It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart of a method for adjusting active power of a charging pile according to an embodiment of the invention.
Referring to fig. 1, in an embodiment of the present invention, a method for adjusting active power of a charging pile includes:
s101: and collecting the real-time electricity price of the current collecting time period in the day of the charging pile, and the day-ahead electricity price of the same collecting time period before the day of the charging pile.
Taking the duration of the collection period as an example of 15 minutes, there are 96 collection periods in a day. In this step, the real-time electricity price of the current collection period and the day-ahead electricity price of the same collection period of the previous day are collected. Typically, the day-ahead electricity prices corresponding to the respective collection periods in the previous day are collected once.
Specifically, in the embodiment of the present invention, the real-time electricity price may be the real-time electricity price of the area where the single charging pile is located; the day-ahead electricity price may be a day-ahead electricity price of an area where the single charging pile is located. When the electricity price is obtained, the electricity price is obtained for the area where the single charging pile is located, including real-time electricity price and day-ahead electricity price. Because in the same area, the electricity prices are generally the same. However, if different charging piles are located across the area, the electricity price may also change. Therefore, when the real-time electricity rate and the day-ahead electricity rate are obtained in this step, the real-time electricity rate and the day-ahead electricity rate are usually obtained with the area where the single charging pile is located as a target, and the average electricity rate across a plurality of areas is not usually obtained. Correspondingly, in the embodiment of the invention, the real-time electricity price is the real-time electricity price of the area where the single charging pile is positioned; and the day-ahead electricity price is the day-ahead electricity price of the area where the single charging pile is located.
S102: subtracting the day-ahead electricity price from the real-time electricity price in the same acquisition time period to obtain an electricity price difference value corresponding to the acquisition time period.
In this step, the electricity price difference value in the same collection time period is calculated, specifically, the current real-time electricity price in the current collection time period is subtracted by the current day-ahead electricity price in the same collection time period, so as to obtain the electricity price difference value corresponding to the same collection time period. In the embodiment of the invention, the electricity price difference value can generally reflect the relative change of electricity supply and demand in the power grid at the same time between two days. Obviously, the larger the electricity price difference value is, the more tension is applied to the electricity supply and demand in the power grid at the same moment today compared with the day-ahead bidding. Otherwise, the electricity supply and demand are relatively abundant.
S103: and determining a corresponding power control coefficient according to the electricity price difference value.
In an embodiment of the invention, the power control coefficient is inversely proportional to the electricity price difference. I.e. the larger the above-mentioned electricity price difference, the smaller the power control coefficient. Conversely, the greater the power control coefficient. Typically, the power control coefficient has a maximum value in the embodiment of the present invention, and the maximum value of the power control coefficient is typically 1 in the embodiment of the present invention. I.e. the value of the power control coefficient does not exceed 1.
In this step, the corresponding power control coefficient may be determined according to the electricity price difference by a table lookup method or the like, and the specific content thereof will be described in detail in the following embodiments of the present invention, which will not be described herein.
S104: and sending a control instruction corresponding to the power control coefficient to the charging pile, so that the charging pile controls the output power to be actual power according to the control instruction.
In the embodiment of the invention, the actual power is the product of the power control coefficient and the actual charging demand power corresponding to the charging pile. I.e. the lower the power control coefficient, the lower the actual power output by the charging pile. The actual charging power is the charging power required when an object to be charged, such as an electric vehicle to be charged, is charged.
In this step, a control instruction corresponding to the power control coefficient is issued to the charging pile, where the control instruction may at least characterize the magnitude of the power control coefficient calculated in S103. Typically, the control command may include a power control coefficient so that the charging pile controls its output power.
In the embodiment of the invention, after the charging pile acquires the control instruction, the control instruction is analyzed to acquire the corresponding power control coefficient. And then, the charging pile can multiply the actual charging demand power corresponding to the current object to be charged by the power control coefficient, so that the actual output power of the charging pile is calculated and output, the output of a power grid is controlled at a terminal, and the electric quantity of the power grid is balanced.
The charging pile active power adjusting method provided by the embodiment of the invention comprises the following steps: collecting real-time electricity prices of the current collecting time period in the day of the charging pile, and collecting day-ahead electricity prices of the same collecting time period before the day of the charging pile; subtracting the current price from the real-time current price in the same acquisition time period to obtain a current price difference value corresponding to the acquisition time period; determining a corresponding power control coefficient according to the electricity price difference value; the power control coefficient is inversely proportional to the electricity price difference; transmitting a control instruction corresponding to the power control coefficient to the charging pile, so that the charging pile controls the output power to be actual power according to the control instruction; the actual power is the product of the power of the charging pile corresponding to the actual charging demand and the power control coefficient.
