Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic power generation, and in particular relates to a distributed photovoltaic electricity fee analysis method, system, storage medium and electronic equipment. Background Art

[0002] The grid-connected operation modes of distributed photovoltaic assets are mainly divided into three categories: "self-generation for self-use, surplus power to the grid", "full grid-connection" and "off-grid mode". In the two modes of "self-generation for self-use, surplus power to the grid" and "off-grid mode", the asset holder needs to charge electricity fees to users. The existing electricity fee statistical analysis mainly adopts manual data collection and offline Excel spreadsheet production, and the spreadsheet needs to be repeated every month. The specific process is: first, offline meter reading is carried out to record the power generation data, and then the user signs and confirms the meter reading data, and then the power and electricity price data are manually integrated, and then the electricity bill settlement sheet is produced offline, and the electricity bill settlement sheet is sent to the user for confirmation, and finally the settlement process is promoted. Different tables need to be made for different electricity price charging modes. One charging mode is to distinguish between peak and valley electricity prices for charging, and the other is to implement a single electricity price for charging.

[0003] There are many problems with the existing methods. First, in the process of manual data collection, the data collection time span is long and the efficiency is low due to the wide distribution and dispersion of power stations. In addition, when collecting data, relevant personnel need to carefully match the corresponding meters to ensure the accuracy of the data. However, this process is prone to human matching errors, resulting in inaccurate data. Secondly, in the process of manual integration of electricity volume and electricity price, offline tables are usually used for operation. These tables often lack inheritance relationships, making it difficult for users to compare data. In this way, it is difficult for users to discover abnormal changes in the data in time, thus affecting the accuracy and reliability of the data. Finally, since different departments or personnel may use different Excel tables for calculations, this requires relevant personnel to have corresponding professional knowledge and experience to ensure the correct use of the tables. However, this practice of relying on personal professional knowledge and experience not only has human resource limitations, but also brings the risk of subjective judgment. For example, different personnel may have different understandings and operation methods when processing data, resulting in inconsistent data processing results.

[0004] In general, the existing technologies and methods face problems such as human resource limitations, low efficiency, and proneness to errors when analyzing electricity bill data. These problems not only affect the efficiency and accuracy of data processing, but also increase the complexity and uncertainty of data analysis. Summary of the invention

[0005] In view of the above problems, the present invention proposes a distributed photovoltaic electricity cost analysis method, system, storage medium and electronic device.

DETAILED DESCRIPTION

[0058] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] Figure 1 : is a flow chart of a distributed photovoltaic analysis method provided by an embodiment of the present invention. In one embodiment, the method specifically includes the following steps:

[0060] S101: Obtain current electricity consumption information, generate and review and confirm current meter reading information.

[0061] The system automatically obtains the current period's electricity consumption information at a preset frequency. The electricity consumption information includes the reading numbers for four time periods, namely, peak (abbreviated as "peak"), high (abbreviated as "peak"), flat (abbreviated as "flat") and low (abbreviated as "valley"), and also includes the total reading number, which is the sum of the reading numbers for the four time periods: peak, flat and valley.

[0062] The system automatically completes the meter attribute information, meter reading time, cycle, approval flow node and verification rules, and generates the meter reading information for this period in a unified manner based on the current electricity consumption information. The meter attribute information includes meter type, meter number, meter multiplier and meter status; the meter types include power generation meters and online meters; the verification rule is that the reading numbers of the peak, flat, valley and total of this period shall not be lower than the reading numbers of the peak, flat, valley and total of the previous period.

[0063] After generating the current meter reading information, the user reviews and confirms the meter reading information. If the user has any objection to the meter reading information, the meter reading information will be rejected, and the staff will revise the meter reading information and then submit it to the user for review again; if the user has no objection to the meter reading information, the meter reading information generated by the system will be used as the data basis for executing step S102.

[0064] S102: Obtain the meter reading information of the previous period, and calculate the peak, flat, valley and total interval electricity in the power generation meter and the online meter according to the electricity consumption information in the previous period and the electricity consumption information and the meter multiplier in the current period.

[0065] According to the electricity consumption information in the previous meter reading information and the electricity consumption information and meter multiplier in the current meter reading information, the interval electricity consumption in the four periods of peak, peak, flat and valley in the power generation meter and the online meter are calculated respectively, and the calculation formula of the interval electricity consumption of the power generation meter and the online meter is the same, as follows:

[0066] Peak interval electricity = (peak reading value of this period - peak reading value of the previous period) * meter multiplier;

[0067] Peak interval electricity consumption = (peak reading value of this period - peak reading value of the previous period) * meter multiplier;

[0068] Electricity in flat section = (current flat section reading value - previous flat section reading value) * meter multiplier;

[0069] Electricity in off-peak interval = (low-peak reading value of this period - low-peak reading value of the previous period) * meter multiplier;

[0070] Total interval electricity = (total reading of this period - total reading of the previous period) * meter multiplier.

[0071] The difference in meter types results in different meter multipliers. Therefore, when calculating according to the above formula, the meter multipliers need to be distinguished according to the meter type.

