Claims (3)

  1. Equipped with a processor, The aforementioned processor, It communicates with the battery, which is a distributed resource used by the consumer. Remote control is performed by selecting one of the multiple operating states of the distributed resource. Based on the supply of adjustment capacity orders issued to adjust the supply and demand of electricity, the power grid balances supply and demand, After the supply and demand balance of the power system has been adjusted by remote control, an anomaly related to remote control is detected based on information obtained from the distributed resources , which indicates that the distributed resources are continuing to operate in the specified operating state. A remote control device that performs processing to enable remote control or transmits instructions for remote control in response to the detection of an anomaly.
  2. The remote control device according to claim 1, characterized in that the detection is detected as an abnormality related to the remote control when the amount of charge stored in the storage battery is less than the emergency charge amount that should be stored in order to use the storage battery in an emergency.
  3. The aforementioned processor, Information is obtained indicating whether or not the area where the aforementioned battery is installed is experiencing a power outage. The aforementioned detection occurs when the amount of charge stored in the battery becomes less than the emergency charge amount. Furthermore, the remote control device according to claim 2, characterized in that it detects an abnormality related to the remote control when the area is not experiencing a power outage.

Description

This invention relates to a remote control device. Patent Document 1 describes an energy storage system characterized by comprising a battery and a control unit that controls the operation of the battery in accordance with a pre-planned discharge command for the battery included in the commands to the battery from the aggregator. Japanese Patent Publication No. 2018-57071 This figure shows an example of the overall configuration of a control system to which this embodiment is applied.This figure shows an example of the hardware configuration of the management server.This figure shows an example of the functional configuration of the management server.This flowchart shows an example of the processing flow of the management server.This flowchart shows an example of the processing flow of the communication interruption detection unit.This flowchart shows an example of the processing flow of the operation lock-up detection unit.This flowchart shows an example of the processing flow of the discharge abnormality detection unit. Embodiments of the present invention will be described in detail below with reference to the attached drawings. <Overall configuration of the remote control system> Figure 1 shows an example of the overall configuration of the remote control system 1 to which this embodiment is applied. The remote control system 1 according to this embodiment includes a management server 10, a storage battery 20, and a HEMS (Home Energy Management System) 30. The management server 10 is a server device installed in an aggregator that adjusts the balance of electricity supply and demand. The aggregator adjusts the balance of electricity supply and demand based on, for example, adjustment power supply orders issued by power companies, etc. An adjustment power supply order is an order issued to adjust the demand and supply of electricity. More specifically, it is an order that requests a reduction in electricity demand or an order that requests an increase in electricity demand. Based on the adjustment power supply order it has acquired, the management server 10 remotely controls the storage battery 20, which is a distributed resource installed at a customer facility and used by the customer, to supply power adjustment power. A customer facility is one example of a residence, but it may also be a business or factory that consumes electricity. Communication between the management server 10 and the battery 20 occurs via the HEMS 30. The HEMS 30 is a residential equipment control device that controls energy such as electricity used in a house. The HEMS 30 is connected to the battery 20 via network 80. Furthermore, the HEMS 30 is connected to the management server 10 via network 90. Networks 80 and 90 are information communication networks responsible for communication between each device. The type of network 80 and 90 is not particularly limited as long as it is capable of transmitting and receiving data; for example, it could be the Internet, a Wide Area Network (WA), etc. The communication lines used for data communication may be wired or wireless, or a combination of both. Furthermore, the system may be configured to connect each system via multiple networks and communication lines. Note that the management server 10 and the battery 20 may communicate without going through the HEMS 30. The storage battery 20 only needs to be capable of charging and discharging electricity, and the type of battery is not particularly limited. Examples of storage batteries 20 include lithium-ion batteries and nickel-metal hydride batteries. The storage battery 20 can be charged with electricity supplied from the power grid, electricity supplied from solar panels installed at customer facilities, or electricity supplied from other power supply equipment. Furthermore, the storage battery 20 may, for example, be the battery of an electric vehicle (EV) equipped with an on-board charging device. The storage battery 20 includes a battery control unit 21 that controls the storage battery 20. The battery control unit 21 performs a process to change the operating mode based on the operating mode instruction obtained from the HEMS 30. In this embodiment, the storage battery 20 has three operating modes. The battery control unit 21 executes one of these three operating modes. The operating modes are a charging mode as the first operating mode, a discharging mode as the second operating mode, and a standby mode as the third operating mode. In charging mode, the battery 20 is charged by receiving power from the power grid or power supply equipment such as solar panels. In discharge mode, the power stored in the battery 20 is discharged. In discharge mode, power is either discharged to the power grid or consumed internally. In standby mode, the device remains idle without charging or discharging. Furthermore, the battery control unit 21 measures the charge level of the storage battery 20 and transmits the measured charge level to the HEMS 30
