Detailed Description
(first embodiment)
Fig. 1 shows a battery electric propulsion boat power supply system 1 according to a first embodiment of the invention. The power supply system 1 includes a plurality of battery electric propulsion vessels 2, a plurality of offshore power generation vessels 3 (corresponding to offshore power supply equipment of the present invention), and a management device 5. However, the number of battery electric propulsion vessels 2 may be 1, and the number of offshore power generation vessels 3 may be 1.
In fig. 1, the power supply system 1 is constructed for one bay 11 including two ports 12 and 13, but the power supply system 1 may be constructed across a plurality of bays.
In the present embodiment, each battery electric propulsion ship 2 is an internal ship that sails in the domestic sea area. The domestic sea area may be a japanese domestic sea area or a foreign domestic sea area. Alternatively, in the case of multi-country adjacency, the domestic sea area may be a domestic sea area of these countries. The electric propulsion ship 2 may be an outboard ship which is engaged in an international sea voyage.
For example, the electric propulsion boat 2 is a tug, a ferry, various kinds of logistics boats (container ships, oil ships, general cargo ships, chemical ships), or the like. For example, tugs perform actions to pull large vessels; the container ship performs the act of transporting containers between ports. The actions of the electric propulsion ship 2 are changed every day for each battery.
Specifically, although not shown, each of the battery electric propulsion vessels 2 includes a propeller drive motor that drives a propeller, and a battery that supplies electric power to the propeller drive motor. The secondary battery is charged by being connected to a power supply device described later of the offshore power generation vessel 3.
Each offshore power generation vessel 3 is a vessel capable of generating power from liquefied gas and charging a storage battery of the battery electric propulsion vessel 2. Liquefied gas is, for example, LNG (Liquefied Natural Gas ), liquefied hydrogen, or the like. In the present embodiment, each offshore power generation vessel 3 supplies power to each battery electric propulsion vessel 2 to charge the storage battery of the battery electric propulsion vessel 2. However, the charging of the secondary battery of the battery electric propulsion boat 2 does not have to be performed on the battery electric propulsion boat 2. For example, the battery for exchange may be charged on the offshore power generation vessel 3 during the sailing of the battery electric propulsion vessel 2, and the battery of the battery electric propulsion vessel 2 may be exchanged with the battery after the charging is completed when the battery electric propulsion vessel 2 is moored to the offshore power generation vessel 3.
Specifically, although not shown, each offshore power generation vessel 3 includes a tank for storing liquefied gas, an internal combustion engine for combusting the liquefied gas or gasified gas thereof, a generator connected to the internal combustion engine, a storage battery for storing electric power generated by the generator, and a power supply device connected to the storage battery.
The internal combustion engine of each offshore power generation vessel 3 may be a piston engine or a gas turbine engine. Alternatively, a gas boiler and a steam turbine may be used instead of the internal combustion engine. In the case where the liquefied gas is liquefied hydrogen, each offshore power generation vessel 3 may include a fuel cell for generating electricity by reacting hydrogen and oxygen.
In the present embodiment, the power supply system 1 further includes a plurality of liquefied gas supply devices 4 installed on land. Each liquefied gas supply device 4 supplies liquefied gas to any offshore power generation vessel 3. For example, each liquefied gas supply apparatus 4 includes a plurality of large-capacity tanks for storing liquefied gas.
In fig. 1, two liquefied gas supply units 4 are provided at ports 12, 13, respectively, and one liquefied gas supply unit 4 is provided at a wall of the shore instead of the port. In the vicinity of these liquefied gas supply devices 4, the offshore power generation vessel 3 is moored to the shore.
On the other hand, there is also an offshore power generation vessel (the offshore power generation vessel 3 located at the lowest position in fig. 1) disposed at a position distant from the shore. The offshore power generation vessel 3 may be anchored in this position or may be held in this position by a propeller without using anchors. The liquefied gas is supplied to the offshore power generation vessel 3 by exchanging the offshore power generation vessel 3 with another offshore power generation vessel 3.
