During the distribution setting period, the energy consumption of the energy distribution object is set to reach the energy target amount.

In the information collection step, setting information set by the user (information about energy distribution target, distribution set period, and energy target ratio), measurement information by various sensors (information on control conditions), distribution set period and control conditions Energy distribution-related information such as calculation information (information on the effective range of the past correspondence period and control conditions) is collected.

The energy distribution object is an object managed by energy distribution, and consists of each device (3 levels) or each system (including the 2nd level - 3rd level) consisting of a combination of interconnected devices, or a combination of various systems It is classified by building (including level 1, 2, and 3), and is selected and set by the user.

[Table 1] is separated by device, system, and building for an example of an energy distribution target according to the present invention, and devices and systems are not necessarily limited thereto.

[Table 1]

The distribution setting period is a period set for energy distribution to an energy object, and is selected in various ranges by the user, such as yearly, monthly, daily, weekly, day of the week, quarterly, seasonal, specific period, etc. and is set

The target energy ratio is for calculating the target energy usage that the user wants to achieve during the distribution setting period, and is set by the user as a percentage (%).

The control condition is set by measuring the real-time outdoor air temperature (°C) and outdoor air humidity (%) at the time when energy management is performed by a sensor.

The effective range of the control condition is a range setting for extracting data similar to the control condition from the main DB, and the effective range of the control condition may be set to ±α°C outside air temperature and ±β% outside air humidity.

At this time, α is set within the range of 0.1 to 3, β is set within the range of 0.1 to 5, preferably, α is set within the range of 0.5 to 1.0, and β is set within the range of 2 to 3.

The past correspondence period is a period for extracting a usage pattern D corresponding to the distribution setting period from the main DB, and may be automatically set by a program according to the distribution setting period in consideration of the season and environmental change.

For example, in a region having four seasons such as Korea, if the distribution setting period is set from July 01, 2020 to August 31, 2020, the past correspondence period is from July 01, 2019 to 2019 It may be set for the period up to August 31, or it may be set for the period from July 01 to August 31 of a previous year with similar environmental conditions.

In addition, the past correspondence period may be manually set by the user. For example, if the distribution setting period is set from August 01, 2020 to August 31, 2020, the past correspondence period is set to the period from July 01, 2019 to September 30, 2019, or The corresponding period may be set as a period from July 01, 2020 to August 31, 2020 at the discretion of the user.

The main DBD stores all kinds of information related to building maintenance and energy management, such as building-related information, system-related information, device-related information, operation-related information, and the like.

The energy standard usage is for setting the target energy usage according to the energy target ratio, the total energy usage of the energy distribution target for the past corresponding period is extracted from the main DB, and the extracted total energy usage is set as the energy standard usage. . That is, the reference energy consumption means the total energy consumption for the energy distribution target during the past corresponding period regardless of the effective range of the control condition.

In addition, the information collection step includes a control means collection step in which information on the control means of the energy distribution target is collected by the control unit from the storage unit.

In the control means collection step, when the energy distribution target is set for each building (level 1), information on the operation period and operation status for each system installed in the entire building is collected, and various devices in the system for each system in which the operation is performed After information on the operation method and control method of the device is collected, information on the control means for each device is included in the information related to the energy distribution target and collected together.

At this time, the information on the driving method and the control method is collected information on the system in which the operation is performed at the time of analysis among various systems in the building. That is, information on the operating period for each system is collected by the data accumulated in the main DBD, and systems with different operating periods and different analysis points are excluded from energy management.

In addition, in the control means collection step, when the energy distribution target is set for each system (level 2), after information on the operation method and control method for various devices in the system is collected, information on the control means for each device is included in the energy distribution target-related information and collected together.

In addition, in the control means collecting step, when the energy distribution object is set for each device (3 levels), information on the control means for each device is included in the energy distribution object related information and collected together.

The operation method is information on whether the energy distribution target is an essential operation or intermittent operation target, and the control method is information on whether the energy distribution target is an on/off control method or a proportional control method target, and the control means is energy distribution It is information on the means for controlling the object, that is, the control means of the individual device being operated.

That is, when the device is essential operation and on/off control, there are no control means and control values, and when the device is essential operation and proportional control, the proportional control value corresponds to the control means, In the case of off-control, the start-stop value corresponds to the control means, and when the device is intermittent operation and proportional control, the proportional control value corresponds to the control means.

