Description

  The present invention relates to a power identification system, a power identification method, and a program for identifying power derived from renewable energy flowing into a power system.

  In recent years, with the increasing importance of protecting the global environment, expectations for renewable energy such as solar power generation have increased, and various renewable energy power generation systems have been actively introduced or planned.

  Currently, the power generated by renewable energy is used by flowing back into the power grid of general power companies, or by self-consumption within the installation location or storing it in a storage battery installed at that location. .

  By the way, in order to control the supply and demand balance of power and to receive and supply power between consumers, by storing the supplied power for each user, the technology for identifying the power by supply destination and the power supply In this case, a technique has been proposed in which power is identified for each supply source by adding the IP address or packet address of the power supply source to the power (see, for example, Patent Documents 1 to 3).

JP 2011-229268 A JP 2011-142771 A JP 2011-182641 A

  By the way, with the further spread of renewable energy in the future, the purchase amount and supply amount will change depending on the type of renewable energy used for power generation, or the power supply destination will specify the type of renewable energy used for power generation Thus, it is considered that the information on which renewable energy is used to generate power, such as purchasing power, is meaningful.

  However, there is no difference in the electric power generated with different renewable energy, and the techniques described in Patent Documents 1 to 3 can identify the electric power by supply destination or supply source. Electricity cannot be identified for the type of renewable energy.

  Therefore, unless the power of each generator of renewable energy is measured, the power could not be identified as a type of renewable energy, so there was a problem that it took cost and labor to install the measuring instrument . Currently, the power value measured by the measuring instrument determines the purchase price, but even if the power value is illegally increased by operating the measuring instrument, the power value measured by the measuring instrument is validated. There was also a problem that fraud could not be found because it could not be proved.

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

Therefore, the description of the present embodiment does not limit the contents of the invention described in the claims.

<First Embodiment>
<Configuration of power identification system>
FIG. 1 is a diagram showing a configuration of a power identification system 1 according to the first embodiment of the present invention. The power identification system 1 is a system for identifying power derived from renewable energy, and includes a power generation facility 100, a power collection device 200, an analysis server 300, and a power separation device 400. Here, renewable energy is energy renewed in natural phenomena such as sunlight, wind power, geothermal heat, tidal power, and the like. In the present embodiment, one power collection device 200 is provided for a power generation facility 1001 facility. In the figure, the solid line indicates the flow of environmental information, and the dotted line indicates the flow of power.

  The power generation facility 100 includes a generator that generates electric power from renewable energy, and is a facility that generates electric power derived from the renewable energy. As shown in the figure, the power generation facility 100 includes a renewable energy generator 110ab, an environmental sensor 120ab, and a measuring instrument 130. The power generation facility 100 may include a power generator that generates electric power other than that derived from renewable energy, for example, electric power derived from oil or coal.

  The renewable energy generator 110ab is a solar power generator, a wind power generator, a geothermal power generator, or the like. In FIG. 1, the power generation facility 100 includes two renewable energy generators 110ab, but the number of the renewable energy generators 110 may be one or three or more. When the power generation facility 100 includes a plurality of renewable energy generators 110, each generator may be a generator that uses the same renewable energy, or uses different types of renewable energy. It may be a generator. When the renewable energy generator 110ab is not distinguished, it is simply referred to as the renewable energy generator 110.

  The environmental sensor 120ab is provided around the renewable energy generator 110, and detects environmental information that affects the amount of power generated by the renewable energy generator. In the present invention, the environmental sensor 120a is provided around the renewable energy generator 110a, and the environmental sensor 120b is provided around the renewable energy generator 110b. When the environmental sensor 120ab is not distinguished, it is simply referred to as the environmental sensor 120. For example, when the renewable energy generator 110 is a solar power generator, the environment sensor is a solar radiation meter and acquires the amount of solar radiation as environmental information. The environmental sensor 120 may continuously detect the environmental information, or may detect the environmental information at a timing when the measuring instrument 130 measures the power value.