The management device 5 is installed on land in the present embodiment, but may be installed on a floating type offshore base, for example. Alternatively, the management device 5 may be mounted on any offshore power generation vessel 3. The management device 5 may be mounted on each of the plurality of battery electric propulsion vessels 2 or the offshore power generation vessel 3. The management devices 5 mounted on the ships construct an information sharing system that shares information with each other, and the ships on which the management devices 5 are mounted may have a structure that autonomously manages information based on the shared information.
The management device 5 can communicate with the battery electric propulsion vessel 2 and the offshore power generation vessel 3. Although not shown, each battery electric propulsion ship 2 includes a communication device and a processing device in addition to the above-described configuration. Similarly, each offshore power generation vessel 3 and management device 5 also includes a communication device and a processing device. For example, the processing device is a computer having an internal memory such as ROM and RAM, a hard disk memory such as HDD, and a CPU, and a program stored in the ROM or HDD is executed by the CPU.
The operator of each battery electric propulsion ship 2 inputs the behavior information of the battery electric propulsion ship 2 to the processing device every day. The action information includes the port and time of departure, port and time of arrival, and action content.
The communication device of each battery electric propulsion ship 2 transmits the action information inputted to the processing device as navigation data to the management device 5. The communication device of each battery electric propulsion ship 2 also transmits the capacity of the storage battery of the battery electric propulsion ship 2 and the remaining battery power to the management device 5 as navigation data. The navigation data may include a propulsion power load of each battery electric propulsion ship 2, an inboard power load other than propulsion, a ship speed, and the like.
The communication device of each battery electric propulsion ship 2 may transmit the operation state data of the battery, the propeller drive motor, and the propeller to the management device 5 together with the navigation data of the battery electric propulsion ship 2.
The navigation data transmitted from each battery electric propulsion ship 2 is received by the communication device of the management device 5. The processing device of the management device 5 determines an optimal standby position at which each offshore power generation vessel 3 supplies power to all the battery electric propulsion vessels 2 based on the navigation data of each battery electric propulsion vessel 2. The communication device of the management device 5 transmits the standby position of each offshore power generation vessel 3 determined by the processing device to each offshore power generation vessel 3.
The standby position transmitted from the management device 5 is received by the communication device of each offshore power generation vessel 3, and is output to a monitor or the like by the processing device. The operator of each offshore power generation vessel 3 moves the offshore power generation vessel 3 to the standby position.
The processing device of the management device 5 determines the charging schedule of each battery electric propulsion ship 2 based on the navigation data of all battery electric propulsion ships 2. The charging schedule contains a particular determination of the moment of charging and the offshore power generation vessel 3 that should receive charging. The communication means of the management device 5 send the charging schedule of each battery electric propulsion ship 2 determined by the processing means to the corresponding battery electric propulsion ship 2.
The charging schedule transmitted from the management device 5 is received by the communication device of each battery electric propulsion ship 2, and is output to a monitor or the like by the processing device. The operator of each battery electric propulsion vessel 2 operates the battery electric propulsion vessel 2 in a manner that receives charge from a specially determined offshore power generation vessel 3 during the course of the action, following the charging schedule.
The processing device of the management device 5 obtains marine weather data including wave information and wind information from an external organization such as a weather hall via a network or the like. The processing means then determines, based on the marine meteorological data, whether or not power can be supplied from the offshore power generation vessel 3 to the battery powered propulsion vessel 2.
In the power supply system 1 having the above-described configuration, the battery electric propulsion boat 2 may be charged at sea without being tethered to the shore, and the rechargeable battery of the battery electric propulsion boat 2 may be charged.
In the present embodiment, the management device 5 determines the standby position where each offshore power generation vessel 3 supplies power to all the battery electric propulsion vessels 2 optimally, and therefore the offshore power generation vessel 3 can be moved to the standby position. This can reduce the distance each battery electric propulsion boat 2 travels for charging.
In the present embodiment, since the management device 5 determines the charging schedule of each battery electric propulsion boat 2, each battery electric propulsion boat 2 can receive charging in compliance with the charging schedule. Therefore, each battery electrically propels the ship 2 effectively.
(modification)
The present invention is not limited to the above-described embodiments, and various modifications are possible within a range not departing from the spirit of the present invention.
