Detailed Description
The present application is described in further detail below with reference to figures 1-2.
The embodiment of the application discloses a comprehensive energy allocation method for a college building group based on multi-energy complementation, the method is based on a college energy control system, colleges and universities are provided with different auxiliary power supply modes including solar power generation or wind power generation and the like according to functional partitions, and generated electric quantity is stored in a preset storage battery after the auxiliary power supply is finished; conventionally, electric facilities in schools are directly supplied with power through a power grid, and in special cases, auxiliary power supply equipment can be started to supply power to the electric facilities in schools.
As shown in fig. 1, the method comprises the steps of:
and S10, acquiring corresponding real-time output power in different areas in real time.
Wherein, divide into the school according to the service function and teach district, dormitory district, activity district etc. and every district corresponds the battery equipment that is fit for having carried out the charge-discharge with the auxiliary energy of electric wire netting power supply and difference.
And S11, calculating and generating the high-correction output power according to the real-time output power.
The method comprises the steps of counting the times of real-time output power acquired within preset time, setting the real-time output power with the largest occurrence times as actual output power in a preset area, respectively acquiring actual output power corresponding to different areas, calculating the sum of the actual output power in the different areas, and setting the sum as college output power.
S12, judging whether the high-correction output power is in the preset critical output range.

And S14, if not, starting the auxiliary energy source to perform power supply operation.
And starting the storage battery corresponding to the auxiliary power supply equipment, starting the related storage battery to supply power to the corresponding electric equipment, and simultaneously, continuously charging the electric equipment without the auxiliary equipment by the power grid until the circuit output information is positioned in the preset critical output range again. For example, if the preset critical output range is a-B and a is smaller than B, the circuit output information is C, and C is larger than B, the auxiliary energy is started to perform the power supply operation, and the circuit output information D is obtained after the auxiliary energy is started until the circuit output information D is located between the critical output ranges a-B.
In one embodiment, considering that the storage battery corresponding to the auxiliary power supply device with a sufficient electric quantity value needs to be preferentially started for performing the power supply operation, the storage battery corresponding to the auxiliary power supply device needs to be sorted according to the remaining electric quantity value, and the specific sorting operation may be specifically performed as:
respectively acquiring power supply auxiliary information, wherein the power supply auxiliary information comprises a residual electric quantity value before the auxiliary energy source performs power supply operation, performing descending sorting on the auxiliary power supply information according to the size of the residual electric quantity value, setting the descending sorting order as a preset priority order, and preferentially starting the auxiliary energy source with the most residual electric quantity according to the preset priority order to perform power supply operation; and when the residual electric quantity value corresponding to the auxiliary energy for power supply operation is smaller than a preset power supply standard value, sequentially starting the residual auxiliary energy according to the priority order to perform power supply operation until the circuit output information is within a preset critical output range. For example, if the power supply auxiliary information corresponding to the auxiliary power supply devices A, B and C is 90%, 72%, and 94%, and the preset power supply standard value is 20%, the auxiliary power supply device C is first started to perform power supply operation, and when the remaining power of the auxiliary power supply device C is less than 20%, the auxiliary power supply device C is turned off, and the auxiliary power supply device a is started to perform power supply operation; the probability that the winning point equipment is damaged due to tripping in the campus caused by insufficient electric quantity of the storage battery corresponding to the auxiliary power supply equipment when the auxiliary power supply equipment is started is reduced, and therefore the stability of power supply operation of the storage battery corresponding to the auxiliary power supply equipment is improved after the auxiliary power supply equipment is started.
In an embodiment, considering that when the auxiliary power supply information is sorted according to the electric quantity value, there is a case that the electric quantity values corresponding to a plurality of pieces of power supply information are the same, the power supply information with the same electric quantity value needs to be selected, and the specific selection may be specifically performed as:
and when the electric quantity values corresponding to the auxiliary energy sources are the same, respectively acquiring historical practical times of the auxiliary energy sources, wherein the historical use times are the times of charging operation of the storage batteries corresponding to the auxiliary energy sources in preset time, and preferentially selecting the auxiliary energy sources with less historical use times for power supply operation. Make the system can carry out priority's sequencing according to the automatic auxiliary energy who is the same to the electric quantity value of historical use number of times, reduced and used the same auxiliary energy many times and lead to the battery that auxiliary energy corresponds to charge and discharge many times and lead to the probably of battery damage to the life of the battery that auxiliary energy corresponds has been promoted. For example, the electric quantity values corresponding to the auxiliary energy A, B and C are both 90%, the historical number of times of use corresponding to a is 3, the historical number of times of use corresponding to B is 2, the historical number of times of use corresponding to C is 5, the auxiliary energy B, A and C are sequentially started according to the historical practical number of times, and when only the storage battery corresponding to one auxiliary energy needs to be started for supplying power, the auxiliary energy B is preferentially selected.
In one embodiment, considering that the electric quantity of the storage battery corresponding to the plurality of auxiliary energy sources cannot support the long-time power supply operation, the electric quantity value in the storage battery corresponding to the auxiliary energy source needs to be checked, and the checking operation may be specifically performed as:
acquiring actual power consumption, calculating the ratio between the auxiliary power supply information with the maximum electric quantity value and the actual power consumption, and setting the ratio as actual auxiliary power supply time; if the actual auxiliary power supply time is not longer than the preset limit power supply time, controlling the power grid to continue to supply power; otherwise, the auxiliary energy sources are sequentially started to perform power supply operation according to the preset priority sequence until the circuit output information is within the preset critical output range. Under having reduced special weather, the operation of charging can't be carried out to the battery that corresponds to supplementary power supply facility, and the electric quantity in the battery that leads to is not enough then makes the unable long-time operation of charging of battery that the auxiliary energy corresponds, leads to the outage of electricity utilization facility in the school district for the possibility of electricity utilization facility damage makes the operation of charging that the battery that the auxiliary energy corresponds can be stable. For example, when the actual power consumption is 1000 kilowatt hours, the electric quantity value corresponding to the auxiliary power supply information is 10000 kilowatts, the corresponding actual auxiliary power supply time is 10 hours, and if the preset limit power supply time is 20 hours, the power grid is continuously used for supplying power; and if the preset limit power supply time is 8 hours, performing power supply operation by using a storage battery corresponding to the auxiliary energy.
