According to Patent Document 1 and the like, it is known that photovoltaic power generation is used for charging a rechargeable vehicle.

Japanese Unexamined Patent Publication No. 11-178237

By the way, photovoltaic power generation has the property that the power generation capacity increases in the daytime and cannot be generated at night, and there is a wave in the power generation capacity throughout the day. Therefore, the surplus power in the daytime is sold to the outside. In recent years, photovoltaic power generation equipment has become widespread, and effective use of this equipment is being considered. When considering a power grid that spans a large number of dwelling units with solar power as the main power supply source, the surplus power generated in the daytime is wasted because there is a wave in the power generation capacity as described above. However, it is not economical to prepare a storage battery having a capacity capable of using all of such surplus power for storage.

Therefore, the present inventor owns a large number of rechargeable vehicles (electric vehicles) by an operating company that constructs a power grid by contracting with each dwelling unit having a solar power generation facility, and uses the battery of this large number of electric vehicles as a storage battery. We considered a mechanism to rent this electric vehicle to users while using it. Even in this case, it is not economical to prepare enough electric vehicles to absorb all the surplus power in the daytime. Therefore, the inventor further considered a mechanism that can suppress surplus electric power by earning charging power for the electric vehicle by encouraging the user to use the electric vehicle.

INDUSTRIAL APPLICABILITY According to the present invention, there is provided a method capable of suppressing surplus electric power of photovoltaic power generation by working with a user who intends to use a rechargeable vehicle.

It is a schematic diagram for demonstrating the business to which this invention is applied. It is a block diagram of the system which implements the method of adjusting the supply and demand balance of electric power of this invention. It is a graph which shows the transition of the power generation capacity and the total power consumption in one day. It is a graph which shows the transition of the usage charge of the electric vehicle in one day. An example of the event database is shown. It is a figure which shows the location of the electric vehicle of a certain area from morning to noon. It is a figure which shows the location of the electric vehicle of a certain area from the evening to the night.

First, the outline of the business to which the present invention is applied will be described. FIG. 1 is a schematic diagram for explaining a business to which the present invention is applied. As shown in FIG. 1, the power grid 1 operated by the business operator conducting this project includes a solar power generation facility 2 installed in a general dwelling unit, a general consumer dwelling unit 3 that consumes electric power, and the business operator. Is connected to the rechargeable electric vehicle 4 (rechargeable vehicle) managed and operated by. It should be noted that the power grid 1 is connected to a preliminary power storage facility 5 for storing power by surplus power, and a power grid 6 of another company for purchasing power or selling surplus power when the power is insufficient. You may.

The business operator purchases electric power from the solar power generation facility 2 installed in the general dwelling unit and provides the purchased electric power to the dwelling unit 3 of the general consumer. In addition, this project provides the purchased electric power to charge the rechargeable electric vehicle 4 managed and operated by the present operator. In this project, the surplus power generated by the imbalance between the power generated in the solar power generation facility 2 that fluctuates during the day, the general power consumption that fluctuates during the day, and the power used for charging is transferred to the electric vehicle 4. By charging, the balance between supply and demand of electricity is adjusted.

The user who owns the photovoltaic power generation facility 2 has a regular contract with the business operator of this project regarding the sale of electric power to the electric power grid 1. For example, they have contracts on how much money to sell electricity per unit for a month or a year.

Consumers who purchase electric power from this power grid 1 have a regular contract regarding the purchase of electric power with the business operator of this project. For example, they have contracts on how much money to buy electricity per unit for a month or a year. The power grid may supply power to large-scale stores, small-scale stores, commercial buildings, and the like.

The user who intends to use the electric vehicle 4 has a contract with the business operator of this project in advance. For example, in addition to the monthly basic charge, there is a contract that when the electric vehicle 4 is actually used, it is used at the usage charge specified by the business operator per hour. The present invention is based on the premise that the usage fee fluctuates, but is not limited to other contract conditions. For example, it does not matter whether or not there is a basic charge, and the usage charge may not be charged according to the time, but may be charged according to the power used.

