Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the flowchart of the virtual power station implementation method for demand side response provided in the embodiment of the present invention is schematic, where the virtual power station implementation method can implement a virtual power station that has a dc load (e.g., a communication device load) and needs to be formed by networking a system using a backup power supply, such as a communication base station (e.g., a 5G communication base station, a 4G communication base station), a server station, and the like. The method of the embodiment can be implemented in a platform server accessed to a virtual private network, and the virtual private network includes a base station power supply system of all communication base stations in the same power dispatching area. For each communication base station, the base station power supply system comprises a main controller, a UPS power module, a storage battery pack and a monitoring module, and the communication equipment load in the communication base station is supplied with power through the UPS power module and the storage battery pack. Each main controller is provided with a unique fixed IP address, the base station power supply system is accessed to the virtual private network through the main controller, and the VPN server in the virtual private network maintains the virtual private network and transmits instruction data and state data through the fixed IP addresses.
Specifically, the method of this embodiment may be specifically executed by a platform server, and includes the following steps:
step S11: the platform server receives battery status data from each base station power supply system that is accessed to the virtual private network.
The battery state data can be collected by a monitoring module in the base station power supply system and include ampere-hour capacity of each single battery in a local storage battery pack (namely, a storage battery pack in the same base station power supply system). Of course, in practical applications, the battery status data may also include other data of each battery pack, such as voltage, discharge current, internal resistance, and the like. In the power supply system of the base station, the monitoring module can be connected to a storage battery loop and is in signal connection with the main controller through a serial port and the like.
Step S12: during the peak time of the power load, the platform server sends a first instruction to the main controller of the base station power supply system meeting a first preset condition, and the main controller receiving the first instruction can execute the first instruction and control the local UPS power module (i.e., the UPS power module located in the same base station power supply system as the main controller) to output a first voltage, where the first voltage is less than or equal to the nominal voltage of the local storage battery (i.e., the storage battery located in the same base station power supply system as the main controller), for example, when the nominal voltage of the storage battery is 48V, the first voltage may be 48V. At the moment, in the base station power supply system, the storage battery pack supplies power to the communication equipment load, so that the communication base station does not need external power supply, and the load of a power grid is reduced. The power supply peak period is a load peak period of power in an area where the communication base station is located.
And during the peak time of the power load, the platform server further sends a second instruction to the main controllers of all the base station power supply systems meeting a second preset condition, and the main controller receiving the second instruction can execute the second instruction and control the local UPS power module to output a second voltage, where the second voltage is greater than the nominal voltage of the local storage battery pack and less than the charging voltage of the local storage battery pack, and for example, when the nominal voltage of the storage battery pack is 48V and the charging voltage is 55V, the second voltage is 53.5V. At this time, in the base station power supply system, the UPS power module supplies power to the communication equipment load, and the storage battery pack is in an unfilled state.
By setting the second preset condition, the storage battery pack with relatively poor performance can be protected, meanwhile, the corresponding communication base station can be ensured to continuously operate in the state of power grid outage, and the phenomenon that the communication base station is disconnected due to the fact that the storage battery pack cannot provide enough electric energy is avoided.
Step S13: in the power load valley period, the platform server sends a third instruction to the main controllers of all the base station power supply systems meeting a third preset condition, and the main controllers receiving the third instruction can execute the third instruction and control the local UPS power module to output a third voltage, where the third voltage is greater than the charging voltage of the local storage battery pack, for example, when the nominal voltage of the storage battery pack is 48V and the charging voltage is 55V, the third voltage is 56.5V. At the moment, in the power supply system of the base station, the UPS module supplies power to the communication equipment load, and meanwhile, the UPS module also charges the storage battery pack, so that redundant electric energy of a power grid is consumed.
In the power load off-peak period, the platform server also sends a second instruction to the main controllers of all base station power supply systems which do not conform to the third preset condition, so that the UPS power supply module supplies power to the communication equipment load in the corresponding base station power supply system, and the storage battery pack is in an unfilled state.
In the virtual power station implementation of demand-side response, the steps S12 and S13 may be executed alternately or at intervals according to the peak time and the valley time of the power load, and the step S11 may be executed synchronously during the execution of the steps S11 and S12. The virtual power station implementation method utilizes the virtual private network to communicate with base station power supply systems of all communication base stations in the same region, and utilizes the reserve storage battery energy of the communication base stations to supply power to communication loads at peak time of regional power loads, thereby reducing or not using electric energy of a power grid and realizing the effect of reducing load of the power grid. And because the corresponding instruction is generated by the platform server, the operation is only needed on the platform server when the control strategy is adjusted, and the operation on the base station power supply system of each communication base station is not needed, so that the system maintenance process is greatly simplified.
In one embodiment of the present invention, to further balance the influence of the communication base stations on the grid load, the peak time of the power load may be divided into M preset time periods, and meanwhile, the communication base stations meeting the first preset condition are divided into M groups, where M is an integer greater than or equal to 2. Accordingly, in step S12, when the platform server sends the first instruction to the master controllers of all the base station power supply systems meeting the first preset condition, the platform server may send the first instruction to the M groups of the master controllers of the base station power supply systems meeting the first preset condition in sequence in M preset time periods, and send the first instruction only to one group of the master controllers of the base station power supply systems meeting the first preset condition in each preset time period, so as to discharge the storage battery packs of the base station power supply systems in the virtual private network in batches.