For example, the offshore power generation facility of the present invention is not necessarily the offshore power generation vessel 3 that generates power by using liquefied gas, but may be a floating type power generation facility that generates power by offshore wind power and is fixed at a predetermined position. However, if the offshore power plant is the offshore power generation vessel 3 as in the above embodiment, the position of the offshore power plant may be changed according to circumstances. In addition, in the case of the offshore power generation vessel 3 that generates power by using liquefied gas, it is possible to cope with recent severe environmental regulations, unlike the case of using oil such as heavy oil as fuel.
The liquefied gas is not necessarily supplied from the liquefied gas supply unit 4 on land to the offshore power generation vessel 3, but may be supplied from a liquefied gas supply unit on the sea. Examples of such offshore liquefied gas supply devices include floating liquefied gas bases and liquefied gas carrier vessels. However, if the liquefied gas is supplied from the liquefied gas supply apparatus 4 on land to the offshore power generation vessel 3 as in the above-described embodiment, since a plurality of large-capacity tanks for storing the liquefied gas are generally provided in the liquefied gas supply apparatus 4 on land, the liquefied gas can be stably supplied to the offshore power generation vessel 3 when the liquefied gas is required.
The management device 5 may execute a ship dispatch plan for all the electric propulsion ships 2 on a daily basis based on the navigation data of all the electric propulsion ships 2, determine a navigation schedule including actions for each electric propulsion ship 2, and transmit the determined navigation schedule to the corresponding electric propulsion ship 2. According to this structure, the ship dispatch plan can be automated.
The management device 5 may determine the standby position of each offshore power generation vessel 3, the charging schedule of each battery electric propulsion vessel 2, and/or the travel schedule of each battery electric propulsion vessel 2 based on the machine learning result of the travel data of all battery electric propulsion vessels 2 and the operation state data of the storage battery, the propeller drive motor, and the propeller. According to this structure, it is possible to minimize the charging time of each battery electric propulsion ship 2, and/or maximize the operation efficiency of each battery electric propulsion ship 2, and/or maximize the life of the storage battery of each battery electric propulsion ship 2.
In the above-described embodiment, the electric propulsion vessels 2 are assumed to be on board of the operator, but the electric propulsion vessels 2 may be unmanned vessels. In this case, the battery electric propulsion boat 2 is automatically operated based on the charging schedule, the travel schedule, and the like transmitted from the management device 5. Similarly, each offshore power generation vessel 3 may be an unmanned vessel.
(second embodiment)
The present inventors have studied in order to achieve the efficiency of the operation cost of the power supply system 1. In recent years, the use of renewable energy sources such as solar power generation has been actively utilized while the use of atomic energy has been greatly restricted. Accordingly, the present inventors have focused on such a land-based power supply apparatus, and studied its applicability.
Fig. 2 is a graph showing an example of the power supply and demand conditions of the land-based power supply apparatus. Here, the power supply and demand conditions on a day in summer are shown. The land power supply facility performs thermal power generation, solar power generation, wind power generation, and hydroelectric power generation, but does not perform atomic power generation. As shown in fig. 2, the land power supply apparatus relies on thermal power generation and solar power generation, so that the land power supply apparatus has a surplus of land power in the daytime (6:00 to 18:00) and a low power price. On the other hand, at night (18:00 to 6:00), land power is insufficient, and the power price of land power supply equipment is high. Accordingly, the inventors have studied a comparison between the power price of the land-based power supply equipment varying according to time and weather conditions and a power price calculated from the unit price of the power generation of the offshore power generation vessel. As a result, it has been found that the running cost of the entire power supply system can be improved by determining which power supply device should be preferentially supplied by the battery electric propulsion vessel based on the navigation data received from the battery electric propulsion vessel, and the power supply price of the offshore power supply device and the power price of the land power supply device.
In order to stably supply the electric power generated in the land power supply facility of fig. 2, it is necessary to continue the operation in the state where the power generation efficiency is highest. On the other hand, if it is assumed that thermal power generation is stopped, there is a problem that necessary electric power cannot be ensured in the case of night where solar power generation cannot be performed or in the case of daytime where expected solar power generation cannot be obtained due to sunlight conditions. Accordingly, the inventors have studied the cost-effectiveness ratio when selling surplus power to land-based power supply equipment, assuming surplus power of an offshore power supply vessel and a battery electric propulsion vessel at the time of system operation. As a result, it has been found that, when the offshore power supply vessel and the battery electric propulsion vessel each have surplus power, they are sold to the land power supply facility according to the power supply price of the offshore power supply facility and the power price of the land power supply facility, whereby the operation cost of the entire power supply system can be further improved.
