  Here, the distributed energy indicates not the electric energy itself supplied from the electric power company (system power supply) but the electric energy and thermal energy generated in the demand area. Further, the distributed energy indicates electric energy or thermal energy having a plurality of uses, without the use of energy being fixed (limited).

  For example, distributed energy is supplied from a solar power panel or a wind power generator, electric energy stored in a storage battery using nighttime power supplied from a system power supply, or a gas company Electric energy generated by a household fuel cell using gas, electric energy generated by a micro gas engine using gas supplied from a gas company, heat energy generated by heat, and electricity business Heat energy generated by a heat pump type electric water heater or a conventional water heater using electric power supplied from a person (system power supply).

The management data analysis unit 12 includes a data organization unit 31, a health level determination unit (health level determination unit) 38, a priority level determination unit (priority level determination unit) 35, and a contribution level determination unit (contribution level determination unit) 37. Including.

  The data organizing unit 31 receives management data from the management data acquiring unit 11, averages the received management data, and outputs the averaged management data to the management data output unit 13. The data organizing unit 31 thins out the received management data and outputs it to the management data output unit 13. For example, the data organizing unit 31 receives the output energy value sent from the operation state information acquiring unit 21 for a predetermined period, averages the received output energy value, and outputs the averaged output energy value to the management data output unit 13. Further, the data organizing unit 31 receives the output energy value sent from the operation state information acquiring unit 21 at a predetermined interval, and outputs the received output energy value to the management data output unit 13.

  Further, the data organizing unit 31 reads the energy data, sensor data, and power data from the operation state information storage unit 41, the environmental parameter storage unit 42, and the power data storage unit 43, respectively, and reads the read energy data, sensor data, and power data. May be averaged or thinned out and output to the management data output unit 13.

  The health level determination unit 38 analyzes the management data acquired by the management data acquisition unit 11 based on a predetermined standard, and determines the health level of the operating state of each distributed energy supply device. Here, the health level is an index indicating the operating state of the distributed energy supply device 2, and includes at least one health level among the following first to fifth health levels. The health level determination unit 38 determines the health level of the operation state of each distributed energy supply device based on at least the operation state information acquired by the operation state information acquisition unit 21. The health level determination unit 38 includes a safety determination unit (safety determination unit) 32, a deterioration determination unit (first deterioration determination unit, second deterioration determination unit) 33, and an output rate calculation unit (output rate calculation unit) 34. And an efficiency calculation unit (efficiency calculation means) 36.

  The safety determination unit 32 acquires the operating state information of the distributed energy supply device 2 and determines whether the acquired operating state information is within a safety range indicating the range of the operating state information during normal operation. To do. Then, the safety determination unit 32 outputs the safety determination result to the management data output unit 13 as the first health level.

  Specifically, the safety determination unit 32 specifies one of the distributed energy supply devices 2 managed by the energy management apparatus 1 and outputs the output of the distributed energy supply device 2 specified from the operation state information acquisition unit 21. The energy value is received, the safe output value range stored in the reference data storage unit 44 is read, and it is determined whether or not the received output energy value is within the safe output value range. When the safety determination unit 32 determines that the output energy value is within the safe output value range, the management data output unit uses information indicating that the specified distributed energy supply device 2 is safe as the first health level. 13 is output. On the other hand, when the safety determination unit 32 determines that the output energy value is not within the safe output value range, the management data includes information indicating that the specified distributed energy supply device 2 is dangerous as the first health level. Output to the output unit 13.

  In addition, when the temperature sensor is attached to the specified distributed energy supply device 2, the safety determination unit 32 determines that the temperature of the specified distributed energy supply device 2 is that of the distributed energy supply device 2 during normal operation. It may be determined whether or not the temperature is within a safe temperature range indicating the temperature range.

  In addition, when the safety determination unit 32 determines safety based on a plurality of indexes among the output energy value, the input energy value, and the device parameter, when all the operating state information is determined to be within the safe range Only, the information indicating that the specified distributed energy supply device 2 is safe is output to the management data output unit 13. In other cases, the safety determination unit 32 outputs information indicating that the identified distributed energy supply device 2 is dangerous to the management data output unit 13.

