All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following describes a control method and device of an air conditioner and the air conditioner in the invention with reference to fig. 1-3.
The execution main body of the control method of the air conditioner in the embodiment of the present invention may be a controller, and of course, in other embodiments, the execution main body may also be a controller, and the type of the execution main body is not limited herein. The following describes a control method of an air conditioner according to an embodiment of the present invention with a controller as an execution subject.
As shown in fig. 1, the method for controlling an air conditioner according to the embodiment of the present invention mainly includes step 110, step 120, step 130, and step 140.
And 110, controlling the air conditioner to supply power through the wind and light energy storage system at the first target moment.
The first target time is a time when the air conditioner is operated.
The wind-solar energy storage system provided by the embodiment of the invention can comprise solar photovoltaic power generation equipment, a wind driven generator and a storage battery pack. The air conditioner of the embodiment of the invention at least comprises an indoor unit, an outdoor unit and a compressor.
In some embodiments, an inverter is disposed between the storage battery pack of the wind-solar energy storage system and the air conditioner, and the inverter can convert direct current output by the storage battery pack into alternating current to supply power to the air conditioner.
In other embodiments, the air conditioner is powered by direct current. A rectifier is arranged between the air conditioner and the commercial power, and the rectifier can convert the alternating current on the commercial power into direct current to supply power to the air conditioner. The indoor unit, the outdoor unit and the frequency converter in the air conditioner are all provided with transformers so as to realize the adjustment of the frequency converter and the rotating speeds of the indoor unit and the outdoor unit.
At the first target moment, the utilization rate of new energy can be improved by supplying power to the air conditioner through the wind and light energy storage system.
And 120, determining the estimated power generation amount of the wind and light energy storage system from the first target moment in the target time period, and determining the first stored electric quantity of the wind and light energy storage system at the first target moment.
It should be noted that the target time period may be several hours, one day, one week, etc., and the time length of the target time period is not limited herein.
Considering that the photovoltaic power generation in the wind and light energy storage system is more stable and sufficient, the estimated power generation amount of the wind and light energy storage system can be determined according to the time of receiving the sunlight irradiation.
For example, when the target period is one day, the time at which the illumination can be effectively received may be eight am to five pm. If the first target time is the afternoon, the estimated power generation amount of the wind and light energy storage system from the first target time in the target time period is from the afternoon to the five afternoon.
It is understood that, in some embodiments, the first storage capacity of the wind-solar energy storage system at the first target time may be determined by receiving a value reported by a power management system of the storage battery pack.
And step 130, determining a second target moment based on the target power of the air conditioner, the first stored electric quantity, the estimated power generation quantity and the first target moment.
The target power of the air conditioner is the power of the air conditioner when the air conditioner is powered by the wind-solar energy storage system at the first target time.
In some embodiments, the target power may be a preset power value, and the air conditioner may directly read the stored target power value after being turned on at the first target time, and control the air conditioner to operate at the target frequency.
In other embodiments, the target power may also be obtained from historical operating data of the air conditioner. For example, the target power is a power value of the air conditioner at the last time of turning off.
It can be understood that historical operating data of the air conditioner can be recorded, and when the air conditioner is started at the first target moment, historical operating data of the air conditioner can be read, and the target power can be determined.
It should be noted that the estimated power generation amount of the wind and light energy storage system can be used for charging the wind and light energy storage system and also can be used for supplying power to the air conditioner.
And at a second target moment, switching to simultaneously supplying power to the air conditioner through the commercial power and the wind-light energy storage system.
Under the condition, the storage capacity of the wind and light energy storage system needs to be kept at a higher level for the need of time, and meanwhile, the target power, the first storage capacity of the wind and light energy storage system at the first target moment and the estimated generated energy need to be combined to reasonably determine the time for the air conditioner to supply power through the wind and light energy storage system and further determine the second target moment.
In some embodiments, the second target time may be confirmed by the following procedure.
And under the condition that the first stored electric quantity is larger than or equal to a first preset value, determining a first target working time length of the air conditioner based on the estimated electric energy generation quantity and the target power.
