2 is a timing chart for explaining a demand response management method of a smart home according to an embodiment.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram showing a structure of a demand response management system of a smart home according to an embodiment.

As shown in FIG. 1, the demand response management system of the smart home according to the embodiment includes a demand response management system (DRMS) 10 and a gateway 30 installed in each home do.

Here, as a home having an intelligent life-oriented environment that enables convenience and welfare enhancement and safe living by converging information technology (IT) into a "smart home" residential environment, for example, smart This means that the energy efficiency can be optimized by exchanging real-time information in both directions, such as the grid, between the power supplier and the consumer.

Each of the homes transmits power consumption information and reduction capacity information of the smart home to the DRMS 10 through the gateway 30 in order to participate in a demand response service provided by the DRMS 10 to be described later.

The reduction capacity information includes, for example, a total demand reduction amount, a demand reduction available capacity, and a demand reduction substantial capacity calculated by installing and using a home energy monitoring system (HEMS).

The total demand reduction amount is a sum of the demand reduction capacity of the smart home demand reduction resource.

And the demand reduction available capacity is the sum of the demand reduction capacity of the smart home demand reduction available resource. Here, the demand reduction available resource is a resource that can actually be used as a demand reduction resource among the demand reduction resources.

In addition, the demand-reduction actual usable capacity is a sum of demand reduction capacities that can cause demand reduction in response to a demand response (DR) signal of the DRMS 10, which will be described later, among the demand reduction available resources. It can be affected by past performance.

Here, among the calculated information, the demand reduction actual usable capacity? The demand reduction usable capacity? The demand reduction total capacity may have the magnitude relation.

In addition, the power consumption information of each home can be collected from AMI (Advanced Metering Infrastructure).

The AMI is an infrastructure for providing bi-directional real-time power information by enabling bidirectional communication between a power provider and the customer, and is a smart meter 140, a data collecting unit (DCU) 150, An AMI-based remote meter reading information collection system (ADCS) 160, and a meter data management system (MDMS) 170.

The smart meter 140 is a device that develops a watt-hour meter, which is a device for periodically checking the amount of power used for charging, and is a device that can remotely check the amount of power used. The DCU 150 collects electric power demand data of each home in the smart meter 140 and provides electricity use information. The DCU 150 measures a price of electric power according to current electric power demand, (140). The ADCS 160 is a device that automatically collects power usage information of the DCU 150. The MDMS 170 is a device that stores and manages a large amount of power usage information collected from the DCU 150 for a long period of time. At this time, the DRMS 10 may be connected to the MDMS 170, for example.

The gateway 30 connects the communication network of the DRMS 10 and the communication network of the smart home. In addition, the gateway 30 periodically requests the DRMS 10 to inquire the demand reduction participation to confirm whether the DRMS 10 instructs the smart home to participate in the demand response service.

Here, the gateway 30 periodically requests the DRMS 10 for the demand reduction participating query until the response contents of the demand response service participation instruction are received from the DRMS 10. At this time, the gateway 30 may change the query request period according to the request period value in the response of the DRMS 10, for example, query the DRMS 10 at the query request period of the first 10 seconds to 10 minutes request.

Hereinafter, the DRMS 10 will be described in detail.

The DRMS 10 provides and manages a demand response service to each home for power demand reduction. At this time, the DRMS 10 generates demand response information based on the power consumption information of the smart home, transmits a DR signal based on the generated demand response information to the smart home through the gateway 30, Provide demand response service.

The demand response information includes a target demand reduction amount, an actual demand reduction amount, a reduction participation rate, an actual reduction participation rate, and the like.

The target demand reduction amount is a value allocated when the DR signal is generated in the DRMS 10, and is a sum of a target demand reduction amount included in the DR signal for demand reduction. And the actual demand reduction amount is the sum of actual demand reduction amounts actually achieved in response to the demand reduction amount of the DR signal.

Also, the reduction participation rate is calculated by the following equation (1) as a reduction participation participation ratio based on the reduction target based on the smart home demand reduction resources. At this time, the size of the demand reduction practical usable capacity of Equation (1) can be increased by the DRMS 10 sending the DR signal to the customer.

In addition, the actual reduction participation rate is calculated by the following formula (2) as the actual reduction participation participation rate of the smart home demand reduction available resources.