The present inventors have conceived the present invention based on the above findings. Hereinafter, a specific embodiment of the present invention will be described with reference to the drawings.
In fig. 3 a battery electric propulsion boat power supply system 1A according to a second embodiment of the invention is shown. As shown in fig. 3, the power supply system 1A of the present embodiment is different from the first embodiment in that it includes a land power supply device 20 installed on land (fig. 1). In fig. 3, a land-based power supply device 20 that can charge the secondary battery of the battery electric propulsion ship 2 is provided in the port 13. However, the number of land-based power supply apparatuses 20 may be plural.
The land-based power supply device 20 is, for example, a commercial system. The land power supply facility 20 includes a power supply station 21, a thermal power generation system 22, a solar power generation system 23, a wind power generation system 24, and a hydro power generation system 25. However, the land-based power supply apparatus 20 may also be provided with a power generation system using other natural energy sources. The power supply station 21 is configured to supply power generated by the power generation systems 22 to 25 to the battery electric propulsion boat 2 and to charge the storage battery of the battery electric propulsion boat 2. However, the charging of the secondary battery of the battery electric propulsion boat 2 is not necessarily performed by the electric power supply station 21. For example, the battery for exchange may be charged by the power supply station 21 during the sailing of the electric propulsion boat 2, and the battery of the electric propulsion boat 2 may be exchanged with the battery after the charging is completed when the electric propulsion boat 2 is moored to the port 13. Although not shown, the power supply station 21 includes a communication device and a processing device in addition to the above-described configuration.
In the land power supply facility 20, the battery electric propulsion ship 2 and the offshore power generation ship 3 can sell electricity from the surplus power after the battery is charged. That is, each battery electric propulsion ship 2 is configured to supply surplus electric power to the land power supply apparatus 20 (electric power supply station 21). Also, the offshore power generation vessel 3 is configured to supply surplus power to the land power supply apparatus 20.
The management device 5 is configured to be communicable with the land power supply apparatus 20, and is configured to be able to acquire power price data for each predetermined time of the land power supply apparatus 20 from the land power supply apparatus 20. The management device 5 may receive the power price data directly from the land-based power supply apparatus 20 or may receive the power price data indirectly from other apparatuses through a network.
In the present embodiment, the management device 5 acquires the power price data for each predetermined time of the land power supply facility 20, and compares the power price of the land power supply facility 20 with the power supply price of the offshore power generation vessel 3. The electricity supply price of the offshore power generation vessel 3 is an electricity price calculated from the unit price of the offshore power generation vessel 3. When the power price of the land power supply facility 20 is lower than the power price of the offshore power generation vessel 3, the management device 5 generates a power supply command for preferentially receiving power supplied from the land power supply facility 20 of the offshore power generation vessel 3 and the land power supply facility 20 based on the navigation data received from all the battery electric propulsion vessels 2, and transmits the generated power supply command to each of the battery electric propulsion vessels 2. The power supply command transmitted from the management device 5 is received by the communication device of each battery electric propulsion ship 2, and is output to a monitor or the like by the processing device. The operator of each battery electric propulsion vessel 2 follows the power supply instruction to operate the battery electric propulsion vessel 2 in a form that receives charge from the land power supply apparatus 20 during the course of the action.
On the other hand, when the electric power price of the land power supply facility 20 is higher than the electric power price of the offshore power generation boat 3, the management device 5 generates a power supply command for preferentially receiving electric power supplied from the offshore power generation boat 3 and the offshore power generation boat 3 of the land power supply facility 20 based on the navigation data received from all the battery electric propulsion boats 2, and transmits the generated power supply command to each of the battery electric propulsion boats 2. The power supply command transmitted from the management device 5 is received by the communication device of each battery electric propulsion ship 2, and is output to a monitor or the like by the processing device. The operator of each battery electric propulsion vessel 2 follows the power supply instruction to operate the battery electric propulsion vessel 2 in a form that receives charge from the specially determined offshore power generation vessel 3 during the course of the action. The management device 5 may send an electricity selling instruction to the electric propulsion ship 2 using the battery with surplus power, such as selling surplus power to the land power supply facility 20 after the operation.