It should be noted that the first preset value is used for indicating the amount of the electric quantity of the wind and light energy storage system, and the first preset value can be set to different values according to different practical situations.
For example, the first preset value may be 90% or 100% of the full electric quantity of the wind and light energy storage system.
In this case, the residual electric quantity of the wind and light energy storage system is large, and the estimated generated energy of the wind and light energy storage system can be used for supplying power to the air conditioner.
Of course, in other embodiments, a part of the estimated power generation amount may be used to supply power to the air conditioner, and the rest may be used to fully charge the wind and light energy storage system.
Under the condition, the first target working time that the air conditioner can work through the estimated power generation amount can be determined according to the estimated power generation amount and the estimated power of the air conditioner.
After the first target operating duration is determined, a second target time may be determined based on the first target time and the first target operating duration.
In the embodiment, when the first stored electric quantity of the wind and light energy storage system is large, estimated generated energy is reasonably distributed to supply power to the air conditioner, so that the new energy utilization efficiency is improved, and the wind and light energy storage system is ensured to have large stored electric quantity.
In other embodiments, the second target time may also be confirmed by the following procedure.
In this embodiment, the second amount of stored power is determined when the first amount of stored power is less than the first preset value.
In this case, the first stored electric quantity is smaller than the first preset value, and the remaining electric quantity in the wind and light energy storage system is not large.
It should be noted that the second stored electric quantity is a difference between the full electric quantity of the wind and light energy storage system and the first stored electric quantity.
In this case, considering that the remaining power of the wind and light energy storage system is low, a part of the estimated power generation amount needs to be used for supplementing the power to the wind and light energy storage system.
In the embodiment, the estimated power supply amount of the wind and light energy storage system can be determined based on the estimated power generation amount and the second stored power amount.
It is understood that the estimated power supply amount may be a difference between the estimated power generation amount and the second stored power amount.
And after the estimated power supply amount of the wind and light energy storage system is determined, determining a second target working time length of the air conditioner based on the estimated power supply amount and the target power.
It can be understood that the second target operation time is the time for which the air conditioner operates at the target power under the condition that the wind and light energy storage system provides the estimated power supply amount to the air conditioner.
After the second target operating duration of the air conditioner is determined, the second target time may be determined based on the first target time and the second target operating duration.
In other words, the time after the first target time and the second target operating time is the second target time.
In the embodiment, when the first stored electric quantity of the wind and light energy storage system is small, the estimated generated energy is reasonably distributed to supply power to the air conditioner, and a part of electric quantity is reserved to charge the wind and light energy storage system, so that the wind and light energy storage system can have more stored electric quantity while the utilization efficiency of new energy is improved.
And 140, controlling the air conditioner to simultaneously supply power through the wind-solar energy storage system and the commercial power at a second target moment.
It is understood that, in the present embodiment, from the second target time, the wind-solar energy storage system and the commercial power supply simultaneously supply power to the air conditioner.
It is understood that, in some embodiments, the wind and light energy storage system may supply power to the air conditioner when the amount of electricity of the wind and light energy storage system is large, and switch to the commercial power supply when the amount of electricity of the wind and light energy storage system is small.
Alternatively, in other embodiments, the power may be supplied by the utility power when the air conditioner is in high-power operation, and by the wind and light energy storage system when the air conditioner is in a low-frequency and low-power consumption state.
According to the control method of the air conditioner, the estimated power generation amount of the wind and light energy storage system is evaluated, so that power supply is switched to be carried out through the commercial power and the wind and light energy storage system at a proper time, the wind and light energy storage system can be reasonably utilized for power supply, the utilization rate of new energy of the wind and light energy storage system is improved, and the air conditioner is guaranteed to have sufficient and stable power supply.
In some embodiments, at step 140: after the air conditioner is controlled to be powered simultaneously by the wind-solar energy storage system and the mains supply at the second target moment, the control method of the air conditioner in the embodiment of the invention further comprises the following steps: determining a mains voltage; and reducing the working frequency of the compressor to the first frequency under the condition that the mains voltage is less than a third preset value.
