It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
Example one
Fig. 1 is a flowchart of a load scheduling method for an energy storage device according to an embodiment of the present invention, where this embodiment is applicable to a situation of performing load scheduling on the energy storage device, and the method may be executed by a load scheduling apparatus for an energy storage device according to an embodiment of the present invention, where the apparatus may be integrated in a scheduling device and implemented in a software and/or hardware manner, as shown in fig. 1, the method specifically includes the following steps:
and S110, acquiring load dispatching requirements of the power grid and dispatching application information sent by the registered energy storage equipment.
The power grid load scheduling demand refers to the amount of demand for power load in the current power grid, and can be determined according to the sum of the generated energy of all power supply sources in the current power grid and the predicted power consumption of all electric equipment. The energy storage device is a device with an electric energy storage function, and can comprise electric vehicles such as electric automobiles, electric ships or electric bicycles containing storage batteries; the registered energy storage device refers to an energy storage device which completes registration at the dispatching device. Energy storage equipment such as electric vehicles and the like are used as distributed energy storage equipment in a power grid, so that the energy storage equipment is free from being constrained by natural conditions, and the output power is stable and has small random fluctuation.
Specifically, the scheduling device monitors load changes of the power grid in real time, acquires load scheduling requirements of the current power grid according to a preset frequency, and receives scheduling application information actively sent by registered energy storage devices included in the scheduling device.
Illustratively, the scheduling application information may include: the charging application information refers to information that the registration equipment applies for charging from the power grid, and the discharging application information refers to information that the registration equipment applies for discharging to the power grid. Alternatively, the scheduling application information may include: the remaining capacity, the battery capacity, and the planned usage capacity of the energy storage device are registered.
And S120, determining a scheduling instruction corresponding to the registered energy storage device according to the load scheduling requirement and the scheduling application information.
The scheduling instruction corresponding to the registered energy storage device refers to a scheduling instruction fed back by the scheduling device according to the scheduling application information of the registered energy storage device and the power grid load scheduling requirement, and the scheduling instruction may include: indicating charging, indicating discharging, or not receiving a scheduling application.
In a specific example, if the scheduling application information of the registered energy storage device may be charging application information or discharging application information, the scheduling device may determine the scheduling instruction according to the scheduling application information and the load scheduling requirement. For example, if the scheduling application information of the registered energy storage device is the charging application information and the load scheduling requirement is smaller than a preset rated load threshold, determining that the scheduling instruction indicates charging; and when the load scheduling requirement is greater than the preset quota load threshold, not receiving the scheduling application. If the scheduling application information of the registered energy storage equipment is discharging application information and the load scheduling requirement is smaller than a preset rated load threshold, determining that a scheduling instruction indicates discharging; and when the load scheduling requirement is greater than the preset quota load threshold, not receiving the scheduling application.
In another specific example, if the scheduling application information of the registered energy storage device may include: and if the residual electric quantity, the battery capacity and the planned use electric quantity of the registered energy storage equipment are registered, the scheduling equipment can pre-judge the scheduling requirement of the registered energy storage equipment according to the scheduling application information, and determine a scheduling instruction corresponding to the registered energy storage equipment according to the pre-judged scheduling requirement of the registered energy storage equipment and the load scheduling requirement of the power grid. For example, the scheduling requirement of the registered energy storage device is judged in advance to be charging according to the scheduling application information, and when the load scheduling requirement is smaller than a preset rated load threshold, the scheduling instruction is determined to indicate charging, and the charging amount can be determined according to the scheduling application information of the registered energy storage device and the load scheduling requirement; and when the load scheduling requirement is greater than the preset quota load threshold, not receiving the scheduling application. The method comprises the steps that the scheduling requirement of the registered energy storage equipment is judged in advance to be discharging according to scheduling application information, when the load scheduling requirement is smaller than a preset rated load threshold value, a scheduling instruction is determined to indicate discharging, and the discharging amount can be determined according to the scheduling application information and the load scheduling requirement of the registered energy storage equipment; and when the load scheduling requirement is greater than the preset quota load threshold, not receiving the scheduling application.
And S130, sending the scheduling instruction to the registered energy storage device, so that the energy storage device completes load scheduling according to the instruction of the scheduling instruction.
After the scheduling equipment determines the scheduling instruction of the registered energy storage equipment, the scheduling instruction is sent to the registered energy storage equipment applying for scheduling, so that the energy storage equipment completes load scheduling according to the instruction of the scheduling instruction.
For example, if the registered energy storage device receives a scheduling instruction sent by the scheduling device to instruct charging, the charging is performed according to the instruction of the charging instruction. And if the registered energy storage equipment receives a scheduling instruction sent by the scheduling equipment to indicate discharging, discharging according to the instruction of the discharging instruction. And if the registered energy storage equipment receives the scheduling instruction sent by the scheduling equipment, the registered energy storage equipment does not receive the scheduling application information.
