Description

  The present invention relates to a power management apparatus, a management server, a local weather information generation system, and a local weather information generation method that generate useful information using an actual measurement value of a power generation amount of a power generation apparatus that generates power using natural energy. .

  It is known to make weather predictions based on cloud photographs from satellites and observation information observed by weather observation devices at various weather stations. With conventional weather forecasting, it is possible to forecast average weather over a wide area. On the other hand, detailed weather prediction, that is, local weather prediction is required. In order to localize the weather forecast, high-definition cloud photographs and / or local observation information are required. However, there is a limit to the refinement of cloud photos from satellites. Moreover, in order to localize observation information, many meteorological observation devices need to be scattered, but the number of installations is limited.

  By the way, in recent years, power generation devices using natural energy such as a solar power generation device and a wind power generation device have become widespread. Since the power generation amount of these power generators fluctuates according to weather information such as solar radiation (see Patent Document 1), there is a possibility that weather information can be acquired from the power generation amount. Therefore, there is a possibility that local weather information can be acquired from the power generation amount of the power generation devices scattered in various places.

Japanese Patent Laying-Open No. 2005-086953

  However, the amount of power generated by a power generation device using natural energy is affected by many parameters other than weather information. For example, in the case of a solar power generation device, the type of solar cell, rated capacity, number of series-parallel, installation orientation, inclination angle, panel temperature, wiring loss, conversion efficiency of the power conversion device, dirt on the panel surface, tendency to shadow Etc. are listed as parameters. These parameters are different for each photovoltaic power generator provided in each consumer.

  Therefore, in order to obtain a highly accurate solar radiation amount, it is necessary to accurately detect many parameters and obtain an optimal conversion formula in advance. However, since it is generally complicated to accurately detect these parameters, it has been difficult to obtain highly accurate solar radiation from a solar power generation device.

For example, ZigBee (registered trademark) is used for communication between the control unit 23 of the power management apparatus 12, the power conditioner 19, the first detection unit 21, the second detection unit 22, the output unit 24, and the storage unit 25. It is possible to employ communication using a short-range communication method such as.

  In FIG. 2, the load device 27 connected to the power management system is various electrical appliances such as a television, an air conditioner, and a refrigerator. The power conditioner 19 connected via the distribution board 20 supplies power to these load devices 27.

  The solar power generation device 16 generates power using sunlight. For this reason, the solar power generation device 16 includes a solar battery panel, and converts the energy of sunlight into DC power. In 1st Embodiment, the solar power generation device 16 assumes the aspect which installs a solar cell panel, for example on the roof of a house, and produces electric power using sunlight. However, in this invention, the solar power generation device 16 can employ | adopt arbitrary things, if the energy of sunlight can be converted into electric power.

  The power storage device 17 includes a storage battery, and can supply power by discharging the power charged in the storage battery. The power storage device 17 can also charge power supplied from the commercial power supply 26, the solar power generation device 16, the fuel cell device 18, or the like.

  The fuel cell device 18 includes a fuel cell, and generates direct-current power by a chemical reaction with oxygen in the air using hydrogen. Fuel cells include SOFC (Solid Oxide Fuel Cell), but other systems such as PEFC (Polymer Electrolyte Fuel Cell) and MCFC (Molten Carbonate Fuel Cell) generate power through chemical reaction between hydrogen and oxygen in the air. Do. The hydrogen used for power generation may be stored directly and supplied to the fuel cell, or stored as a hydrocarbon gas, hydrogen may be generated by reforming, and supplied to the fuel cell.

  The amount of power generation in the fuel cell device 18 varies depending on the amount of hydrogen and air supplied to the fuel cell. The fuel cell device 18 adjusts the power generation amount by adjusting the amount of hydrogen and air supplied to the fuel cell based on the control of the control unit 23.

  The power conditioner 19 converts DC power supplied from the solar power generation device 16, the power storage device 17, and the fuel cell device 18 into AC power. The power conditioner 19 also converts AC power supplied from the commercial power supply 26 into DC power for charging the power storage device 17.

  The power conditioner 19 can supply the distribution board 20 with the converted AC power and the AC power supplied from the commercial power supply 26. Further, the power conditioner 19 can supply the power storage device 17 with the DC power generated by the solar power generation device 16 and the fuel cell device 18 and the power supplied from the commercial power source 26 and converted into DC. Further, the power conditioner 19 can sell the converted AC power to the electric power company via the second detection unit 22. The power conditioner 19 supplies power based on the control of the control unit 23.

  The distribution board 20 distributes the supplied power to each load device 27.