  As described above, the management data output unit 13 displays the determination result of the safety determination unit 32 on the display unit 52 and notifies the user of the determination result of the safety, so that the user can determine which distributed energy supply device 2 is. It is possible to know whether it is in a dangerous state, stop the operation of the distributed energy supply device 2 in the dangerous state, and prevent the occurrence of breakage, rupture, ignition, or the like.

  Note that the safety determination unit 32 may determine the safety in three or more stages instead of the two-stage determination of safety or danger. In this case, a plurality of safety determination ranges are stored in the reference data storage unit 44 according to the degree of safety determination.

  The degradation determination unit 33 acquires the operating state information of the distributed energy supply device 2, compares the acquired operating state information with the past operating state information of the distributed energy supply device 2, and determines the distributed type It is determined whether or not the energy supply device 2 has deteriorated. The deterioration determination unit 33 outputs a third health degree indicating the degree of deterioration of the distributed energy supply device 2, which is a determination result of the presence or absence of deterioration, to the management data output unit 13.

  Specifically, the degradation determination unit 33 identifies one of the distributed energy supply devices 2 managed by the energy management apparatus 1 and outputs the output energy of the distributed energy supply device 2 identified from the operation state information acquisition unit 21. Receive value. Next, the deterioration determination unit 33 reads a plurality of past output energy values of the specified distributed energy supply device 2 from the operation state information storage unit 41, and calculates an average of the read past output energy values. Then, the deterioration determination unit 33 reads the first deterioration determination threshold value from the reference data storage unit 44, and the difference between the received output energy value and the calculated average value of past output energy values is the first deterioration determination value. It is determined whether or not it is larger than the threshold value.

  When the deterioration determination unit 33 determines that the difference between the received output energy value and the calculated average value of past output energy values is larger than the first deterioration determination threshold, the specified distributed energy supply device 2 is deteriorated. The information indicating that this is being performed is output to the management data output unit 13 as the third health level. On the other hand, when the deterioration determination unit 33 determines that the difference between the received output energy value and the calculated average value of past output energy values is equal to or less than the first deterioration determination threshold value, the specified distributed energy supply device 2 outputs information indicating normality to the management data output unit 13 as the third health degree.

  Further, the deterioration determination unit 33 acquires the operation state information of the distributed energy supply device 2 and the operation state information of the distributed energy supply device 2 of the same type as the distributed energy supply device 2, and acquires both of the acquired The operating state information is compared to determine whether or not the distributed energy supply device 2 has deteriorated. Then, the deterioration determination unit 33 outputs the fourth health level indicating the degree of deterioration of the distributed energy supply device 2, which is a determination result of the presence or absence of deterioration, to the management data output unit 13.

  Specifically, the degradation determination unit 33 identifies one of the distributed energy supply devices 2 managed by the energy management apparatus 1 and outputs the output energy of the distributed energy supply device 2 identified from the operation state information acquisition unit 21. Receive value. Furthermore, the output energy value of the distributed energy supply device 2 of the same type as the specified distributed energy supply device 2 is received. Next, the deterioration determination unit 33 reads the second deterioration determination threshold value from the reference data storage unit 44, and the output energy value of the specified distributed energy supply device 2 and the same type of dispersion as the specified distributed energy supply device 2 It is determined whether or not the difference from the output energy value of the type energy supply device 2 is greater than a second deterioration determination threshold value.

  When the deterioration determination unit 33 determines that the difference is larger than the second deterioration determination threshold, the management data output unit uses information indicating that the specified distributed energy supply device 2 is deteriorated as the fourth health degree. 13 is output. On the other hand, when the deterioration determination unit 33 determines that the difference is equal to or smaller than the second deterioration determination threshold value, the management data includes information indicating that the specified distributed energy supply device 2 is normal as the fourth health degree. Output to the output unit 13.

  Here, the same type of distributed energy supply device 2 means a distributed energy supply device 2 having the same principle of power generation, power storage, and heat generation by the distributed energy supply device 2. For example, if two distributed energy supply devices 2 are both solar cell panels, they are the same type of distributed energy supply device 2. Moreover, even if it is not the same model, the storage battery for electric vehicles and the stationary battery for home use may be regarded as the same type of distributed energy supply device 2.

