The terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, etc. The server 104 may be implemented as a stand-alone server or as a server cluster of multiple servers.
In one embodiment, as shown in fig. 2, a dc power control method is provided, and the method is applied to the terminal 102 in fig. 1 for illustration, and includes the following steps:
s202: acquiring a issued direct current power curve, a plurality of power adjustment points in the issued direct current power curve and direct current power target values corresponding to the power adjustment points; the power adjustment points are ordered according to time.

The terminal calculates the difference between the current direct current power and the direct current power target value corresponding to the first power adjusting point, divides the difference by a time interval to obtain a first power adjusting rate, judges whether the first power adjusting rate meets the adjusting rate requirement condition, and if the first power adjusting rate does not meet the adjusting rate requirement condition, the adjusting rate requirement condition means that the first adjusting rate is smaller than a preset threshold value, the power adjusting rate is larger, and the direct current power changes in a large range in a short time to cause power grid frequency fluctuation, so that stable operation of the power grid is not facilitated. At this time, the terminal determines, based on the issued dc power curve, a second power adjustment point at a next time corresponding to the first power adjustment point, and a target power value and time corresponding to the second power adjustment point.
S208: and calculating a second power regulation rate based on the direct current power target value and the current direct current power corresponding to the second power regulation point, judging whether the second power regulation rate meets the regulation rate requirement condition, and controlling the current direct current power according to the second power regulation rate under the condition that the second power regulation rate meets the regulation rate requirement condition.

In general, since the time difference between the time corresponding to the second power adjustment point and the current time is greater than 5 minutes, the situation that the second power condition rate does not meet the rate condition requirement condition does not occur, and in some extreme cases, if the second power condition rate does not meet the rate condition requirement condition, an error may occur in the issued dc power curve, and the dc power adjustment cannot be performed according to the power adjustment point in the dc power curve.
In the direct current power control method, the issued direct current power curve, the plurality of power adjustment points in the issued direct current power curve and the direct current power target value corresponding to each power adjustment point are obtained, the first power adjustment point at the next moment corresponding to the current direct current power is determined based on the issued direct current power curve, the first power adjustment rate is calculated based on the direct current power target value corresponding to the first power adjustment point and the current direct current power, whether the first power adjustment rate meets the adjustment rate requirement condition is judged, the second power adjustment point at the next moment corresponding to the first power adjustment point is determined under the condition that the first power adjustment rate does not meet the adjustment rate requirement condition, the second power adjustment rate is calculated based on the direct current power target value corresponding to the second power adjustment point and the current direct current power, whether the second power adjustment rate meets the adjustment rate requirement condition is judged, the current direct current power is controlled according to the second power adjustment rate, the condition that the second power adjustment rate meets the adjustment rate requirement condition is not exceeded, the accuracy of the direct current power can be guaranteed, and the power grid running stability is guaranteed.
In one embodiment, the step of determining whether the first power adjustment rate meets an adjustment rate requirement condition comprises: and under the condition that the first regulation rate is smaller than or equal to a preset rate threshold value, determining that the first power regulation rate meets the regulation rate requirement condition.
The terminal firstly determines a preset speed threshold, and when the threshold is set, a plurality of factors such as load change amplitude, generator inertia and the like need to be considered. For example, in the case where the load variation is small, the power adjustment rate may be set to 0.5MW/s, and in the case where the load variation is large, the power adjustment rate may be set to 1MW/s. And under the condition that the first regulation rate is smaller than or equal to a preset rate threshold, the terminal determines that the first power regulation rate meets the regulation rate requirement condition.
In this embodiment, under the condition that the first adjustment rate is less than or equal to the preset rate threshold, it is determined that the first power adjustment rate meets the adjustment rate requirement condition, so that the power adjustment rate is not more than the rate threshold, the direct current power value is accurately adjusted, and therefore running stability of the power grid is guaranteed.
In one embodiment, the step of controlling the current dc power at the second power adjustment rate comprises: under the condition that the second power regulation rate is a positive value, increasing the current direct current power according to the second power regulation rate until the current direct current power reaches a direct current power target value corresponding to the second power regulation point; and under the condition that the second power regulation rate is negative, reducing the current direct current power according to the second power regulation rate until the current direct current power reaches a direct current power target value corresponding to the second power regulation point.
