Definitions
- the present invention relates to a system, method and computer program for managing (for example, prediction and / or adjustment) of consumption of energy such as electricity, gas and / or water.
- Patent Document 1 a demand side management technique is described. This technology requests consumers to reduce energy consumption when there is a time zone where load concentration is expected in the future, such as the next day, in the power supply system. And in response to the request, consumers who have switched their energy use at other times will be given incentives such as discounts on electricity charges in return. As a result, it is expected that the load concentration state of the power supply system is reduced or dispersed.
- demand-side management it is important to predict the magnitude of demand in advance in order to appropriately determine the amount of energy consumption reduction (in some cases, an increase amount).
- Demand forecasting is also important for properly formulating energy supply plans.
- Patent Document 2 in a server for demand side management, based on a control signal for instructing load adjustment to a load facility (for example, an air conditioner) of a consumer, operation result data of the load facility (for example, start time and Generates and stores stop time, operation time, load factor, presence / absence of load adjustment, load adjustment result (for example, the upper limit of load is limited to 70% of the rating), and the past load operation result data Based on this, it is disclosed to predict future demand and determine the load adjustment range.
- a load facility for example, an air conditioner
- operation result data of the load facility for example, start time and Generates and stores stop time, operation time, load factor, presence / absence of load adjustment, load adjustment result (for example, the upper limit of load is limited to 70% of the rating)
- load adjustment result for example, the upper limit of load is limited to 70% of the rating
- Demand side management has the problem of making demand prediction difficult while demand prediction is important in order to do it appropriately. This problem appears more prominently, for example, for a large number of consumers, rather than a personal or individual system for each consumer, such as HEMS (Home Energy Management System) that manages the energy of each household. In a public or collective energy management system, such as CEMS (Community Energy Management System) for managing the energy demand of the entire community.
- HEMS Home Energy Management System
- CEMS Common Energy Management System
- the consumer's past energy demand should be grasped.
- the method provided from the customer's smart meter to the CEMS is a record of the customer's energy consumption and does not necessarily represent the customer's true energy demand.
- the energy consumption performance of a consumer is the energy consumption as a result of intentional consumption adjustments, and in many cases is different from the actual energy demand of the consumer Will.
- CEMS should not force consumers to adjust consumption. Even if a request for consumption adjustment is issued from the CEMS to the community, not all consumers will adjust the consumption in response to the request. In addition, the consumer can freely determine how much adjustment is to be performed. Therefore, it is difficult for the CEMS to grasp which consumer has adjusted how much consumption in response to a request from the CEMS. It is difficult for the CEMS to specify the consumption adjustment amount and the actual demand amount from the energy consumption performance provided from the smart meter of the customer.
- one purpose is to more appropriately predict the future energy demand of the entire group of consumers such as a community.
- Another purpose is to more appropriately adjust the energy consumption of the entire group of consumers such as communities.
- a consumption adjustment request is generated. Some consumers are selected from the community as destination consumers for this consumption adjustment request. And the consumption adjustment request
- the energy demand of the community at the future specific period is predicted. This prediction is performed as follows. In other words, a non-selected consumer for a consumption adjustment request for a specific period in the past (for example, a past day with similar environmental conditions such as the next day and season or climate, or each time zone of the past day). The destination consumer is identified. The energy consumption performance of the identified non-destination customers in the past specific time is grasped. These grasped energy consumption performances can be estimated representing the actual energy demands of the identified non-destination consumers in the past specific period. Therefore, based on the energy consumption performance of those non-destination consumers, the demand of the community in the future specific time can be predicted.
- the first period when the energy consumption adjustment should be performed and the second period when the energy consumption adjustment should be suspended are determined. Based on the community's energy consumption performance in the past second period, The demand of the community in the first period is predicted. Based on the demand forecast, a request for adjustment of consumption in the first past period in the future is generated, and the request for adjustment of consumption is transmitted to consumers in the community.
- the future energy demand of a plurality of consumer groups such as a community can be predicted more appropriately.
- energy consumption of a plurality of consumer groups such as a community can be adjusted more appropriately.

- the present invention can also be applied to consumption management of energy other than power, such as gas and water.
- the term “consumption” of electric power is used not only in a general meaning of consumption (positive consumption) but also in a meaning including generation of electric power such as power generation (negative consumption). Therefore, for example, the “power consuming device” may include not only a device that only consumes power, such as an air conditioner, but also a device that generates power, such as a generator.

- FIG. 11 shows an operation flow of the adjustment request generation unit 133.
- the points to be noted in the operation are as follows.
- the adjustment request generation unit 133 selects not only all the consumers in the community but only some customers every day as the destination of the adjustment request. Since consumers who are not selected as destinations do not receive consumption adjustment requests, their consumption performance may be considered to represent the real demand of those consumers, and therefore the total demand It is used as basic data for total demand prediction by the prediction unit 125.
- the adjustment request generation unit 133 refers to the past request result data in the adjustment request database 115 every day, and grasps the number or frequency of each customer selected as a destination in the past, and the frequency or frequency. In response to this, it is determined which customer is selected as a destination for future requests. Thereby, the destination of the adjustment request can be distributed to different consumers, thereby reducing the problem that the requests are concentrated too much on the same consumer and the effect of the consumption adjustment request becomes saturated.
- the adjustment request generation unit 133 refers to the consumption performance database 103 every day according to the past consumption performance value of each consumer, in other words, according to the incentive value estimated from the consumption performance value. , Determine which consumer to select as a destination for future requests. Thereby, a request can be preferentially sent to a consumer with a relatively small incentive value. As a result, it is possible to reduce the problem that the effect of the consumption adjustment request becomes saturated by requesting again to the consumer who has already adjusted the consumption to the limit, while also suppressing the cost of incentives. The effect of the consumption adjustment request can be obtained.
- FIG. 2 shows an operation flow of the total demand result estimation unit 123.
- the total demand performance estimation unit 123 repeats the loop process S1 for each time zone for every time zone yesterday every day.
- the loop process S2 for each consumer is repeated for all the consumers in the community, and thereafter the processes of steps S7 to S8 are performed.
