Detailed Description
The invention will be further elucidated and described with reference to the embodiments and drawings of the specification:
Referring to fig. 1, a method for calculating a maximum demand cost-saving space of industrial and commercial electric power includes the following steps:
Step S100: historical data of a user is obtained, wherein the historical data comprises transformer capacity and historical electric power. The transformer capacity of the main inlet line in a period of time in the past and historical electric power data collected at each moment of the main inlet line are retrieved through a database.
Referring to fig. 2, step S200: the specific steps of obtaining the historical maximum demand value according to the electric power at each moment are as follows:
Step S210: and acquiring historical electric power, and grabbing the average value of the granularity of 1 min/point within 15 min.
Step S220: and judging whether the average value in all 15min of the round robin is finished.
step S230: if the round robin is not finished, the round robin data is continuously carried out until the maximum average value is obtained and recorded as the maximum demand.
step S240: and if the round robin is finished, acquiring the demand price and the capacity price. The demand electricity price and the capacity electricity price in the embodiment are directly obtained through the database interface of the power department. The most accurate electricity price data can be obtained through the interface. The problem that final electricity charge data are abnormal due to the fact that the electricity price of a worker is not changed in time is avoided.
meanwhile, the embodiment also obtains the maximum demand of a single incoming line as the maximum demand of the incoming line. For subsequent queries.
step S300: it is determined whether the maximum demand is below a rated value for the transformer capacity. The rated value of the transformer capacity in this embodiment is 40% of the transformer capacity.
Substep S310: and if the maximum demand is lower than 40% of the transformer capacity, reporting the value of the transformer capacity of 40% as the maximum demand. The step strictly executes the national relevant policy requirements, namely, when the applied maximum demand verification value is lower than 40% of the sum of the transformer capacity and the high-voltage motor capacity, the maximum demand of the contract is verified according to 40% of the sum of the capacities. Therefore, step S300 will need to add an algorithm that determines whether the maximum demand is below 40%, and forces the maximum demand to be recorded as 40% transformer capacity when the maximum demand is below 40% of the transformer capacity. And (4) really combining with actual regulation rules to assign the maximum demand.
Substep S320: and if the maximum demand is higher than 40% of the capacity of the transformer, keeping the maximum demand for reporting. This part is the same as the maximum demand acquisition in the prior art.
step S400: and respectively calculating the maximum demand electric charge and the transformer capacity electric charge according to the maximum demand electric charge and the transformer capacity electric charge. The actual electric charge of the two charging modes is calculated from the practical angle, and the charging method is closer to the relevant policy, so that the data of the maximum demand charging mode is more accurate.
step S500: and judging whether the capacity electric charge-maximum demand electric charge of the transformer is more than 0. The profit and loss results generated by the maximum demand charging mode relative to the transformer capacity charging mode can be clearly displayed through a simple comparison algorithm.
substep S510: and when the capacity electric charge of the transformer and the maximum demand electric charge are greater than 0, namely the profit is positive, the maximum demand space exists for the user adopting the maximum demand charging mode. Correspondingly numbering the output incoming lines, wherein the user has a maximum demand space; at the same time, basic information will also be presented: the maximum demand of a user, the capacity of a transformer, and unit electricity price and electricity charge of two modes; and electricity fee information: the user adopts the saved electric charge under the maximum demand declaration mode.
Substep S520: and when the capacity electric charge of the transformer and the maximum demand electric charge are less than 0, namely the profit is negative, the maximum demand space does not exist for the user adopting the maximum demand charging mode. Correspondingly numbering the output incoming lines, wherein the user does not have a maximum demand space; at the same time, basic information will also be presented: the maximum demand of a user, the capacity of a transformer, and unit electricity price and electricity charge of two modes; and electricity fee information: and the user adopts the maximum demand reporting mode to report the lost electric charge.
Step S500 allows the user to intuitively know the profit and loss of the maximum demand charging method.
the embodiment may also set the profit and loss calculation to be performed in a charging manner of the transformer capacity. The method steps are as above, and the change is only to replace the calculation in step S500 with "maximum demand power rate — whether the transformer capacity power rate is greater than 0".