In one embodiment, in consideration of the fact that schools have cold and hot holidays, the power consumption of schools can be met only by using the storage batteries corresponding to the auxiliary energy sources for power supply operation, historical power consumption of schools needs to be counted, and the counting operation can be specifically executed as follows:
the method comprises the steps of obtaining historical power supply information, wherein the historical power supply information comprises historical power supply power, respectively obtaining auxiliary power supply information, calculating a ratio between an electric quantity value corresponding to the auxiliary power supply information and the historical power supply power, setting the ratio as historical duration, obtaining historical power utilization time, wherein the historical power utilization time is the total time when the historical power supply power is not zero, and if the historical duration is longer than the historical power utilization time, controlling an auxiliary energy source to replace a power grid to carry out power supply operation. The system can be automatically switched to the auxiliary energy meeting the standard to supply power to the electric equipment in the school zone according to the historical power supply information, so that the expenditure of the electric charge of the school during the periods of cold and summer vacations is reduced. For example, if the historical power supply information is 300 kilowatt hours, the auxiliary power supply information is 12000 kilowatts, the corresponding historical duration time is 40 hours, and the preset historical power consumption time is 24 hours, the auxiliary energy is controlled to replace the power grid for power supply operation.
In one embodiment, considering that the actual power may change, the actual power needs to be monitored, and the specific monitoring operation may be performed as:
acquiring actual power utilization power, calculating a ratio between the actual power utilization power and the duration time, setting the ratio as an actual power utilization change rate, acquiring a historical power utilization change rate, calculating a difference value between the actual power utilization change rate and the historical power utilization change rate, setting the difference value as an actual power utilization change rate difference value, and if the actual power utilization change rate difference value is larger than a preset critical power utilization difference value, still using a power grid for power supply operation; otherwise, the auxiliary energy is controlled to replace the power grid for power supply operation. The system can switch the auxiliary energy power supply into the power grid power supply in time according to the actual power utilization, and the possibility that the auxiliary energy power supply time is insufficient due to overlarge power utilization in the same day to cause tripping and further damage power utilization facilities is reduced. For example, when the actual power consumption is 100 kilowatt-hour and the duration is 10 hours, the actual power consumption change rate is 10, the obtained historical power consumption change rate is 7, the actual power consumption change rate difference value is 3, and the preset critical power consumption difference value is 2, the power grid is started to perform power supply operation; and if the preset critical power utilization difference value is 5, continuing to use the storage battery corresponding to the auxiliary energy source for power supply operation.
In one embodiment, in consideration of the possibility of damage to the auxiliary energy source and the corresponding storage battery, the state of the auxiliary energy source and the corresponding storage battery needs to be monitored, and the specific monitoring may be performed as follows:
after the auxiliary power supply information is respectively acquired, the auxiliary power supply information is compared with a preset abnormal electric quantity range, if the auxiliary power supply information is located in the preset abnormal electric quantity range, the corresponding auxiliary power supply information is stored in a preset abnormal electric quantity recording library, the continuous occurrence recording times corresponding to different auxiliary power supply information in the preset abnormal electric quantity recording library are counted, and if the continuous occurrence recording times corresponding to the auxiliary power supply information are greater than the preset limit abnormal recording times, abnormal prompt information is sent to an intelligent terminal of a worker. The working personnel can maintain or replace the abnormal auxiliary energy and the corresponding storage battery in time through the abnormal prompt information. For example, if the preset abnormal electric quantity range is 0-10 kilowatt-hour, and the auxiliary power supply information 200 kilowatt-hour, 68 kilowatt-hour and 3 kilowatt-hour obtained within the specified time is obtained, the auxiliary power supply information corresponding to 3 kilowatt-hour is recorded, the number of times of continuous occurrence in the corresponding abnormal electric quantity record library is inquired to be 3 times, and the preset limit abnormal record number of times is 3 times, the auxiliary energy corresponding to 3 kilowatt-hour and the abnormal information related to the corresponding storage battery are sent to the intelligent terminal of the worker.
The implementation principle of the embodiment of the application is as follows: acquiring power output information in real time, and comparing the power output information with a preset critical output range; when the circuit output information is within the critical output range, controlling the power grid to continue to supply power; otherwise, performing descending order according to the electric quantity values corresponding to the auxiliary energy sources, and preferentially calling the storage batteries corresponding to the auxiliary energy sources with large electric quantity values for power supply operation; when the electric quantity values corresponding to the auxiliary energy sources are the same, preferentially calling the electric quantity values corresponding to the auxiliary energy sources with less historical use times to perform power supply operation; meanwhile, actual power utilization power is obtained, actual auxiliary power supply time is calculated, and if the actual auxiliary power supply time is not longer than preset limit power supply time, the power grid is controlled to continue power supply operation; otherwise, starting the auxiliary energy source to supply power until the circuit output information is within the preset critical output range.