  The first detection unit 21 is connected to the solar power generation device 16. The first detection unit 21 detects an instantaneous measured value of the amount of power generated by the solar power generation device 16 every 30 seconds, for example. The first detection unit 21 notifies the control unit 23 of the actually measured value of the detected power generation amount. The first detection unit 21 may be built in the power conditioner 19.

  The second detection unit 22 is a smart meter, for example, and is connected to the commercial power source 26 to detect the power supplied from the commercial power source 26. Moreover, the 2nd detection part 22 is connected also to the power conditioner 19, and detects the electric power which the solar power generation device 16 produces | generates and sells electric power to an electric power company. The second detection unit 22 may be built in the power conditioner 19. The second detection unit 22 notifies the control unit 23 of the detected power supplied from the commercial power supply 26 and the power sold to the power company.

  The power management apparatus 12 can be configured by, for example, an EMS (Energy Management System) represented by HEMS. The power management apparatus 12 includes an output unit 24, a storage unit 25, and a control unit 23.

  The output unit 24 is an I / F connected to the network 11 and can communicate various information including power generation information with the network 11. The output unit 24 is connected to the control unit 23 and acquires information to be communicated from the control unit 23. The output unit 24 can also acquire information via the network 11 and notify the control unit 23 of the information.

  The storage unit 25 is connected to the control unit 23 and accumulates various information collected by the control unit 23. The storage unit 25 can be configured by an arbitrary memory device or the like.

  The control unit 23 acquires information from the power conditioner 19, the first detection unit 21, the second detection unit 22, and the load device 27. The control unit 23 controls and manages the component devices in the power management system 15 based on the acquired information. Moreover, the control part 23 produces | generates information, such as power generation information, based on the acquired information.

  Specifically, for example, the control unit 23 controls the power consumption of these load devices 27 by being connected to the load devices 27 by wire or wirelessly.

  Further, the control unit 23 monitors the power supplied from the power conditioner 19 to the load device 27 through the distribution board 20 by being connected to the power conditioner 19 by wire or wirelessly.

  The control unit 23 also monitors the power charged in the power storage device 17 via the power conditioner 19.

  Further, as described above, the control unit 23 loads the electric power generated by the solar power generation device 16, the electric power discharged by the power storage device 17, the electric power generated by the fuel cell device 18, and the load device 27 of the electric power from the commercial power supply 26. Supply to the power storage device 17 of the power from the solar power generation device 16, the fuel cell device 18, and the commercial power source 26, and to the electric power company of the power generated by the solar power generation device 16 and the fuel cell device 18 Control the power sale.

  Furthermore, the control unit 23 generates power generation information together with the storage unit 25. The generation of power generation information by the control unit 23 will be described in detail below.

  As described above, the control unit 23 acquires an actual measurement value of the power generation amount at that moment from the first detection unit 21 every 30 seconds. Based on the power generation amount acquired from the first detection unit 21, the control unit 23 calculates an actual measurement value of the power generation amount at every specific time, for example, every 30 minutes between 0:00 and 23:30. To do. The actual measurement value of the power generation amount at a specific time is an average value of the power generation amount over a certain period of time based on the specific time. For example, the actual measurement value of the power generation amount at 0:00 is an average value of the power generation amount for 30 minutes from 23:45 to 0:15. When the control unit 23 calculates the actual measurement value of the power generation amount at a specific time, the control unit 23 stores it in the storage unit 25. The memory | storage part 25 can memorize | store the measured value of the electric power generation amount for several days, for example, 30 days.

  When the actual measurement value of the power generation amount is newly stored in the storage unit 25, the control unit 23 has the same time as the actual measurement value to be newly stored in the actual measurement values for 30 days stored in the storage unit 25. The maximum value of the actual measurement value is searched. For example, when the time of the actual measurement value of the power generation amount to be newly stored is 11:30, the control unit 23 searches for the maximum value among the actual measurement values of the power generation amount at 11:30 in the past 30 days. To do.

  The control unit 23 generates a maximum actually measured value that is the searched maximum value as power generation information together with the actually measured value newly acquired from the first detecting unit 21, that is, the latest actually measured value at a specific time. The control unit 23 notifies the management server 14 of the power generation information generated via the output unit 24 and the network 11. The control unit 23 notifies the management server 14 of position information where the power management system 15 is provided together with the power generation information, for example, position information such as latitude and longitude, or an address.

  Next, a detailed configuration of the management server 14 will be described with reference to FIG. FIG. 3 is a functional block diagram illustrating a schematic configuration of the management server 14. As illustrated in FIG. 3, the management server 14 according to the first embodiment includes an acquisition unit 28 and an information generation unit 29.

  The acquisition unit 28 acquires power generation information and position information from each power management apparatus 12 for each consumer via the network 11. The acquisition unit 28 acquires a wide area maximum value, which will be described later, from the provider server 13 via the network 11.