  In the present embodiment, the number of environmental sensors 120 is the same as that of the renewable energy generator 110. However, when the generator included in the power generation facility 100 is only the renewable energy generator 110, at least the renewable energy generator 110. The number may be one less than the number of types. For the power value of the renewable energy generator 110 that is not equipped with the environmental sensor 120, the power value of each renewable energy generator 110 that is equipped with the environmental sensor 120 is subtracted from the power value measured by the measuring instrument 130. It is because it can be obtained.

  If there is an environmental sensor in advance around the renewable energy generator, it is used. Thereby, the cost and labor in introducing this system can be reduced.

  The measuring instrument 130 measures the power value generated by the power generation facility 100, that is, the total power value generated by the renewable energy generator 110 provided in the power generation facility 100. The measuring instrument 130 may continuously measure the power value generated by the power generation facility 100, or may periodically measure the power value generated by the power generation facility 100.

  In the present invention, even if a measuring instrument is provided for each renewable energy generator 110 and each power value is not measured, it is possible to set the power value to the type of renewable energy by using the information of the environmental sensor described later. The power value for each renewable energy generator 110 can be obtained. The measuring instrument 130 may be installed on a distribution board provided in the power generation facility 100 in advance, or may be installed independently of the distribution board.

  The power collection device 200 collects information about the power from the power generation facility 100 and the power generated by the power generation facility 100, and acquires a power value acquisition unit 210, an environment information acquisition unit 220, a power information transmission unit 230, and a power transmission unit. 240. Note that the power collection device 200 may be provided independently, or may be provided in a distribution board installed in advance in the power generation facility 100.

  The power value acquisition unit 210 acquires a power value from the measuring instrument 130 of the power generation facility 100. In the present embodiment, the power value acquisition unit 210 acquires a power value in response to the power value being measured by the measuring instrument 130.

  The environmental information acquisition unit 220 acquires environmental information from the environmental sensor 120 of the power generation facility 100. At this time, the environment information acquisition unit 220 also acquires information for identifying the environment information acquired by the environment sensor. The information for identifying environmental information is information for uniquely identifying, for example, that the environmental information is the amount of solar radiation, wind speed, temperature, and the like. In the present embodiment, the environmental information acquisition unit 220 also acquires environmental information in response to the environmental information detected by the environmental sensor 120.

  The power information transmission unit 230 transmits the power value acquired by the power value acquisition unit 210 and the environment information acquired by the environment information acquisition unit 220 and information identifying the environment information to the analysis server 300 via the network. The timing to transmit to the analysis server 300 may be arbitrary.

  The power transmission unit 240 transmits the power acquired from the power generation facility 100 to the power system.

  The analysis server 300 is a server that identifies electric power generated by a power generation facility including a renewable energy generator according to the type of renewable energy, and includes an identification unit 310 and an electric energy estimation unit 320. Note that the power estimation unit 320 may not be provided in the analysis server 300 when the power amount of the renewable energy generator 110 is not estimated.

  Based on the environmental information acquired from the power collection device 200 and the power conversion efficiency of each renewable energy held in advance by the analysis server, the identification unit 310 converts the power value acquired from the power collection device 200 into renewable energy. And the identification result is obtained. The acquired identification result is transmitted to an external device such as the power separation device 400 that uses the identification result, or accumulated in a storage unit in the power collection device 200. The identification result acquired by the identification unit 310 is obtained as a combination of a renewable energy and a power value identified as being derived therefrom, such as a solar power value 20 W and a wind power value 10 W. Note that the power conversion efficiency combined with the environment information acquired from the power collection device 200 is selected based on information for identifying the environment information acquired from the power collection device 200.

  For example, when identifying the power of a power generation facility equipped with solar power generation and wind power generation, the environmental information acquired from the power collection device 200 and the power conversion efficiency of each renewable energy held in advance by the analysis server Based on the above, by calculating the following equation (1), it is possible to distinguish between the power value of solar power generation and the power value of wind power generation.