The electric vehicle 4 may be configured to start charging immediately when parked in a parking lot having a charging facility, or may be configured so that the main server 13, which will be described later, can control the timing of starting charging. May be. Further, when the electric vehicle 4 is parked in the parking lot of the dwelling unit, the electric power may be supplied to the dwelling unit from the battery mounted on the electric vehicle 4.

The electric vehicle 4 assumed by the present invention is a small one- or two-seater electric vehicle 4. The electric vehicle 4 assumed by the present invention is an electric vehicle 4 that is expected to have a mileage of 10 km or less at one time and is suitably used in so-called last one mile or the like. Therefore, it is assumed that the distance that the electric vehicle 4 can travel on one full charge is about 30 km.

This project assumes that residents living within a predetermined distance from a station form one power grid 1 and operate such a power grid 1 for each station. However, it may be configured so that electric power can be transferred from one power grid 1 to another power grid 1. The electric vehicle 4 basically continues to operate in one power grid 1, but does not prevent the electric vehicle 4 from moving between the plurality of power grids 1.

The user who sells the electric power to the electric power grid 1 does not have to conclude a contract to purchase the electric power from the electric power grid 1 or a contract to use the electric vehicle 4. A user who purchases electric power from the electric power grid 1 does not have to conclude a contract to use the electric vehicle 4.

A server for monitoring the electric power supplied to the electric power grid 1 and the electric power supplied from the electric power grid 1 may be provided. This server may be configured to be able to receive information about the electric power supplied to the electric power grid 1 from the detection device installed in the photovoltaic power generation facility 2. Further, the server may be configured to be able to receive information about the electric power received from the electric power grid 1 from the detection device installed in the dwelling unit of the user who purchases the electric power from the electric power grid 1. Further, the server may be configured to be able to receive information on chargeability and chargeable capacity from each of the electric vehicles 4.

FIG. 2 is a block diagram of a system 10 that adjusts the usage charge of the electric vehicle 4 in order to adjust the balance between supply and demand of electric power. As shown in FIG. 2, the system 10 is composed of a main server 13 connected to the user terminal 11 via the network 12 and various databases connected to the main server 13. The main server 13 predicts power generation capacity prediction data that predicts the power generation capacity [W] of the solar power generation facility 2, general power consumption prediction data that predicts general power consumption, and charge prediction that predicts charging power to the electric vehicle 4. Predict the power supply-demand balance based on the data. The main server 13 adjusts the power supply-demand balance between the power generation capacity of the photovoltaic power generation facility 2, the general power consumption, and the charging power to the electric vehicle 4 based on the predicted power supply-demand balance.

Although each power grid 1 may be provided with one main server 13 for adjusting the balance between supply and demand of electric power, it is preferable that a plurality of power grids 1 are collectively provided with one main server 13.

The power generation capacity [W] of the photovoltaic power generation facility 2 can be predicted by a known method. The correlation with the amount of solar radiation for one year is known, and the power generation capacity by solar power can be predicted by using this correlation. Further, the main server 13 can predict the power generation capacity of the area where the photovoltaic power generation facility 2 is provided and the weather forecast of the area.
If the main server 13 is configured to be able to acquire information on the power generation capacity of the photovoltaic power generation facility 2 from the contracted user, the power generation capacity can be predicted in consideration of the past transition of the power generation capacity. ..

For example, general power consumption can be predicted by known methods. Weekly fluctuations, and the correlation between human power consumption behavior and general power consumption throughout weekdays and holidays or the four seasons are known, and general power consumption can be predicted using these correlations. Alternatively, general power consumption can be predicted based on the schedule of annual or monthly events in the area where this project provides the power grid 1.
If the main server 13 is configured to be able to acquire information on power consumption from a contracted user, general power consumption can be predicted in consideration of changes in past power consumption.

The charging power to the electric vehicle 4 can be predicted from the transition of the charging power of the electric vehicle 4 in the past collected by the present business operator. Alternatively, it can be predicted from the number of rechargeable electric vehicles 4 collected by the present operator. One electric vehicle 4 is charged with a constant charging power, but as the number of rechargeable electric vehicles 4 increases, the charging power increases. The main server 13 adjusts the balance between supply and demand of electric power by controlling the charging electric power to the electric vehicle 4.

