the target power demand of the consumer obtained from the time change of the power demand of the adjusted consumer group is transmitted to each customer and presented.

As shown in FIG. 2, the server 20 includes a communication unit 22 and a calculation unit 24. The calculation unit 24 includes a consumer information database 30, a classification unit 32, a target demand calculation unit 34, and a reward calculation unit 36. The target demand calculation unit 34 is an example of the target demand presentation unit.

The communication unit 22 receives from the management device 16 a setting of the degree to which adjustment cooperation can be performed for each customer. In the setting, the degree of cooperation is "high", which indicates that the customer is actively able to adjust and cooperate, and the degree of cooperation is "medium", which indicates that the customer is passively adjustable. The degree of cooperation "low" indicating that is included. It should be noted that the management device 16 may transmit the setting to the extent that adjustment cooperation is possible on a daily basis.

Further, the communication unit 22 receives from the management device 16 the actual time change of the electric power demand of the consumer. The actual transmission from the management device 16 shall be carried out on a daily basis. Further, the communication unit 22 receives from the management device 16 a time change of the adjustment cooperation scheduled rate (reduction rate with respect to the normal usage amount) on the next day. The next day's adjustment cooperation schedule rate shall be transmitted on a daily basis.

The consumer information database 30 stores the time change of the electric power demand of each consumer and the time change of the target heat demand of each customer.

The consumer information database 30 stores the setting of the degree of adjustment cooperation possible for each customer, the actual time change of the electric power demand, and the change of the adjustment cooperation scheduled rate on the next day. For example, the next day's adjustment cooperation schedule rate table for each customer is stored (Table 1).

The classification unit 32 divides the consumer group into a plurality of classifications according to the degree of coordination cooperation. For example, consumers with a high degree of cooperation are classified into group A, consumers with a degree of cooperation of "medium" are classified into group B, and customers with a degree of cooperation of "low" are classified into group C. Classify.

The target demand calculation unit 34 calculates and presents the time change of the target electric power demand to each of the consumers. Specifically, as shown in FIG. 3, the target demand calculation unit 34 includes a cooperation schedule rate acquisition unit 40, a consumer demand forecast unit 42, a demand adjustment unit 44, a first demand presentation unit 46, and a second demand presentation unit. It includes 48 and a third demand presentation unit 50.

The cooperation schedule acquisition rate acquisition unit 40 acquires the time change of the adjustment cooperation schedule rate from the consumer information database 30 for each customer belonging to the A group having a degree of “high” adjustment cooperation possible.

The consumer demand forecasting unit 42 predicts the time change of the electric power demand of the customer on the next day based on the accumulated actual results of the time change of the electric power demand of the customer. Specifically, a daily demand forecast curve for each customer on the next day is created based on the accumulated data in the past.

Further, the consumer demand forecasting unit 42 predicts the time change of the electric power demand of the consumer group based on the time change of the electric power demand predicted for each consumer. Specifically, the daily demand forecast curve of each customer is combined to create the daily demand forecast curve of the entire customer group.

The demand adjustment unit 44 adjusts the time change of the predicted power demand of the consumer group so as to optimize the operation of the plant. Specifically, the daily demand forecast curve of the entire consumer group is scrutinized, and a plant manufacturing plan curve, which is a daily demand forecast curve adjusted so that the plant operation becomes rational and efficient, is created. For example, the projected power demand of the entire consumer group based on the operating efficiency of each device operating in the plant, the fluctuation of the operating efficiency of each device, the contracted energy amount of the plant, and the predetermined peak cut. The plant manufacturing plan curve is generated in consideration of the following points of view so as to reduce the time change.

-Energy saving by reducing the number of operating units. For example, reduce the time variation of power demand so as to shut down inefficient equipment.

-Improve economic efficiency by contract power by peak cutting and load leveling. For example, the time change of power demand is reduced according to the peak cut, or the time change of power demand is reduced so as to realize load leveling.