Also, the DRMS 10 may provide an incentive to each home that is a consumer as one of the demand response services. Here, the incentive may provide the actual demand reduction amount or the actual reduction participation rate of the available reduction resources.

For example, the incentive may be provided in units of points (points) / percentage (percentage) for the actual reduction participation rate of the available reduction resources. At this time, the incentive may be provided in proportion to a case where the actual reduction participation rate of the available reduction resources is equal to or greater than a reference value of 80%, for example. Also, when the actual reduction participation rate of the available reduction resources exceeds 100%, the incentive may be provided in the same manner as in the case where the demand reduction available capacity or the demand reduction actual usable capacity is miscalculated.

In addition, the DRMS 10 designs a control order for the gateway 30 of each home to manage the DR signal of the entire home appliance included in the smart home. At this time, management of DR signals for each home appliance included in the smart home is managed in the smart home of the corresponding home.

The control order design of the DRMS 10 is for preferentially selecting an active home for reducing the demand response in allocating a demand reduction amount to the gateway 30 of each home, The priority of the home gateway 30 is determined by the ranking assignment effect factor when securing the capacity for the target demand reduction capacity based on the demand reduction capacity of the home registered in the home server 30 and the past performance do.

The rank allocation influencing factors include the registered demand reduction capacity, the past performance, and the reliability of the contract. The registered demand reduction capacity is calculated by the following equation (3).

A1 = initial value 50 and can be adjusted by empirical statistic value.

Further, the past performance is calculated by the following equation (4).

B1 = initial value 100 and can be adjusted by empirical statistic value.

The reliability of the contract is calculated by the following equation (5).

C 1 is the initial value of 1 and can be adjusted by empirical statistical values.) (C 1 is the default value of the contract.

Here, the priorities of the gateways 30 of the respective homes are designed according to the rank order of the rank of the right side by customer = A x a + B x b + C x c. B = "past performance" weight (where 0 ≤ b ≤ 1.00), c = "contracted reliability" weight (where a = "registered demand reduction capacity" , 0? C? 1.00). And 0? A + b + c? 1.

One of the methods for achieving the demand reduction amount to be achieved by the DRMS 10 is to send a demand reduction instruction command to the gateway 30 of each home at a time interval, There is a way to go over the order.

For example, when the above-mentioned demand reduction instruction command is executed over a total of two (first and second) orders, when instructing the second demand reduction after the first demand reduction instruction, The time required for ensuring time is taken into account and the demand reduction amount to be allocated to each of the first order and the second order is allocated as shown in Equations (6) and (7) below, Is obtained from the secondary demand reduction instruction, and is allocated to the allocation coefficient to be secured for each order.

(Where 0.5 ≤ primary allocation coefficient ≤ 1.5)

Equation (6) indicates that the demand reduction target amount of the primary demand reduction instruction is at least 50% to less than 150% of the target total demand reduction amount.

(Where 1.0 ≤ primary allocation coefficient ≤ 1.5)

Equation (7) indicates that the demand reduction target amount of the secondary demand reduction instruction is equal to or more than 100% and less than 150% of the demand reduction amount not secured from the first demand reduction instruction at the target total demand reduction amount.

At this time, the incentives of the primary and secondary demand reduction directives may be applied differently to a plurality of market types. For example, there may be a market type that is applied as "primary demand reduction incentive unit price ≤ secondary demand reduction incentive unit price". Accordingly, each of the homes can determine one market type among the plurality of market types.

In addition, the maximum allowable time for registering the demand reduction capacity before execution of the demand reduction of each home (home) is, for example, 12 hours before the execution date in the primary demand reduction instruction and 6 hours before the execution date in the secondary demand reduction instruction Or 2 hours before the execution time in the primary demand reduction instruction and 1 hour before the execution time in the secondary demand reduction instruction. In addition, when the maximum allowable time is exceeded, the demand reduction capacity is not registered and is invalidated.

Hereinafter, a demand response management method of a smart home according to an embodiment will be described in detail.

2 is a timing chart for explaining a demand response management method of a smart home according to an embodiment.

As shown in FIG. 2, the DRMS 10 registers request information of the demand response service participation request of the smart home.

In order to register the demand reaction service participation request information, each smart home calculates a demand reduction capacity (24 sections per day) and a maximum demand reduction capacity by time zone using, for example, HEMS, The market type to participate in the response service is determined (500).