In this embodiment, the voltage condition of the commercial power for the air conditioner operation can be detected to distinguish the normal voltage condition from the under-voltage condition. Under the condition of normal voltage, the air conditioner provided by the embodiment of the invention operates at normal frequency under a corresponding working mode.
Under the condition that the mains voltage is under-voltage, namely under the condition that the mains voltage is smaller than a third preset value, the air conditioner provided by the embodiment of the invention operates according to the condition that the frequency of the compressor is reduced to the first frequency, so that the power consumption of the system is reduced. For example, the first preset value may be 95% of the rated voltage of the air conditioner.
It can be understood that the commercial power voltage is low to a certain extent, the air conditioner current is large, and the air conditioner can carry out current protective frequency reduction. Under the condition that the current of the air conditioner is not reduced automatically, the frequency of the compressor of the air conditioner is reduced to the first frequency, so that the electric energy can be saved.
In some embodiments, the first frequency may be set as an empirical value, and in other embodiments, the first frequency may be set synthetically according to the generated power of the wind-solar energy storage system, and the specific setting manner of the first frequency is not limited herein.
In the embodiment, the frequency of the compressor of the air conditioner is reduced under the condition that the mains voltage is under-voltage, so that electric energy can be saved.
In some embodiments, the step of determining the estimated power generation amount of the wind and light energy storage system from the first target time in the target period specifically includes the following processes.
The illumination radiation intensity information and the wind speed information from the first target moment in the target time period can be determined based on weather forecast information of the place where the wind and light energy storage system is located.
In some embodiments, the real-time illumination intensity prediction value and the real-time wind speed prediction value of the location of the target area at each time interval can be determined according to weather forecast information, so that the real-time illumination intensity prediction value is determined as the real-time illumination intensity, and the real-time wind speed prediction value is determined as the real-time wind speed.
In other embodiments, an illumination intensity detector may be employed to detect real-time illumination intensity and an anemometer may be employed to determine real-time wind speed.
Of course, in other embodiments, the real-time illumination intensity and the real-time wind speed may be determined in other manners, and are not limited herein.
After determining the real-time illumination intensity and the real-time wind speed, the real-time solar power may be determined based on the real-time illumination intensity. It will be appreciated that the solar power may be determined in particular according to the particular parameters of the solar photovoltaic power plant and the connected load conditions.
The real-time wind power may be determined based on the real-time wind speed. It will be appreciated that the wind power may be determined in particular in dependence on specific parameters of the wind turbine and the load conditions of the connection.
Further, the real-time generated power may be determined based on the real-time solar power and the real-time wind power.
In some embodiments, the sum of the real-time solar power and the real-time wind power may be directly determined as the real-time generated power.
It will be appreciated that solar power and wind power may be determined from the real-time power at each time interval. For example, the power of each time period may be averaged to obtain the total average power. Or the estimated power generation amount can be determined by directly utilizing the real-time power corresponding to each time interval.
Further, the estimated power generation amount may be determined based on the solar power, the wind power, the target time period, and the first target time.
After the solar power and the wind power are determined, the estimated generated energy can be determined according to the time length of the target time period after the first target time.
In some embodiments, the solar power and the wind power are average power, and the time period available for power generation can be directly multiplied by the average power to obtain the estimated power generation amount.
In other embodiments, the real-time power corresponding to each time interval may be multiplied by the duration of each time interval to obtain the power generation amount of each time interval, so as to obtain the total estimated power generation amount.
According to the control method of the air conditioner, the solar power and the wind power are predicted through weather forecast information, and therefore the estimated power generation amount of the wind and light energy storage system can be accurately obtained.
The following describes a control device of an air conditioner according to the present invention, and the control device of an air conditioner described below and the control method of an air conditioner described above may be referred to in correspondence with each other.
As shown in fig. 2, the control apparatus of an air conditioner according to an embodiment of the present invention includes a first process module 210, a second process module 220, a third process module 230, and a fourth process module 240.
The first processing module 210 is configured to control the air conditioner to supply power through the wind and light energy storage system at a first target time;