  In this way, the management data output unit 13 displays the determination result (third health level or fourth health level) of the deterioration determination unit 33 on the display unit 52, and notifies the user of the determination result of the presence or absence of deterioration. Thus, the user can know which distributed energy supply device 2 has deteriorated, and can recognize which distributed energy supply device needs to be maintained or replaced.

  Note that the deterioration determination unit 33 may determine the degree of deterioration in three or more stages, instead of determining whether the deterioration is normal or deterioration. In this case, a plurality of first and second deterioration determination threshold values are stored in the reference data storage unit 44 according to the degree of deterioration.

  The output rate calculation unit 34 acquires the output energy value of the distributed energy supply device 2, compares the acquired output energy value with the ideal output energy value, and determines the ideal of the distributed energy supply device 2. The second health level, which is an output rate indicating the ratio of the current state to the correct state, is calculated.

  Specifically, the output rate calculation unit 34 specifies one of the distributed energy supply devices 2 managed by the energy management apparatus 1 and outputs the output of the distributed energy supply device 2 specified from the operation state information acquisition unit 21. The energy value is received, the ideal output energy value stored in the reference data storage unit 44 is read, and an output rate that is a ratio of the received output energy value to the read ideal output energy value is calculated. The output rate calculation unit 34 outputs the calculated output rate to the management data output unit 13.

  Note that the output rate calculation unit 34 may calculate the ideal output energy value instead of reading the ideal output energy value from the reference data storage unit 44. In this case, for example, the input energy value of the specified distributed energy supply device 2 is acquired from the input energy measuring device 3, the ideal conversion efficiency is read out from the reference data storage unit 44, and is read out into the acquired input energy value. The ideal output energy value is calculated by multiplying the conversion efficiency.

  The efficiency calculation unit 36 acquires the input energy value and the output energy value of the distributed energy supply device 2, compares the acquired input energy value with the output energy value, and the ratio of the output energy value to the input energy value The fifth health degree which is the efficiency indicating the above is calculated.

  Specifically, the efficiency calculation unit 36 identifies one of the distributed energy supply devices 2 managed by the energy management device 1 and inputs the input energy of the distributed energy supply device 2 identified from the operation state information acquisition unit 21. The value and the output energy value are received, and an efficiency that is a ratio of the received output energy value to the received input energy value is calculated. The efficiency calculation unit 36 outputs the calculated efficiency value to the management data output unit 13 as the fifth health level.

  The priority order determination unit 35 acquires the health level (first to fifth health levels) of each distributed energy supply device 2 determined by the health level determination unit 38, and acquires each of the distributed energy supply devices 2 acquired. Based on the health level, the priority of at least one of the necessity for operation control of each distributed energy supply device, the necessity for maintenance, and the necessity for replacement is determined. The priority order determination unit 35 outputs the determined priority order to the management data output unit 13.

  Specifically, for example, the priority order determination unit 35 acquires the health level (first to fifth health levels) of each distributed energy supply device 2 from the health level determination unit 38. Next, the priority order determination unit 35 reads the conversion table from the reference data storage unit 44, converts the acquired health degree into a numerical value and converts it into a health value for each distributed energy supply device 2. And the priority determination part 35 multiplies all the converted health values, and calculates the total health value of each distributed energy supply apparatus 2. FIG. The priority order determination unit 35 determines the priority order in order from the lowest total health value calculated for each distributed energy supply device 2, and outputs the determined priority order to the management data output unit 13.

  Here, the distributed energy supply device 2 having a low total health value is considered to have a poor operating state because the output energy value or the like is reduced due to a failure or aged deterioration. If the distributed energy supply device 2 having a low total health value is left as it is, damage, rupture, ignition, etc. may occur. Therefore, the distributed energy supply device 2 having a lower total health value needs to be preferentially subjected to operation control such as operation stop and operation suppression, maintenance such as repair and replacement of parts, and replacement of the device itself. Therefore, the management data output unit 13 displays the priority order determined by the priority order determination unit 35 on the display unit 52 and notifies the user of the priority order, so that the user can determine which operating state of the distributed energy supply device 2. It can be determined whether it is better to preferentially control, or which distributed energy supply device 2 should be preferentially maintained or replaced.