In order to participate in the demand reaction service, each smart home requests pre-registration to the DRMS 10 through the gateway 30 (501). Here, each smart home may request pre-registration according to the market type, but it can register only one market type.

Then, the DRMS 10 judges the legitimacy of the contents of the pre-registration request of the smart home, stores the contents of the request in the case of no abnormality, and stores the contents of the response of the normal registration in the smart home And transmits the error content including the contents of the error to the smart home device 30 requesting the pre-registration when the contents of the pre-registration request, the DRMS 10 itself, Through the gateway 30 (503).

Then, the smart home registered in the DRMS 10 transmits a request response service participation request request signal to the DRMS 10.

In order for the smart home to request a request to participate in the demand response service, the gateway 30 of each home should ask the DRMS 10 to participate in the demand reduction service in order to confirm whether or not the DRMS 10 instructs participation in the demand response service. (505).

Then, the DRMS 10 transmits a demand response service participation instruction signal to the registered smart home.

In order to direct the DRMS 10 to participate in the demanded response service in the registered smart home, the DRMS 10 responds to the demand reduction participation query request (506, 507).

Here, the DRMS 10 determines whether demand reduction is necessary for the inquiry request. If the demand reduction is not necessary, the DRMS 10 transmits a response content indicating that there is no demand response service participation instruction to the gateway 30 (506 (507), the response contents of the request for participating in the demand response service including the time required to reduce the demand to the gateway (30), the demand reduction request for each time slot, and the incentive are transmitted.

Then, the power consumption information and the reduction capacity information of the smart home for participating in the demand reaction service of the smart home receiving the demand reaction service participation instruction signal are registered in the DRMS 10.

The smart home receiving the demand response service participation instruction from the DRMS 10 through the gateway 30 to register the power consumption information and the reduction capacity information of the smart home in the DRMS 10 is transmitted to the DRMS 10 through the gateway 30 (509) to register with the DRMS 10 the demand reduction capacity by time zone that can substantially reduce the demand.

In this case, the actual demand reduction capacity by time slot is a capacity for demand reduction according to the time zone that can be accommodated by reflecting the present situation of the home within the demand reduction request capacity by time in the demand response service participation instruction information .

The DRMS 10 calculates and stores the demand reduction capacity of each home considering the demand reduction capacity transmitted from each home in the maximum value and stores the response content of the normal registration in the registration Transmits the requested error to the smart home through the gateway 30, and transmits the error content to the smart home through the gateway 30 (511).

In addition, each smart home can register the initial value of the maximum demand reduction capacity by time slot in the DRMS 10, and when the demand reduction capacity is changed by, for example, a facility change or an operation rule change, It can register in the DRMS 10. The demand reduction capacity of each smart home by the time slot is processed as a demand reduction capacity by time slot that is lastly transmitted at the time of the pre-registration request or is processed as a demand reduction capacity by time slot at the time of the demand reduction capacity registration request, Registered.

Then, the DRMS 10 generates demand response information based on the power consumption information and the reduction capacity information of the smart home registered in the DRMS 10, and provides the demand response service to the smart home.

In order to provide the demand response service to the smart home, the DRMS 10 performs settlement (600). In other words, the daily settlement of the DRMS 10 is performed, for example, once a day to check whether there is an order to participate in the demand reaction service for the previous day, and then evaluate the demand reduction performance of each smart home for each demand response service participation instruction .

Then, the DRMS 10 performs monthly settlement (603). That is, the monthly settlement of the DRMS 10 generates settlement information on a monthly basis, for example, about once a month, on the basis of the evaluation results of demand reduction performance of each smart home.

In addition, the DRMS 10 provides a method for the home to confirm its settlement information, and the settlement inquiry and settlement confirmation is performed for each home (605).

As described above, the demand response management system and management method of the smart home according to the embodiment generates and transmits the demand response information based on the power consumption information and the reduction capacity information of the smart home to provide the demand response service to the smart home And a gateway connecting the communication network of the DRMS and the DRMS and the communication network of the smart home by providing a demand response service to a plurality of homes in which a smart home is established, The reliability and efficiency of power supply and demand can be increased.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various changes, modifications and substitutions are possible within the scope of the technical idea of the present invention.
