  The power grid data storage unit 102 holds power grid data. Hereinafter, an example of power system data will be described with reference to the drawings.

  FIG. 2 shows an example of a power system diagram in which power system data in a certain region is diagrammed. As shown in the power system diagram 200, the power distribution system L1 includes, for example, a substation TR203, a storage battery BT204, a switch CB205, a branch point N206, a solar power generator PV207, a wind power generator WT208, a voltage regulator (hereinafter referred to as “SVR”). (Referred to as “Step Voltage Regulator”) 209 and a voltage regulator (hereinafter referred to as “SVC (Static Var Compensator)”) 210 are installed.

  The substation TR203 converts the voltage of the upstream (power plant side) power system into a voltage suitable for the downstream (customer side) power distribution system. The storage battery BT 204 is charged with electric power (hereinafter referred to as “supplied power”) supplied from the power plant to the consumer through the electric power system, and is discharged to compensate for the shortage. The switch CB205 switches the distribution system line when maintenance or failure occurs in the distribution line. The branch point N206 branches the distribution system line. The solar power generator PV207 generates power by receiving sunlight. The wind power generator WT208 generates power by receiving wind power. The solar power generator PV207 and the wind power generator WT208 are also called distributed power sources. The electric power generated by the distributed power source such as the solar power generator PV207 or the wind power generator WT208 is also supplied to consumers through the power distribution system line. The SVR 209 adjusts voltage fluctuations in the power distribution system using mechanical taps. The SVC 210 electrically adjusts voltage fluctuations in the distribution system.

  The facility arrangement support apparatus 101 according to the present embodiment assists in arranging an electric vehicle charging facility (hereinafter referred to as “EVC”) at an appropriate position of the power distribution system L1. The EVC is a facility for charging a battery of an electric vehicle (hereinafter referred to as “EV (Electric Vehicle)”) that uses electric power as a drive source. EVCs can be installed in various places such as streets and roadsides like current gas stations. Furthermore, the EVC can be installed in a parking lot of a facility. The electric vehicle can stop at the EVC and charge the battery.

  FIG. 3 shows an example of power system data in a certain area. The power system data 400 includes a substation area capacity 402, a bank capacity 403, and a feeder capacity 404 that are set for each hierarchy from upstream to downstream of the distribution line 401.

  The power system data 400 includes a device model ID 405 that can uniquely identify a device installed on the distribution line 401, a position 406 where the device is installed, and various attribute information related to the device. The power system data has, for example, a primary side (upstream side) voltage 407 as first attribute information, and a secondary side (downstream side) voltage 408 as second attribute information. Note that the power system data 400 illustrated in FIG. 3 is merely an example, and information regarding various power systems may be held. Returning to the description of FIG.

Based on the power system data held in the power system data storage unit 102, the power system analysis unit 104 can still supply power (that is, surplus power) that can still be supplied to the supplied power in a certain section of the distribution line 401. The power margin is calculated by analyzing the amount of power. For example, the power system analysis unit 104 calculates the power margin as follows.
1) Read power system data for a predetermined period in the past from the power system data storage unit 102.
2) Based on the power system data in a predetermined period or period in the past, the power flow in a certain section of the distribution line 401 is calculated, and the amount of power demand in a predetermined period or period is predicted.
3) The power margin is calculated based on the difference or ratio between the power supply amount and the demand power amount in a predetermined time zone or period of a certain section of the distribution line 401. Hereinafter, an example of a method for calculating the power margin will be described with reference to the drawings.

  FIG. 4 is a graph showing power fluctuations in a predetermined time zone in a certain section of the power system. In the graph 1000 illustrated in FIG. 4, the horizontal axis represents time, and the vertical axis represents power. That is, the curve 1001 shows the power value at a certain time. From the power transition of the curve 1001, the average power 1004 in a certain time zone can be calculated. Further, the peak power 1003 in a certain time zone can be calculated from the maximum value of the power of the curve 1001. The rated power 1002 is defined in advance in the section.

  For example, the power margin may be calculated as a difference 1005 (or ratio) between the rated power 1002 and the peak power 1003. Alternatively, the power margin may be calculated as a difference (or ratio) between the rated power 1002 and 80% of the peak power 1003. Alternatively, the power margin may be calculated as a 20% increase in the average power 1004. It is assumed that the power margin according to the present embodiment has a power margin as the value increases. However, it goes without saying that the smaller the value of the power margin, the better the power. Returning to the description of FIG.

