Description

  The present invention relates to an information processing system using renewable energy.

  There is a strong demand for the spread and utilization of renewable energy such as solar power generation and wind power generation in order to cope with the natural environment protection and the exhaustion of fossil energy.

  However, the amount of power generated by renewable energy fluctuates, and it is difficult to predict such fluctuation beforehand. Therefore, in order to level the amount of power generation, measures such as peak cut of power generation at a low level or leveling of supplied power by charging and discharging with a storage battery are taken.

  Such a renewable energy utilization environment has the following problems.

  First, the cost per unit of generation of renewable energy will be higher compared to existing nuclear, thermal and hydroelectric power generation schemes. For example, it is necessary to newly install a power grid for transmitting generated renewable energy, and the generation of waste due to the inability to use all of the generated energy power also causes a cost increase.

  Furthermore, when additional equipment such as a storage battery is provided to level power, the cost per unit of power generation is further increased.

  As a prior art regarding renewable energy utilization, there exist invention as described in patent documents 1-3, for example.

  The invention described in Patent Document 1 divides a power system into a plurality of independent power systems in order to enable the introduction of a large amount of renewable energy, and allows a system to be stably operated in cooperation with each other. It is presented.

  The invention described in Patent Document 2 is a system in which the user grasps the power supply rates of a plurality of power supply sources, selects a power purchase destination, and allows the user to use the image forming apparatus comfortably.

  Furthermore, the invention described in Patent Document 3 is a technology for realizing more efficient energy management in the entire factory, and it is possible to equalize the load of the factory according to prediction and achieve peak cut or more efficient energy management. It shows that adjustment including peak shift is performed.

  The techniques described in the prior art require additional facilities and controls, such as large scale batteries, power grids, etc., to obtain efficient power supply from distributed renewable energy sources.

  In such a case, as described above, there is a problem that the cost per generation unit of renewable energy is high.

  Therefore, in view of such a point, an object of the present invention is to perform additional processing of information processing such as execution of a program by using electric power generated by renewable energy, and to perform additional equipment such as a large-scale storage battery. Make it unnecessary. Another object of the present invention is to solve the problem that the cost per unit of power generation of the renewable energy is high by using a communication network instead of the power network.

  An embodiment of the present invention will be described below with reference to the drawings. The description of the examples is for understanding of the present invention, the scope of protection of the present invention is not limited to these examples, and the scope of protection is described in the claims. And those that approximate it.

  FIG. 1 is a view for explaining the outline of a first embodiment of an information processing system using renewable energy according to the present invention.

  In contrast to the information processing system 1 using the renewable energy of the present invention (hereinafter simply referred to as the information processing system 1), the user 100 is assumed to be a user of PaaS (Platform as a Service: information processing service infrastructure) Can. Therefore, the user 100 can execute information processing, that is, program execution using a simple framework for the information processing system 1.

  The information processing system 1 executes a software framework for distributed processing by the processing nodes P1 to PN which execute information processing using a plurality of renewable energy. The software framework in the information processing system 1 is invisible to the user 100.

  In FIG. 1, in order to use computer resources, the user 100 transmits information for processing information (a program, data, parameters indicating the size of the program and a file size) to the information processing system 1 via the network NW. . Then, the result processed by the information processing system 1 can be received.

  On the other hand, in the information processing system 1, the receiving node 10 receives the information for the information processing sent from the user 100.

  The information processing system 1 includes, as components, a plurality of information processing nodes P1 to PN distributed in a wide area through the network NW, and power supply sources PS1 to PSN with renewable energy to the information processing nodes P1 to PN.

  Here, as the distributed connection, for example, it may be distributed across a wide area separated from each other including Tokyo and Okinawa, or overseas.

  Furthermore, as a feature of the present invention, these components function intermittently without assuming constant operation. To this end, the power supply sources PS1 to PSN can include not only commercial power sources but also energy sources by small power generation such as solar power generation as renewable energy and wind power generation.

  FIG. 2 is a view for explaining the outline of a second embodiment of the information processing system using renewable energy according to the present invention.

  The configuration shown in FIG. 2 has a plurality of receiving nodes 101 to 10 n as a feature.

  The user 100 can select one favorite reception node among the plurality of reception nodes 101 to 10 n. The selection criteria at this time are the operating state of the receiving node and the communication status with a plurality of receiving nodes, and one receiving node is selected in consideration of such a situation.

  When one selected reception node is determined, information for information processing is sent from the user 100 to the reception node selected. The subsequent processing is the same as that described in FIG.

  FIG. 3 is a diagram for explaining the outline of still another third embodiment. In this embodiment, the functions of the plurality of receiving nodes 101 to 10 n are integrally provided with the corresponding processing nodes P1 to PN.

  Also in this configuration, the user 100 can select one favorite reception node among the plurality of reception nodes 101 to 10 n. When one reception node is selected, the subsequent processing is the same as that described in FIG.

  FIG. 4 is a flow chart showing an example of the distributed information processing executed by the information processing system 1 of the present invention.

  FIG. 5 is a block diagram of a configuration example of the information processing nodes P1 to PN.