  Note that the priority order determination unit 35 preferentially performs maintenance or replacement for which device based on the acquired health level, the years of use of the device, the lifetime of the device, the maintenance cost or replacement cost of the device. The order indicating whether or not the effect is high may be determined.

  The contribution determination unit 37 acquires the efficiency of each distributed energy supply device 2 calculated by the efficiency calculation unit 36, reads the contribution determination table from the reference data storage unit 44, and refers to the read contribution determination table. Thus, the degree of contribution corresponding to the acquired fifth health level is determined for each distributed energy supply device 2. Then, the contribution determination unit 37 outputs the determined contribution of each distributed energy supply device 2 to the management data output unit 13.

  Further, the contribution determination unit 37 acquires the efficiency of each distributed energy supply device 2 calculated by the efficiency calculation unit 36, and the efficiency of a certain distributed energy supply device 2 and the certain distributed energy supply device. 2 is compared with the efficiency (average value) of the distributed energy supply device 2 of the same type, and the degree of contribution of the certain distributed energy supply device 2 is determined. Specifically, the contribution determination unit 37 sets the contribution to “high” if the efficiency of a certain distributed energy supply device 2 is greater than the efficiency (average value) of the same type of distributed energy supply device 2. If the efficiency of a certain distributed energy supply device 2 is equal to or less than the efficiency (average value) of the same type of distributed energy supply device 2, the degree of contribution is determined as “low”.

The contribution determination unit 37 acquires the efficiency calculated by the efficiency calculation unit 36, and indicates the contribution degree of the device to the environment based on the acquired efficiency, the environmental cost (CO ₂ ) of the device, and the subsidy system. The degree may be determined.

  Further, the management data analysis unit 12 may calculate the power generation contribution degree to the power consumption of each distributed energy device based on the output energy value, the purchased power, and the power consumption.

  Further, the management data analysis unit 12 may perform analysis with higher accuracy with reference to environmental parameters, purchased power, and power consumption.

  The storage unit 40 includes a control program and an OS program executed by the control unit 10, and various functions (for example, a safety determination process, a deterioration determination process, and an output rate calculation process described later) that the control unit 10 has in the energy management device 1. , A priority determination process, an efficiency calculation process, a contribution determination process, and the like) are stored. In the present embodiment, the storage unit 40 includes, for example, an operation state information storage unit (storage unit) 41, an environmental parameter storage unit 42, a power data storage unit 43, and a reference data storage unit 44. Remember. The storage unit 40 is realized by, for example, an EPROM (Erasable Programmable ROM), an EEPROM (Electrically EPROM), a flash memory, or the like, which is a nonvolatile memory capable of rewriting contents. As described above, the storage unit that stores information that does not require rewriting of contents may be realized by a ROM that is a read-only semiconductor memory, not shown, different from the storage unit 40.

  The operation state information storage unit 41 stores operation state information in which an input energy value, an output energy value, or a device parameter value is associated with a time. The operation state information stored in the operation state information storage unit 41 may be, for example, data illustrated in FIG. 3A shows the input energy value of the device A which is the distributed energy supply device 2, FIG. 3B shows the output energy value of the device A which is the distributed energy supply device 2, and FIG. (C) shows the temperature (device parameter) of the device A which is the distributed energy supply device 2 measured by the temperature sensor which is the device external sensor 5a.

  The environmental parameter storage unit 42 stores environmental parameters in which environmental parameter values are associated with times. The environmental parameter stored in the environmental parameter storage unit 42 may be, for example, data illustrated in FIG. FIG. 4A shows the solar radiation intensity measured by the solar radiation intensity sensor which is the external environment sensor 5b, and FIG. 4B shows the outside of the distributed energy supply device 2 measured by the temperature sensor which is the external environmental sensor 5b. Indicates the ambient temperature.