  Based on the power margin calculated by the power system analysis unit 104, the power margin superimposing unit 105 explicitly indicates how much power margin is present in which section of the distribution system L1. To display. Hereinafter, an example of the display of the power margin superimposing unit 105 will be described with reference to the drawings.

  FIG. 5 shows an example of display in the power margin superimposing unit 105. For example, as illustrated in FIG. 5, the power margin superimposing unit 105 displays a power system diagram 200 on which information related to the power margin is superimposed on the output device 113. That is, the power margin superimposing unit 105 explicitly displays the power margin of each section in a manner that can be visually distinguished. For example, the power margin superimposing unit 105 displays a section with a relatively high power margin in a color with a high density, and displays in a color with a low density as the power margin decreases. In FIG. 5, sections 702 and 703 with relatively high power margin are displayed in a color with high density, and sections 704 to 706 with lower power margin than section 702 are displayed in a color with low density.

  The power margin superimposing unit 105 may display only a section that is greater than or less than the specified power margin. The power margin superimposing unit 105 may also display the power margin value. The power margin superimposing unit 105 displays a GUI (Graphical User Interface) for selecting a display target (for example, a section where the power margin is equal to or greater than the predetermined value A) on the output device 113, and is selected from the GUI. Only a section may be displayed with a color. Returning to the description of FIG.

  The vehicle route data input unit 107 acquires vehicle route data in a predetermined area from the vehicle route database 115 via the communication network 123. The vehicle route data input unit 107 registers the acquired vehicle route data in the vehicle route data storage unit 106.

  The vehicle route data storage unit 106 holds vehicle route data. Hereinafter, an example of the vehicle route data will be described with reference to the drawings.

  FIG. 6 shows an example of a vehicle route map in which vehicle route data in a certain area is diagrammed. As shown in the vehicle route map 300, the area includes, for example, a plurality of large-scale roads BL302, a plurality of medium-scale roads ML303, a plurality of small-scale roads SL304, and the like. In the area, there are a housing HS305, a shopping mall SM306, a convenience store CS307, a factory FY308, a hospital HP309, and the like. These facilities become electricity consumers.

  FIG. 7 shows an example of vehicle route data in a certain area. The vehicle route data 500 includes, as data items, a route model ID 501 that can uniquely identify the elements 302 to 309 existing in the vehicle route map 300, the element type 502, the position 503 of the element, and the scale of the element. 504 and other attribute information.

  For example, in the record 511 of the vehicle route data 500, the element whose route model ID is “BL1” is a large-scale road and is located at coordinates (x1, y1), (x1 ′, y1 ′),. The scale indicates that it is a single lane with a width of 32m. Returning to the description of FIG.

  Based on the vehicle route data stored in the vehicle route data storage unit 106, the geographical convenience analysis unit 108 determines how much the convenience of the EV is improved when the EVC is arranged (hereinafter referred to as “geographic convenience”). ”). The geographical convenience analysis unit 108 calculates the geographical convenience of a certain position in a predetermined area. The geographical convenience is calculated based on, for example, route information related to the traffic volume of a route around the location and facility information related to facilities around the location. The route information includes, for example, information such as route scale or road width. The facility information includes information such as the size and type of facilities such as shopping malls, convenience stores, and hospitals, the presence / absence of a parking lot, and the ability to attract customers.

  For example, when there is a route with a large amount of traffic in the vicinity and there is a facility with high ability to attract customers, the geographical convenience at that position is calculated to be high. This is because there is a high possibility that many EVs will visit. For example, when there is a facility with high customer attraction in the vicinity and a parking lot is fully equipped, the geographical convenience of the location is calculated to be high. This is because the convenience of EV increases if charging is possible while parking in the parking lot.

  When the geographical convenience analysis unit 108 calculates the geographical convenience of a certain position, the geographical convenience analysis unit 108 may calculate the geographical convenience of another position according to the distance from the position. For example, you may make it the geographical convenience of the position become low, so that it is far from the position with high geographical convenience. The geographical convenience analysis unit 108 may calculate a high degree of geographical convenience in the vicinity when a specific condition or the like is satisfied. For example, when no EVC exists near the entrance / exit of an expressway or within a predetermined radius of several tens of kilometers, the geographical convenience of the position may be calculated high.