The terminal determines a direct current power target value corresponding to the second power adjustment point, and if the direct current power target value is 100W, the terminal firstly judges whether the second power adjustment rate is positive or negative, if so, the current direct current power is gradually increased according to the second power adjustment rate until the current direct current power reaches the target value of 100W, and if so, the current direct current power is gradually decreased according to the second power adjustment rate until the current direct current power reaches the target value of 100W.
In this embodiment, the current dc power is increased according to the second power adjustment rate when the second power adjustment rate is a positive value, until the current dc power reaches the dc power target value corresponding to the second power adjustment point, and the current dc power is reduced according to the second power adjustment rate when the second power adjustment rate is a negative value, until the current dc power reaches the dc power target value corresponding to the second power adjustment point, so that the dc power value can be accurately adjusted, and the running stability of the power grid is ensured.
In one embodiment, the method further comprises: and under the condition that the first power regulation rate meets the regulation rate requirement condition, controlling the current direct current power according to the first power regulation rate.
Under the condition that the first power adjustment rate meets the adjustment rate requirement condition, the terminal directly controls the current direct current power according to the first power adjustment rate, and only under the condition that the first power adjustment rate does not meet the adjustment rate requirement condition, the terminal needs to calculate the second power adjustment rate.
In this embodiment, when the first power adjustment rate meets the requirement of adjusting the rate, the current dc power is controlled according to the first power adjustment rate, so that the power adjustment rate is not more than the rate threshold, and the dc power value is accurately adjusted, thereby ensuring the running stability of the power grid.
In one embodiment, the method further comprises: and under the condition that the second power adjustment rate does not meet the rate adjustment requirement condition, updating the power adjustment point at the next moment corresponding to the second power adjustment point into a new second power adjustment point, returning to the step of calculating the second power adjustment rate based on the direct current power target value and the current direct current power corresponding to the second power adjustment point, and continuing to execute.
Under the condition that the second power adjustment rate does not meet the adjustment rate requirement condition due to special conditions, the terminal determines a power adjustment point at the next moment corresponding to the second power adjustment point based on the issued direct current power curve, updates the power adjustment point into a new second power adjustment point, and calculates the second power adjustment rate again based on a direct current power target value and the current direct current power corresponding to the second power adjustment point so as to judge whether the updated second power adjustment rate meets the adjustment rate requirement condition.
In this embodiment, when the second power adjustment rate does not meet the rate adjustment requirement condition, the power adjustment point at the next moment corresponding to the second power adjustment point is updated to be a new second power adjustment point, and the step of obtaining the second power adjustment rate by calculation based on the direct current power target value and the current direct current power corresponding to the second power adjustment point is returned, and the step is continuously executed, so that it is ensured that the power adjustment rate does not exceed the rate threshold value, the direct current power value is accurately adjusted, and therefore the running stability of the power grid is ensured.
In one embodiment, the method further comprises: and for the subsequent issued direct current power curve, judging whether a first power adjustment point exists at the next moment corresponding to the current direct current power based on the issued direct current power curve, and returning to the step of determining the first power adjustment point at the next moment corresponding to the current direct current power based on the issued direct current power curve and continuously executing the step if the first power adjustment point exists at the next moment corresponding to the current direct current power.
After receiving a dc power curve issued by a server, the terminal first determines whether a first power adjustment point exists at a next time corresponding to the current dc power, if so, calculates a first power adjustment rate based on a dc power target value corresponding to a new first power adjustment point, and determines whether the first power adjustment rate at this time meets an adjustment rate requirement condition, so as to control the current dc power.
In this embodiment, by determining, according to the subsequent issued dc power curve, whether the first power adjustment point exists at the next time corresponding to the current dc power based on the issued dc power curve, and if so, returning to the step of determining the first power adjustment point at the next time corresponding to the current dc power based on the issued dc power curve and continuing to execute the step, it is possible to ensure that the adjustment rate of the dc power does not exceed the limit, and accurately adjust the dc power value, thereby ensuring the running stability of the power grid.