  Each of the information processing nodes P1 to PN (denoted as a processing node P) has a processing device 11 and a power switching control unit 12. The processing device 11 is a general computer configuration, and temporarily stores information from the receiving node 10 and data from the operation process, such as a CPU 110 as an arithmetic processing means, an HDD storing an OS, an auxiliary storage device 111 such as an SSD, And a communication function means 113 for communicating with the reception node 10 through the in-system network NW.

  The power switching control unit 12 may not be an independent device, but may be a functional unit included in the processing device 11. It receives power from a corresponding power source PS including a renewable energy source, and stores it in the small storage battery 120. The small storage battery 120 is, for example, a power receiving battery having a usable storage capacity of about 10 minutes (a shorter time or a longer time can be considered depending on system requirements).

  The controller 121 detects the state of the power source PS and the small storage battery 120, determines which power can be used, controls the selector 122 to switch the output of the power source PS or the small storage battery 120, and Supply to The controller 121 simultaneously notifies the CPU 110 of the processing device 11 of control information for the selector 122. Therefore, CPU 110 can identify which of power source PS and small storage battery 120 is supplied with power.

  Based on the configuration example on the side of the information processing nodes P1 to PN, the procedure of the distributed processing will be described as an example based on FIG.

  Here, the receiving node 10 is the receiving node 10 in the embodiment of FIG. 1 described above, or any one receiving node selected from the receiving nodes 101 to 10 n by the user 100 in the configurations of FIGS. 2 and 3. is there. Therefore, in FIG. 4, the reception node 10 will be representatively described and described.

  When information (programs, data, parameters) for information processing is received from the user 100, the information is stored in the shared storage 20.

  Here, in addition to physical storage devices, the shared storage 20 uses distributed storage technology, and data is wholly or fragmented and held in a plurality of processing nodes P1 to PN, thereby making it possible to logically Also includes the case of one large shared storage.

  Next, if the information from the user 100 targets simple scientific and technical calculations, the receiving node 10 notifies each processing node P1 to PN of a job name by multicast and inquires status (step S1). ).

  Each of the information processing nodes P1 to PN which has received a status inquiry request through the communication function means 113 calculates the degree of conformity by the CPU 110 (step S2).

  As the adaptability, the availability of the CPU 110, the execution history of the job scheduled to be processed, information on the availability of electric power by renewable energy (power source type), and information on the state of the small storage battery 120 are obtained. The calculation result of the degree of matching is returned to the receiving node 10 as a status corresponding to the notified job name (step S3).

  When the processing node P receives the power supply from the small storage battery 120, it is determined that the power by the renewable energy is not sufficient and the processing requested by the CPU 110 is not possible, and the small storage battery The state of 120 is also included in the calculation of the matching degree and returned to the receiving node 10.

  Receiving node 10, as statuses, from all the information processing nodes P1 to PN, the receiving node 10 selects one information processing node from among processing nodes capable of processing based on the degree of matching in consideration of processing history and the like.

  Here, when one information processing node is selected, the state of the small storage battery 120 included in the degree of matching also becomes an element of prioritizing processing node selection. For example, to preferentially consume renewable energy, priority is given to a processing node that is not in a stored state. The discharge state of the small storage battery 120 means that the power supply by the renewable energy is not sufficient.

  In addition, even if the small storage battery 120 is in a charged state, the priority of the processing node may change due to the difference in the storage amount. For example, in the evening, when the amount of power generation tends to decrease, in order to store power by a node with a small amount of storage, a processing node with a large amount of storage is preferentially used to level the processable nodes after sunset.

  Then, a notification of processing request is sent to the selected node (in the cycle of T1 in FIG. 4, the information processing node P2 is selected) together with necessary information (variable, calculation formula, etc. on the framework) (step S4).

  The information processing node P2 having received the processing request accesses the shared storage 20, reads the program and data, and executes calculation processing based on the variables and calculation formula sent from the receiving node 10 (step S5).

  Next, the information processing node P2 receives the processing result through the network NW by the communication function means 113 and sends it to the node 10 (step S6). Thereby, the user 100 can obtain the result by the target scientific and technological calculation processing.

  Note that, as in the above example, when the target is a simple scientific and technical calculation, the information processing selected without storing information (program, data, parameters) for information processing in the shared storage 20 When requesting processing to a node, the information for the information processing may be sent together.

  Furthermore, when large-scale scientific and technological calculations are required by the user 100, it is necessary to store information (programs, data, parameters) for information processing from the user in the shared storage 20. It is.

  Then, as shown in FIG. 4, it is possible to repeat the processing steps S1 to S6 as many times as necessary to execute information processing (T1, T2...).

  When large-scale big data is handled, the program is once stored in the shared storage 20 or is arranged in the processing nodes P1 to PN. Then, the generated data is stored in the shared storage 20 at a predetermined cycle or at an arbitrary timing, and the processing steps S1 to S6 described in FIG. 4 are repeatedly executed.

  Furthermore, for the Web application, the program and data are arranged from the Web application server to the processing nodes P1 to PN, and based on the request from the Web application user, the receiving node 10 follows the processing steps of FIG. Let PN do the processing.

  As described above, it is possible to effectively use renewable energy based on the concept of sequentially operating the plurality of information processing nodes P1 to PN from the aspect of always operating the plurality of information processing nodes according to the present invention.