  Note that the power conversion efficiency is not the general power conversion efficiency of renewable energy, but the power conversion efficiency announced by the manufacturer of the renewable energy generator 110 provided in the power generation facility 100, or renewable energy power generation. The power conversion efficiency of the machine may be used. Thereby, the accuracy of the identification result can be increased.

  Next, FIG. 2 shows a verification result of whether or not the identification result acquired by the identification unit 310 is valid. In addition, each power value in this figure is a value measured by the measuring instrument. The figure (a) shows the power value generated by the power generation facility including the solar power generator and the wind power generator, the power value generated by the solar power generator, and the power value generated by the wind power generator. The figure graphed along time passage is shown. FIG. (B) shows a graph in which the power value of the solar power generator and the amount of solar radiation of the environmental information of the solar power generation are graphed over time. FIG. (C) shows a graph of the power value of the wind power generator and the wind speed of the environmental information of the wind power generation over time.

  Fig. (B) shows that there is a strong correlation between the power value of the solar power generator and the amount of solar radiation, and Fig. (C) shows a strong correlation between the power value of the wind power generator and the wind speed. I understand that there is. From this, it is possible to identify the power using environmental information such as the amount of solar radiation and the wind speed, and the identification result obtained by identifying the power using the environmental information in the identifying unit 310 is valid. be able to.

  Based on the environmental information acquired from the power collection device 200 and the power conversion efficiency of each renewable energy held in advance by the analysis server 300, the power amount estimation unit 320 is configured for a predetermined time of each renewable energy generator. Estimate the amount of power. When the environmental sensor detects the environmental information once per minute, the electric energy (Wh) for an arbitrary s minute can be estimated using the following equation (2). As shown in FIG. 2, since there is a correlation between the electric power derived from renewable energy power generation and the environmental information, the electric energy estimated by the electric energy estimating unit 320 is also appropriate as in the identification result. Can do.

  The amount of power estimated by the power amount estimation unit 320 is information that guarantees the measurement value of the measuring instrument 130, and can be used to improve the reliability of a power purchaser or the like. In addition, when each of the renewable energy generators 110 is provided with a measuring instrument, it also serves as information for guaranteeing a measured value of each measuring instrument.

  Based on the identification result received from the analysis server 300 via the network, the power separator 400 separates the power acquired from the power collector 200 via the power grid into renewable energy types. The identified power is stored in each storage battery, or supplied to the consumer via the power system together with the same type of power generated by other power generation facilities.

  Thereby, for each renewable energy, it can be determined whether to store electricity or supply it to the consumer. As a result, it is possible to change the price by looking at the demand and supply for each renewable energy, or to specify the renewable energy used to generate the power that the customer receives. become.

  FIG. 3 is a diagram showing a flowchart of the power identification process in the power identification system 1 according to the first embodiment of the present invention.

  First, in step S <b> 1, the power value acquisition unit 210 acquires the power value measured by the measuring instrument 130 of the power generation facility 100.

  Next, in step S <b> 2, the environment information acquisition unit 220 acquires environment information measured by the environment sensor 120 of the power generation facility 100. In addition, step S1 and step S2 may be simultaneous, and any may be first.

  Next, in step S3, the power information transmission unit 230 transmits the power value acquired in step S1 and the environment information acquired in step S2 to the analysis server 300.

  Next, in step S4, the identification unit 310 acquires from the power collection device 200 based on the environmental information acquired from the power collection device 200 and the power conversion efficiency of each renewable energy held in advance by the analysis server. The identified power value is identified as the type of renewable energy, and the identification result is acquired.

  As described above, according to the present embodiment, instead of a measuring instrument that requires electrical work, an environmental sensor that can be easily installed by anyone without work is used, or a measuring instrument is used if there is an environmental sensor. By reducing the power consumption by one, it is possible to appropriately identify the electric power derived from the renewable energy that has flowed into the electric power system efficiently without incurring cost and labor on the system. It is also possible to guarantee the validity of the amount of power flowing into the power system.