FIG. 3 is a graph showing the transition of the power generation capacity by solar power generation predicted by the main server 13 on a weekday in a certain summer and the transition of the total power consumption in the day. Here, the total power of the charging power supplied for charging the electric vehicle 4 and the general power consumption supplied to the dwelling unit 3 is referred to as total power consumption. Further, unlike the present invention, FIG. 3 shows the total power consumption, which is the sum of the charging power and the general power consumption used for charging on the premise that the usage fee of the electric vehicle 4 is not changed. Further, the charging power in FIG. 3 shows a prediction of the charging power to be used for charging on the premise that the event described in the second embodiment is not notified.

In the example shown in FIG. 3, the power generation capacity of the photovoltaic power generation facility 2 is large in the daytime, but is 0 [kW] from 0:00 to 6:00 and from 18:00 to 24:00. This is because the photovoltaic power generation facility 2 cannot generate power at night.
On the other hand, total power consumption is predicted to show its first peak from around 7:00 to 9:00, then decline toward after 12:00, gradually increase from around 15:00, and reach a peak around 21:00. To. For example, many people consume a lot of electricity in the dwelling unit 3 between waking up in the morning and leaving the house to go to work or school, but since few people stay at home in the daytime, the power consumption in the dwelling unit is small. .. In addition, many people return home from evening to night and consume electricity in the dwelling unit 3. Therefore, the total power consumption is predicted to show the transition as shown in FIG.

By the way, in the illustrated example, the power generation capacity of the photovoltaic power generation facility 2 exceeds the general power consumption from about 7:00 to 16:00, and this period is called an excess power generation period. During this excess power generation period from 7:00 to 16:00, it is predicted that there will be a surplus in the power generation capacity of the photovoltaic power generation facility 2. Therefore, the main server 13 sets the usage fee of the electric vehicle 4 so that the electric vehicle 4 can be charged during this excess power generation period.

FIG. 4 is a graph showing changes in the usage fee of the electric vehicle 4. As shown in FIG. 4, in the present embodiment, the main server 13 has one hour (predetermined time) before 7 o'clock (excessive power generation start time) when the power generation capacity of the photovoltaic power generation facility 2 starts to exceed the general power consumption. From 6 o'clock, the usage fee of the electric vehicle 4 is lower than the usage fee up to that point. This is because it is too late to reduce the usage fee after 7 o'clock. The electric vehicle 4 cannot be charged more than fully charged, and the electric vehicle 4 cannot be charged unless the electric vehicle 4 travels and consumes electric power. Therefore, since we want to start charging the electric vehicle 4 at 7 o'clock, we ask the user to actively use the electric vehicle 4 before 7 o'clock and increase the number of rechargeable electric vehicles 4 to increase the charging power. It is secured to a large extent.

As described above, in the present embodiment, when it is predicted that the main server 13 will have an excess power generation period in which the power generation capacity exceeds the total consumption of the charging power and the general power consumption, the power generation capacity is the total consumption. Before the predetermined time of the power generation excess start time when the amount starts to exceed the amount, the usage fee of the electric vehicle 4 is set to be lower than before the change or lower than the standard fee. As a result, the number of electric vehicles 4 that can be charged before the excess power generation period can be increased, the charging power is increased, and the balance between supply and demand of power is adjusted. That is, in FIG. 3, the total power consumption in the period of excess power generation in which the power generation capacity exceeds the total power consumption can be increased, and the total power consumption can be increased to the same level as the power generation capacity.

Unlike the present invention, in a general idea, when trying to utilize all the excess power generation capacity in the daytime, a large number of electric vehicles 4 are operated so that all the excess power generation capacity can be used for charging. Or, a large-scale fixed power storage facility will be installed. However, according to the present invention, it is not necessary to prepare an excessive number of electric vehicles 4 or to provide a large-scale fixed power storage facility. Therefore, the above-mentioned service can be provided to the user at a relatively low cost.