At this time, the management device 5 determines an optimal standby position at which each offshore power generation vessel 3 supplies power to all the battery electric propulsion vessels 2 based on the navigation data received from all the battery electric propulsion vessels 2, and transmits the determined standby position to the offshore power generation vessel 3. The standby position transmitted from the management device 5 is received by the communication device of each offshore power generation vessel 3, and is output to a monitor or the like by the processing device. The operator of each offshore power generation vessel 3 moves the offshore power generation vessel 3 to the standby position. When the offshore power generation vessel 3 has surplus power after power is supplied from the offshore power generation vessel 3 to all the battery electric propulsion vessels 2, the management device 5 transmits a power selling instruction such as selling the surplus power to the land power supply facility 20 to the offshore power generation vessel 3.
In the power supply system 1A having the above-described configuration, the battery electric propulsion ship 2 receives power supply from the land power supply facility 20 when the power price of the land power supply facility 20 is lower than the power price of the offshore power generation ship 3, and receives power supply from the offshore power generation ship 3 when the power price of the land power supply facility 20 is higher than the power price of the offshore power generation ship 3, so that the operation cost can be improved.
In the present embodiment, when the electric power price of the land power supply facility 20 is higher than the electric power price of the offshore power generation vessel 3, the offshore power generation vessel 3 is moved to an optimal position for supplying electric power to each battery electric propulsion vessel 2, and therefore, the distance traveled by each battery electric propulsion vessel 2 for charging can be reduced. In addition, the offshore power generation vessel 3 can sell surplus power to the land power supply apparatus 20 after supplying power to the battery electric propulsion vessels 2, and thus the operation cost is improved.
In the present embodiment, when the electric power price of the land power supply facility 20 is higher than the electric power price of the offshore power generation vessel 3, the surplus electric power is supplied to the land power supply facility 20 for the battery electric propulsion vessel 2 having the surplus electric power among the plurality of battery electric propulsion vessels 2, and thus, even when the expected solar power generation amount cannot be obtained due to the night and sunlight conditions in the land power supply facility 20, the necessary electric power can be ensured. The operation cost can be improved.
(modification)
The present invention is not limited to the above-described embodiments, and various modifications are possible within a range not departing from the spirit of the present invention.
For example, the management device 5 may acquire the electric power price data for each predetermined time of the land power supply facility 20, and determine the charging schedule for each battery electric propulsion ship 2 based on the navigation data of all battery electric propulsion ships 2. However, the charging schedule contains a specific determination of the charging moment and the offshore power generation vessel 3 or the onshore power supply facility 20 that should receive the charging. The communication means of the management device 5 send the charging schedule of each battery electric propulsion ship 2 determined by the processing means to the corresponding battery electric propulsion ship 2.
Fig. 4 shows a pattern of a power supply apparatus specifically determined following a charging schedule. For ease of illustration herein, only one battery electric propulsion vessel 2 and one offshore power generation vessel 3 are shown at sea that need to be charged. In fig. 4, the movement path 30 shows a path from the battery electric propulsion vessel 2 to the offshore power generation vessel 3, and the path 31 shows a path from the battery electric propulsion vessel 2 to the land power supply apparatus 20. The movement amounts of the path 30 and the path 31 are equal. Since the charging schedule reflects the electric power price data, the battery electric propulsion ship 2 is herein defined as a power supply device that should receive power supply, in particular, as a power supply device with a lower electric power price (e.g., the offshore power generation ship 3). According to this configuration, each battery electric propulsion ship 2 can be charged at an optimal timing in either the offshore power generation ship 3 or the land power supply facility 20 in accordance with the charging schedule determined based on the navigation data and the electric power price data, and each battery electric propulsion ship 2 can perform an action economically and efficiently.