The first demand presentation unit 46 sets the time change of the power demand predicted for each customer belonging to the C group having a degree of “low” adjustment cooperation as the time change of the target power demand, and sets it as the time change of the target power demand. It is transmitted by 22 and presented by the management device 16 of the customer. As a result, the daily demand forecast of each customer in Group C is set as the demand, and each customer is notified. In addition, the time change of the remaining power demand is obtained by subtracting the time change of the power demand of each customer of the C group from the time change of the power demand of the adjusted consumer group.

The second demand presentation unit 48 for each customer belonging to Group A having a “high” degree of adjustment cooperation, predicts the time of power demand for the customer based on the time change of the adjustment cooperation schedule rate. The change is adjusted, and the adjusted time change of the power demand is transmitted by the communication unit 22 as the time change of the target power demand, and is presented by the management device 16 of the consumer. The time change of the remaining power demand is calculated by subtracting the time change of the power demand of each consumer of the Group A from the time change of the remaining power demand obtained by the first demand presenting unit 46.

The third demand presentation unit 50 synthesizes the time change of the electric power demand predicted for each customer belonging to the B group having a degree of "medium" adjustment cooperation, and is the second demand. If it is larger than the time change of the remaining power demand obtained by the presentation unit 48, the time change of the remaining power demand is proportionally apportioned according to the time change of the power demand predicted for the consumers belonging to the B group. Then, the time change of the electric power demand apportioned for the customer is transmitted by the communication unit 22 as the time change of the target electric power demand, and is presented by the management device 16 of the customer. Specifically, the time change of the power demand predicted for each consumer belonging to the B group is synthesized, and the time change of the remaining power demand obtained by the second demand presentation unit 48 is at least one time. When the value becomes large in, the time change of the remaining power demand is proportionally divided.

On the other hand, the third demand presentation unit 50 synthesizes the time change of the electric power demand predicted for each customer belonging to the B group having a degree of "medium" adjustment cooperation. 2 When it is equal to or less than the time change of the remaining power demand obtained by the demand presenting unit 48, the time change of the power demand predicted for the consumers belonging to the B group is set as the time change of the target power demand, and the communication unit 22 Is transmitted by, and is presented by the management device 16 of the customer. Specifically, the time change of the remaining power demand obtained by the second demand presentation unit 48 at all times is obtained by synthesizing the time change of the power demand predicted for each consumer belonging to the B group. When the value is less than or equal to the value of, the predicted time change of the power demand is used as it is as the time change of the target power demand.

If each customer in Group B does not agree on the time change of the presented power demand, the process returns to the processing of the demand adjustment unit 44, and the demand adjustment unit 44, the first demand presentation unit 46, and the second demand Each process of the presentation unit 48 and the third demand presentation unit 50 is repeated. At this time, the demand adjustment unit 44 reduces the adjustment amount. Further, when the customer management device 16 of the B group receives the time change of the electric power demand on the next day, it presents it, accepts the input of whether or not to agree, and transmits the accepted contents to the server 20.

The target demand calculation unit 34 stores the time change of the electric power demand in the demand request time zone calculated for each consumer in the consumer information database 30.

The remuneration calculation unit 36 is based on the time change of the target power demand presented to each customer for the customer, the actual time change of the power demand of the customer, and the classification result by the classification unit 32. Therefore, the higher the degree of coordination cooperation is, the higher the reward is, and the decrease in the daily cumulative demand of the actual time change of the power demand of the customer with respect to the daily cumulative demand of the time change of the target power demand. The reward is calculated so that the higher the degree, the higher the reward.

Specifically, as shown in FIG. 4, the reward calculation unit 36 includes a target demand acquisition unit 52, a demand record acquisition unit 54, a reward determination unit 56, and a reward granting unit 58.

After the demand request time zone, the target demand acquisition unit 52 acquires the time change of the electric power demand in the demand request time zone for each consumer from the consumer information database 30.

After the demand request time zone, the demand record acquisition unit 54 acquires the record of the time change of the electric power demand in the demand request time zone for each consumer from the consumer information database 30.

The remuneration determination unit 56 calculates the remuneration equivalent to the adjusted portion and the non-adjusted portion, and uses the total as the remuneration.