The present invention is not particularly limited to the charge system of the usage charge of the electric vehicle 4. For example, the user can use the electric vehicle 4 at a reference price at any time zone, but may be available at a discount price discounted from this reference price before a predetermined time of the power generation excess start time. Alternatively, set a normal period in which the excess power consumption period that can occur when solar power generation is not possible, such as at night, the above-mentioned excess power generation period, and the generated power and the total power consumption are balanced, and the start time of each period is predetermined. Three different usage charges that are set from the time before may be set. Alternatively, the charge system may be such that the usage charge fluctuates according to the degree of excess power generation capacity. However, the present invention does not apply a charge system that is not on an hourly basis.
Further, the main server 13 is configured to generate cash back in the usage fee of the electric vehicle 4 before a predetermined time of the power generation excess start time, so that the usage fee of the electric vehicle 4 is lowered as a result. May be good.

When the main server 13 changes the usage fee of the electric vehicle 4, the main server 13 may notify the user terminal 11 having a usage contract of the electric vehicle 4 of the change of the usage fee. Alternatively, the usage fee is configured to be always displayed at a specific URL (Uniform Resource Locator), and when the main server 13 changes the usage fee of the electric vehicle 4, the usage fee of the URL is updated. It may be configured as follows.

In the example shown in FIG. 3, the total power consumption is predicted on the premise that the usage fee does not fluctuate, but the present invention is not limited to this. For example, the total power consumption may be predicted and the start time for reducing the usage charge may be determined based on the past charging record and the transition of the set usage charge.

Further, in the above-described embodiment, it has been described that the usage fee of the electric vehicle 4 is set low one hour before the excess start time, but the present invention is not limited to this. For example, it may be set as low as 30 minutes or 2 hours before the excessive start time. Alternatively, the predetermined period before the excess start time may fluctuate throughout the year, such as 2 hours before the excess start time in summer when the power generation capacity is high, and 1 hour before the excess start time in spring, autumn, and winter. May be set to. Alternatively, this predetermined period may be set longer when the excess power generation capacity is predicted to be larger than the predetermined value.

Further, in this example, an example in which the excess start time is set at 7 o'clock has been described, but the excess start time varies through one person. In addition, it varies depending on the weather on the day and weekdays and holidays. Alternatively, the excess start time may change depending on the presence or absence and scale of the event scheduled for the day.

<Second embodiment>
In the first embodiment described above, an example in which the usage fee of the electric vehicle 4 is set low in order to increase the number of rechargeable electric vehicles 4 has been described, but the present invention is not limited to this. In the second embodiment described below, in order to increase the number of rechargeable electric vehicles 4, the users of the electric vehicles 4 are notified of various events. By having people participate in the event, the electric vehicle 4 can be used as a means of transportation for the people, and the number of rechargeable electric vehicles 4 can be increased.

For example, the main server 13 announces an event that starts within the overpower generation period when it is predicted that an overpower generation period will occur in which the power generation capacity exceeds the total consumption of the charging power and the general power consumption. The user terminal 11 of the user of the electric vehicle 4 may be notified.

More specifically, the main server 13 is connected to an event database in which event information including at least event identification information, a venue, and a start time that can identify an event is recorded. Further, the user who has signed the usage contract of the electric vehicle 4 consents to the acquisition of the user's current position through the user terminal 11. Therefore, the main server 13 is configured to be able to periodically grasp the current position of the user through the user terminal 11.

The main server 13 starts from the event database a predetermined time before the power generation excess start time when it is predicted that the power generation capacity will exceed the total consumption of the charging power and the general power consumption. Extract event information to be performed. Further, the main server 13 identifies a user who is within a predetermined distance from the venue of the extracted event information from the current position of the user acquired from the user terminal 11. Notify the extracted event information to the user terminal 11 of the specified user.

FIG. 5 is an example of an event database. For example, in the above-mentioned example, on the day predicted by the main server 13, the period from 7:00 to 16:00 is the power generation excess period. Therefore, the main server 13 extracts the event ID (event identification information): 1 to 4 started within the power generation excess period as the event information to be notified.