The electricity price can reflect the electricity supply and demand level in the power grid, and the electricity price difference can reflect the fluctuation of the electricity supply and demand of the power grid. The power supply and demand level of the current collection time period can be determined by calculating the power price difference value of the same collection time period for two days, and the output power of the charging pile is controlled by determining the power control coefficient according to the power price difference value, wherein the larger the power price difference value is, the more tense the power supply and demand of the current collection time period is, so that the output power of the charging pile can be regulated down to balance the power demand of the terminal. The power control coefficient is calculated through the electricity price difference, the calculation process is simple and quick, the real-time performance is high, and the requirement on calculation resources is low.
The specific content of the charging pile active power adjusting method provided by the invention will be described in detail in the following embodiments of the invention.
Referring to fig. 2, fig. 2 is a flowchart of a specific active power adjustment method for a charging pile according to an embodiment of the present invention.
Referring to fig. 2, in an embodiment of the present invention, a method for adjusting active power of a charging pile includes:
s201: and collecting the real-time electricity price of the current collecting time period in the day of the charging pile, and the day-ahead electricity price of the same collecting time period before the day of the charging pile.
S202: subtracting the day-ahead electricity price from the real-time electricity price in the same acquisition time period to obtain an electricity price difference value corresponding to the acquisition time period.
The above S201 to S202 are substantially identical to S101 to S102 in the above embodiment of the present invention, and the detailed description will be omitted herein for reference to the above embodiment of the present invention.
S203: and comparing the electricity price difference value with a price threshold value, and determining the ratio of the electricity price difference value to the price threshold value.
In this step, a price threshold may be specifically set first, and the price threshold is usually a natural number greater than 0. The price threshold may be set according to actual situations, and the specific value of the price threshold is not specifically limited in the embodiment of the present invention.
In this step, the calculated electricity price difference is compared with the price threshold, and the ratio of the electricity price difference to the price threshold is specifically determined, in other words, the multiple between the electricity price difference and the price threshold is determined.
S204: and searching the power control coefficient of the corresponding ratio from a preset price difference coefficient table.
In the embodiment of the invention, the correspondence between the power control coefficient and the ratio is realized. And the preset price difference coefficient table stores the corresponding relation between the power control coefficient and the ratio. Therefore, in this step, the corresponding power control coefficient can be determined based on the above ratio according to the table look-up method.
Specifically, the correspondence relationship includes: and when the ratio is smaller than 1, determining that the power control coefficient is 1. I.e. a column in the price difference coefficient table may indicate that the power control coefficient is determined to be 1 when the ratio is less than 1, i.e. the electricity price difference is less than the price threshold. The specific correspondence relation in the valence coefficient table may be shown in table 1 below, and the correspondence relation shown in table 1 is merely illustrative and is not limited in any way.
TABLE 1 valence Difference coefficient table
A is as described above i Is the electricity price difference value, k 1 The price threshold value is given, and k is the power control coefficient. From table 1 above, the required power control coefficients can be determined in this step.
S205: and sending a control instruction corresponding to the power control coefficient to the charging pile, so that the charging pile controls the output power to be actual power according to the control instruction.
The step is basically identical to S104 in the above embodiment of the present invention, and the detailed description will be omitted herein with reference to the above embodiment of the present invention.
S206: and acquiring the actual charging demand power and the real-time output power of the same charging pile.
In this step, the actual charging demand power corresponding to the same charging pile and the real-time output power of the charging pile can also be obtained, so as to monitor the state of the charging pile.
S207: and determining the working state of the charging pile according to the actual charging demand power, the output power and the power control coefficient.
According to the actual charging demand power and the output power obtained in S206 and the power control coefficient determined in S204, the expected output power of the corresponding charging pile can be calculated by itself, i.e. the actual charging demand power is multiplied by the power control coefficient to obtain the expected output power. Then, in this step, the expected output power may be compared with the output power obtained in S206, and when the two match, it indicates that the charging pile is supplying power normally; when the two do not coincide, the abnormal power supply of the charging pile is indicated, and an alarm can be given to maintain.
S208: and when the current time exceeds the acquisition time period, adjusting the output power of the charging pile to the actual charging demand power.
In this step, if the current time does not fall within the above-mentioned collection time period, and the output of the charging pile needs to be restored when the collection time period is exceeded, that is, the output power of the charging pile is adjusted to the actual charging demand power, so that the next calculation round continues to control the output of the charging pile through the above-mentioned flow.
According to the active power adjusting method for the charging pile, provided by the embodiment of the invention, the electricity price difference value of the same collecting time period in two days is calculated, the electricity supply and demand level of the current collecting time period can be determined, and the power control coefficient is determined according to the electricity price difference value to control the output power of the charging pile, wherein the larger the electricity price difference is, the more tense the electricity supply and demand of the current collecting time period is, so that the output power of the charging pile can be adjusted down to balance the electricity demand of a terminal.