The reward equivalent to the adjustment amount means the reward for the adjustment of the demand request time zone, and the higher the degree of coordination cooperation is, the higher the reward for achieving the target, the target power demand for each time zone, and the actual power demand. The smaller the absolute value of the difference with, the higher the reward. The reward equivalent to the non-adjustment amount means the reward for energy saving by reducing the demand, and the larger the cumulative decrease rate of the actual daily power demand with respect to the cumulative daily target power demand, the more the reward. Make it high.

As described above, the reward to be given to each customer is calculated. This means that even if the demand request is not fully met, but a significant energy saving is realized, the reward can be obtained.

Specifically, the index for evaluating the adjustment of the demand request time zone is α (coefficient of cooperation form) × β (coefficient of request achievement), and the index for evaluating energy saving is γ (coefficient of reduction rate). , The reward is calculated from the sum of these indicators.

For example, the reward is calculated by the following STEP1 to STEP4.

(Α setting)
STEP1: The coefficient α of the cooperation form is set for each group. With Ai, Bj, and Ck as each customer
α (Ai) = a
α (Bj) = 0.5 × a
α (Ck) = 0
And.

(Β setting)
STEP2: The coefficient β of the degree of request achievement corresponds to the deviation between the target power demand LPt and the actual power demand actual Lt of each consumer in units of 1 hour each in the demand request time zone.
β (Ai, t) = b (when 0.00 ≦ | LPt-Lt | / LPt ≦ 0.03)
β (Ai, t) = 0.5 × b (when 0.03 << LPt-Lt | / LPt ≦ 0.05)
β (Ai, t) = 0 (in the case of 0.05 << LPt-Lt | / LPt)
Then, the sum total for the demand request time zone t is calculated and β is set as follows.
β (Ai) = Σβ (Ai, t)

Further, β (Bj) is also set in the same manner.

(Gamma setting)
STEP3: The reduction rate coefficient γ corresponds to the rate e that the consumer was able to save energy with respect to the cumulative target power demand during the demand request time zone.
γ (Ai) = c × e (Ai)
γ (Bj) = c × e (Bj)
γ (Ck) = c × e (Ck)
And.

(Calculation of reward)
STEP4: Reward R is calculated by the following formula.
R = α × β + γ

The reward giving unit 58 stores the reward R calculated for each customer in the customer information database 30.

As a change, it is transmitted by the communication unit 22 and presented by the management device 16 of the customer. In addition, the time change of the remaining power demand is obtained by subtracting the time change of the power demand of each customer of the C group from the time change of the power demand of the adjusted consumer group.

In step S108, the second demand presenting unit 48 forecasts each customer belonging to the A group having a degree of “high” adjustment cooperation possible, based on the time change of the adjustment cooperation scheduled rate. The time change of the electric power demand is adjusted, and the adjusted time change of the electric power demand is transmitted by the communication unit 22 as the time change of the target electric power demand, and is presented by the management device 16 of the consumer. The time change of the remaining power demand is calculated by subtracting the time change of the power demand of each consumer of the Group A from the time change of the remaining power demand obtained by the first demand presenting unit 46.

In step S110, the third demand presenting unit 50 synthesizes the time change of the electric power demand predicted for each customer belonging to the B group having a degree of "medium" adjustment cooperation. If it is larger than the time change of the remaining power demand obtained by the second demand presenting unit 48, the time change of the remaining power demand is changed to the time change of the power demand predicted for the consumers belonging to the B group. The time change of the electric power demand apportioned for the customer is transmitted by the communication unit 22 as the time change of the target electric power demand, and is presented by the management device 16 of the customer. Then, the demand adjustment processing routine is terminated.

Then, the management device 16 for each consumer measures the actual time change of the electric power demand from the operating status of the load device 10 and the power generation device 12 of the consumer, and obtains the actual time change of the electric power demand of the consumer. It is transmitted to the server 20 together with the identification number and the measurement date. Then, the server 20 stores the time change record of the electric power demand of each consumer in the consumer information database 30.