  Based on the power generation information, the position information, and the wide area maximum value, the information generation unit 29 generates the local solar radiation amount at the position where the power management system 15 is provided as the local weather information. The information generation unit 29 stores the generated local weather information in the database 31. Moreover, the information generation part 29 can create a local weather map based on the generated local weather information. Moreover, the information generation part 29 can create a local weather distribution map based on a local weather map. The information generating unit 29 can also display the created local weather map and local weather distribution map on the monitor 30. Furthermore, the information generation part 29 can estimate local weather based on the time change of a local weather distribution map.

  The wide area maximum value, local weather information, local weather map, local weather distribution map, and local weather estimation will be described in detail below.

  As described above, it is possible to calculate the amount of solar radiation in a wide area as wide-area weather information based on cloud photographs from satellites and observation information observed by meteorological observation devices at various weather stations. . When the business operator server 13 acquires the observation information, the business operator server 13 calculates wide-area weather information in the first region to the sixteenth region for each specific time. For example, as shown in FIG. 4, the first region to the sixteenth region are regions obtained by equally dividing a range surrounded by north latitude a to north latitude b and east longitude c to east longitude d.

  The company server 13 recognizes the maximum value from 30 days ago to the previous day for the wide area weather information for each specific time in each area as the wide area maximum value for each specific time in the area. For example, when 11:00 wide area weather information (amount of solar radiation) in the first region is recorded as shown in FIG. 5, the maximum amount of solar radiation 22 days before is recognized as the wide area maximum value. The management server 14 acquires the wide area maximum value from the business operator server 13 via the network 11. The first region to the sixteenth region where the wide area maximum value is provided are examples, and the region where the solar radiation amount and the wide area maximum value can be obtained is not limited to the first region to the sixteenth region.

  In order to calculate the local weather information, the information generation unit 29 determines the time of the latest measured value included in the acquired power generation information. Further, the information generation unit 29 determines which of the first area to the sixteenth area includes the area including the position corresponding to the acquired position information.

  The information generation unit 29 searches for the wide area maximum value of the determined area at the same time as the determined time. For example, when the power generation information with the latest measured time as 11:00 is acquired from the power management system 15 existing in the first area, the information generation unit 29 sets the wide area at 11:00 in the first area. Find the maximum value.

  The information generation unit 29 divides the product of the current actual measurement value B and the wide area maximum value D by the maximum actual measurement value A, that is, generates (B × D) / A to generate local weather information. That is, the local weather information is a value obtained by multiplying the relative frequency of the current power generation amount with respect to the assumed maximum power generation amount by the regional weather information such as the solar radiation amount. The management server 14 acquires power generation information and position information from the power management systems 15 scattered in various positions, and the information generation unit 29 generates local weather information for each power management apparatus 12.

  The information generation unit 29 stores a table of local weather information at a specific time of each generated power management apparatus in the database 31 (see Table 1).

  Table 1 is a table of local weather information at 11 o'clock, for example, and the information generation unit 29 stores the local weather information table in the database 31 for each specific time even for another specific time.

  The information generating unit 29 can create a local weather map using a table of local weather information. For example, as shown in FIG. 6, the local weather map is a diagram in which values of local weather information at a specific time are plotted on a map.

  Moreover, the information generation part 29 can produce a local weather distribution map as shown in FIG. 7 using a local weather map. The local weather map is a diagram in which regions having the same local weather information are separated by boundary lines.

  Furthermore, the information generation unit 29 can estimate changes in local weather based on local weather distribution maps at different times. For example, from the change in the region that is the same local weather information (insolation amount) from the local weather distribution map 30 minutes ago (see FIG. 8A) to the current local weather distribution map (see FIG. 8B), A local weather distribution map after 30 minutes (see FIG. 8C) is created.

  Next, the operation of the local weather information generation system according to the first embodiment shown in FIG. 1 will be described with reference to the sequence diagram of FIG.

  The power management apparatus 12 periodically calculates an actual measurement value of the power generation amount at a specific time (see reference sign “s1”). The power management apparatus 12 searches the storage unit 25 for the maximum actual measurement value at the same time as the calculated actual measurement time (see reference sign “s2”). The power management apparatus 12 notifies the management server 14 of the newly calculated actual measurement value and the searched maximum actual measurement value as power generation information (see reference sign “s3”). In addition, the power management apparatus 12 notifies the management server 14 of the position information.

  The company server 13 periodically calculates wide-area weather information for each of the first region to the sixteenth region (see symbol “s1”). The business entity server 13 recognizes the wide area maximum value for each of the first area to the 16th area based on the calculated wide area weather information (see reference sign “s2”). The business entity server 13 notifies the management server 14 of the wide area weather information (see symbol “s3”).