  The power data storage unit 43 stores power data in which a power amount and time are associated with each other. The power data stored in the power data storage unit 43 may be, for example, data illustrated in FIG. Fig.5 (a) shows the electric power purchased from the electric power company (electric power supplied from an electric power company to a consumer), and FIG.5 (b) is energy consumption, such as a household appliance installed in the demand place The power consumption of the apparatus 7 is shown.

  As shown in FIGS. 3 to 5, the operation state information storage unit 41, the environmental parameter storage unit 42, and the power data storage unit 43 include an input energy value, an output energy value, and a device parameter of each distributed energy supply device 2. By storing the environmental parameters, the purchased power and the power consumption, the management data analysis unit 12 can analyze the management data acquired using the past management data, and further, the management data analysis unit 12 Can also analyze past management data.

  The reference data storage unit 44 stores reference data used when the management data analysis unit 12 analyzes management data. Specifically, the reference data storage unit 44 includes a safety range used by the safety determination unit 32, first and second deterioration determination threshold values used by the deterioration determination unit 33, and an ideal output used by the output rate calculation unit 34. The energy value, the conversion table used by the priority determination unit 35, and the contribution determination table used by the contribution determination unit 37 are stored. The reference data stored in the reference data storage unit 44 may be, for example, data illustrated in FIG. 6A shows a safe output value range and a safe temperature range for each distributed energy supply device, and FIG. 6B shows a first deterioration determination threshold value for each distributed energy supply device. (C) shows the 2nd degradation determination threshold value for every distributed energy supply apparatus, FIG.6 (d) shows the ideal output energy value for every distributed energy supply apparatus, FIG.6 (e) shows health. FIG. 6F shows a contribution determination table in which efficiency and contribution, which are the fifth health degree, are associated with each other.

  The safety range indicates the range of the operating state information of the distributed energy supply device 2 during normal operation. Therefore, if the operating state information of the distributed energy supply device 2 is within the safe range, it can be determined that the distributed energy supply device 2 is operating normally, while the operation of the distributed energy supply device 2 is performed. If the state information is not within the safe range, it can be determined that the distributed energy supply device 2 is not operating normally and is in an abnormal state. The safe range includes a safe output value range indicating a range of output energy values included in the operation state information, a safe temperature range indicating a temperature range which is a device parameter included in the operation state information, and the like.

  The safe output value range indicates a range of output energy values of the distributed energy supply device 2 during normal operation. Therefore, if the output energy value of the distributed energy supply device 2 is within the safe output value range, it can be determined that the distributed energy supply device 2 is operating normally, while the distributed energy supply device 2 If the output energy value is not within the safe output value range, it can be determined that the distributed energy supply device 2 is not operating normally and is in an abnormal state.

  The safe temperature range indicates the temperature range of the distributed energy supply device 2 during normal operation. Therefore, if the temperature of the distributed energy supply device 2 is within the safe temperature range, it can be determined that the distributed energy supply device 2 is operating normally, while the temperature of the distributed energy supply device 2 is If it is not within the safe temperature range, it can be determined that the distributed energy supply device 2 is not operating normally and is in an abnormal state.

  As described above, whether the safety determination unit 32 is within the safety range for at least one of the input energy value, the output energy value, and the device parameter included in the operation state information of the distributed energy supply device 2. By determining whether or not, it is possible to determine whether the operation of the distributed energy supply device 2 is safe or dangerous. Of course, the operation state of the distributed energy supply device 2 can be more accurately determined by using a plurality of data included in the operation state information.

  The first deterioration determination threshold is a half value of the maximum value of the fluctuation range of the operating state information of the distributed energy supply device 2 that has not deteriorated. In other words, the deterioration determination threshold is a value corresponding to a half value of the fluctuation range of the operating state information that can be taken by the distributed energy supply device 2 that has not deteriorated. That is, if the difference between the average value of the operating state information of the distributed energy supply device 2 in the past state of no deterioration and the current operating state information of the distributed energy supply device 2 is greater than the first deterioration determination threshold value. It can be determined that the distributed energy supply device 2 has deteriorated.

