As shown in fig. 1, a preferred embodiment of the present invention provides a charging regulation and control method for performing charging regulation and control on a charging device newly connected to a power grid, where the charging regulation and control method includes the following steps:
step S210: and receiving the charging requirement of the charge-simulated equipment and recording the charging access time.
In the embodiment, in the community, in order to facilitate charging of residents, the charging equipment is arranged near the community parking space so that a user can conveniently use the charging equipment to supply power after parking a vehicle into the parking space. Further, in this embodiment, all the charging devices in the community are connected to a charging regulation and control system to receive a regulation and control instruction of the charging regulation and control system to perform charging regulation and control. Further, in this embodiment, the charging regulation and control system is configured to regulate and control charging of a charging device on a phase line in a power grid, where the charging device on the phase line is a pseudo-charging device every time the charging device is newly connected to a charging vehicle, and the charging regulation and control system can regulate and control charging of the pseudo-charging device according to an electrical load condition of the power grid to ensure that the pseudo-charging device supplies power to the vehicle newly connected to the power grid.
Furthermore, when a user needs to supply power to a vehicle, the charging simulation equipment can be connected with the vehicle, and then the charging simulation equipment is started in a code scanning or card swiping mode. It can be understood that after the user starts the charge simulation equipment, the charge requirement of the charge simulation equipment can be obtained. Further, when the charging requirement of the charge-simulated device is acquired, the time of receiving the charging requirement is recorded at the same time, and the time is used as the charging access time of the charge-simulated device. It can be understood that the charging access time is the time for acquiring the charging demand of the device to be charged.
Step S220: and receiving the available charging power information to perform charging regulation and control on the charging equipment in the charging process, and recording the charging regulation and control time.
Further, in this embodiment, the power control system of the community periodically queries the power consumption power of the residential power line and the power consumption power of the charging line in the community, calculates the available charging power of the phase line according to the power grid capacity, the power consumption power of the residential power line and the power consumption power of the charging line, and periodically adjusts and controls charging of the charging device during charging in the phase line according to the available charging power. In this embodiment, the available charging power information includes a value of the available charging power, the value of the available charging power is a difference between the power grid capacity and the total power consumption, and the total power consumption is a sum of the power consumption of the residential electric line and the power consumption of the charging line. It is understood that, for example: the charging regulation and control period of the community power control system is 1 hour, namely the community power control system inquires the power consumption power of the residential electric line and the power consumption power of the charging line every 1 hour and calculates the available charging power, and as the power consumption power of the residential electric line is in a changed state according to different residential power consumption conditions, the available charging power calculated by the community power regulation and control system during each charging regulation and control is different, and the numerical value of the available charging power is possibly greater than or less than the sum of the current charging powers of all charging devices in the phase line, so that the charging power of the charging devices in the charging process can be regulated and reduced or increased according to the available charging power information in the regulation and control process. And after receiving the available charging power information, the charging equipment in charging regulates and controls the charging power of the charging equipment in charging according to the available charging power information.
Further, in this embodiment, after receiving the available charging power information, the distribution scheme of the available charging power is calculated, the target charging power information of the charging device during charging is calculated according to the distribution scheme obtained by calculation, and the target charging power is issued to the charging device during charging in the phase line, so as to perform charging regulation. It can be understood that the target charging power information includes a value of a target charging power, where the target charging power is a charging power that the charging device in charging intends to achieve, that is, after the charging regulation and control process is finished, the charging power of the charging device in charging is the target charging power. For example, the charging power of the charging device during charging is 5KW, the target charging power is 10KW, and then the charging device during charging needs to adjust the charging power from 5KW to 10 KW. Further, the time of sending the target charging power is recorded as the charging regulation time. In this embodiment, after receiving the target charging power information, the charging device during charging adjusts the current charging power to the sent target charging power within a preset time, so as to implement charging regulation. It is understood that the charging device is used for charging a vehicle, and due to the characteristics of the vehicle battery, when the charging power of the charging device is adjusted to be high or low, the charging power acceptable to the vehicle battery needs a certain time to be adjusted to the target power, so that the charging device in the charging process needs a preset time to be adjusted to the target power. Further, when the time after the start of the charging regulation does not exceed the preset time, the charging power is being regulated and controlled and is in the process of changing, so that the load in the phase line is unstable; when the time after the start of the charging regulation exceeds the preset time, the charging power is regulated to be in a relatively stable state, so that the load in the phase line is stable. Further, after receiving the target charging power, the charging device under charge needs to communicate with a connected vehicle to determine whether the vehicle can bear the target charging power, so that when the vehicle cannot bear the target charging power, the charging power cannot be applied to the charging device under charge, and therefore, the charging device becomes idle charging power in the phase line.
