Referring to fig. 1, fig. 1 is a flowchart of an active power adjusting method for a charging pile according to an embodiment of the present invention.
Referring to fig. 1, in the embodiment of the present invention, a charging pile active power adjusting method includes:
s101: the method comprises the steps of collecting the real-time electricity price of the current collection time period in the day of the charging pile and the day-ahead electricity price of the same collection time period in the day of the charging pile.
Taking the collection period as 15 minutes, there will be 96 collection periods in one day. In this step, the real-time electricity prices of the current collection time period in the current day and the day-ahead electricity prices of the same collection time period in the previous day are collected. In general, the day ahead is collected once, and the day ahead electricity price is usually corresponding to each collection time period in the previous day.
Specifically, in the embodiment of the present invention, the real-time electricity price may be a real-time electricity price of an area where a single charging pile is located; the day-ahead electricity price can be the day-ahead electricity price of the area where the single charging pile is located. When acquireing above-mentioned price of electricity promptly, can be directed against the regional price of electricity that acquires of single electric pile place, including real-time price of electricity and day-ahead price of electricity. Because their electricity prices are generally the same in the same area. And if different charging piles cross the region, the electricity price of the charging piles may also change. Therefore, when the real-time electricity price and the day-ahead electricity price are obtained in this step, the real-time electricity price and the day-ahead electricity price are usually obtained by targeting the area where the single charging pile is located, and the average electricity price across a plurality of areas is usually not 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 located; the day-ahead electricity price is the day-ahead electricity price of the area where the single charging pile is located.
S102: and 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 collection time period is subtracted by the 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 substantially reflect the relative change of the electricity supply and demand in the power grid between two days at the same time. Obviously, the larger the electricity price difference value is, the more tense the electricity supply and demand in the power grid at the same moment today is compared with the bidding at the day. Otherwise, the power 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 present invention, the power control coefficient is inversely proportional to the electricity price value. That is, the power control coefficient is smaller as the above-described electricity price difference value is larger. Otherwise, the larger 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 in the embodiment of the present invention is typically 1. 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 specifically by a table lookup method or the like, and specific contents thereof will be described in detail in the following embodiments of the present invention, which are not described herein again.
S104: and issuing a control command corresponding to the power control coefficient to the charging pile so that the charging pile controls the output power to be the actual power according to the control command.
In the embodiment of the present invention, the actual power is a product of an actual charging required power corresponding to the charging pile and the power control coefficient. That is, the lower the power control coefficient is, the lower the actual power output by the charging pile is. The actual charging demand power is charging power required for charging an object to be charged, such as an electric vehicle to be charged.
In this step, a control command corresponding to the power control coefficient is issued to the charging pile, where the control command at least represents the magnitude of the power control coefficient calculated in the step S103. Generally, the control command may include a power control coefficient so that the charging pile controls the output power.
In the embodiment of the invention, after the charging pile acquires the control command, the control command 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 the power grid is controlled at the terminal, and the electric quantity of the power grid is balanced.
The embodiment of the invention provides a charging pile active power adjusting method, which comprises the following steps: acquiring the real-time electricity price of the current acquisition time period in the charging pile day and the day-ahead electricity price of the same acquisition time period in the charging pile day; 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; 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 value; the control instruction corresponding to the power control coefficient is issued 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 actual charging demand power corresponding to the charging pile and the power control coefficient.
The electricity price can reflect the level of the electricity supply and demand in the power grid, and the electricity price difference can reflect the fluctuation of the electricity supply and demand of the power grid. The electric quantity supply and demand level of the current collection time period can be determined by calculating the electricity price difference value of the same collection time period in two days, and the output power of the charging pile is controlled by determining the power control coefficient according to the electricity price difference value, wherein the larger the electricity price difference is, the more tense the electric quantity supply and demand of the current collection time period is, so that the output power of the charging pile can be reduced to balance the electricity demand of the terminal. And 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.

In this step, the power price difference obtained by the above calculation is compared with the price threshold, and it is specifically required to determine a ratio of the power price difference to the price threshold, in other words, a multiple between the power price difference and the price threshold.
S204: and searching the power control coefficient corresponding to the ratio from a preset price difference coefficient table.
In the embodiment of the present invention, the power control coefficient corresponds to the ratio. And the preset valence coefficient table stores the corresponding relation between the power control coefficient and the ratio. Therefore, in this step, the power control coefficient corresponding to the above ratio can be determined according to a table lookup method.
Specifically, the correspondence relationship includes: and when the ratio is less than 1, determining that the power control coefficient is 1. That is, 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, that is, the electricity price value is less than the price threshold value. The specific correspondence relationship in the valence coefficient table may be as shown in table 1 below, but the correspondence relationship shown in table 1 is merely an example, and the correspondence relationship is not limited to the specific one.

The expected output power of the corresponding charging pile can be calculated by itself according to the actual charging required power and the output power obtained in the step S206 and the power control coefficient determined in the step S204, that is, the actual charging required 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 the above step S206, and when the expected output power and the output power are matched, it indicates that the charging pile is supplying power normally; when the two are not matched, the charging pile is indicated to be abnormal in power supply, and the alarm can be given for maintenance.
S208: and when the current time exceeds the acquisition time period, adjusting the output power of the charging pile to the actual charging required power.
In this step, if the current time is not within the collection time period, 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 required power, so that the output of the charging pile is controlled continuously through the flow in the next calculation turn.