Further, the main server 13 specifies a place where the event of the event ID: 1 to 4 is held, and specifies a user located within a predetermined distance from each holding place. The corresponding event information is notified to the user terminal 11 of the specified user. The main server 13 may be configured to notify the event information a predetermined time before the start time of the event. Alternatively, the main server 13 may be configured to notify the event information when it is determined that the user has entered within a predetermined distance from the venue.
As event information, the main server 13 may notify the event name recorded in the event database and the URL where the homepage operated by the event organizer is displayed.

<Modification 1>
In the present invention, in order to actively encourage the use of the electric vehicle 4 for commuting to work or school, the electric vehicle 4 gathers around the station 20 from morning to noon as shown in FIG. 6, and the electric vehicle 4 gathers around the station 20 as shown in FIG. It is assumed that the electric vehicle 4 will disappear from the vicinity of the station 20. If the electric vehicle 4 is continuously parked around the station 20 in the daytime without being used, it becomes difficult to secure a large number of electric vehicles 4 in a rechargeable state. Therefore, with the following configuration, even if the electric vehicles 4 are concentrated and parked around the station 20 in the daytime, it is possible to secure a large number of electric vehicles 4 in a rechargeable state.

The main server 13 divides the user who uses the electric vehicle 4 into a first-class user who reciprocates for a long time such as commuting to work or school and a second-class user who reciprocates in a short time such as a courier. It is configured to be able to access the user database registered separately. Further, the main server 13 is configured to be able to acquire the position information from the electric vehicle 4.
For example, a user whose interval of using a station in a day is 6 hours or more is defined as a first-class user. For example, a user who intends to use the electric vehicle 4 from the vicinity of the home to the station at 7:00 am and to use the electric vehicle 4 from the station to the vicinity of the home at 18:00 in the evening is set as a first-class user.
On the other hand, a user whose interval of using a certain station is 2 hours or less is defined as a second-class user. For example, a user who uses an electric vehicle 4 to go around a residential area from a station at 11:00 in the morning to deliver pizza and plans to return the electric vehicle 4 to the station one hour later is regarded as a second-class user. Set.

When the number of electric vehicles 4 parked in the vicinity of public transportation such as the station 20 exceeds a predetermined number or exceeds a predetermined ratio with respect to the total number of electric vehicles 4, the main server 13 sets a predetermined ratio. When it is predicted that the usage fee will be exceeded, the usage fee for the first-class user will be higher than before, and the usage fee for the second-class user will be lower than before.

The electric vehicle 4 is configured to periodically notify the main server 13 of its current location. The main server 13 can grasp the location of the electric vehicle 4. Based on such position information of the electric vehicle 4, the main server 13 can grasp the uneven distribution of the electric vehicle 4.
For example, when 50 electric vehicles 4 are gathered within a range of 300 m from A station, the main server 13 raises the usage fee for the first-class user located within 800 m from A station. The usage fee for Type 2 users located within 800m from Station A will be lower than before.

The first-class user takes the behavior of heading from the residential area to the station 20 in the morning and returning from the station 20 to the residential area in the evening. In order to provide the electric vehicle 4 to such a first-class user, it is necessary that a certain number or more of the electric vehicles 4 are parked around the station 20 in the daytime. However, it cannot be charged while parked at the station 20.
By the way, the second-class user is a courier company such as a courier company or a pizza delivery company. Unlike the first-class user, such a second-class user takes an action pattern of starting from a base around a certain station 20 and returning to that base again. Therefore, if the second-class user positively uses the electric vehicle 4 in the daytime, the number of the electric vehicles 4 in the rechargeable state can be greatly increased.

Further, it is preferable that the activity base of the second-class user (in the case of pizza delivery, the location of the store) is registered in this user database. The main server 13 is close to the activity base based on this user database, regardless of the current location of the second-class user, when the electric vehicles 4 are parked or expected to be parked in the vicinity of the activity base. It is possible to identify a second-class user and set a low usage fee.

Although the embodiments of the present invention have been described above, it goes without saying that the technical scope of the present invention should not be construed as being limited by the description of the present embodiments. It is understood by those skilled in the art that the present embodiment is merely an example, and various embodiments can be modified within the scope of the invention described in the claims. The technical scope of the present invention should be determined based on the scope of the invention described in the claims and the scope thereof.