  Based on the geographical convenience calculated by the geographical convenience analysis unit 108, the geographical convenience superimposing unit 109 can visually recognize how much the convenience of the EV is improved when the EVC is installed at which location. Display explicitly in the form. Hereinafter, an example of the display of the geographical convenience superimposing unit 109 will be described with reference to the drawings.

  FIG. 8 shows an example of display in the geographic convenience superimposing unit 109. For example, as shown in FIG. 8, the geographical convenience level superimposing unit 109 displays a vehicle route map 300 on which information related to the geographical convenience level is superimposed on the output device 113. That is, the geographic convenience superimposing unit 109 explicitly displays the geographical convenience level of each part in a visually distinguishable manner. For example, the geographical convenience level superimposing unit 109 displays a position having a relatively high geographical convenience level in a color with a high density, and displays in a color with a lower density as the geographic convenience level becomes lower. In FIG. 8, a position 802 having a relatively high geographical convenience is displayed in a color with a high density, and a position 804 having a lower geographical convenience than the position 802 is displayed in a color with a low density.

  Note that the geographic convenience superimposing unit 109 may display only a position that is greater than or less than the designated geographic convenience. The geographical convenience superimposing unit 109 may also display the geographical convenience value together. The geographic convenience superimposing unit 109 displays a GUI for selecting a display target (for example, a location where the geographic convenience is A or higher) on the output device 113, and colors only the positions selected from the GUI. You may attach and display. Returning to the description of FIG.

  The integration processing unit 110 displays both the power system diagram 200 on which the power margin is superimposed and the vehicle route map 300 on which the geographical convenience is superimposed on the same or different output devices 113. The integration processing unit 110 receives an instruction for placement on the EVC at a desired position in the power system diagram 200 or the vehicle route map 300 from the user via the input device 112. That is, the user can place an EVC at a desired location on the power system diagram 200 or the vehicle route map 300 via the input device 112. When the EVC is arranged at a certain location, the integration processing unit 110 recalculates the power margin including information on the power of the EVC (for example, battery capacity and rated power). Similarly, the integrated processing unit 110 recalculates the geographical convenience including the geographical information (for example, the surrounding road size and facility size) where the EVC is located. Then, the integrated processing unit 110 redisplays both the power system diagram and the vehicle route map reflecting the result of the recalculation on the output device 113. The above process will be further described with reference to the drawings.

  FIG. 9 shows an example of integrated display in the integrated processing unit 110. For example, as illustrated in FIG. 9, the integration processing unit 110 displays a power system diagram 601 on which a power margin is superimposed and a vehicle route map 602 on which a geographic convenience is superimposed.

  The user can know that the power margins of the sections 702 and 703 are relatively high with reference to the power system diagram 601 of FIG. Therefore, the user arranges the EVC 212 a in the section 702 and the EVC 212 b and the EVC 212 c in the section 703. When such an operation is performed, the integrated processing unit 110 displays the EVC 222a at a position on the map corresponding to the section 701 of the power system in the vehicle route map 602, and on the map corresponding to the section 703 of the power system. The EVC 222b and the EVC 222c are displayed at the positions.

  Alternatively, the user can know that the geographical convenience of the position 802 is relatively high and the geographical convenience of the position 803 is high next with reference to the vehicle route map 602 of FIG. Therefore, the user arranges the EVC 222b and the EVC 222c at the position 802, and arranges the EVC 222a at the position 801. When such an operation is performed, the integrated processing unit 110 displays the EVC 212b and the EVC 212c in the section 703 on the power system corresponding to the position 802 on the map in the power system diagram 601, and corresponds to the position 803 on the map. The EVC 212a is displayed in the section 702 on the power system to be operated.

  When EVC is arrange | positioned, the integrated process part 110 may display again the density | concentration of the area on the electric power system by which EVC is arrange | positioned, and / or the position on a map low. An example of such case will be shown below.

  FIG. 10 shows an example of the integrated display after the EVC is arranged. FIG. 10 is an example of the integrated display when the recalculation button 610 is pressed after the EVC is arranged in FIG.

  In the power system diagram 601 of FIG. 10, the color density of the section 702 in which the EVC 212a is arranged is light. This is because the power margin of the section 702 is reduced by the arrangement of the EVC 212a. The section 703 where the EVCs 212b and 212c are arranged is not colored. This is because the power margin of the section 703 is almost lost due to the arrangement of the EVCs 212b and 212c.

