Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. 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.
The first embodiment of the invention provides a processing method for dynamic regulation of charging power, as shown in fig. 1, which is a schematic diagram of the processing method for dynamic regulation of charging power, and the method mainly includes the following steps:
step 1, taking the rated power distribution total power of the current power distribution station as the corresponding first rated total power and storing the same; and the real-time civil electricity output total power of the current power distribution station area is periodically sampled according to a preset sampling frequency to generate and store a corresponding first civil real-time total power.
Here, the implementation subject of the method of the embodiment of the present invention is any apparatus, device, server, system or platform that can provide the processing steps of the method of the embodiment of the present invention for each distribution substation; the implementation main body needs to be connected with a main transformer of the current distribution area, namely the current distribution area, and also needs to be connected with each charging equipment (a charging unit and a charging pile) of a charging network of the current distribution area; the implementation main body can obtain rated power distribution total power of the current power distribution station area from the main transformer through a connecting channel with the main transformer, and can also obtain real-time civil power output total power from the main transformer so as to finish corresponding sampling operation to obtain first civil real-time total power; the sampling frequency is a preset frequency value, and the sampling frequency can be allocated according to actual application requirements; based on the input and output peer-to-peer principle of the transformer, the difference between the rated distribution total power and the civil electricity output total power is practically equal to the maximum available electricity total power of the charging network of the current distribution station.
It should be noted that, the device types of the charging device in the embodiment of the present invention at least include two types of charging units and charging piles, and in addition: 1) each charging device has a unique device identification code, 2) each charging device belongs to a specific charging service operator, of course, one charging service operator can correspond to a plurality of charging devices, 3) each charging device has a rated operating voltage in its device factory parameters, 4) each charging device needs to be installed in the field before being put into use, that is, each charging device corresponds to an installation position coordinate, and 5) each charging device locally presets a maximum available power parameter.
The charging equipment controls the real-time charging power of the charging equipment based on the preset maximum available power parameter so that the real-time charging power always does not exceed the maximum available power parameter; here, the real-time charging power of each charging device is the sum of the real-time self-power consumption power and the real-time charging output power, that is: real-time charging power = real-time self-power consumption power + real-time charging output power; when the equipment type of the charging equipment is a charging unit, the charging equipment is used for charging an external energy storage battery, and the corresponding charging output power is the output power generated when the energy storage battery is charged; when the equipment type of the charging equipment is a charging pile, the charging equipment is used for charging an external new energy vehicle, and the corresponding charging output power is the output power generated when the new energy vehicle is charged.
Step 2, identifying whether the current time enters a set electricity utilization peak period; if yes, setting a corresponding dynamic regulation mode as a first mode; if not, setting the corresponding dynamic regulation mode as a second mode;
wherein the electricity consumption peak period comprises one or more time periods; the dynamic regulation mode comprises a first mode and a second mode.
Here, the embodiment of the present invention provides that the dynamic regulation mode is set to the first mode whenever the current time enters any one of the electricity consumption peak periods, whereas the dynamic regulation mode is set to the second mode if the current time is not within all the time periods specified by the electricity consumption peak periods.