For example, the control means may correspond to a 'cooling water set temperature' in the case of a refrigerator, a 'cooling water set temperature' in the case of a cooling tower, an 'inverter frequency ratio' in the case of a cold water circulation pump, and a 'cooling set temperature' in the case of an EHP. .

In addition, when there is no control means for the device, the control means is collected as 'None (X)', and when the control means is collected as 'None (X)', it is excluded from the control target during the control value determination step. .

In addition, in the present invention, when there is no main DB in the information collection stage, the execution of the building energy management method using energy distribution is stopped, and the operation is performed according to the operation control set separately by the user, and related data according to the operation That is, various information related to building maintenance and energy management, such as building-related information, system-related information, device-related information, operation-related information, etc., are stored in real time to generate the main DBD.

The operation control set separately by the user means operation according to data of another building or operation according to the skill of the user, and since such operation control is in accordance with known technology, a detailed description thereof will be omitted.

The extraction step is a step in which the energy distribution target, the past correspondence period, and the usage pattern DB satisfying the control condition effective range are extracted from the main DB, and the control condition effective range is satisfied for the past corresponding period collected by the information collection step. The control value, energy usage, outside air temperature (℃), and outside air humidity (%) for the control means of the energy distribution target to be used are extracted from the main DB as a usage pattern DB by the calculation unit.

The control value is a numerical value of the control means, and in the case of a refrigerator, the set temperature of cold water (℃), in the case of a cooling tower, the set temperature of cooling water (℃), and in the case of a cold water circulation pump, it means a numerical value for the inverter frequency ratio (%) .

At this time, when there is no control value for the energy distribution target in the use pattern DB, the control value is extracted as ON or OFF. For example, when the operation method of device A is essential operation and the control method is on/off control, since there is no control means and control value, the control value of device A is ON or OFF in the usage pattern DB. will be extracted with

The energy consumption means an energy consumption amount of an energy distribution target according to a control value in the past correspondence period.

In addition, in the extraction step, when the usage pattern DB is not extracted from the main DBD, that is, when there is no usage pattern DB that satisfies the control condition effective range in the main DBD for the past corresponding period, the effective range of the control condition is automatically Alternatively, the extraction step may be performed by being readjusted by the user.

In addition, in the present invention, when the usage pattern DB is not extracted from the main DB during the extraction step, the operation according to the building energy management method using energy distribution is stopped, and the operation is made by the operation control set separately by the user, Through real-time storage of related data according to driving, the main DBD may be automatically generated.

The operation control set separately by the user means operation according to data of another building or operation according to the skill of the user, and since such operation control is in accordance with known technology, a detailed description thereof will be omitted.

The step of setting the target distribution amount is performed in the calculation unit according to the energy distribution related information and the usage pattern DB,
The setting of the distribution target amount may include a deriving step of deriving an average energy use amount and an energy use ratio (%) with respect to the energy use of the energy distribution target within the use pattern D;

a target energy consumption calculation step in which the target energy usage is calculated according to the energy standard usage and the target energy ratio;

a usage collection step in which the energy usage of the energy distribution target is measured and accumulated to collect the accumulated energy usage;

a distribution amount determining step in which an energy distribution amount is determined based on a difference between the target energy use amount and the accumulated energy use amount;

and a target amount setting step in which an energy distribution target amount to reach the target energy usage amount is set based on the energy distribution amount, according to the average energy use amount and the energy use ratio (%) derived in the derivation step.

In the derivation step, the average energy use amount and the energy use ratio (%) with respect to the energy use of the energy distribution target in the use pattern DB are derived. The average energy use amount and energy use ratio (%) are used as factors for setting the energy distribution ratio and the energy distribution target amount during the target amount setting step.

The target usage calculation step is a step in which the user's desired energy usage, ie, the target energy usage, to be used in the building management method during the distribution setting period is calculated. It is calculated according to the target energy ratio (%).

[Energy target amount = standard energy consumption × target energy ratio]

That is, when the standard energy consumption is 100 (㎾ｈ) and the target energy ratio is 90 (%), the target energy consumption is automatically calculated as 90 (㎾ｈ).