  The second deterioration determination threshold value is a half value of the maximum value of the fluctuation range of the operation state information of the same type of distributed energy supply device 2 under the same condition. In other words, the second degradation determination threshold value is a value corresponding to a half value of the fluctuation range of the operating state information that the same type of distributed energy supply device 2 may be able to take under certain conditions. That is, if the difference between the operational state information of a certain distributed energy supply device 2 and the operational state information of another distributed energy supply device 2 of the same type is greater than the second degradation determination threshold, the certain distributed energy supply It can be determined that the device 2 has deteriorated.

  Here, the first deterioration determination threshold value shown in FIG. 6B and the second deterioration determination threshold value shown in FIG. 6C are only threshold values relating to the output energy value, but the safety shown in FIG. Like the range, the first deterioration determination threshold value and the second deterioration determination threshold value may include threshold values related to device parameters and input energy values.

  The ideal output energy value is a standard (theoretical) output energy value for a certain input energy value. Accordingly, by comparing the output energy value of the distributed energy supply device 2 with the ideal output energy value, it is determined how much the output is performed with respect to the maximum value of the output capacity according to the standard of the distributed energy supply device 2. can do.

  The conversion table is for quantifying the first to fifth health degrees. As shown in FIG. 6E, if the first health level is “safe”, the first health value is 1, and if the first health level is “dangerous”, the first health value is Becomes 0.5. Further, the second health value is the same value as the output rate value which is the second health level. Note that the conversion table shown in FIG. 6E is an example, and it is desirable to set the conversion value based on the years of use of the equipment, the life of the equipment, the maintenance cost / replacement cost of the equipment, and the like.

The contribution determination table is for determining the contribution, and indicates the contribution corresponding to the efficiency value for each distributed energy supply device 2. In the example shown in FIG. 6F, the degree of contribution is shown in five stages, but the present invention is not limited to this. The degree of contribution may be two or more levels, and the efficiency range (threshold value) may be set according to the level. Note that the contribution determination table shown in FIG. 6F is an example, and it is desirable to set the contribution based on the environmental cost (CO ₂ ) of the device, the subsidy system, and the like.

[About processing executed by the management data analysis unit]
Next, the flow of processing executed by each unit of the management data analysis unit 12 will be described with reference to FIGS.

[Safety judgment processing]
First, the flow of the safety determination process executed by the safety determination unit 32 will be described with reference to FIG. FIG. 7 is a flowchart illustrating an example of the safety determination process.

  The safety determination unit 32 identifies one distributed energy supply device 2 that has not been determined for safety among the plurality of distributed energy supply devices 2 managed by the energy management device 1 (S1). Next, the safety determination unit 32 acquires the specified output energy value of the distributed energy supply device 2 from the operation state information acquisition unit 21 (S2). And the safety determination part 32 reads the safe output value range stored in the reference data storage part 44, and determines whether the acquired output energy value is in the safe output value range (S3).

  The safety determination unit 32 determines whether or not the output energy value of the specified distributed energy supply device 2 is within the safe output value range, and then determines all the distributed energy supply devices 2 managed by the energy management device 1. On the other hand, it is confirmed whether or not safety has been determined (S4). If there is a distributed energy supply device 2 that has not performed safety determination (NO in S4), the safety determination unit 32 repeats the processes of S1 to S3. The safety determination unit 32 determines the safety of all the distributed energy supply devices 2 managed by the energy management apparatus 1 (YES in S4), and then determines the safety of each distributed energy supply device 2. The determination result is output to the management data output unit 13 (S5).

  Here, the 1st health degree which safety judgment part 32 outputs to management data output part 13 may be data as shown in Drawing 8, for example. The data shown in FIG. 8 indicates that device A and device C are in a safe state, and device B and device D are in a dangerous state.

[Deterioration judgment processing]
Next, the flow of the deterioration determination process executed by the deterioration determination unit 33 will be described with reference to FIG. FIG. 9 is a flowchart illustrating an example of the deterioration determination process.