Step 3, when the dynamic regulation mode is the first mode, the first civil real-time total power with the latest time is used as the corresponding current civil real-time total power; the parameters of a locally preset charging equipment parameter table are updated according to the first rated total power and the current civil real-time total power;
the method specifically comprises the following steps: step 31, when the dynamic regulation mode is the first mode, the first civil real-time total power with the latest time is used as the corresponding current civil real-time total power;
step 32, carrying out parameter updating on a locally preset charging equipment parameter table according to the first rated total power and the current civil real-time total power;
here, when the dynamic regulation mode is the first mode, the embodiment of the invention updates the charging equipment parameter table based on the power difference between the first rated total power and the current civil real-time total power as a reference;
the method specifically comprises the following steps: step 321, subtracting the current civil real-time total power from the first rated total power to obtain a corresponding current charging available total power;
Step 322, calculating the sum of the first maximum available power fields of all the first parameter records in the charging equipment parameter table to obtain a corresponding first power sum;
the charging equipment parameter table comprises a plurality of first parameter records; each first parameter record corresponds to a charging device; the first parameter record includes a first device identification field, a first type field, a first coordinate field, a first operator field, a first power rating field, and a first maximum available power field; the first type field comprises a charging unit and a charging pile; the first maximum available power field is less than or equal to the first rated power field;
the first equipment identification field is the equipment identification code of the corresponding charging equipment, the first type field is the equipment type of the corresponding charging equipment, the first coordinate field is the installation position coordinate of the corresponding charging equipment, the first operator field is the operator identification code of the charging service operator to which the corresponding charging equipment belongs, the first rated power field is the rated working voltage in the equipment factory parameters of the corresponding charging equipment, and the first maximum available power field corresponds to the maximum available power parameter preset locally for the corresponding charging equipment; as known from common knowledge, the rated operating voltage is a safe operating voltage limit value of the device, if the real-time operating voltage exceeds the rated operating voltage, the device may be damaged, so that a locally preset maximum available power parameter of the charging device cannot exceed the corresponding rated operating voltage, and a natural first maximum available power field cannot exceed a corresponding first rated power field;
The first power sum obtained in the current step in the embodiment of the invention is actually the maximum available power sum of all charging devices in the current charging network;
step 323, calculating the absolute power difference between the total power available for current charging and the sum of the first power to obtain a corresponding first absolute power difference; calculating the ratio of the first absolute power difference to the first power sum to obtain a corresponding first ratio;
step 324, when the first ratio does not exceed the preset small fluctuation ratio threshold, or when the first ratio has exceeded the small fluctuation ratio threshold but the total power available for charging is greater than or equal to the first power sum, the charging equipment parameter table is not updated and the update processing is ended;
here, the small fluctuation ratio threshold is a preset positive ratio threshold with smaller value;
when the first ratio does not exceed the small fluctuation ratio threshold, the difference between the total power available for current charging and the total sum of the first power is not large, and at the moment, in order to ensure the working stability of the power grid, the embodiment of the invention does not dynamically regulate and control any charging equipment in the charging network and does not naturally update the parameter table of the charging equipment;
When the first ratio exceeds the small fluctuation ratio threshold but the total power available for current charging is greater than or equal to the first power sum, although the difference between the total power available for current charging and the first power sum can obviously regulate and control the charging equipment in the charging network based on the total power available for current charging, the charging equipment parameter table is updated by using the total power available for current charging which is not lower than the first power sum and the risk of reducing the electricity consumption of the civil network is caused by the regulation implemented by the operation of the subsequent steps, so that the embodiment of the invention does not update the charging equipment parameter table;
step 325, traversing all first parameter records of the charging device parameter table when the first ratio has exceeded the small fluctuation ratio threshold and the total power available for charging is less than the first power sum; the first parameter record of the current traversal is used as a corresponding current parameter record in traversing, the ratio of the first maximum available power field of the current parameter record to the sum of the first powers is calculated to obtain a corresponding second ratio, the product of the second ratio and the total power available for current charging is used as a corresponding first power, and the first maximum available power field of the current parameter record is updated to be the corresponding first power when the first power is smaller than or equal to the first rated power field of the current parameter record; and ending the update processing process when the traversal is finished;
Here, when the first ratio exceeds the small fluctuation ratio threshold and the total power available for current charging is smaller than the first power sum, the difference between the total power available for current charging and the first power sum is obvious and the trend of reduction is shown, if the total power available for current charging is lower than the first power sum, the effect of expanding the electricity consumption of the civil electric network can be achieved, and the requirement of guaranteeing the electricity consumption stability of the civil electric network in the electricity consumption peak period can be met. When updating the charging equipment parameter table, the embodiment of the invention takes the maximum available power before each charging equipment as a reference, and calculates the new maximum available power, namely the first power, according to the second ratio which is the duty ratio relation between the maximum available power before each charging equipment and the sum of the first powers.
Step 4, when the dynamic regulation mode is the second mode, calculating average power of the first civil real-time total power acquired in the latest appointed duration T to generate corresponding first civil average total power; parameter updating is carried out on the charging equipment parameter table according to the first rated total power and the first civil average total power;
The method specifically comprises the following steps: step 41, when the dynamic regulation mode is the second mode, calculating average power of the first civil real-time total power acquired in the latest appointed duration T to generate corresponding first civil average total power;
step 42, updating parameters of the charging equipment parameter table according to the first rated total power and the first civil average total power;
the method specifically comprises the following steps: step 421, the difference obtained by subtracting the first civil average total power from the first rated total power is taken as the corresponding current charging available total power;
here, when the dynamic regulation mode is the second mode, the embodiment of the invention updates the charging equipment parameter table based on the power difference between the first rated total power and the first civil average total power as a reference;