[0072] After calculating the interval electricity consumption of the peak, peak, flat and valley periods and the total interval electricity consumption in the power generation meter and the online meter, check whether the above calculated data meets the requirements according to the following formula. The calculation formula is: peak interval electricity consumption + high peak interval electricity consumption + flat interval electricity consumption + valley interval electricity consumption - total interval electricity consumption. Obtain the calculation result and check whether the calculation result is less than or equal to 0.04. If it meets the requirements, save the interval electricity consumption of the peak, peak, flat and valley periods and the total interval electricity consumption in the power generation meter and the online meter. If it does not meet the requirements, the staff will check whether the meter readings are entered incorrectly. After checking, calculate the interval electricity consumption of the peak, peak, flat and valley periods and the total interval electricity consumption in the power generation meter and the online meter according to the above method, and check until it meets the requirements.

[0073] S103: Calculate the peak, peak, flat, valley and total interval power consumption according to the peak, peak, flat, valley and total interval power consumption in the power generation meter and the grid-connected meter.

[0074] According to the peak, peak, flat, valley and total interval electricity in the power generation meter and the grid-connected meter, the peak, peak, flat, valley and total interval consumption electricity are calculated by the following formula, as follows:

[0075] Peak interval power consumption = peak interval power consumption of power generation meter - peak interval power consumption of online meter;

[0076] Peak-interval power consumption = peak-interval power consumption of power generation meter - peak-interval power consumption of online meter;

[0077] Electricity consumed in the flat section = Electricity consumed in the flat section by the power generation meter - Electricity consumed in the flat section by the grid-connected meter;

[0078] The amount of electricity consumed in the off-peak period = the amount of electricity consumed in the off-peak period of the power generation meter - the amount of electricity consumed in the off-peak period of the online meter;

[0079] Total interval power consumption = total interval power consumption of power generation meter - total interval power consumption of grid-connected meter.

[0080] S104: Obtain and calculate the settlement electricity prices for peak, peak, flat and valley periods according to the peak, peak, flat and valley electricity sales prices and power station contract discount information.

[0081] The peak, on-peak, flat and valley electricity selling prices are maintained by the staff after reviewing the meter reading information. Specifically: for power stations that distinguish between peak, on-peak, flat and valley electricity prices, the peak, on-peak, flat and valley electricity selling prices in the market for that month are maintained respectively; for power stations with a unified electricity price, only a single electricity selling price in the market for that month is maintained.

[0082] Power station contract discount information is maintained by staff.

[0083] After obtaining the above-mentioned peak, on-peak, flat and off-peak electricity sales prices and power station contract discount information, calculate the peak, on-peak, flat and off-peak settlement electricity prices.

[0084] S105: Calculate and summarize the electricity charges receivable during the peak, peak, flat and valley periods according to the peak, peak, flat and valley period consumption and the settlement electricity prices during the peak, peak, flat and valley periods to obtain the total electricity charges receivable.

[0085] According to the peak, peak, flat and valley interval consumption and the peak, peak, flat and valley settlement electricity prices, calculate and summarize the peak, peak, flat and valley electricity charges to obtain the total electricity charges receivable, as follows:

[0086] Total electricity charges receivable = electricity consumed in peak period * peak settlement electricity price + electricity consumed in peak period * peak electricity price + electricity consumed in normal period * normal settlement electricity price + electricity consumed in valley period * valley settlement electricity price.

[0087] S106: Obtain the adjusted electricity fee, and calculate the settlement electricity fee based on the total electricity fee to be receivable and the adjusted electricity fee.

[0088] The electricity fee adjustment is maintained by the staff according to the actual collection and payment needs. After obtaining the adjusted electricity fee, the settlement electricity fee is calculated based on the total electricity fee receivable and the adjusted electricity fee. The calculation formula is as follows:

[0089] Settlement electricity charges = total electricity charges receivable + adjusted electricity charges.

[0090] Optionally, the adjusted electricity fee can be empty, that is, the staff can choose not to maintain the adjusted electricity fee. If the adjusted electricity fee is not maintained, it is also calculated according to the formula of settlement electricity fee = total electricity fee receivable + adjusted electricity fee, but in the actual calculation, the adjusted electricity fee = 0.

[0091] After executing the above steps S101-S106, the system will generate an electricity bill settlement sheet according to the information generated during the execution of the above steps. The information in the electricity bill settlement sheet includes: settlement sheet period, basic information of the power station, meter reading time, meter type, meter number, meter multiplier, interval electricity consumption, interval consumption electricity, electricity sales price, settlement electricity price, electricity charges receivable, adjusted electricity charges and settlement electricity charges.

[0092] The embodiment of the present invention also provides a distributed photovoltaic electricity fee analysis system, such as Figure 2 As shown, including:

[0096] The settlement electricity price calculation module 204 is used to obtain and calculate the settlement electricity prices of peak, peak, flat and valley hours according to the peak, peak, flat and valley electricity sales prices and power station contract discount information.

[0097] The total electricity charges receivable calculation module 205 is used to calculate and summarize the electricity charges receivable during peak, peak, flat and valley periods according to the peak, peak, flat and valley interval consumption electricity consumption and the peak, peak, flat and valley settlement electricity prices to obtain the total electricity charges receivable.