  Further, in the vehicle route map 602 of FIG. 10, the color density at the position 803 where the EVC 222a is disposed is light. This is because the geographical convenience of the position 803 is reduced by arranging the EVC 212a. Further, the positions 802 where the EVCs 212b and 212c are arranged are not colored. This is because the geographical convenience of the position 802 is almost lost due to the arrangement of the EVCs 212b and 212c. In other words, even if EVC is installed, the convenience of EV is hardly improved.

  Further, in the power system diagram 601 of FIG. 10, a BT 204a is newly added. This is because, when the EVCs 212b and 212c are installed in the section 703, the power margin is insufficient, so the integrated processing unit 110 proposes the installation of the BT 204a. That is, the facility arrangement support apparatus 101 performs power flow calculation including the EVC arranged by the user, and when there is a problem with the stability of the power system (for example, when the supplied power is insufficient), the power system A device for stabilizing the battery (for example, storage battery BT) and its arrangement position may be proposed.

  FIG. 11 shows a modified example of the integrated display in the integrated processing unit 110. FIG. 11 is a superimposed diagram 1300 in which the power margin and the geographical convenience are superimposed on the vehicle route map 300.

  For example, the user can know that the positions 1301 to 1303 are both relatively high in power margin and geographical convenience with reference to the superimposed diagram 1300. Therefore, the user arranges EVC 222 a at position 1301, EVC 222 b at position 1302, and EVC 222 c at position 1303. The integration processing unit 110 automatically arranges the EVC in the section in the power system diagram 200 corresponding to the position where the EVC is automatically arranged.

  11, a position 1301 corresponds to a section 702 in the power system diagram 200 of FIG. 5, and positions 1302 and 1303 correspond to a section 703 in the power system diagram 200 of FIG. Therefore, the integration processing unit 110 arranges the EVC 222a arranged at the position 1301 in the section 702 in the power system diagram 200 of FIG. 5 and recalculates the power margin. The same applies to the EVCs 222b and 222c.

  Note that the integrated processing unit 110 may display the power margin and the geographical convenience superimposed on the power system diagram 200 shown in FIG. The integration processing unit 110 may enlarge and display a predetermined area of the superimposed diagram based on a user operation. The integrated processing unit 110 may switch and display the drawing shown in FIG. 9 and the drawing shown in FIG. 11 based on a user operation. The integrated processing unit 110 may display (colored or the like) such that only sections having a power margin greater than or equal to a predetermined value can be distinguished. The integrated processing unit 110 may display in a manner in which only positions having a geographical convenience level equal to or greater than a predetermined value can be distinguished. The integrated processing unit 110 may display the power margin and the geographical convenience in a manner in which only the section and / or position where the power margin and the geographical convenience are equal to or greater than a predetermined value can be distinguished.

  FIG. 12 shows a flowchart of processing of the facility arrangement support apparatus. The user designates the area where the EVC placement plan is to be performed in the equipment placement support apparatus 101 (S101).

  In response to this, each of the power system analysis unit 104 and the geographical convenience analysis unit 108 reads each of the power system data and vehicle route data of the designated area (S102). Here, when the power system data of the designated area does not exist in the power system data storage unit 102, the power system data of the designated area is acquired from the power system database 114 through the power system data input unit 103. Similarly, when the vehicle route data of the designated area does not exist in the vehicle route data storage unit 106, the vehicle route data of the designated region is acquired from the vehicle route database 115 through the vehicle route data input unit 107.

  The power system analysis unit 104 calculates the power margin in the area, and the geographical convenience analysis unit 108 calculates the geographical convenience in the area (S103).

  The power margin superimposing unit 105 generates a power system diagram on which the power margin is superimposed, and the geographical convenience superimposing unit 109 generates a vehicle route map on which the geographical convenience is superimposed (S104).

  The integration processing unit 110 displays both the power system diagram on which the power margin is superimposed and the vehicle route map on which the geographical convenience is superimposed (S105).

  The user arranges the EVC at a desired position while referring to the integrated display screen (S106).

  When the recalculation button is pressed (S107: YES), the integration processing unit 110 adds the characteristics of the arranged EVC and recalculates the power margin and the geographical convenience (S108).

