Detailed Description
The embodiment of the invention provides a characterization method and a characterization device for operation characteristics of a power distribution network, which are used for determining electricity fee pricing according to real-time load of a line and line information, thereby roughly determining the equipment utilization rate of the power distribution network based on the electricity fee pricing and determining whether the looped network operation mode of the power distribution network needs to be adjusted.
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a flowchart of steps of an embodiment of a method for characterizing operating characteristics of a power distribution network according to the present invention is shown, where the method includes:
s1, acquiring the real-time line load, the maximum excitation load, the total ring network standby margin and the standby capacity of the line where the target user is located;
the method specifically comprises the following steps:
acquiring an excitation factor and a maximum value of historical load of a line where the target user is located;
and taking the product of the excitation factor and the maximum value of the historical load as the maximum excitation load.
In the embodiment of the present invention, the spare capacity refers to a spare load value required by the line obtained by subtracting the maximum historical load value of the line from the real-time operation value, and indicates that the current line should provide enough spare capacity to meet the maximum possible requirement of the current line. The formula for spare capacity is:
Xrest=Xmax-Xtime
and the incentive factor represents the percentage of the power supply enterprises in the year which encourages the electricity on a certain side circuit to increase, and the power supply enterprises can improve the total electricity consumption of the society by adjusting the incentive factor.
Meanwhile, the total spare margin of the ring network is a margin value for ensuring the power utilization reliability of each user in the ring network line, and the size of the margin value is expressed by a formula as follows:
Figure BDA0003311203630000061
s2, determining a target electricity price algorithm calculation formula of the target user based on the numerical relationship among the line real-time load, the maximum excitation load, the ring network total standby margin and the standby capacity;
the method specifically comprises the following steps:
when the line real-time load is smaller than or equal to the maximum excitation load and the ring network total spare margin is smaller than the spare capacity, selecting a first electricity price calculation formula as a target electricity price algorithm calculation formula of the target user;
when the line real-time load is smaller than or equal to the maximum excitation load and the ring network total spare margin is larger than or equal to the spare capacity, selecting a second electricity price calculation formula as a target electricity price algorithm calculation formula of the target user;
and when the real-time load of the line is greater than the maximum excitation load and the total spare margin of the ring network is smaller than the spare capacity, selecting a third electricity price calculation formula as a target electricity price algorithm calculation formula of the target user.
In the embodiment of the present invention, there may be three possibilities for the power utilization situation of the target user in combination with the line thereof:
(1) the total spare margin of the ring network of the line where the target user is located is enough; in this case, it is described that the device of the line is in a low-usage state, and at this time, the electricity fee that the target user needs to pay is only composed of three parts, namely, the basic power supply electricity price, the local side standby electricity price, and the other side standby electricity price, and then the first electricity price calculation formula is selected as the target electricity price algorithm calculation formula of the target user. Therefore, the power supply cost and the price of electricity in the market under normal conditions are reflected to a certain extent.
(2) The total standby margin of the looped network of the line where the target user is located is enough, and the power utilization condition of the target user is increased; in this case, when the real-time load of the line where the target user is located exceeds the historical maximum value, the current real-time load is used as the historical load maximum value of the line, and the second electricity price calculation formula is selected as the target electricity price algorithm calculation formula of the target user. The incentive factors are integrated into a basic algorithm of the electricity charge pricing, and the self-adaptive incentive function facing the maximum historical load is provided.
(3) The total spare margin of the ring network of the line where the target user is located is insufficient; when the total spare margin of the ring network is insufficient, the reliability of power supply to each user in the ring network is difficult to determine, at the moment, another power rate calculation mode is needed to suppress the power consumption situation of the target user, at the moment, a third power rate calculation formula is selected as the target power rate calculation formula of the target user, so that the power consumption increase of the user is suppressed, and warning signals are provided for the power supply mode and the power grid construction strategy adjustment.
In specific implementation, for the condition that the total spare margin of the ring network is insufficient, a power supply enterprise can consider to expand the power grid or adjust the ring network operation mode of the power distribution network according to the overload operation condition, otherwise, the overload condition continues all the time, so that the user load is forced to be cut off, and the operation reliability of the power grid is reduced.