Preferably, there are two types of round-robin in step S220:
The first round-robin mode is a block-type maximum demand calculation mode: accumulating the pulse numbers from 1min to 15min, multiplying the pulse numbers by the equivalent of the pulse electric energy (which refers to the electric energy value represented by each pulse), dividing the pulse numbers by 15min to obtain a demand value P1, storing the demand value P1 in a storage unit with the maximum demand, calculating a demand interval from 16min to 30min to obtain a demand value P2, comparing a second calculated value P2 with P1, and if P2 is greater than P1, storing P2 in the storage unit with the maximum demand instead of P1, and so on, keeping the maximum value of the average power of 15min in the storage unit with the maximum demand.
The second round-robin mode is a slip-type maximum demand calculation mode: and accumulating the pulse numbers from 1min to 15min, multiplying the pulse numbers by the equivalent of the electric energy of the pulse (the electric energy value represented by each pulse), dividing the pulse numbers by 15min to obtain a demand value P1, storing the demand value in a storage unit with the maximum demand, and calculating the demand value for the second time, namely calculating the average power from (1+ t) th min to (15+ t) th min, wherein t is the time of a slip interval. And (4) calculating the average power from (1+ nt) min to (15+ nt), comparing the calculated values each time, and storing the maximum value in the storage unit with the maximum demand.
the maximum demand of a certain plant is calculated by adopting a range type maximum demand calculation mode, and the result is shown in table 1.
Table 1: maximum demand calculation result of certain factory
Therefore, the maximum demand is 640.92kw at times 8:45-9: 00.
In combination with a certain utility price: maximum demand electricity rate: 32-membered/kWh; capacity electricity price: 23 yuan/kWh; and transformer capacity of the consumer: 1250 KVA.
First it can be judged that the maximum demand is greater than 40% of the transformer capacity.
Namely: maximum demand 640.92 > 40% transformer capacity 1250 x 0.4;
In other words, the formula would have 640.92 as the maximum demand value. And substituting the other data into a calculation formula of the capacity electric charge-maximum demand electric charge of the transformer.
Namely: transformer capacity power price-maximum demand power price
＝1250*23-640.92*32
＝28750-20509.44＝8240.56＞0；
Therefore, it indicates that the user adopting the maximum demand charging mode has the maximum demand space. Through the simple comparison algorithm, the profit and loss results generated by the maximum demand charging mode relative to the transformer capacity charging mode can be clearly and visually displayed, namely the relatively saved electric charge is 8240.56 yuan.
The present embodiment further provides a terminal, including:
one or more processors.
A storage device to store one or more programs.
When executed by one or more processors, the one or more programs cause the one or more processors to implement the industrial and commercial power maximum demand cost-effective space calculation method as previously described.
The present embodiment also provides a computer-readable storage medium, on which a computer program is stored, which when executed by a processor implements the method for calculating the maximum demand energy saving space of industrial and commercial power as described above.
The invention provides a space calculation method for saving the maximum demand of industrial and commercial electric power, which is used for solving the historical maximum demand value according to historical data of the electric power of a user. And judging whether the maximum demand is lower than 40% of the transformer capacity, if so, declaring the maximum demand by taking the value of the transformer capacity of 40% as the maximum demand, and if so, keeping the maximum demand for declaration. And (4) assigning the maximum demand by combining with the actual regulation rule. The maximum demand electricity charge and the transformer capacity electricity charge are calculated respectively through the maximum demand electricity charge and the transformer capacity electricity charge, the actual electricity charges of the two charging modes are calculated from the actual angle, and the method is closer to the relevant policies, so that the data of the maximum demand charging mode are more accurate. And judging whether the transformer capacity electric charge-maximum demand electric charge is more than 0, if so, indicating that the user adopting the maximum demand charging mode has the maximum demand space, and if not, indicating that the transformer capacity electric charge-maximum demand electric charge is less than 0, if so, indicating that the user adopting the maximum demand charging mode does not have the maximum demand space. The profit and loss results generated by the maximum demand charging mode relative to the transformer capacity charging mode can be clearly displayed through a simple comparison algorithm. The method is more intuitive.
finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