  The deterioration determination unit 33 identifies one distributed energy supply device 2 that has not been determined for deterioration from among a plurality of distributed energy supply devices 2 managed by the energy management apparatus 1 (S11). Next, the deterioration determination unit 33 acquires the specified output energy value of the distributed energy supply device 2 from the operation state information acquisition unit 21 (S12). Then, the deterioration determination unit 33 reads a plurality of past output energy values of the specified distributed energy supply device 2 from the operation state information storage unit 41, and calculates an average of the read past output energy values (S13). After calculating the average value, the deterioration determination unit 33 reads the first deterioration determination threshold value from the reference data storage unit 44, and the difference between the acquired output energy value and the calculated average value of past output energy values is: It is determined whether or not it is larger than the first deterioration determination threshold value (S14).

  After determining whether the difference between the specified output energy value of the distributed energy supply device 2 and the calculated average value of past output energy values is larger than the first deterioration determination threshold value, the deterioration determination unit 33 Then, it is confirmed whether or not the deterioration of all the distributed energy supply devices 2 managed by the energy management device 1 has been determined (S15). If there is a distributed energy supply device 2 that does not determine whether or not there is deterioration (NO in S15), the deterioration determining unit 33 repeats the processes of S11 to S14. The deterioration determining unit 33 determines whether or not there is deterioration for all the distributed energy supply devices 2 managed by the energy management apparatus 1 (YES in S15), and then determines whether or not each of the distributed energy supply devices 2 is deteriorated. Is output to the management data output unit 13 (S16).

  Here, the third health level output from the deterioration determination unit 33 to the management data output unit 13 may be data as illustrated in FIG. 10, for example. The data shown in FIG. 10 indicates that the devices A and C are in a normal state without deterioration, and the devices B and D are deteriorated.

  Moreover, the flow of another deterioration determination process which the deterioration determination part 33 performs is demonstrated based on FIG. FIG. 11 is a flowchart illustrating another example of the deterioration determination process.

  The deterioration determination unit 33 identifies one distributed energy supply device 2 that has not been determined for deterioration from among a plurality of distributed energy supply devices 2 managed by the energy management device 1 (S21). Next, the deterioration determination unit 33 determines whether or not the distributed energy supply device 2 of the same type as the specified distributed energy supply device 2 exists in the plurality of distributed energy supply devices 2 managed by the energy management device 1. Is confirmed (S22).

  Here, if there is no distributed energy supply device 2 of the same type as the specified distributed energy supply device 2 among the plurality of distributed energy supply devices 2 managed by the energy management device 1 (NO in S22), deterioration determination is performed. The unit 33 makes the determination result of the presence / absence of deterioration of the specified distributed energy supply device 2 impossible (S23). And the deterioration determination part 33 confirms whether the determination of the presence or absence of deterioration was performed with respect to all the distributed energy supply apparatuses 2 which the energy management apparatus 1 manages (S27).

  On the other hand, if there is a distributed energy supply device 2 of the same type as the specified distributed energy supply device 2 among the plurality of distributed energy supply devices 2 managed by the energy management apparatus 1 (YES in S22), the deterioration determination unit 33 acquires the output energy value of the specified distributed energy supply device 2 from the operation state information acquisition unit 21 (S24). Further, the deterioration determination unit 33 acquires the output energy value of another distributed energy supply device 2 of the same type as the identified distributed energy supply device 2 from the operation state information acquisition unit 21 (S25). Then, the deterioration determination unit 33 reads the second deterioration determination threshold value from the reference data storage unit 44, and outputs the output energy value of the specified distributed energy supply device 2 and another of the same type as the specified distributed energy supply device 2. It is determined whether or not the difference from the output energy value of the distributed energy supply device 2 is greater than the second degradation determination threshold value (S26).

  The deterioration determination unit 33 determines whether the difference between the specified output energy value of the distributed energy supply device 2 and the output energy value of another distributed energy supply device 2 of the same type is greater than the second deterioration determination threshold value. Then, it is confirmed whether or not the determination of the presence / absence of deterioration has been made for all the distributed energy supply devices 2 managed by the energy management apparatus 1 (S27). If there is a distributed energy supply device 2 that has not performed the determination of the presence or absence of deterioration (NO in S27), the deterioration determination unit 33 repeats the processes of S21 to S26.