In the usage collection step, the energy usage of the energy distribution target according to the operation is automatically measured and calculated, and the accumulated energy usage from the start of the energy distribution setting period to the time when the usage collection step is performed (operation time) is collected.

In this case, the energy consumption of the energy distribution target is collected at various cycles such as fractionation, hourly, daily, day of the week, weekly, monthly, and the like, so that the accumulated energy consumption can be calculated.

The determination of the distribution amount is a step in which an energy distribution amount that can be distributed to an energy distribution target is determined in order to reach a target energy distribution amount, and the energy distribution amount corresponds to a remainder excluding the accumulated energy consumption from the target energy use amount.

[Energy distribution = target energy distribution - accumulated energy consumption]

That is, if the target energy consumption is 90(㎾ｈ) and the accumulated energy consumption is collected as 20(㎾ｈ) in the usage collection stage, the energy distribution is 90(㎾ｈ)-20(㎾ｈ) = 70(㎾) becomes a).

In the target amount setting step, the energy distribution ratio (%) to the energy distribution amount is determined, and the energy distribution target amount for the energy distribution target is set according to the energy distribution ratio (%).

As for the energy distribution ratio (%), the primary distribution ratio (%) is determined by the energy use ratio (%) in the derivation step, and the primary distribution ratio (%) This adjusted secondary distribution ratio (%) is determined, and the secondary distribution ratio (%) is determined as the energy distribution ratio (%).

The primary distribution ratio (%) is determined according to the energy use ratio (%) for the entire energy distribution target.

Primary distribution ratio (%) = [(target energy distribution / standard energy consumption) / (remaining period of energy distribution / set period of energy distribution)] × ratio of energy use by device

The secondary distribution ratio (%) is based on the energy distribution-related information, and the energy distribution target is divided into a control target device and a control target excluded device by the determination unit, and the energy use ratio (%) of the control target excluded device remains the same It is determined by the secondary distribution ratio (%), With respect to the equipment to be controlled, the primary distribution ratio (%) is adjusted by reflecting the secondary distribution ratio (%) of the equipment excluded from the control, and is determined by the secondary distribution ratio (%).

Secondary distribution ratio (%) = {1st distribution ratio - [(Energy use ratio of devices excluded from control - Primary distribution ratio of devices excluded from control) / Number of devices other than devices excluded from control]}

In this case, the device excluded from the control target corresponds to a device in which the control means is collected as 'None (X)' in the control means collection step.

The energy distribution target amount is determined by the average energy use amount and the energy distribution ratio (%) for all energy distribution targets in the usage pattern DB.

[Energy distribution target amount = energy distribution ratio (%) × average energy consumption]

The control value setting step is a step in which a control value for controlling the energy distribution target is calculated so that the operation according to the energy distribution target amount is performed, and the control value is determined by [Equation 1] below.

[Formula 1]

Energy consumption = (A × outside temperature) + (B × humidity) + (C × control value) + D

In this case, the constants A, B, C, and D are determined by the energy usage, control conditions, and control values based on the usage pattern DB.

In addition, the [Equation 1] is determined by the correlation analysis of energy usage, control conditions, and control values, and this correlation analysis is a well-known known statistical analysis (functionalization method) such as regression analysis. Since it is not only a description, but it is automatically performed by a program, a detailed description thereof will be omitted.

That is, in the control value setting step, the energy distribution target amount is set as the energy consumption for [Equation 1] in which the constants A, B, C, and D are determined based on the usage pattern DB, and the outside air temperature and outside air humidity are controlled By setting the conditions (outside temperature and humidity), the energy distribution target amount and the control value for each device satisfying the control condition are calculated and determined.

In the operation step, the operation of the energy distribution target is performed according to the control value determined in the control value setting step.

The repeated performing step is a step in which the control value is repeatedly re-determined so that the energy usage of the energy distribution target reaches the target usage during the distribution setting period, and the information collection step, the extraction step, the distribution target amount setting step, the control value determination step The operation step is repeated.

The repeating step may be set to be continuously performed in real time, or set to be performed in a long-running manner in accordance with a set period such as division, hour, day, day, week, month, season, year, and the like.

That is, according to the present invention, the control value for the energy distribution target is efficiently adjusted according to the set cycle of the repeating step.