  The integration processing unit 110 integrally displays the power system diagram and the vehicle route map reflecting the power margin after recalculation and the geographical convenience (S109).

  The integration processing unit 110 determines whether there is a problem with the stability of the power system after recalculation (S110).

<Second Embodiment>

  FIG. 13 shows a configuration of a power supply system according to the second embodiment. Note that the same components as those in FIG. 1 are denoted by the same reference numerals and description thereof is omitted.

  A power supply system 2000 shown in FIG. 13 includes a facility arrangement support apparatus 2001 and a power supply apparatus 116 that supplies power to a power system in a predetermined area, and these are communication networks 124 capable of bidirectionally transmitting and receiving data. Connected by. In addition to the elements 102 to 110 shown in FIG. 1, the facility arrangement support apparatus 2001 calculates the power to be supplied to the power system when the EVC arranged in the integrated processing unit 110 is included. Part 111 is provided.

  Based on the information on the position and power of the EVC arranged in the integrated processing unit 110 (for example, battery capacity, rated power, etc.) and the like, the supplied power calculation unit 111 determines the power system in a predetermined area where the EVC is arranged. The power to be supplied by the power supply device 116 (hereinafter simply referred to as “power to be supplied”) is calculated. The supplied power calculation unit 111 instructs the power supply device 116 via the communication network 124 to supply the calculated power to be supplied.

  The supplied power calculation unit 111 may calculate the power to be supplied based on the high degree of geographical convenience. This is because it can be assumed that EVC installed at a location with high geographical convenience is used more (electric power is consumed).

According to the present embodiment, when an EVC is actually installed at a position simulated by the facility arrangement support apparatus 2001, the power to be supplied to the power supply apparatus 116 is appropriately determined using the power to be supplied calculated by the simulation. Can be directed to. That is, the power supply system 2000 provided with the facility arrangement support apparatus 2001 can stably operate the power system in which the EVC is installed.
<Third Embodiment>

  In the third embodiment, a method for calculating the above-described geographical convenience will be described in detail. The system configuration according to this embodiment is the same as that shown in FIG.

  FIG. 14 shows a modification of the vehicle route data in a certain area. The vehicle route data 500a shown in FIG. 14 has a geographical score 505 as one of the attribute information of the vehicle route data 500 shown in FIG.

  The geographic score 505 indicates the level of convenience when an EVC is installed around a road or facility indicated by the route model ID 501 (hereinafter simply referred to as “facility etc.”). The geographic score 505 may be a negative value as well as a positive value. When the geographical score 505 is a positive value, the convenience of EV is improved by installing the EVC around the facility or the like. Conversely, when the geographical score 505 is a negative value, the convenience of EV is not improved so much even if an EVC is installed around the facility. For example, as shown in the record 521n in FIG. 14, the geographical score 505 of the EVC is a negative value. This is because, as described above, when an EVC has already been installed, the convenience of the EV is not greatly improved even if an EVC is further installed around the EVC.

  The geographical convenience is calculated using this geographical score 505. The geographical convenience is calculated by the following formula 1, for example.

  Here, P is the position for calculating the geographical convenience, F (P) is the geographical convenience at the position P, p is the position of the facility, etc., S (p) is the geographical score 505 of the facility at the position p, N (N is a positive integer) indicates the number of facilities or the like existing around the position P. In other words, Equation 1 weights the geographical score F (P) of the facility or the like existing at the position p so that the geographical score S (p) at the position P decreases as the distance from the position P increases. , It is calculated that all facilities existing around the position P are calculated in total.

  Therefore, the geographical convenience F (P) is calculated based on the number of facilities and the like existing around the position P and the geographical score 505 (any positive or negative value can be taken) of each facility or the like. The

  Note that the above formula 1 may be applied by limiting the periphery of the position P to a predetermined distance from the position P. For example, the periphery from the position P may be limited to a radius of 10 km, and only the facility or the like existing within the radius may be the application target of the above formula 1.

  Through the above processing, the geographical convenience analysis unit 108 can calculate the geographical convenience at a predetermined position P in a predetermined area.

  The above-described embodiments of the present invention are examples for explaining the present invention, and are not intended to limit the scope of the present invention to these embodiments. Those skilled in the art can implement the present invention in various other modes without departing from the gist of the present invention.