Step S230: and acquiring the last charging regulation and control time and comparing the charging access time with the last charging regulation and control time to obtain a comparison result.
Further, after receiving the charging access time, the last charging regulation and control time can be inquired, and the charging access time is compared with the last charging regulation and control time to obtain a comparison result. Further, in this embodiment, the last charge regulation time is a time of one charge regulation having a minimum difference from the charge access time. For example: the recorded charging control time is 08:50, 09:10 and 09:30, and the charging access time is 09:31, then the last charging control time obtained by the comparing unit 20 is 09: 30. Further, in this embodiment, the comparison result includes that a difference between the charging access time and the last charging regulation and control time is not less than a preset time, or that a difference between the charging access time and the last charging regulation and control time is less than the preset time. Further, if the comparison result is that the difference between the charging access time and the last charging regulation and control time is not less than the preset time, it indicates that the phase line is not in the charging regulation and control process at this time, i.e., the load is in a stable state; and if the comparison result is that the difference value between the charging access time and the last charging regulation and control time is less than the preset time, the phase line is in the charging regulation and control process at the moment, namely the load is in an unstable state. It can be understood that, since the charging device needs a preset time to adjust to the target charging power after receiving the charging power distribution scheme, the charging power of the charging device in the phase line, that is, the charging load, is in the process of continuously increasing or decreasing within the preset time, and at this time, the charging power of the charging device is in a continuously changing state. If the difference value between the charging access time and the last charging regulation and control time is not less than the preset time, it is indicated that the charging power of the charging equipment in the phase line is in a relatively unchanged state when the charge-simulated equipment is accessed, that is, the load is stable; if the difference value between the charging access time and the last charging regulation and control time is smaller than the preset time, it indicates that the charging power of the charging equipment in the phase line is still in a continuously changing state when the charge-simulated equipment is accessed, i.e. the load is unstable.
Step S240: and controlling a first power supply unit or a second power supply unit to supply power to the charge simulating equipment according to the comparison result.
Further, in this embodiment, when performing the charging regulation, the operating state of the switch unit needs to be controlled according to the comparison result, so as to control the first power supply unit or the second power supply unit to supply power. Further, in this embodiment, the switch unit includes a first operating state, a second operating state, and a third operating state, and the switch unit is capable of operating in the first operating state, the second operating state, or the third operating state to switch power supply of the first power supply unit or the second power supply unit.
Further, when the comparison result is that the difference value between the charging access time and the last charging regulation and control time is not less than the preset time, it is indicated that the current load is stable, and the charging regulation and control can be performed, at this time, the idle charging power in the phase line needs to be inquired, and the newly accessed quasi-charging device needs to be charged and controlled according to the idle charging power in the phase line. Specifically, the current charging power of the charging device in phase line charging needs to be queried before querying the idle power, the current charging powers are added, and then the sum of the current charging powers of the charging devices in charging is subtracted from the current available charging power of the phase line to obtain the idle charging power, that is, the idle charging power is the difference between the available charging power and the total power of the charging devices in charging, and the total power of the charging devices in charging is the sum of the charging powers of all the charging devices in charging. For example: charging equipment in the phase line is battery charging outfit A and B, and battery charging outfit A's current charging power is 10KW, and battery charging outfit B's current charging power is 5KW, the current available charging power information of phase line is 30KW, then idle charging power is 30KW- (10KW +5KW) ═ 15 KW.
Further, after receiving the idle charging power, further inquiring the starting charging power and the limited charging power of the device to be charged, so as to compare the relation between the idle charging power and the starting charging power and the limited charging power, and further determine the charging power of the device to be charged. Further, in this embodiment, the start charging power is the minimum power required to start the charging function of the charging device, and the limit charging power is the smaller one of the maximum charging power of the charging device and the maximum charging power of the vehicle to which the charging device is connected. For example: the maximum charging power of the charge simulating equipment is 20KW, the maximum charging power of a vehicle connected with the charge simulating equipment is 15KW, and the limited charging power of the charge simulating equipment is 15 KW.