The management device 5 may execute a ship dispatch plan for all the electric propulsion ships 2 on the basis of the navigation data and the electric power price data received from all the electric propulsion ships 2 every day, determine a navigation schedule including actions to be performed on each electric propulsion ship 2, and transmit the determined navigation schedule to the corresponding electric propulsion ship 2.
Fig. 5 is a graph showing an example of a one-day travel schedule of the battery electric propulsion ship. The vertical axis of fig. 5 represents the power required for each action of the battery electric propulsion ship 2. Fig. 6 is a diagram showing an example of the route 32 following the navigation schedule. Here, for convenience of explanation, the battery electric propulsion boat 2 and the offshore power generation boat 3 are each shown one by one, and the course 32 represents a timetable in the morning. First, as shown in fig. 6, the battery electric propulsion ship 2 goes out (transportation; transit) from one of the ports 12 in the early morning following the travel schedule. The battery electric propulsion boat 2 is then on standby at sea near the entrance of the bay 11. Next, the battery electric propulsion ship 2 sails the large ship 6 that arrives at sea to another port 13. Finally, the battery electric propulsion boat 2 is disposed on the quay wall of the port 13 to tie down the large boat 6 (the boat). The above, the job in the morning ends. After the port 13 is parked for a certain period, the battery electric propulsion ship 2 starts the afternoon operation. The battery electric propulsion ship 2 is charged several times a day due to the limitation of the capacity of the battery, but can receive power from any power supply device in accordance with the power supply price of the offshore power generation ship 3 and the power price of the land power supply device 20 in a time zone after the ports 12 and 13 before and after the departure and the standby medium-level action at sea, following the navigation schedule.
According to this structure, the ship scheduling plan can be automated, and the battery electric propulsion ship 2 can follow the travel schedule decided based on the travel data and the electric power price data, improving the operation cost by traveling.
In the above embodiment, the offshore power generation vessel 3 exclusively supplies the electric power generated by the generator to the battery electric propulsion vessel 2 and the land power supply facility 20, but the offshore power generation vessel 3 may be configured to receive the electric power supply from the land power supply facility 20. For example, the electric power generated by the respective power generation systems 22 to 25 of the land power supply facility 20 may be supplied to the offshore power generation vessel 3, and the battery of the offshore power generation vessel 3 may be charged (see fig. 3).
The management device 5 is configured to be communicable with the offshore power generation vessel 3 and to receive navigation data including movement information of the offshore power generation vessel 3, capacity of a battery of the offshore power generation vessel 3, and remaining battery level.
The management device 5 acquires the power price data for each predetermined time of the land power supply facility 20, and determines one of the generation of power by the offshore power generation vessel 3 and the reception of power from the land power supply facility 20 when the generated power of the offshore power generation vessel 3 is insufficient based on the navigation data and the power price data received from the offshore power generation vessel 3. Specifically, when the power price of the land power supply facility 20 is lower than the power supply price of the offshore power generation vessel 3, the management device 5 generates a command to preferentially receive power supply from the land power supply facility 20, and transmits the generated power supply command to the offshore power generation vessel 3. On the other hand, when the power price of the land power supply facility 20 is higher than the power price of the offshore power generation vessel 3, a command for preferentially receiving power supply in the offshore power generation vessel 3 is generated, and the generated power supply command is transmitted to the offshore power generation vessel 3. In this way, since it is determined whether to supply the electric power generated by the offshore power generation vessel 3 to the battery electric propulsion vessel 2 or to supply the electric power supplied from the land power supply facility 20 to the battery electric propulsion vessel 2, the operation cost can be improved.
In the above embodiment, the offshore power generation vessel 3 generates power using liquefied gas, but may generate power using LPG (Liquefied Petroleum Gas ), biofuel, and hydrogen. In addition, the "offshore power plant" of the present invention may not necessarily be provided with a power generation plant. For example, a pre-charged exchange battery may be mounted on the marine vessel, and when the electric battery propulsion vessel 2 is moored to the marine vessel, the charged battery may be exchanged with the battery of the electric battery propulsion vessel 2. The electric power charged in the battery of the offshore vessel may be supplied to the battery of the battery electric propulsion vessel 2 via a cable.
