Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail and completely with reference to the following embodiments and accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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.
In the prior art, part of photovoltaic power plants choose to clean the photovoltaic modules in a fixed cycle. The cleaning mode is very modular, the photovoltaic module with serious dust deposition can not be cleaned at the first time, and the photovoltaic module with not serious dust deposition can be cleaned unnecessarily along with the period. It is obvious that the flexible adjustment cannot be performed in combination with the actual situation, and the benefit cannot be maximized. And another photovoltaic power station selects to install a dust detector so as to detect the dust deposition degree of the photovoltaic module. Therefore, the photovoltaic module can be cleaned in combination with actual conditions. However, the installation of the dust detector itself causes additional hardware cost, and still causes a certain cost problem.
In view of the above, the present invention provides a method and an apparatus for determining photovoltaic cleaning, which can determine whether to clean a photovoltaic power station in combination with the power generation efficiency of the photovoltaic power station. The benefit of photovoltaic power plant has been guaranteed, has avoided extra hardware to deploy simultaneously.
Referring to fig. 1, a specific embodiment of a method for determining photovoltaic cleaning according to the present invention is shown. In this embodiment, the method specifically includes the following steps:
The target photovoltaic power station, i.e., the object for which cleaning is required in this embodiment, is determined. The efficiency value of the target photovoltaic power station is referred to in the art as PR value (i.e., Performance Ratio), or may be referred to as "comprehensive power generation efficiency". Is an important performance parameter in the photovoltaic working process. There are specific provisions in the art for the calculation of the PR value, which are not described herein.
The benchmarking efficiency value in this step is an efficiency value that the target photovoltaic power station should theoretically (or under the assumption that no dust is deposited), and can be regarded as a rated standard of the target photovoltaic power station. And the actual efficiency value is the efficiency actually calculated in the working process of the target photovoltaic power station.
And 102, determining an efficiency loss value corresponding to the target photovoltaic power station at the current day according to the benchmarking efficiency value and the actual efficiency value.
It is considered that the photovoltaic deposition is a factor that mainly affects the efficiency of the target photovoltaic power plant. In the presence of dust deposition, the actual efficiency value of the target photovoltaic power station may be reduced relative to the benchmarking efficiency value. In this embodiment, the difference between the benchmarking efficiency rate and the actual efficiency rate is determined as the efficiency loss rate. The efficiency loss value means the efficiency loss of the target photovoltaic power station due to the deposition of dust.
And 103, determining the corresponding revenue loss of the target photovoltaic power station at the current day according to the efficiency loss value.
For a photovoltaic power plant, the loss of efficiency of the target photovoltaic power plant means the loss of revenue. Therefore, in this embodiment, the corresponding revenue loss of the target photovoltaic power station on the current day is further determined according to the efficiency loss value. Usually, the loss of power generation caused by dust deposition can be estimated through the efficiency loss value, and the corresponding loss of revenue can be determined by further combining the electricity price. It will be appreciated that this loss of revenue also corresponds to the revenue that would theoretically be gained in addition to the cleaning of the target photovoltaic power plant.
And 104, determining a cleaning cost threshold corresponding to the target photovoltaic power station.
In this embodiment, the cleaning cost threshold may refer to a cost brought by cleaning the target photovoltaic power station.
And 105, when the yield loss is larger than the cleaning cost threshold value, determining the target photovoltaic power station as the photovoltaic power station to be cleaned.
From a cost and revenue perspective, the loss of revenue may be considered as the additional revenue that will be gained after cleaning the target photovoltaic power plant. And the cleaning cost threshold is the cost for cleaning the target photovoltaic power station. Obviously, if the loss of revenue is greater than the cleaning cost threshold, the target photovoltaic power station is cleaned at the moment, and the profit is greater than the cost, namely the profitability behavior. And otherwise, if the profit loss is smaller than the cleaning cost threshold value, cleaning the target photovoltaic power station, wherein the profit is smaller than the cost, namely the profit behavior.
Therefore, in this embodiment, when the revenue loss is greater than the cleaning cost threshold, the target photovoltaic power station is determined as the photovoltaic power station to be cleaned, that is, the target photovoltaic power station is considered to need to be cleaned, and additional profit is generated when the target photovoltaic power station is cleaned.
According to the technical scheme, the beneficial effects of the embodiment are as follows: the actual efficiency value based on the target photovoltaic power station is realized, the loss of revenue caused by the existing dust deposition is determined, and the loss of revenue and the cleaning cost threshold value are compared, so that whether the target photovoltaic power station is cleaned or not is determined by combining with the actual condition, the revenue of the photovoltaic power station is improved, and meanwhile, the cost caused by additionally deploying hardware is avoided.