Further, when the comparison result is that the difference value between the charging access time and the last charging regulation and control time is smaller than the preset time, the switch unit is switched to the first working state; when the comparison result is that the difference value between the charging access time and the last charging regulation and control time is not less than the preset time and the idle charging power is less than the starting charging power of the charge simulating equipment, controlling the switch to be switched to the first working state; when the comparison result is that the difference value between the charging access time and the last charging regulation and control time is not less than the preset time, and the idle charging power is not less than the starting charging power of the charge-simulated equipment and not more than the limited charging power of the charge-simulated equipment, the switch is switched to the second working state; and when the comparison result is that the difference value between the charging access time and the last charging regulation and control time is not less than the preset time and the idle charging power is greater than the limited charging power of the charge-simulated equipment, the switch unit is switched to the third working state.
Further, when the comparison result shows that the difference between the charging access time and the last charging regulation and control time is smaller than the preset time, it indicates that the charging device in the phase line is in a charging regulation and control state, and the idle charging power of the phase line cannot be accurately calculated, and at this time, the switch unit is switched to a first working state, so that the quasi-charging device is connected with the second power supply unit, and the second power supply unit supplies power to the quasi-charging device. Further, the second power supply unit is only used for temporarily starting the charging function of the device to be charged when the power of the power grid is insufficient, so that the second power supply unit supplies power to the device to be charged by using the starting charging power under the condition, and the charging power of the device to be charged is adjusted when the control unit performs charging regulation next time.
Further, when the comparison result is that the difference between the charging access time and the last charging regulation and control time is not less than the preset time and the idle charging power is less than the starting charging power of the quasi-charging device, it indicates that the current idle charging power of the phase line is insufficient to start the charging function of the quasi-charging device, and at this time, the quasi-charging device cannot be powered through the power grid, that is, the quasi-charging device cannot be powered through the first power supply unit. At this time, the switch unit is switched to a first working state, so that the to-be-charged device is connected with the second power supply unit, and the second power supply unit supplies power to the to-be-charged device. Further, the second power supply unit is only used for temporarily starting the charging function of the device to be charged when the power of the power grid is insufficient, so that the second power supply unit only needs to ensure that the charging of the device to be charged can be started, and at the moment, the control unit controls the second power supply unit to supply power to the device to be charged by starting charging power.
Further, when the comparison result is that the difference between the charging access time and the last charging regulation and control time is not less than the preset time and the idle charging power is not less than the starting charging power of the quasi-charging device and not greater than the limited charging power of the quasi-charging device, it is indicated that the current charging power of the phase line is sufficient to start the charging function of the quasi-charging device, and at this time, the quasi-charging device can be supplied with power through the power grid, that is, the quasi-charging device can be supplied with power through the first power supply unit. At this time, the switch unit is switched to a second working state, so that the to-be-charged device is connected with the first power supply unit, and the first power supply unit supplies power to the to-be-charged device. Further, since the charging power of the charging device in the phase line is already relatively stable, at this time, the idle charging power may be completely transmitted to the pseudo-charging device to start charging of the pseudo-charging device, and at this time, the first power supply unit 30 is controlled to supply power to the pseudo-charging device with the idle charging power.
Further, when the comparison result indicates that the difference between the charging access time and the last charging regulation and control time is not less than the preset time and the idle charging power is greater than the limited charging power of the device to be charged, it indicates that the current idle charging power is sufficient to start the charging function of the device to be charged and exceeds the bearing range of the device to be charged, and at this time, the switch unit is switched to a third working state, so that the first power supply unit is connected with the device to be charged and the second power supply unit, and the first power supply unit supplies power to the device to be charged and the second power supply unit. It can be understood that, since the second power supply unit stores the backup power, after the second power supply unit supplies power to the device to be charged, the electric quantity of the second power supply unit gradually decreases, and at this time, the electric quantity of the second power supply unit can be recovered by charging the second power supply unit through the first power supply unit, so as to charge the device to be charged when the idle charging power is insufficient. At this time, the device to be charged is controlled to supply power with the first charging power, and the second power supply unit is controlled to supply power with the second charging power. Further, in this embodiment, the first charging power is equal to a limit charging power of the device to be charged, and the second charging power is equal to a difference between the idle charging power and the first charging power.