Specifically, M may determine the durations of the M preset periods according to the duration of the peak period of the power load and the duration of the discharging of the storage battery pack in the communication base station from the full-power state to the preset depth of discharge. For example, when the duration of the peak period of the power load is 3 hours, and the duration of the discharge of the storage battery pack in the communication base station from the full state to the preset discharge depth is 1.5 hours, M may be 2. When 100 communication base stations are included in the virtual private network, the battery pack of 50 communication base stations can be discharged by the first instruction in the first 1.5 hours of the power load peak period; and at the last 1.5 hours of the peak period of the power load, the battery packs in the other 50 communication base stations are discharged by the first instruction.
Of course, in practical applications, the value of M and the number of base station power supply systems receiving the first instruction in each group may be determined according to the number of base station power supply systems in the virtual private network.
Similarly, the power load valley period may be divided into M preset periods, and correspondingly, in step S13, when the platform server sends the third instruction to the main controllers of all the base station power supply systems meeting the third preset condition, the platform server may also send the third instruction to the main controllers of M groups of base station power supply systems meeting the third preset condition in sequence in the M preset periods, and send the third instruction only to the main controllers of one group of base station power supply systems meeting the third preset condition in each preset period, so that the storage battery packs of the base station power supply systems in the virtual private network are charged in batches, and the communication base stations are prevented from being charged at the same time to cause impact on the power grid.
In one embodiment of the present invention, as illustrated in connection with fig. 2, the electrical load peak periods and the electrical load valley periods may be generated by:
step S15: calculating the mean power according to a power load curve issued by power grid dispatching, wherein the power load curve is received from an external power management system;
step S16: and taking a time period in the power load curve larger than the average power as a power load peak time period, and taking a time period in the power load curve smaller than or equal to the average power as a power load valley time period.
In the power grid power utilization scheduling management, a power department sends a power load response curve of a certain area to a power utilization unit in advance through a power management system, so that the power utilization unit is encouraged to close part of the power loads in the peak period of the power loads, namely the power loads are disengaged hard, economic compensation is given, and the power utilization unit is encouraged to use more power in the low peak period of the power loads, so that the load is contributed to a power grid, and the power grid electric energy is absorbed. According to the embodiment, the peak time and the valley time of the power load are automatically calculated and generated directly according to the power load curve from the power department, so that the automatic adjustment of the peak time and the valley time of the power load can be realized, the power load of a power distribution network can be better matched, and meanwhile, the manual operation is reduced.
In another embodiment of the present invention, in step S12, the first instruction is sent to the main controller of all base station power supply systems meeting the first preset condition, the number of communication base stations receiving the first instruction and performing demand-side response may also be adjusted according to the change of the power load curve, and the information of the number of communication base stations performing demand-side response and the total power sum is sent to the power scheduling system, so that the power scheduling system is facilitated to allocate power. That is, the durations of the M preset time periods may be different, and the number of the base station power supply systems (meeting the first preset condition) that each group receives the first command at the same time may be different. For example, the time when the electrical load exceeds the average power by less than 20%, and the time when the electrical load exceeds the average power by more than 20% may be respectively used as two preset time periods, and accordingly, the number of the base station power supply systems receiving the first instruction is larger in the preset time period corresponding to the time when the electrical load exceeds the average power by 20%. For example, when the virtual private network includes 100 communication base stations, a first instruction is sent to a base station power supply system of 70 communication base stations in a preset time period corresponding to the power load exceeding the average power by 20%; and sending a first instruction to the base station power supply systems of the other 30 communication base stations in a preset time period corresponding to the power utilization load not exceeding 20% of the average power, so as to balance the power grid load.
In an embodiment of the present invention, the method for implementing a demand-side responsive virtual power station includes, in addition to steps S11-S13: and establishing the reference ampere-hour capacity of each base station power supply system according to the battery state data received from each base station power supply system, wherein the reference ampere-hour capacity of the base station power supply system is the minimum value of the ampere-hour capacity in the single battery of the storage battery pack of the base station power supply system. This step may be performed at full battery pack conditions for all base station power supply systems, for example at the end of each power load valley period.
Accordingly, the first preset condition in step S12 includes: the real-time ampere-hour capacity of a storage battery pack of the base station power supply system is 0.8 times larger than the reference ampere-hour capacity. The second preset condition includes: the real-time ampere-hour capacity of the storage battery pack of the base station power supply system is less than or equal to 80% of the reference ampere-hour capacity, or the storage battery pack of the base station power supply system discharges to reach a preset discharge depth (for example, 60%).
The third preset condition in step S13 includes: the real-time ampere-hour capacity of a storage battery pack of the base station power supply system is smaller than the reference ampere-hour capacity.
For regions where peak to valley electricity prices are present, the method further comprises: and establishing the reference ampere-hour capacity of each base station power supply system according to the battery state data received from each base station power supply system, wherein the reference ampere-hour capacity of the base station power supply system is the minimum value of the ampere-hour capacity in the single battery.

The third preset condition in step S13 includes: the current time is at the valley price time and the real-time ampere-hour capacity of a storage battery pack of the base station power supply system is smaller than the reference ampere-hour capacity.
In addition, as a further improvement of the present invention, the method of the present invention further comprises:
recording the discharge duration t of each base station power supply system in a preset perioddAnd a time period t of chargingcThe base station power supply system discharges when the local UPS power module outputs a first voltage (namely, the storage battery pack discharges), and charges when the local UPS power module outputs a third voltage (namely, the storage battery pack charges);