Fig. 1 shows only a basic embodiment of the method of the present invention, and based on this, certain optimization and expansion can be performed, and other preferred embodiments of the method can also be obtained.
Fig. 2 shows another specific embodiment of the method for determining photovoltaic cleaning according to the present invention. The present embodiment is further developed on the basis of the foregoing embodiments. The method specifically comprises the following steps:
The above steps 201 to 202 are the same as those in the embodiment shown in fig. 1, and the description thereof will not be repeated.
It should be noted that, in the present embodiment, it is preferably determined whether the benchmarking efficiency rate and the actual efficiency rate satisfy preset conditions. And if the target efficiency value and the actual efficiency value meet preset conditions, determining the target photovoltaic power station as the cleaned photovoltaic power station.
It is generally recognized that the re-deposition of ash from a target photovoltaic power plant after cleaning is a particular rule. That is, the efficiency drop curve of the target photovoltaic power plant after cleaning is also specific. Therefore, whether the actual efficiency value meets the descending rule or not can be determined by judging whether the flagpole efficiency value and the actual efficiency value meet preset conditions or not.
If the above rule is satisfied, the deposition condition is considered to be normal, and the preset condition is not satisfied, the process may proceed to step 203. Otherwise, if the rule is not met, the accumulated dust of the target photovoltaic power station is influenced by other factors. Generally, rainwater can generate a natural cleaning effect on photovoltaic, namely, the law of dust deposition of a target photovoltaic power station is changed, so that the dust deposition of the target photovoltaic power station is influenced. Therefore, in this embodiment, when the actual efficiency value does not conform to the above-mentioned descent rule, it is considered that the preset condition is satisfied, that is, it is considered that the rainwater naturally cleans the target photovoltaic power station, and manual cleaning is not required for a while. The target photovoltaic power plant can thus be determined as a cleaned photovoltaic power plant.
And 203, determining a corresponding electric quantity loss value according to the efficiency loss value.
In this embodiment, the standard daily power generation amount of the target photovoltaic power station, that is, the power generation amount that the target photovoltaic power station can generate on the current day in theory, may be determined. The standard daily power generation amount depends on the performance of the target photovoltaic power station and the illuminance of the current day, and is a parameter which can be calculated conventionally in the field, and is not described herein. And further determining the product of the efficiency loss value and the standard daily generated energy as the electric quantity loss value. The power loss value means a value at which the efficiency of the target photovoltaic power station decreases due to deposition of dust, resulting in a decrease in power generation amount.
And 204, determining the profit loss according to the electric quantity loss value.
In this embodiment, the product of the electric quantity loss value and the electricity price is determined as the profit loss. The loss of revenue means a reduction in efficiency of the target photovoltaic power plant due to deposition of dust, resulting in a reduced value of revenue.
It should be noted that, for some photovoltaic power stations, a part of the generated electricity is supplied for local use, and another part of the generated electricity is uploaded to the grid system. The two parts have different electricity prices. Then separate calculations are also made in proportion to the lost revenue at this time. Specifically, the revenue loss may be considered as an electricity loss value, a local energy supply ratio, a local electricity price, and an electricity loss value, and uploaded to the grid ratio, a grid electricity price.
The initial cleaning cost in this embodiment may refer to the cost incurred to clean the target photovoltaic power plant. In some cases, the raw cleaning cost may be used directly as a cleaning cost threshold. However, in this embodiment, it is necessary to preset a corresponding critical cleaning coefficient additionally, and determine the product of the original cleaning cost and the critical cleaning coefficient as the cleaning cost threshold.
Because in practical situations, after determining that the target photovoltaic power plant needs to be cleaned, the actual cleaning is not necessarily able to be performed on the same day or the next day. During which there is often a certain time interval. The time interval can be taken into account by setting the critical cleaning factor so as to decide to clean the target photovoltaic power station in advance for a certain time. It is ensured that on the day of cleaning, profit can be produced precisely from cleaning the target photovoltaic power plant. In this embodiment, the critical cleaning factor may be set to 95%.
And step 206, when the yield loss is larger than the cleaning cost threshold value, determining the target photovoltaic power station as a photovoltaic power station to be cleaned.
This step is the same as that in the embodiment shown in fig. 1, and will not be repeated here.
Fig. 3 shows a specific embodiment of the photovoltaic cleaning determination device according to the present invention.