It should be noted that, if the scheduling application information sent by the registered energy storage device is not received, the registered energy storage device is recorded in the alternative list of the scheduling device, and when the scheduling application information sent by the registered energy storage device matches the load scheduling requirement of the scheduling device, a scheduling instruction for receiving the application is sent to the registered energy storage device. For example, the registered energy storage device applies for discharging, but the load scheduling requirement of the current power grid is smaller, and the registered energy storage device is not required to discharge, so that the registered energy storage device can be recorded in the alternative list of the scheduling device, and when the load scheduling requirement of the current power grid is smaller than the set load threshold, the registered energy storage device in the alternative list is preferentially discharged.
According to the technical scheme, the load scheduling requirement of the power grid and the scheduling application information sent by the registered energy storage device are obtained, the scheduling instruction corresponding to the registered energy storage device is determined according to the load scheduling requirement and the scheduling application information, the scheduling instruction is sent to the registered energy storage device, so that the energy storage device completes load scheduling according to the scheduling instruction, the energy storage devices such as electric vehicles and the like can be used as distributed energy storage devices in the power grid, the constraint of natural conditions is avoided, the output power is stable, the random fluctuation is small, scheduling is performed according to the load scheduling requirement change in the power grid, on the premise that the use of users is not influenced, centralized scheduling of the load of the power grid can be flexibly participated, potential energy storage devices in the power grid are fully scheduled and used, and therefore the safety and the stability of the power grid are improved.
Optionally, the scheduling application information initiated by the registered energy storage device includes: the determining, according to the load scheduling requirement and the scheduling application information, a scheduling instruction corresponding to the registered energy storage device includes:
determining the difference value between the planned use capacity and the residual capacity of the registered energy storage equipment as the schedulable capacity of the registered energy storage equipment;
if the schedulable electric quantity is a negative value and the load scheduling requirement is greater than a preset load threshold value, determining that the electric quantity of the registered energy storage equipment is charged to be the planned using electric quantity by the scheduling instruction of the registered energy storage equipment;
if the schedulable electric quantity is a negative value and the load scheduling requirement is smaller than a preset load threshold value, determining that the electric quantity charged to the registered energy storage equipment by the scheduling instruction of the registered energy storage equipment is the battery capacity;
if the schedulable electric quantity is a positive value and the load scheduling requirement is greater than a preset load threshold value, determining that the scheduling instruction of the registered energy storage equipment indicates discharging, and discharging until the discharging quantity of the registered energy storage equipment is the planned use electric quantity;
and if the schedulable electric quantity is a positive value and the load scheduling requirement is smaller than a preset load threshold value, determining that the scheduling instruction of the registered energy storage equipment indicates not to receive the scheduling application.
Specifically, the schedulable electric quantity of the registered energy storage device is determined according to the residual electric quantity and the planned used electric quantity of the registered energy storage device contained in the scheduling application information initiated by the registered energy storage device, and the scheduling application requirement of the registered energy storage device is determined according to the schedulable electric quantity. If the schedulable electric quantity is a negative value, the schedulable electric quantity indicates that the scheduling application requirement is for applying charging, and if the schedulable electric quantity is a negative value, the schedulable electric quantity indicates that the scheduling application requirement is for applying discharging. And further determining a scheduling instruction according to the scheduling application requirement of the registered energy storage equipment and the load scheduling requirement of the power grid to indicate the registered energy storage equipment to charge, discharge or wait for scheduling, and determining the charging amount or the discharging amount according to the battery capacity and the planned using electric quantity of the registered energy storage equipment.
For example, when the schedulable electric quantity is a negative value, it means that the scheduling application requirement is for applying charging, and if the load scheduling requirement is greater than the preset load threshold, it is determined that the scheduling instruction of the registered energy storage device indicates that the electric quantity of the registered energy storage device is the planned use electric quantity; if the load scheduling requirement is smaller than a preset load threshold, determining that the scheduling instruction of the registered energy storage equipment indicates that the electric quantity charged to the registered energy storage equipment is the battery capacity; when the schedulable electric quantity is a positive value, the schedulable electric quantity indicates that the scheduling application requirement is application discharge, if the load scheduling requirement is greater than a preset load threshold value, the scheduling instruction of the registered energy storage equipment indicates discharge, and the discharge quantity of the registered energy storage equipment is the planned use electric quantity after discharge; and if the load scheduling requirement is smaller than the preset load threshold, determining that the scheduling instruction of the registered energy storage equipment indicates not to receive the scheduling application, so that the registered energy storage equipment waits for scheduling.