  The management server 14 generates local weather information for each power management apparatus 12 based on the acquired power generation information, position information, and wide area maximum value (see reference sign “s4”). The management server 14 stores the generated local weather information in the database 31 (see symbol “s5”).

  Thereafter, the local weather information at each time is accumulated in the database 31 by the same processing in the power management apparatus 12, the operator server 13, and the management server 14 (see reference numeral “s6”). When the management server 14 detects an input instructing creation of a local weather map, the management server 14 creates a local weather map based on the local weather information stored in the database 31 (see reference numeral “s7”).

  According to the power management apparatus of the first embodiment configured as described above, it is possible to create power generation information that allows local weather information to be calculated with higher accuracy than in the past. Such an effect will be described below.

  In each solar power generation device 16, since the ratio of the amount of solar radiation that generates the amount of power generation to the amount of power generation (hereinafter referred to as the first ratio) is constant, the power management is performed by multiplying this ratio by the actual value of power generation. It is possible to calculate the amount of solar radiation (local weather information) around the system 15. In order to obtain the first ratio, it is necessary to individually measure the amount of solar radiation around the power management system 15. However, as described above, in the current weather observation, it is difficult to measure the amount of solar radiation around each power management system 15, and it is difficult to obtain the first ratio.

  Therefore, the power management apparatus 12 according to the first embodiment acquires the amount of solar radiation around the power management system 15 by using the fact that the influence of clouds disappears during clear weather. That is, if there is no influence of clouds, the amount of solar radiation in a wide area and the amount of solar radiation in a local area are substantially equal, and the amount of solar radiation in a wide area during clear weather is converted into the amount of solar radiation around each power management system 15. It can be regarded approximately. Further, it is considered that the amount of solar radiation and the amount of power generation are maximized during clear weather, and that there are clear days in 30 days. Therefore, the maximum values of the amount of solar radiation and the amount of power generation in the past 30 days can be regarded as the amount of solar radiation and the amount of power generation during fine weather.

  Therefore, in the first embodiment, the maximum actual measurement value and the wide area maximum value are regarded as the specific power generation amount of each solar power generation device 16 and the amount of solar radiation that generates the specific power generation amount, so that the solar power generation device 16 is concerned. It is possible to calculate the first ratio with higher accuracy than in the prior art.

  Moreover, in 1st Embodiment, the influence of the fluctuation factor by the time of the solar radiation amount and the electric power generation amount of each solar power generation device 16 can be reduced. The installation locations of the respective solar power generation devices 16 are various, and depending on the installation location, shadows such as neighboring buildings and mountains may enter the solar cell panel at a specific time zone. The first ratio can vary depending on the time due to such a variation factor depending on the time such as a shadow. Therefore, in the first embodiment, the fluctuation of the first ratio according to the time is reduced by using the maximum actual measurement value and the wide area maximum value for each specific time.

  Moreover, in 1st Embodiment, the influence of the seasonal variation factor of the solar radiation amount and the electric power generation amount of each solar power generation device 16 can be reduced. For example, the panel temperature and the sun height are different between summer and winter. Due to such seasonal variation factors, the first ratio may vary depending on the season. Therefore, in the first embodiment, the fluctuation of the first ratio according to the season is reduced by using the maximum actually measured value and the wide area maximum value for a certain period on the basis of the current time.

  Next, a local weather information generation system including a management server according to the second embodiment of the present invention will be described. The second embodiment is different from the first embodiment in that the maximum actual measurement value is obtained in the management server. The second embodiment will be described below with a focus on differences from the first embodiment. In addition, the same code | symbol is attached | subjected to the site | part which has the same function and structure as 1st Embodiment.

  FIG. 10 is a block diagram illustrating a schematic configuration of a local weather information generation system including a management server according to the second embodiment. As illustrated in FIG. 10, the local weather information generation system 100 according to the second embodiment includes a network 11, a third detection unit 320, a provider server 13, and a management server 140. The configurations and functions of the network 11 and the operator server 13 are the same as those in the first embodiment.

  The third detection unit 320 is connected to the solar power generation device in the same manner as the first detection unit 21 in the first embodiment. For example, the power generation amount of the power generated by the solar power generation device every 30 seconds. Instantaneously measured values are detected. Further, the third detection unit 320 is connected to the network 11 and notifies the management server 140 of instantaneous measured values detected via the network 11. In addition, the third detection unit 320 notifies the management server 140 of position information where the photovoltaic power generation apparatus is provided, along with instantaneous measured values. In the second embodiment, the solar power generation device is installed in, for example, a streetlight 33 and a traffic light 34.
